Definitely.

I'm sorry. I should have just guessed:

1) Maybe your mozilla client is doing some authentication
that sendmail (on your box) is not configured to do.

2) Maybe the servers you use need to be successfully 
POPed or IMAPed recently from your IP address before 
accepting SMTP mail from that address.

Sometime these problems are difficult to grind down,
but you are/were doing a pretty good job.

Good luck,

Troy
