[cobalt-users] RaQ4 'domain of sender does not resolve'

["Eddie Bishop" <eddie@xxxxxxxxxxxxxxxx>]

My RaQ4 is rejecting an incoming email. Maillog says:

Apr  6 12:16:11 www sendmail[32183]: g36BEti32183: ruleset=check_mail,
arg1=<[sender-name]@RADVIEW.COM>, relay=finch-post-12.mail.demon.net
[194.217.242.41], reject=451 4.1.8 <[sender-name]@RADVIEW.COM>... Domain of
sender address [sender-name]@RADVIEW.COM does not resolve

I have replaced the guy's name with [sender-name] but everything else here
is genuine.

The sending server keeps trying every four hours.

I think Radview are having some DNS problems because my users can't send to
them either. This doesn't really matter, but is there an easy, temporary way
to make the RaQ less fussy so that this message can come in despite the
resolution problem?

Many thanks
