SMTP errorcode 451 does not send mail delivery failure mail
« on: January 04, 2005, 12:34:45 AM »
Hi,

On of our clients is complaning that her mails are not answered.
But the recipients never got her mail.

The clients mailserver is a SME 6 contribs version that is connected to the internet via ADSL with a dynamic IP address.
 
Our logfile /var/log/smtpfront-qmail/current shows:

rblsmtpd: 62.xxx.xxx.xx pid 27710: 451 Dynamic IP Address See: http://www.dnsbl.sorbs.net/lookup.shtml?62.xxx.xxx.xx

Allthough a smtp error is raised, no mailer deamon delivery error message is returned to our customer.

Both sides use the SME 6 contribs version.

How to enable that this kind of rejected email generates a mailer deamon delivery failure notice?


Cheers
