Hi all:

I think your domain got into a black list or a Black hole where you can
not send mail to anyone in the NET. You have to go to the SPAM
organizations and probe to them that you fix the problem and you were
not intended to do the spam. Then they will delete you from that list.

Try searching for spam on the web and you will see a lot of sites that
are members of that org. They will require you to do an online test in
order to submit your request for the deletion from the black list.

Good luck man, been there, done that....

Hi there,

Yes I believe that's the problem. Usually most mailclients only sen
logon credentials to the mailbox, and not the smtpserver, even if they
are onm the same machine. So, like in Outlook where you specify logon
details separately for 'outgoing mailserver, you need the same in the
Netscape client. If you can't find such a setting I don't think it's
gonna work...

HTH,
Örjan
