One of my users is seeing duplicate mails occasionally too. Client is
Sylpheed with POP3. It is quite seldom, maybe twice a month, using
POP3 several hours a day. We've been seeing this for some time now,
including up to rc13. Haven't tried rc15 yet. We haven't found a way to
reproduce this behaviour. Mailbox format is mbox.
The mbox file is on a local filesystem, the index files are on NFS
(actually, ~/Mail/INBOX points to /var/mail/$user).
I have "mmap_disable = yes" and default locking. Client and server are
recent Linux kernels. Server is running 32 bit userland with 64 bit
kernel on a BE machine. Client is standard 32 bit kernel and user.

pop3_uidl_format = %08Xu%08Xv

Nothing exciting in the logs, everything looks normal.
