How are people sending emails from their self hosted apps? I Thought MailSender would be good but i guess not. Im about to try SendPulse now. Why isnt there a service that doesnt care what you do with your emails as long as you only sending max a few emails a day?

.test internal domain, own postfix SMTP+dovecot IMAP server.

The IMAP server is accessible from WAN via IMAPS (HAproxy+SSL/letsencrypt certificate).

As per securing against brute force attacks:

  • Dovecot has a listener process configured to talk the HAproxy's specific PROXY protocol which passes the original client IP to Dovecot, so the latter can apply its own authentication penalty algorithm

  • Crowdsec is installed with the HAproxy plugin, so client IPs can also be banned after authentication errors, albeit I'm not sure this works with HAproxy's PROXY protocol
