SMTP Auth in Netscape 6.X and 7.X

Open Netscape Messenger 6.X or 7.X
Click on Edit and come down to Mail/News Account settings and click on that.
Select "Outgoing (SMTP) Server" from the list on the left.
In the "Server Name" field type in mail.jellico.com
Check the box that says "Always use username and password".
In the username box just below that type your username (the part of your email address before the @ sign)
Click "OK" and now your Software will authenticate itself before sending out e-mails.
