[S.u.S.E. Linux] Trouble with Netscape mail function

Now that I have a ppp connection with ATT Worldnet (thanks to the good advice I received from this group), I'd like to set up Netscape 4.04 (Navigator/Communicator) to handle my e-mail, but when I tell it that my incoming mail is handled by postoffice.worldnet.att.net, I get an error message telling me that Netscape never heard of postoffice etc. So I must be doing something radically wrong, and I would appreciate some more good advice. Thanks in advance. Bill Madsen in St. Louis -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
