After years of running manually-configured mail server stacks I’ve now decided to jump into the world of Mailcow for the first time, and really enjoying it so far!
The new system is up and running now and already configured to my liking for the most part, but I’m having a small issue for which there’s probably an obvious solution, but which I just can’t seem to figure out.
Basically, I’m trying to add a certain DNS blacklist to Mailcow and would also like to see which bls are currently configured.
I’ve been trying to find documentation on how to do this but haven’t been able to, and to complicate things further I’m not sure if Mailcow uses postscreen or Rspamd for checking senders’ IPs against those blacklists.
If someone here could kindly point me in the right direction that would be greatly appreciated, many thanks!
