Ghost emails

[Florian Gleixner]

Your logs say:

May 31 20:37:37 server lmtpunix[31094]: duplicate_mark:
<86D6BCB7F53B8D46980FE134992AA0020395DB3A at AMAILSERVER,it> .beppe+ at .sieve.

this means, that cyrus thinks this message is a duplicate of a existing 
mail in the users mailbox. Some broken email clients may generate 
non-unique Message-Ids (groupwise has this bug in one version, some 
outlook versions, ...). Search your mail logs (/var/log/mail) whether 
you see the Id 86D6BCB7F53B8D46980FE134992AA0020395DB3A at AMAILSERVER,it 
for different incoming mails.
If you see this the only way to get the mails is to unset 
"duplicatesuppression" in cyrus - or to fix broken mail clients.
