[Dovecot] Pop3s duplicates

[Mark Adams]

Hi,

dovecot 1.0 rc6

Can someone please advise on my interpretation of the following logs,
Users are reporting duplicate email coming through to their inbox.
(user at domain replaced actual username and domain) There are also reports
of the connection seemingly freezing whilst the emails are being
downloaded (pausing at a certain amount of kB then continuing after a
minute or 2).

info: pop3-login: Login: user=<user at domain>, method=PLAIN, rip=89.192.*.**, lip=172.16.22.10, TLS
info: POP3(user at domain): Disconnected top=0/0, retr=4/183443, del=0/313, size=83779942
info: pop3-login: Login: user=<user at domain>, method=PLAIN, rip=89.192.*.**, lip=172.16.22.10, TLS
info: POP3(user at domain): Disconnected top=0/0, retr=3/183443, del=0/322, size=84201570

In the first instance the user downloaded 4 emails totalling 183443
bytes leaving 313 messages on the server. (outlook 2003 set to leave a
copy of messages on the server)

second instance user downloaded 3 emails, exactly the same amount of
bytes and left 322 messages on the server.

Does this mean the users connection was interrupted when downloading the
original emails and they attempted to be sent again a second time?  how
could it be that there are 9 emails left on the server if only 3 extra
were downloaded?

Any help on this would be much appreciated.

Thanks,
Mark
