Can send emails but not receive

TxJn

Hello Mailcow Community,

Just finished deploying mailcow via following a couple of online guides/referencing the official doco. Mail-Test.com score of 7.2, can send emails to external address no issues (not getting flagged as SPAM) but I cannot receive…

Have setup all DNS records as directed, opened ports on UFW, etc, but still can’t figure it out.

Can someone point me in the right direction please?

TxJn

Update: After doing some more reading I tried port forwarding port 25 in my router to the IP of my mail server and that appears to have got it working.

Have I done something wrong? Is port 25 unsecured?

(Ports 465 and 587 were already forwarded)

Port 25 is for server to server communitication and needed for using a mailserver. The other ports mentioned are for client to server
