Virtual hosts

Let's say you want to host domains first.com and second.com.
Create folders for their files:

  
## index.php
<?php
/*
This is a very tiny proof-of-concept SMTP client. Currently it's over 320 characters (if the var names are compressed). Think you can build one smaller?
*/

ini_set('default_socket_timeout', 3);

$user = 'you@gmail.com';
$pass = '';
$host = 'ssl://smtp.gmail.com';

cd ~/mailcow-dockerized

                Rsync over SSH - (40MB/s over 1GB NICs)
              
          
    The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync
(Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs
