I have mailcow server for a few months now and it was working fine.
However, when I’ve added/ changes a few things, wordpress stopped sending emails to the server for some reason.
1: I added cloudflare to my main domain.
2: I’ve added the TLSA in cloudflare and it now has a green icon inside mailcow.
3: I’ve changed the rspamd filter values to: 7 - 11 - 15,,,, Now 4-7-15
But no luck, sending emails from wordfence is not working, and sending emails from normal email app or inbox works fine.
I have enforce tls for both incoming and outgoing but it was sending stuff normally.
The emails doesn’t even get to rspamd, so I think this is not rspamd problem.
I would love if someone can help me out because I’m kinda lost and its been a few weeks like this and I’m not sure what to do.
I will provide any details or anything to help solve the problem.
The main domain have HSTS and DNSSEC enabled.
Mailcow server is : mail.mydomain.com
Thanks for advance.
