We've also had problems with incoming messages from mailing lists generated by Mailman etc. The logs of the sending server show them being delivered to our ES 5.5 server, and message tracking indicates that they have been delivered to the correct mailboxes. They then appear in some mailboxes correctly, but not in others. I've tried using the Exchange Client to search for the message with no result.
We've also had situations where a message (either from within or outside our organisation) is sent to multiple outside mailing lists on multiple outside servers. If one of our users is on more than one of these lists then they receive only one copy of the message - it's as if some form of de-duplication is taking place somewhere..... By the way, this latter behaviour also seems to occur in other related organisations who are on the same mailing lists. They all use ES (various versions) as far as I am aware.

When a message is sent to this list, there are 240 members, there always seem to be a number of failures, which appear to be random. Any ideas why? I have looked for events in the logs after switching on all logging for mta, is, transport etc, but nothing useful. They are not over their mailbox limit, they do not all have inbox rules, so I am baffled.
