Hi there,
I’ve followed the setup guide and cannot seem to get mailcow to work on my DigitalOcean VPS. I cannot send or receive email.
My domain is: ghent.cloud with mail pointed to mail.ghent.cloud
I am running Mailcow behind the jwilder/nginx-proxy (which doesn’t appear to be the issue as I can connect to the UI fine)
I have a couple of errors that seem to be causing issues:
I get the following error from Postfix when sending an email outbound (i’ve tried with many different domains)
to=<redacted@gmail.com>, relay=none, delay=84687, delays=84677/0.27/10/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=gmail.com type=MX: Host not found, try again)
And I get the following from dovecot on boot
doveconf: Error: t_readlink(/var/run/dovecot/dovecot.conf) failed: readlink() failed: No such file or directory
Warning: Transient problem: timeout Will retry in 1 seconds. 10 retries left.
However I can successfully ping from the unbound container
docker exec -it mailcowdockerized_unbound-mailcow_1 bash ping maps.rspamd.com
PING maps.rspamd.com (88.99.142.95): 56 data bytes 64 bytes from 88.99.142.95: seq=0 ttl=55 time=18.852 ms 64 bytes from 88.99.142.95: seq=1 ttl=55 time=18.093 ms
Additionally, when running the DNS check in the mailcow admin, it returns a 502 gateway for the domain.
I hope that this is enough information to help debug. Please let me know if you have any advice. Thanks for reading
Below is my docker-compose - slightly modified with a VIRTUAL_HOST that the nginx-proxy requires.
