Ptorx docs


  • Email Aliases, alias emails, or forwarding emails
    • Email addresses created via Ptorx that typically act as a middleman for your primary emails by receiving mail and forwarding allowed mail to your primary email addresses.
  • Waterfall
    • Every alias has a waterfall that allows you to link filters, modifiers, and primary emails to it in a specific order. Each linked item is acted on in order, cascading downward like a waterfall, allowing you to redirect different mail to different primary emails based on filters and modifiers.
  • Primary Emails, real, or main emails
    • Your actual email addresses where you normally receive mail. These emails are where mail sent to your alias addresses will be redirected to. Enable Autolink to automatically link them to any new aliases you create.
  • Filters
    • Filters allow you to filter out mail (with whitelists or blacklists) before it reaches any primary emails that come after it in an alias's waterfall.
  • Modifiers
    • Modifiers allow you to modify components of an incoming email before it gets redirected to primary emails below it in an alias's waterfall.
  • Messages, or mail
    • Messages are any incoming pieces of mail received by your alias addresses.
  • Keys, or PGP keys
    • Your optional private and public keys which will be used to encrypt the text and HTML body contents of mail stored on Ptorx servers. Mail is encrypted by Ptorx servers with your public key and decrypted later in the app using the private key.
  • Mailbox Password
    • Separate from your account password, this is used to encrypt your private key if you have one. It's important this is a strong password because your encrypted private key will be stored on Ptorx for convenience. Only you, with your access to this password, will be able to read your encrypted mail.


Deleting aliases

By deleting an email alias, that specific email is completely removed from your account, however it remains on Ptorx's system simply as a placeholder to prevent that address from ever being claimed again in the future. This means that once you delete an alias address there is no way for you or another user to claim that address. Deleted aliases will not forward or save received mail.

Replying to forwarded mail

You can safely reply to mail that is sent to an alias if that alias has Allow Anonymous Reply enabled. You can reply to this mail either from within the Ptorx app or by replying to the message you received in your email client as you would reply to any other message.

There are some limitations with this feature:

  • You will only be able to reply to mail so long as a copy of it is still stored on Ptorx.
  • If you reply to mail from within your email client, that client must support the Reply-To email header. Most popular clients (like Gmail) should support this.

The replies will be sent to the original sender using the address of the alias that received the message.

Forwarded mail marked as spam

Due to the nature of the service and for very technical reasons we won't bother with here, sometimes forwarded mail will end up in your spam folder even though it's perfectly legitimate mail. The solution to this is to whitelist or whichever alias email domains or addresses you use. This process will differ based on your mailbox provider.

For Gmail, the most popular option, you'd create a filter for the domain ( or a specific address ( and set the Never send it to Spam action. Alternatively, you can also add individual addresses to your contacts whenever you receive a message by viewing the mail and selecting the Add to Contacts list option. A good tutorial can be found here.

Send mail from alias using another app

Each alias has unique SMTP authentication credentials that can be used to send mail from that alias using a third-party, non-Ptorx email client like Gmail or Outlook.

  • Host:
  • Port: 587
  • User:
  • Pass: SMTP passkey provided when viewing alias in-app.

Note: Sending mail programmatically using your credentials is forbidden.


Modifiers give you expanded control over the content of the mail that gets sent to you. Modifiers are only applied to mail being redirected to a main email. If you have 'Save Mail' enabled on an alias, the saved mail will be unmodified.


Special functions are available within templates allow you to access and manipulate email content. All functions are accessed via the """func()""" syntax, where func is the name of the function.

Get variables


Allows you to access variables from the message. Note that if a previous modifier has modified this variable then you will receive that modified value. If the variable does not exist then """var("...")""" will be removed and replaced with just an empty string.

Variables you can choose from:

  • from
  • to
  • subject
  • html - the message body as HTML
  • text - the message body as text


Email from: """var("from")"""


Email from:

Get Header Values


Allows you to access headers from the message. Note that if a previous modifier has modified this header then you will receive that modified header. If the header does not exist then """header("...")""" will be removed and replaced with just an empty string.


Send replies to: """header("reply-to")"""


Send replies to:

Find and replace

replace("var", "substr", "replacement")

Allows you to find and replace text within the specified variable. If the variable does not exist then """replace(...)""" will be removed and replaced with just an empty string.


