Im actually testing signing outgoing mails with domainkeys, but have some trouble.
I configured the DKIM features like in the E-learning module described.
I also inserted the RSA key in TXT section of the DNS-server.
If I send a mail to yahoo, it is recognized as SPAM and seems to have no valid DKIM signature.
here you see a part of the Ironport mail-log:
Dec 17 09:56:20 antispam-iat mail_logs: Info: MID 32848 DomainKeys: cannot sign - no profile matches [email protected]
Dec 17 09:56:20 antispam-iat mail_logs: Info: MID 32848 DKIM: signing with MyProfile1 - matches [email protected]
Where is the fault ?
