Message disappears between MTA and mailbox server

[phoenix]

I just ran across this, and it turned out to be a filter setup on the receiving users' mailbox. Simple solution, but more explicit log messages in a more commonly viewed log would be appreciated.

Check bugzilla for any filed bugs or RFEs (Enhancements), if you don't find any then please file an RFE.

I ran across the same issue, the mail was not delevered for duplicate message-id:

mailbox.log.2010-06-23:2010-06-23 17:53:37,771 INFO  [LmtpServer-24482] [ip=192.168.30.5;] lmtp - Delivering message: size=34582 bytes, nrcpts=3, sender=user@domain.com, msgid=<!&!AAAAAAAAAAAYAAAAAAAAAJaD01H6XMxKoM5eYzemjADCgAAAEAAAAMCEUv/eYNxJkBjeGH+FkW8BAAAAAA==@domain.com>

there is another message of 16-06-2010 with the same message-id, but it's a different message:

mailbox.log.2010-06-16:2010-06-16 18:49:30,411 INFO  [LmtpServer-20651] [name=e444825@domain.it;mid=12;ip=192.168.30.5;] mailop - Adding Message: id=52815, Message-ID=<!&!AAAAAAAAAAAYAAAAAAAAAJaD01H6XMxKoM5eYzemjADCgAAAEAAAAMCEUv/eYNxJkBjeGH+FkW8BAAAAAA==@domain.com>, parentId=-1, folderId=2, folderName=Inbox.

domain.com and domain.it are placeholders

I wonder how can be there 2 messages with the same massage-id, whene they are totally different?
Aren't message-id a random string such that proabability of 2 collapse message-is is very very far?
Is this a zimbra bug?
