Hi everyone.
Sorry for the maybe very open question.
I have a working setup, but working is boring right ;-)
And I would love to get rid of some spam, what is my best way forward?
I will paste postconf below and besides that I have a rspamd running
that handles signing and also rejects some spam for me...
On my older mailserver (windows / Mercury) I used a long list og dnsbl,
but I have read somewhere that I should avoid that due to performance.
And I'm not sure it worked better than what I have now.
I have a small setup only handling a few hundred mails per day.
Do you need any more info from me?
All the best from Denmark!
Danjel
