I totally can't get domainkeys to work: I've got an account blah.com set up on its own unique IP, reverse DNS works correctly, SPF is fine too. I've enabled domain keys using that domain's cPanel setting, and something which looks correct does appear on the DNS (see below) but ALL tests fail. I've tried the one at DomainKeys test, DomainKey Policy Record Tester (says "No _domainkey TXT record found for domain.com"), firstname.lastname@example.org and they all fail.
The only one that yields anything is the selector record tester from DomainKey Selector Record Tester, which says "This selector appears valid"
Should exim be adding extra headers to email it sends out that contain DomainKeys info? I'm not seeing anything if that's the case.
DNS entries made by cPanel:
Record type: TXT
I tried restarting named AND exim after these changes and nothing seemed to help... I'd REALLY appreciate any help on this, I've been banging my head against the wall for ages now and our emails keep getting put in the spam bin.
