POP3 failure

    Hey guys,

    have a curious problem here. I have a user here (using Outlook) attempting to connect to our mail server (RedHat w/ Sendmail). He can access his mail via SquirrelMail no problem, but any attempt to do so via Outlook cocks up

    doing a '$-> cat /var/log/messages |grep parameters' results in the following:
    Oct 3 09:08:42 BoxName pop(pam_unix)[20389]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=userX
    Oct 3 09:08:44 BoxName ipop3d[20389]: Login failed user=userX auth=userX host=wks151.Network.IE [host.IPAddr]
    Oct 3 09:08:47 BoxName ipop3d[20389]: Command stream end of file while reading line user=userX host=wks151.Network.IE [host.IPAddr]

    doing a '$-> cat /var/log/maillog |grep parameters' results in no pop3 activity

    Any ideas?

    Is Outlook set to try for an encrypted connection? Because other than that it looks like a password or user id failure.

    The maillog generally handles the sendmail connections and delivery. The pop logging should be in the /var/log/messages file - though this may vary on Redhat (I don't ordinarily use RH.).

    I don't think squirrelmail is using pop3 ?

    Are you sure pop3 is running on the server and is allowing access from other hosts?
    run telnet se.rv.er.ip 110 and make sure
    you're getting a prompt.

    Try configuring outlook to use imap.
    If squirrelmail is running on the same server as the mail service,
    it may just be configured to allow localhost connections.

    You don't say if this is just one Outlook user of many.
    Is he the only one who can't connect?

    From the log fragment it looks like most of the above are not the problem, but that he has a simple authentication problem.

    Compare with a known working Outlook installation,
    and reset the users password.

    Good Luck,
    NiallB

    Could you grab a TCPDUMP of the session.



    tcpdump -xX src or dst port 110

    It sounds like Outlook is buggering up somewhere. You might be advised to go with a different POP3 daemon.

    Regards,
    Phil.
