Set up your own mail server with Mailcow

[dadirkes]

Problem

Ports 25 and 465 are blocked on Hetzner vhosts and it seems that mailcow is not able to send via STARTTLS port 587 by default.

Suggested Fix

You can find a hint in the prerequisites of the tutorial:

Hetzner Cloud servers by default block port 25 and 465 to protect from spammers. You can request to get the ports unblocked after your first invoice was paid. This basically acts as a simple verification, that you are not a spammer.
