Helo all,

I'm working on a migration from qmail+courier+maildrop to postfix +dovecot1.1+lda and today the logs has too many strange messages like this:

Jun 12 10:51:22 mailserver03 dovecot: IMAP(xxxxl@xxxx.com.br): Broken file /data/services/dominios/xx.com.br/m/ma/mapel//Maildir/.Sent/dovecot-uidlist line 29: UID larger than next_uid (535 >= 535) Jun 12 10:51:26 mailserver03 dovecot: POP3(xxxx@xxxxx.com.br): Broken file /data/services/dominios/bx.com.br/n/no/nordeste//Maildir/dovecot-uidlist line 2: UID larger than next_uid (12 >= 12)

Should I worry about this? Why dovecot-uidlist is getting broken?

There's no Dovecot v1.0 used anywhere? How did you get these dovecot-uidlist files created? Did you use a Courier migration script or rename them manually?

These error messages can happen only when Dovecot reads version 1 format of the dovecot-uidlist file. This format is created by Dovecot v1.0 and Courier. After Dovecot v1.1 has updated the file it's in version 3 format and this error message can't happen anymore.

So apparently some versions of Courier can also update the courierimapuiddb by appending new entries instead of rewriting the file and updating the next-uid field in the header line? What Courier version were you using before?
