Greylisting problem

Post by wkuypers »

I don't know if the problem is on your site, but I just like to mention it. We are having problems with the greylisting filter. The email that I gave here under, the server tried just 2x times, and then the server gave up (in stead of retrying). I have also had the case with hotmail.com (even if the problem only appeared from time to time).

This is what the server mentionned in the undelivry report :
There was a SMTP communication problem with the recipient's email
server. Please contact your system administrator.
<hpsmtp-eml18.kpnxchange.com #5.5.0 smtp;550 Recipient not in route list.>

this was twice in the rollernet log (for mail. and mail2. but no retry0
Connection from 213.75.38.118 (hpsmtp-eml18.kpnxchange.com) deferred by mail.rollernet.us

Looks like the server just won't retry. I've also seen this recently with Charter Cable mail servers where they incorrectly treat a 4xx defer as a 5xx reject. Aside from trying to convince the operator they're running a broken mail server, all you can do it whitelist the trouble addresses from the greylist filter, if desired.

What does this mean "Recipient not in route list." (it's in the first message) ?
Is it a routing problem ?

No idea - it's not an error message from us. Sounds like an unknown user error to me though.
