I recently moved my RH 9 Mailsystem to a new server with Fedora 1. In the old settings, users had mozilla configured that way, that they had to use there user and password to send mails (Mozillla Mail -> Mail & Newsgroup Account Settings -> Outgouing Server (SMTP) -> Use name and Password).
Now with the new Server they have to deactivate this feature.
Which sendmailoption do I have forgotten? ;-)
Read the Sendmail SMTP AUTH HOWTO at:

For Fedora, when you are editing sendmail.mc, remember to to change the "A p" in confAUTH_OPTIONS to just "A" (that is, remove the "p"). I have not had time to make this change in the actual HOWTO.
