"The mail program was unable to send mail"

[fork]

I set up my mailing list, and signed up myself as a recipient.[nbsp][nbsp]The link in my email to confirm was:
[nbsp][nbsp] discussions-sc.984076961.gnikaeapnbjcaenenkcd-forkush=msn.com@mlm.icuclick.com

When I clicked on he link, Outlook Express said the mail program was unable to send.

Never mind.[nbsp][nbsp]A Netscape install changed my associations.
