Since I did an update today, while other prividers are working, I can´t receive any mail from my mailcow-dockerized server on gmail anymore. The mails howerver aren´t being rejected. I get status 250 from the google server in my logs.

Any ideas anyone?

Have something to say?

esackbauer then can you please link a post discussing (and hopefully solving) this issue here?

esackbauer Yep, no warnings whatsoever.
Only Gmail isn’t working.

      you should check your TLSA record if you have one. Are the mails still in your mailcow queue?

        Wouldn’t my client then also report an invalid certificate? I had problems with the acme container in the past - it wouldn’t renew them correctly - I then manually ln'ed them after using certonly - after this it was working.
        The last renew (after which it worked) was not even a month ago.

        @“esackbauer”

        At least this testing website says, the certs are ok

          Then I have no clue what it could be. I am also on 2024-01a now, and I can still send to my Gmail test accounts without problem, but I have a Sophos Firewall acting als MTA inbetween mailcow and the internet.
