I have seen this before and found it to be the version of the routing
engine dll files. If the SP3 is installed without the post SP3 hotfix
April edition then you may see this occur. This has mainly occurred with
the MTAroute dll since when a mail comes from 5.5 it uses the MTA to
lookup the address. In E2K the route is looked up as the mail leaves the
outbox, which is why sometimes you see it being delayed there. However,
with a message that originates from 5.5 then the route is looked up on
each hop. This is where the MTAroute.dll file comes into play. Once the
message has been through the categorizer and so drops into the post
categorization phase it takes one of two paths. If it originates from
5.5 then it will go via the MTAroute.dll if its a 2000 / 2003 then it
will utilise the REAPI.dll and be assigned delivery either to local or
remote queue. The chances are this is where you may be experiencing your
You may also look through ESM and see some of these messages stuck in
the waiting to be routed queue. 
Hope this helps.

We have had this happen once or twice and I'd like to get an idea what
causes the problem. One of my users complained of not receiving an
email. When we track the message it has failed on the advanced queue.
Could somebody shed some light on this? We are running exchange 2003
standard on Windows 2000 Server with all patches and SPs.
