Spamassassin ClamAV Amavis Greylisting etc

[ekeis98]

Found out that Maia Mailguard (http://www.maiamailguard.com/) seem to be my solution. I'll check it out...

So, actually my server seems to run fine. But i got some annoying prob. My server, not really my server, but one email account on my server, will continuously not accept any emails from a certain domain and i dont know where start tracking this misconfiguration.

The situation:
EmailA and EmailB are accounts on my server. EmailX is the account with is accepted by EmailA, but not accepted by EmailB.
* Sending EmailX to EmailA can be watched with 'tail -f /var/log/mail.info'. You can see that it is first greylisted and after that accepted (I'm still wondering why it is greylisted everytime. I thought that emailaddress would be put in some kind of whitelist after it was sent for the first time and accepted...anyway.)
* Sending EmailX to EmailB cant be watched nowhere. You dont see any reaction in any logfile.

Where can i look for my misconfiguration?

Any help really appreciated.

Thanks in advance.

Oliver.