Email from: """replace("from", "example", "domain")"""


Email from:

Find and replace with regular expressions

replace("var", regex(/pattern/flags), "replacement")

Allows you to find and replace text within the specified variable using JavaScript's regular expression engine. If the variable does not exist then """replace(...)""" will be removed and replaced with just an empty string.

Flags are optional. gimsuy may be used. See the Parameters: flags section on MDN for more information.

Special capabilities are enabled in the replacement value via the $ character:

  • $$: If you just want to insert a '$' character, you'll have to use $$.
  • $&: Inserts the matched substring.
  • $`: Inserts the portion of the string that precedes the matched substring.
  • $': Inserts the portion of the string that follows the matched substring.
  • $n: Where n is a non-negative integer lesser than 100, inserts the nth parenthesized submatch string.


Email from: """replace("from", regex(/(EXAMPLE|TEST)/gi), "domain")"""


Email from:


A domain on Ptorx is a normal domain name that can be used to create alias emails. All Ptorx users get access to the domain. Optionally, you can add your own domain to Ptorx, or request access to a domain added by another Ptorx user.

Using your own domain, or those used by few other users, can help circumvent blacklists.

Adding your domain to Ptorx

You can add your own domains to Ptorx, and use them to create aliases just like you would with a normal alias. This is available at no extra cost and you can add as many domains as you like!

After initiating the process of adding your domain to Ptorx, you must verify that you own the domain, so don't bother trying to add a domain you don't own. You will verify ownership by setting a few DNS records:

Type Hostname Value
TXT v=spf1 ~all
TXT v=DKIM1; k=rsa; p=...
MX should be whatever domain you entered into Ptorx. If you already have MX records set on your domain for another service, you should use a subdomain for mail that Ptorx will handle. Information for the second TXT record will be provided to you within the app.

For your MX record, you can set the priority to any number you like. 10 is typically the convention.

In certain cases it may take up to a day or two for these records to propagate. Use the 'verify' button when viewing your domain on Ptorx to check the values again. Mail will not be able to be received or sent until your domain is verified.

Removing or altering these records after verification will likely prevent your domain from working with Ptorx properly.

Requesting access to domains

If another user has already added a domain to Ptorx, you can request access to it by using the 'request access key' that is generated for you when you attempt to add the domain. You must send that key to the user who originally added the domain to Ptorx, and they must then authorize that key to use their domain.

A request key is used to prevent your account's information from needing to be shared with the domain owner.

Warning! Using another user's domain can be risky! If they decide to remove their domain from Ptorx, or don't renew its registration before it expires, you will lose access to any aliases you have created with that domain. They could also move their domain away from Ptorx which could potentially allow them to view your incoming mail!

Deleting a domain

Deleting a domain from your account if you are the domain's creator will result in all users of your domain, including you, losing any alias emails they have created with your domain. Your domain will be completely removed from Ptorx. You will be able to add your domain back to Ptorx in the future should you wish.

Deleting a user from your domain if you are the domain's creator will result in all of the user's aliases linked to your domain being deleted. The user will not be able to access your domain again without you authorizing their new request key.

Users of a domain must contact the domain's owner and request their account be removed as a user of the domain.


Credits are the currency with which actions on Ptorx are paid for. Sending, receiving, redirecting, and replying to mail all cost credits. Credits are awarded monthly based on your account tier.

Whenever your account runs out of credits, mail will no longer be received or redirected and you will not be able to send or reply to mail.


Action Cost
Send mail 1 credit
Receive mail 1 credit
Reply from app 1 credit
Reply from third-party inbox 2 credits
Forward to one primary email 2 credits

Note that the Forward action is really just a combination of the Send and Receive actions, as is the Reply from third-party inbox action. To clarify further: if someone sends you an email that is then redirected to one of your primary emails, that will only cost 2 credits. If it's forwarded to two primary emails, it will cost 3 credits.

Everything else on Ptorx can be done without charge.


Ptorx subscriptions allow full access to all of Ptorx's features while also increasing the amount of credits your account will be topped up to every month.

