sendmail relaying

Fri Jan 3 21:48:48 EST 2003

Well, you see, therein lies the problem.  When Mozilla tries to send the
email, it immediately gives me the relaying message.  It doesn't send ->
bounce error.

That's why I'm having problems trouble-shooting this problem.  I have no
debugging info to help chase down the problem.

I'll reboot into linux & see if I can get pine to supply more info.
