What settings need to be changed in "main.cf"? Authentication-Results: domainkeys=softfail, dkim=softfail I'm noticing that a lot of spam getting through has softfails in the Authentication Results in the header. Is it possible to have this mail rejected? Also, what does "SPAM dsn cutoff level" mean? Wish there was a tooltip actually explaining this settings. Have been looking online all over just to figure this out.
All settings are explained in detail in the ispconfig manual. This setting is e.g. explained on page 173. A tooltip help extension for ispconfig will be available soon as well.
OK now I did not find any way of having dkim=softfail be rejected though. What needs to be edited in main.cf for these e-mails to be bounced?
I think that postfix not it self is able to do that. but maybe you can reject it so you can check out .
