We use SMTP to send your emails.
This enables virtually anyone to connect to their self-hosted email (e.g. from the hosting provider).
For Gmail users a SMTP / IMAP password must be created separately. (More info in the specially created post)
It is also possible to specify the SMTP data of one email, and connect the IMAP account to another.
Send emails via email@example.com
and the mailboxes from firstname.lastname@example.org
It is also possible to use SMTP credentials from mail providers like Amazon SES.
