Your logs say:

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

Hi,
I'm running a Postfix+Cyrus+Ldap Auth mail (IMAP) server on a Suse 9.1 with about 200 users.
The software versions are:
cyrus-imapd-2.2.3-83.22
postfix-2.1.1-1.20

It's working fine since 2005, but now i'm facing a strange problem on a user mailbox. An email is received by the MTA, then postfix delivers this email to CyrusImap with /usr/lib/cyrus/bin/deliver.
From the /var/log/messages i see:

May 31 20:37:37 server lmtpunix[31094]: accepted connection
May 31 20:37:37 server lmtpunix[31094]: lmtp connection preauth'd as postman
May 31 20:37:37 server lmtpunix[31094]: duplicate_check: <86D6BCB7F53B8D46980FE134992AA0020395DB3A@xxxxxxxxxxxxxx> user.beppe 0

May 31 20:37:37 server lmtpunix[31094]: mystore: starting txn 2147483677

May 31 20:37:37 server lmtpunix[31094]: mystore: starting txn 2147483678
May 31 20:37:37 server lmtpunix[31094]: mystore: committing txn 2147483678
May 31 20:37:37 server lmtpunix[31094]: duplicate_mark: <86D6BCB7F53B8D46980FE134992AA0020395DB3A@AMAILSERVER,it> .beppe+@.sieve. 1180636657 0

So it seems that the message was correctly delivered, and in fact in the user FS folder there is a file containing the email! But this email doesn't appear via IMAP, and the only way to make it visible was:

reconstruct -f user/beppe

It isn't the first time that i've this strange behaviour, and since today i saw this issue only on a single user folder.
Any ideas?

Thanks
G.Ravasio
