The sole use of this server will be to filter who my son can sent emails.
So his client connects to my smtp the To: address is validated and then the email will be relayed to Zen,
trouble is its not working
I get the following back from the zen email servers
Jun 7 16:19:26 hostname postfix/smtp: 918BB141AB5: to=<me@mydomain>, relay=mailhost.zen.co.uk[22.214.171.124]:25, delay=0.26, delays=0.14/0.01/0.07/0.05, dsn=2.0.0, status=sent (250 OK id=1Z1cLs-0000ce-TY)
From my understanding dsn=2.0.0 means the upstream server has accepted the email, but the email does not arrive and there is no bounce back,
Do Zen actively block email relays ?
