After updating mail/courier-imap package to 5.0.0, there was a problem that users using POP3 received a mail twice, or timeout when a lot of mails were stored on the server.
This bug has occurred in version 5.0.0 and seems to be fixed in 5.0.3.

* pop3dserver.c (readpop3dlist): Be able to update
courierpop3dsizelist from version 2 to 3 in place.
(do_retr): Instead of returning an ERR to a non-Unicode client,
handle Unicode messages by wrapping them as an attachment.

* pop3dserver.c: update Courier-IMAP to support UTF8 POP3. Update
version of the courierpop3dsizelist cache file.
After installing 5.0.3 compiled manually the problem was fixed.
So I think that it is better to update mail/courier-imap to >= 5.0.3 or put comments in /usr/ports/UPDATING.
Thanks for pointing out the new fixed version.
I'll start working on the update.
