You control both of the two servers with which you're testing, right? You probably generated the server certs being used with both servers, using an openSSL or mod_ssl test program/script, right?
My guess is that both servers have certs with the same exact issuer name and serial number, but different public keys. That's invalid. (Am I right?)
Duh, idiot. Seems to be the problem with my test case. I was just trying to recreate a problem someone else is having, he's using another server that i dont have access to. I'll get him to check the issuers, and also get the slack sysops to fix the mail server. Groan, what a waste of time!
Thanks a lot anyway, i knew it had to be something simple.
