Email Error When Sending Mail Via Vbulletin

Hey Hoping someone can shed some light on this.

When sending an automated email from a vbulletin forum, i end up with the following error in my mail.log.

Code:

Jan 30 19:14:10 server1 postfix/pickup[28403]: E38709F8552: uid=33 from=<www-data>

I'm running Debian Etch and the latest ISPconfig version 2.

Followed the server perfect server install as well.

Any ideas?

 

It's in a datacenter

 

No that's an external ip address where the email was sent to.

 

You're relaying through that server, right? Are you sure the relay is working?

Did you receive a sender non-delivery notification? If so, what's in it?

 

I'm not relaying I don't think. That's the ip address of anotehr server I own which is where the email account that should have got that email is based. Completely seperate from the ispconfig server.

I have nothing in the inbox for the domain of the vbulletin although i do have a catchall email set up.

 

Just as an extra thought, I can send an email through roundcube to the same email that is bouncing the vbulletin email if that helps?

 

Till: This is the errors on the other server in the exim_reject.log:

2009-01-31 17:50:29 H=(server1.komodoarcade.com) [212.117.165.30] sender verify fail for <[email protected]>: The mail server could not deliver mail to [email protected]. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.

This seems to have solved the problem for vbulletin. I selected an option in the forum admin section under email for this purpose.
