I have 2 NIC's with 2 different ISP's (so 2 different IP's). Let's call ISP 1 "WAN 1" and ISP 2 "WAN 2". I'm not allowed ( I can't send or receive) to use a mailserver on WAN 1, so I can only use WAN 2 to send and receive mail. I've enabled Uplink balancing set WAN 1 as first and WAN 2 as second and auto monitoring. Then I made a Multipath Rule: Any->SMTP->Any (by Interface)-> WAN 2.
Then I used the DKIM how to from the Knowledge base and followed all the steps and tests and that worked fine. I have 3 domains which I use. On all zones of the domains I copied the public key, so this should not be a problem.
I can send and receive mail. But when I send to my account at Yahoo.com (which supports Domain Keys) it shows the following:
From Me Wed Apr 8 20:45:36 2009
Return-Path:
Authentication-Results: mta170.mail.re4.yahoo.com from=mydomain.com; domainkeys=neutral (no sig); from=; dkim=temperror(d2i_PUBKEY_bio() failed)

Also when I send a test e-mail to sa-test@sendmail.net and get the following error:
Authentication System: DomainKeys Identified Mail
Result: DKIM signature confirmed BAD
Description: Unrecoverable error during processing; signature data cannot be verified
Reporting host: sendmail.net
More information: Domain Keys Identified Mail (DKIM)
Sendmail milter: https://sourceforge.net/projects/dkim-milter/
Does anyone know where this problem is caused, so in Astaro or on my DNS server?
