I have the same issue, and a workaround (courier 4.0.2 vs dovecot-1.0.rc2).

In the user's Maildir/ directory, I run the following commands:

rm dovecot*
head -2 courierpop3dsizelist | tail -1 | awk '{print(1,$3)}' | sed 's/:/
/' | awk '{print($1,$3,$2)}' > dovecot-uidlist

And in dovecot.conf I have the following:

protocol pop3 {
  pop3_uidl_format = UID%u-%v
}

This has been tested and works for at least three mailboxes here with
>3000 mails (why these people still use pop3 is beyond me).


By the way, another server running courier 3.0.7 seems to simply use the
filename.
