Hi all,
I’m setting up a new mailcow.
I added a single domain with multiple mailboxes. I then added a number of domain aliases, all pointing to this single domain.
I’ve configured the A and AAAA records in the main domain, but didn’t change the MX record on that one just yet as I wanted to try this out with one of my aliases first.
I configured the alias according to the settings that are shown in the UI, and I can receive emails from most providers on that alias, including from Outlook. I’ve received emails from 3rd party services and so on.
But I can’t receive emails from GMail. I tried sending with my personal GMail account to one of my domain aliases, and it just doesn’t work.
What’s weirdest is that I don’t even see GMail attempting to connect to my Postfix in the logs 🙁 so pretty hard to figure out what’s going wrong.
I’ve gone as far as deleting and re-adding the MX record on the alias just to work out whether that had gone wrong, but no luck…
Any ideas what could be going wrong here? Any help is much much appreciated as I now ran out of places where to look 🙁
Thanks!
Tiago
