sample:
Oct 17 22:01:02 fsn1 sendmail[28991]: WAA28991: ruleset=check_rcpt,
arg1=<MLB_20011004_CIN@xxxxxxx>, relay=AC81C4DC.ipt.aol.com [172.129.196.220],
reject=550 <MLB_20011004_CIN@xxxxxxx>... Relaying denied. Please POP before
sending.
Yes, and the thing that really hacks me off, is that there are hundreds at
a time. "relaying denied" You would think they would run a test case of
one, before sending hundreds at a smtp server that was going to reject
everything.
