It really isn't, though. Worse, without the -R flag, I think it is, reconstruct will touch all the message files, changing their date to the time reconstruct was run. Not really nice.

Unfortunately, it's happened again. That same user is now unable to receive any new messages in his inbox. After following the procedure I described above, I was able to send a message to him, and it appeared in his inbox. Since then, another 16 messages have been delivered, and the message files are in the inbox, but they do not appear via IMAP, nor does reconstruct see them. I'm at a loss. I've moved that mailbox aside, and just re-created his inbox using cyradm. I hope that finally allows this user to receive new mail. I suspect, though, that if he or I were to drag his old mail back into his new inbox, the problem would re-appear (since that's basically what I did last time). It seems like something in one of the mail messages is leading to corruption in the index, although that seems improbable. ?! - Geoff ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
