I've actually just changed the mail delivery settings to the follwing in the hope that it will be delivered to hosts with greylisting in place. I am unsure what the best settings would be so chose a wider retry range.
I guess it's a trade-off between the allowed retry in the greylisting software, the amount of time the greylisting software remembers an initial connection attempt, and mail performance. Any guidance would be much appreciated. New mail delivery settings First retry interval: 10 Second Retry interval: 60 Third retry interval: 120 Subsequent retry interval: 220 Anyone clarify the issue that Ex2003 has with greylisting 4xx replies and any workarounds? I'm investigating that now -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Hutchings Sent: 26 November 2007 10:53 To: Exchange Discussions Subject: RE: Unexpected outgoing mail delay Damned if I remember where, but I read about a problem with Exchange 2003 not being able to properly deal with the 4xx replies from Graylisting software, I don't remember all the details but your problem rings a bell as being very similar.

MS Exchange 2003 SP2. MS Outlook XP/2003. I rebooted an Exchange server at 16:16 21st November and a number of people contacted me saying that external mail they sent on the 7th November was either only just delivered or they only just received and NDR! I have used message tracking to confirm this. I don't understand why the mail didn't time out as per my settings or the user was not notified of the delay. I don't remember seeing any of this mail in a queue either, where has it been? My settings - First retry interval: 10 Second Retry interval: 10 Third retry interval: 10 Subsequent retry interval: 20 Delay notification: 6 hours Expiration timeout: 3 days Message tracking for one of the delayed messages -
