Mailtrain 2 - Configure Generic SMTP

Log into the trusted site of your mailtrain service (e.g. not the public or sandbox domains).

Select Administration from the navbar, before selecting Send Configurations

Click the button in the top right to Create Send Configuration

Fill in the details of your SMTP server and click save.

If you have a Gmail email address, you can easily configure Gmail as your SMTP provider. I explain how to do so in my post about configuring Seafile to send through Gmail.
