Hi All,

I've been trying to create and alias for a user and disty group, but when people try and send to it:
mcstaff@mercedes.adl.catholic.edu.au on 5/03/2009 12:34 PM

The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.

< bne008mr.server-mail.com #5.0.0 X-Postfix; host mail.mercedes.adl.catholic.edu.au[] said: 550 #5.1.0 Address rejected mcstaff@mercedes.adl.catholic.edu.au (in reply to RCPT TO command)>

Now it appears this has happened since the upgrade to GW8, because all the aliases prior to the upgrade are working.

Any ideas?

Thanks in advance.
