This would appear to be a bug in Exchange.

Greylisting is active at the recipient's mail server.  What is happening is that their mail server is sending your mail server a message which says "Sorry, can't accept your message right now as you may be a spammer, however, if you email me the same message again in 4 minutes, then there's a pretty good chance that you are not a spammer, and I will accept your message then."

Exchange doesn't seem to understand this response.  I have done a search on this topic, and there seem to be a lot of other people with this problem, but no apparent solution.  If anyone knows how to resolve this, it will be Sembee.

Have you looked in your Mail Server logs to verify what I am saying.  Can you post some anonymised examples?

To elaborate on my last post, what happens if you send the message five minutes later (from the same domain, the same email address, the same IP address)?  Does it then go through?  (The mail logs will tell you that).  If it does go through, then the solution is as follows:-

(1) Get users to send two identical messages to recipients that are known to have persistent grey-listing enabled (I tend to configure mail-servers to remember senders that pass the grey-listing test for a very long period after a successful send).  In the second message, delay the sending by an arbitrary number of minutes.  See this:-


This is, of course, a workaround, so there's a (2):-

(2) Send the mail server logs, both of them - the one showing grey-listing, and the other showing success - to Microsoft, asking if there is a bug-fix.

(3) If there is no satisfactory outcome from Microsoft and your are not prepared to accept any workaround, then perhaps it is time to look at other products on the market.  My own experiences with grey-listing is that it is very effective, if other mail server administrators achieve the same findings then this problem will get worse for administrators of systems that do not recognise the grey-list response.

I tend to configure...

Sorry, didn't hammer the point home: By mail-servers remembering bona fide senders for long periods, you will only have to very infrequently need to send two messages to unblock successful receipt.  But some admins may choose to remember bona fide senders for this session only, which is counter-productive.
