But did you check that all programs writing to mailboxes use the same locking? Most importantly procmail vs. dovecot might not use the exact same locking by default. http://wiki.dovecot.org/MboxLocking signature.asc Description: This is a digitally signed message part
[Dovecot] Dovecot truncating Inboxes?
Hi, Environment: 1 Users (LDAP) Solaris 10 / sparc imap: dovecot-1.1.10 (pam-unix, no direct LDAP access) pop: dovecot-1.0.14 on another server (pam-unix, no direct LDAP access) mta: postfix (pam-unix, no direct LDAP access) procmail (pam-unix, no direct LDAP access) Filesystems: Inboxes and IMAP-home are on two different SAM-FS volumes. Problem description: Inboxes of users are disappearing / are truncated. we are using dovecot-1.1.0 since two month as main IMAP server. It replaced our long running but old version of UW-IMAP. Till the last week we had no problems and it worked quite well and the whole mail system worked in this configuration since several years. But since a week we receive more and more complaints regarding truncated/deleted mailboxes. First, we assumed user/client errors, but as such messages arrive more frequently, we did a deep analysis of the issue. The only common component of our mail system (postfix (local), procmail, pop, imap) that all concerned users have accessed, was dovecot-imap v. 1.1.10. We have no locking problems, we use fcntl(), dotlock for all mail components. We tested this with a small perl script and locking works fine (no delivery to a locked mailbox and so on...) Finally, all indications point to a bug in dovecot. Google and searches in this mailing list did not come up with any valuable results. Are there any known bugs / configuration problems concerned to the described problem? I greatly appreciate any help! Thx in advance Harald Strack

It These are all very very old. These versions certainly have bugs, perhaps also one which you stumbled on. I suggest you upgrade to 1.1.20 or, better, to 1.2.8 (some configuration changes may be needed). If the problem remains afterwards, there might be people willing to help. HTH, Jakob Curdes
