Greylisting in action message?

[CrustyDOD]

Just got this problem. If i send email to him or he to me, in the logs it says this:

2007-05-23 17:33:39 1HqsqJ-0000mT-OI <= MY_EMAIL H=MY_IP ([192.168.2.105]) [MY_IP] P=esmtpa A=plain:MY_EMAIL S=729 id=46545A40.5090400@MY_SERVER_DOMAIN_NAME T="test" from <MY_EMAIL> for RECEIPT_EMAIL
2007-05-23 17:33:39 1HqsqJ-0000mT-OI SMTP error from remote mail server after RCPT TO:<RECEIPT_EMAIL>: host mail.HIS_DOMAIN [HIS_IP]: 451 4.7.1 Greylisting in action, please come back in 00:01:00

2007-05-23 17:33:42 1HqsqJ-0000mT-OI Completed

Any ideas what is going on? Is the problem on my side or his? I can't find anything on my server anything about greylisting so i'm guessing he has it and it doing this? Funny thing, other emails on his server seem to work just fine if i send email to them from the same email as to him.

From what you've posted (hard to tell because you munged IP#s and domain names):

His server is running greylisting. Your server is trying to verify his address before accepting email, and running into his greylisting. You're running into the greylisting when you try to send him email.

If he's running greylisting properly, then email to him should eventually get to him, probably within less than a few minutes.

And email from him to you should also get to him.

DirectAdmin doesn't use greylisting unless you've made changes.

Ah ok, so basically the problem is on his side. No, i made no change to DA. Emails do go forward but sometimes it takes even up to 24 hours :S

I'll contact him and tell him that he needs to fix it.

Thanks jlasman for help

As I wrote, it was hard to determine what you wanted to do.

Is it mails to him that are delayed? If so your /var/log/exim/mainlog may show why.
