Dec 14 00:15:54 vm dovecot: IMAP(####@####): Maildir filename has wrong W value: /var/vmail/#####/####/cur/#########.M###########.??.????.??.??,S=4951,W=5057:2,RSa
Dear Dovecot elite,
This morning I woke up to find my mail server hard disk controller had gone crazy and decided to corrupt my file system. After over eight passes with the fsck and a new machine I have mostly recovered but this being a personal server the backups were a half-job. So for speed I recovered the mail directly off the bad file system. Most of the data was fine but a few files were corrupt and as a result I have found Dovecot to be a real pain when it comes to handling a wrong W value. I am having to separately look at the mail.log and just systematically remove the W value as a quick work-around. But it seems to me that it would be much easier to have this done by Dovecot when it realises it has this wrong value, especially as Dovecot seems to drop the connection of that user after encountering this problem.
Can I suggest as an improvement this scenario is handled better? I saw one posting which said "this should never happen" but clearly it can and I think there could be better handing of it perhaps?
Regards,
Bob
