[cobalt-users] No such user here

["Achieve Website Design" <info@xxxxxxxxxxxxxx>]

Hello,
Since updating my Raq4 server with the latest patches
RaQ4-All-Security-2.0.1-14559.pkg and RaQ4-All-Security-2.0.1-15417.pkg , I
have being receiving the following message from Logcheck:
e.g. Jul  2 06:42:44 ns sendmail[32571]: g625giq32571:
<dconnolly@xxxxxxxxxxxxxxxxx>... No such user here.

dconnolly is the username/email that I use for one of my main sites, and I
do infact seem to be receiving mail O.K.

In addition however, I have also just recently setup  the Cobalt Mailing
List on the same site for which this email address is used, and am wondering
if this has something to do with the message?

Thanks,
Declan.
