Hello,

I recently converted my 300+ email user system over to Dovecot. It is working fantastically, except for UID sync errors. I read everything I could find and only saw others with those problems in version 0.99 below. My log shows errors like this all day long for pretty much all users:

dovecot: Jun 25 19:12:46 Error: POP3(nmichel): Maildir /home/rtb/users/nmichel/.Maildir sync: UID < next_uid (42 < 43, file = msg.oP8c:2,) dovecot: Jun 25 19:25:59 Error: IMAP(lcrowe): Maildir /home/dentist/users/lcrowe/.Maildir sync: UID inserted in the middle of mailbox (70 > 4, file = msg.AM81:2,)

When this happens, IMAP and POP3 drop the connections sending errors to their clients. I use squirrelmail over IMAP and some new emails never appear until I delete the index files.

I have tried deleting indexes, and the problem continued. I went from dovecot-1.0.beta3 to dovecot-1.0.beta9 and still happens. The only way it doesn't happen is when I append the INDEX=MEMORY trick as in:

default_mail_env = maildir:~/.Maildir:INDEX=MEMORY

but then it's all so slow for large mailboxes, it's painful.

Here are some of my specs: Linux kernel 2.6.15 Maildir Auth from /etc/shadow Users from /etc/passwd

Does anyone have any hints on where I should start?

Thanks in advance. I love Dovecot. I really hope I can get this resolved.
