    Hi Ed.

    Here is how I would go about diagnosing:
    Log into the pop server machine:

    # netstat -lan

    That will tell what ports your machine is currently listening to. 110
    should show up in the listing similar to:

    tcp 0 0 10.253.0.150:110 10.253.32.76:2952
    TIME_WAIT

    If it doesn't ,then your pop daemon is not running.

    If it does show up, then try telnet:

    telnet localhost 110
    or
    telnet 127.0.0.1 110

    If that connects (you should see something like:)
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    +OK Qpopper (version 4.0.3) at locahost starting.

    Then that is working. If it doesn't show up, then it's listening on 110 but
    not letting you connect (which would be VERY strange. Ihave not seen that
    before).

    If working, now try to telnet from another host to pop3 host using an ip
    addres you know will connect. e.g. if you can ssh or telnet or ftp from
    host1 to your pophost, then go to host1 and see if you can get a telnet
    connection to your pop3 server on port 110.

    If that works, then there's a good chance your pop3 server is fine. Next
    telnet from the machine that has your pop3 client to the pop3 server port
    110 . If that works, now we know it is a misconfiguration in your mozilla
    mail client which brings me to the next paragraph.

    > But let me ask you: how would I do as you suggest, "Make

    What I mean to say is

    "make sure the pop server in your pop 3 client's config is the correct one"

    Since you were being asked for ed@pop 's password, I was thinking that
    perhaps in your mail client you only put "pop" as the server name. Make
    sure your client resolve that correctly to your connection is all.

    For example, at a previous place of work one person wasn't getting their
    mail. Their pop3 server config siad "mail" which was the exact same as a
    person next to her. What happened was that the person next to her had the
    correct search domains (including "internal.company.com" so that her client
    would try "mail.internal.company.com". The person's machine who did not
    work did not have that in there so we put that in there. I myself prefer
    using the full hostname right in the config instead of relying on the search
    order so on my machine personally i had the pop3 server listed as
    "mail.internal.company.com" so I knew it was going to the right place
    (instead of just listing "mail"). (note, she did have "company.com" in her
    search order, however our firewall was blocking "mail.company.com". When
    her mail client attempted to acess mail.company.com it would go out the
    firewall to the internet and try to come back in again which is why she was
    getting timed out)

    Does that make sense?

    You may even want to test it first by putting in the IP address of your POP3
    server into your mail client's pop3 server config field. If that doesn't
    work, then there's a connection problem. if it does work, then there's some
    hostname resolution problem.

    Hope that is mor clear . Good luck

    Ben
