Three years ago I blogged about Using Mailhog as my default MTA and that worked great for me. However, Mailhog development seems to be stalled and it had occasional problems with some perfectly fine mails. So when I stumbled across Mailpit, it was time to switch.

The setup is basically the same.

Install via AUR:

yay -Sy mailpit-bin

Adjust the systemd service file using `systemctl edit mailpit.service` and use the following:

[Service]
Environment="MP_SMTP_BIND_ADDR=0.0.0.0:25"
Environment="MP_UI_BIND_ADDR=0.0.0.0:8026"
User=root

Enable the service

systemctl enable mailpit
systemctl start mailpit

Configure PHP to use it's mailpit's delivery agent:

/etc/php/conf.d/mailpit.ini

sendmail_path = "/usr/bin/mailpit sendmail -S=localhost:25"
