POP3 Timeouts?

    I am having a problem where long POP transactions are being closed by
    the server.

    I turned on per-user debugging, but didn't actually see the problem
    until I ran a packet sniffer(wireshark) on the server.

    The transaction goes as follows:
    1) Client connects/auths
    2) Client lists mailbox contents and retrieves messages in order
    3) Client requests a large message, server send the message
    4) Client issues the dele command, server issues a TCP RST (client
    obliges with a Fin,Ack effectively closing the connection)

    No errors are present in the log and the per user debugging makes it
    look as though the client never issued a dele/quit.

    This appears to be the POP timeout as increasing the timeout allowed the
    download of larger messages. Is this the way the POP timeout is supposed
    to work? I would assume as long as data is continuously being requested
    by the client the timeout would not be counting. Is the timeout counter
    instead based on the time between commands issued by the client?. I am
    using Cyrus 2.3.1

    Thanks,
    -Blake
