[cobalt-users] Trouble with sendmail sending with shop

["Axel Denk" <cobaltlist@xxxxxxxx>]

Hello,
 
I am using a RAQ 4 with sendmail 8.10.2. I installed cauposhop from
www.caupo.de. It used to run under Redhat 6.x without any problems.
 
Since I use it under my raq, I always get error messages when the shop
tries to send the order confirmation email.  /var/log/maillog says DSN:
User unknown although sending emails to that address with a pop account
doesn?t seem to be a problem at all. Here a copy of the error message:
 
Jun 10 13:08:11 ns20071a sendmail[22533]: g5AB8B722533: from=httpd,
size=558, class=0, nrcpts=2,
msgid=<200206101108.g5AB8B722533@xxxxxxxxxxxxxxxxxxxxxxxxxx>,

stat=Sent
 
(1) The shop sends the email to 2 email addresses in the ?to? field. Is
that a problem?
 
(2) Ctladdr=httpd <- is that a problem, because it doesn?t show an
emailadress?
 
(3) When I forward the email to a local account it?s working. If I
forward the email to the external address out of the inbox, I get the
same error. Is the senders Email missing?
 
Any suggestions?

Thanks
