[Dovecot] Disconnected for inactivity in reading our output top=0/0
Would someone please help with this error.
Using: dovecot-1.0-2.rc28.fc6 On: Fedora Core 6
130 users all connect remotely via ADSL to server to pop their email. None of them have any problems at all with pop3. 3 users in one office, connect to the server via a NAT'd ADSL.
Intermittently those three users will get a timeout error, Logfile shows:

99% of the time everything is perfect, it is only the three users in the one office that get this error, it is of course the head office for the customer and so they are very upset, because they get timeout errors on their email clients.
They are using different versions of outlook, and outlook express, I have deactivated all nortons email scanning etc
Have set the three email clients to pop mail at different times, eg. 7, 13, 17 minutes to try an avoid the possibility of simultaneous pop requests from the one IP address.
Dovecot -n

We have a similiar situation every few weeks. Outlook gets confused by a certain (spam) message in the inbox. If we remove the message (using the imap web mail frontend) the problem is gone.
As you can see in your log file, one message is downloaded (retr=1/0). I _think_ the client does not recognize the end of the message for whatever reason and then waits forever.
Unfortunately I did not have time to investigate the problem further. Our system is dovecot rc17, maybe upgrading to 1.0 helps.

Did you figure out anything? Enabling rawlog (http://dovecot.org/bugreport.html) for those users and looking at them might show if the mails contain something special that causes the client (or Dovecot) to break.
