Simple WordPress plugin to set the "envelope sender" correctly, so that e.g. Gmail accepts them. Just create a folder "wp-content/plugins/fix-mail-sender" and put this file there. Don't forget to activate the plugin and enjoy. Note: if you are on Hetzner, you need to create a mailbox "wordpress@yourdomain.tld" too to make it work. Don't ask why.

How to install iTunes 12 on Linux Mint 18 with working Store
Trying to run iTunes with Wine, i faced various problems. Here is a working solution how to install iTunes on Debian-based systems (in my case Linux Mint 18.1) - with support for the iTunes Store. Warning: Syncing i-devices is still not possible.
When installing it with the playonlinux-"iTunes 12"-script, log in into the Store was not possible in my case. Wine showed the follwing error when trying to log in: SecurityContext failed with error 0x80090304
1. Install current Wine version (2.0.1) directly from the winehq repository
wget -nc https://dl.winehq.org/wine-builds/Release.key
sudo apt-key add Release.key
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main'
sudo apt-get update
sudo apt-get install --install-recommends winehq-stable
wine --version