Premium and Ultimate users are able to do things that Basic users (free, non-paying) cannot:

  • Send mail from an alias on Ptorx
  • Have more than one primary email
  • Reply to mail using and alias on Ptorx
  • Save incoming mail to Ptorx for later viewing within the app
  • Reply to mail anonymously using an alias from your non-Ptorx mailbox
  • Send mail from an alias using its SMTP credentials in non-Ptorx email clients

Self-hosting Ptorx

Hosting Ptorx yourself gives you a greater level of control and privacy (assuming you set everything up correctly) but it does come at a cost: it's not a simple process. If you need a self-hosted Ptorx installation you can either follow this tutorial with no support should you get stuck, or you can hire us to do it for you by sending an email to Many steps will be vague and generalized, so you'll be expected to know how to fill in the blanks based on your environment and requirements.


  • Access to a domain whose DNS records you can configure.
  • A Linux server (we'll use Ubuntu) whose host allows it to send mail, which primarily means that outgoing port 25 should be open.
  • Know-how to set up a secure server before we install Ptorx onto it.
  • Nginx or similar software installed to serve static files and act as a proxy for Ptorx and other APIs.
  • Let's Encrypt or similar geniune TLS (SSL) certificate (no self-signed certs!) for your main domain where the instance of Ptorx will be hosted. Additional mail-only domains don't need this.
  • Node.js installed on your server. Ptorx targets the latest version available at time of the last server/package.json update.
  • MariaDB or MySQL installed on your server (no STRICT_TRANS_TABLES!). runs MariaDB so there may be unknown discrepancies with MySQL.
  • sendmail installed on your server. (Make sure your server's hostname is set correctly to prevent slow mail!)
  • iptables-persistent installed on your server.

Step 0: Clone the Repo

First change to the directory where you wish to keep Ptorx.

git clone --recurse-submodules
cd ptorx

From now on we'll assume commands are run from ptorx/.

Step 1: Download npm Dependencies

Install npm depencies for each module:

cd server
npm install
cd ../web
npm install
cd ../accownt/server
npm install
cd ../web
npm install
cd ../../ccashcow/server
npm install
cd ../web
npm install
cd ../../yalcs/loader
npm install
cd ../server
npm install
cd ../web
npm install
cd ../../ # back to ptorx/

Then install pm2 to manage our API servers:

npm install -g pm2

Technically pm2 is not required, but it's what we'll use for this tutorial.

Step 2: Create Database

Create a database and preferably a non-root MySQL user with SELECT, INSERT, UPDATE, and DELETE privileges as well. We'll name our database ptorx but any name will do.

sudo mysql -u root -e "CREATE DATABASE ptorx"

Next we'll build the database:

sudo mysql -u root -p ptorx < server/db/build/structure.sql
sudo mysql -u root -p ptorx < server/db/build/data.sql

Replace ptorx with the name of your database.

Step 3: Create Data Directories

Now we need to create the data directories where Ptorx and its submodules will write both temporary and permanent data to the disk. You can put them wherever you'd like (just remember it for Step 4), but for now we'll put them alongside ptorx/.

mkdir ../accownt-db ../mail-cache ../ccashcow-db ../yalcs-db

You can also name the three directories however you'd like.

Step 4: Set Environment Variables

Ptorx and its submodules are configured via environment variables which are loaded into the applications via .env files located in each modules's directory.

To understand the syntax of the .env files, know that they are first loaded via dotenv and then the string values provided by dotenv are parsed by enve.

Step 4a: Create .env Files

First we'll create each file and then we'll work our way through populating them with values.

touch accownt/server/.env accownt/web/.env ccashcow/server/.env ccashcow/web/.env
cp server/example.env server/.env
cp web/example.env web/.env

Step 4b: Configure CCashCow

See Xyfir/ccashcow for instructions.

Use vim or nano or similar to edit the files ccashcow/server/.env and ccashcow/web/.env.

Step 4c: Configure Accownt

See Xyfir/accownt for instructions.

Edit the files accownt/server/.env and accownt/web/.env.

Step 4d: Configure Yalcs

See Xyfir/yalcs for instructions.

Edit the files yalcs/loader/.env, yalcs/server/.env, and yalcs/web/.env.

Step 4e: Configure Ptorx

Now we'll do the same thing for Ptorx. You can find the available environment variables in types/ptorx.d.ts under the Ptorx.Env namespace.

Step 5: Build From Source

cd server
npm run build
cd ../web
npm run build
cd ../accownt/server
npm run build
cd ../web
npm run build
cd ../../ccashcow/server
npm run build
cd ../web
npm run build
cd ../../yalcs/loader
npm run build
cd ../server
npm run build
cd ../web
npm run build
cd ../../

Step 6: Open and Forward Ports

Make sure your firewall allows traffic through the needed ports. If you're using ufw, it'll look something like:

sudo ufw allow smtp # 25
sudo ufw allow submission # 587
sudo ufw allow 2071 # -> 25
sudo ufw allow 2076 # -> 587

Next we'll need to forward incoming traffic from port 25 to the port you set for the MTA server via MTA_PORT in server/.env. We'll also forward 587 to the port for the MSA server, as configured via MSA_PORT. We'll assume the suggested ports for each.

sudo iptables -t nat -A PREROUTING -p tcp --dport 25 -j REDIRECT --to-port 2071
sudo iptables -t nat -A PREROUTING -p tcp --dport 587 -j REDIRECT --to-port 2076
sudo iptables -t nat -nvL # optionally validate your rules
iptables-save > /etc/iptables/rules.v4

Suggested Ports

Ptorx requires a lot of servers. The suggested local ports are as follows:

Name Port
Ptorx API 2070
Ptorx MTA 2071
Ptorx test MTA 2072
Ptorx client (for dev) 2073
Accownt 2074
CCashCow 2075
Ptorx MSA 2076
Yalcs 2079

Step 7: Set DNS Records

For this step, we'll be using as a placeholder for your domain.

Step 7a: DKIM

First of all, set the domain key TXT record to <SELECTOR> as provided by the Ptorx app after you've added your domain. Ignore the other records it tells you to set.

Step 7b: MX

Create a single MX record for that points to your server's IP address, which will probably be the same as your domain's A record. The priority doesn't matter with only a single server, but we'll set it to 10.

Step 7c: SPF

This step is optional but highly recommended to prevent your mail from being marked as spam.

Create a TXT record for with something like this:

"v=spf1 +a ~all"

Before you blindly copy and paste, you should understand how SPF works and how best to utilize it according your needs.

Step 7d: DMARC

This step is optional but highly recommended to prevent your mail from being marked as spam.

Create a TXT record for with something like this:

"v=DMARC1; p=reject; fo=1;;"

Before you blindly copy and paste, you should understand how DMARC works and how best to utilize it according your needs.

Step 7e: Reverse DNS

This step is optional but highly recommended to prevent your mail from being marked as spam.

Go to your server host's control panel and change the reverse DNS to your domain name. By default its value probably looks something like where is your server's IPv4 address and is the name of your server host. For example with VULTR, which Ptorx uses, it'll look like, and it can be found under the Settings > IPv4 tab when viewing your server instance.

Step 8: Start Servers

Last but not least, start the servers with pm2, which you should have installed earlier:

cd server
pm2 start --name ptorx npm -- run start
cd ../accownt/server
pm2 start --name accownt npm -- run start
cd ../../ccashcow/server
pm2 start --name ccashcow npm -- run start
cd ../../yalcs/server
pm2 start --name yalcs npm -- run start
cd ../../
pm2 startup # then follow instructions

Upgrading Ptorx

This is a general guide for upgrading from one version of Ptorx to another. It's likely there are more specific steps you'll have to follow based on your current version and that of which you wish to upgrade to, but these steps should typically get you at least 90% of the way there.

To begin the process of upgrading Ptorx, let's first reset the repos and pull in changes:

git reset --hard origin/master
git submodule foreach git reset --hard
git pull
git submodule update --recursive

Now we'll once again run through some of the steps above:

  • Go to Step 1 to update dependencies.
  • Go to Step 4 to update any .env files that may require changes.
  • Go to Step 5 to rebuild the apps.

Update your database if needed by running in order the server/db/upgrade/ SQL files for every version after your current installation's. For example, assuming you're on version 1.0.0 and the latest is 1.1.0:

sudo mysql -u root -p ptorx < server/db/upgrade/1.0.1.sql
sudo mysql -u root -p ptorx < server/db/upgrade/1.0.2.sql
sudo mysql -u root -p ptorx < server/db/upgrade/1.1.0.sql

Be sure to replace ptorx with the actual name of your database.

Finally, restart the servers:

pm2 restart all
