Here's a line from my maillogs for today. This is 'cause you're
using an MTA from home on a dial-up... yes?
Nov 5 09:41:43 server sendmail[31822]: JAA31822: ruleset=check_mail,
arg1=<kabir@zenarchist.citenet.net>, relay=IDENT:root@g68-229.
citenet.net [207.183.52.229], reject=501
<kabir@zenarchist.citenet.net>... Sender domain must exist
You're going to have a lot of rejected mail as sendmail 8.9.1 becomes
more prevalent as it rejects messages from sources which do not
reverse resolve via DNS. The solution is to masquerade the envelope
and use your ISP's MTA as your relay. For a more complete discussion
on how to fix this see:
