Frank Astin asked:
I’ve set up a mail server according to this guide.
When I telnet mydomain.com 25 and use the AUTH command it returns:
Error: authentication not enabled
Trying to login via outlook returns an unknown error and when I send an e-mail to an adress I get an relay access denied error.
mxtoolbox tells me everything is set up ok.
You’re using the wrong port.
Authenticated outgoing email is on port 587, not port 25.
