Hello, I recently saw these errors in my log, and one of my users complained that Dovecot disconnected him unexpectedly. Any idea what might have happened? dovecot: Error: IMAP(bmoore at forkit.org): file maildir-sync.c: line 1075 (maildir_sync_index): assertion failed: (uid > prev_uid) dovecot: Error: IMAP(bmoore at forkit.org): Raw backtrace: /usr/local/libexec/dovecot/imap [0x80b6501] -> /usr/local/libexec/dovecot/imap [0x80b641c] -> /usr/local/libexec/dovecot/imap(maildir_sync_index+0x902) [0x8069042] -> /usr/local/libexec/dovecot/imap [0x8069243] ->...

...ixes this by sorting the messages: First the POP3 messages get their new UIDs in order of their appearance in courierpop3dsizelist (so that the UIDL order will really be the same as in Courier), after that, the IMAP-only messages will be checked for UID clashes. The patch also changes how the $prev_uid variable is handled because that was also needed to always get the order right. The algorithm could probably be optimized to reduce the number of UID re-assignments to a minimum, however this would complicate the code and would only be noticed in a few cases. The patched courier-dovecot-migrat...
