Mac Forum / Applications / Outlook Express / January 2005

I'm using os 9.1 (iBook), IE 5.1 and OE 5.0.6.  I'm able to send email ok,
but can't receive email (POP).  My ISP wants the POP port at 995, which I can
set by editing my account.  But when I click the box to overide the default
(whatever that is?), it won't stay "clicked" after I close the options box.  
My ISP (ATT) told me there is something blocking use of this port and that's
why the box won't stay checked.  I have no firewall active and don't use any
virus protection s/w so I can't image anything blocking this port.  (I also
have Netscape installed and it works with the modem for dial-up options, but
preferences doesn't say anything about port numbers.)  I can't find more
information at Apple, Microsoft knowlege base or ATT to help me.

How can I fix the port blockage?  (Isn't there some way to manually set
internet ports in os 9.1?)
