@feld @delta that would be a great improvement DNS server records for which ports are which protocol #dns #smtp #linux

@delta One thing I don't understand: how can you send email when you don't store it for long. This means messages are only stored in the client yes, but it shortly stored by the server until it's collected by the client?

@delta Thank you for explaining!
I already have a mailserver at home so on ipv4 SMTP ports are taken. I can set up an ipv6 server. Is there a way, perhaps with dns, to let other servers / clients know to use other ports if they only speak ipv4?
