Urgent Help Please!! Trouble contacting a pop3 server through LAN

    I have 2 machines on a LAN with 45 machines that will not connect to
    a local ISP's mail server from the LAN's high speed internet connection.
    The machines log onto the server fine and the internet works great, but
    the connection to the ISP fails whether using Outlook or Outlook Express.
    I tried contacting the mail server using Telnet and it fails as well. The
    machines work fine outside of their network and all other machines configured
    the same way work fine. I have tried connecting other machines to their
    location
    and they work fine. Any suggestions would be greatly appreciated. Thanks,
    Tom

    It sounds to me like port 110 is blocked if using POP3 or port 25 is blocked
    if using SMTP.

    Use Outlook Express?... Get OE_Quotefix:
    It will strip signature out and more

    Keep a back up of your OE settings and folders

    Is your internal domain name same as your registered domain name?
