/etc/alias

Hi,
I have succesfully configured RT and I am very pleased with myself :wink:

I just have one question:

I am using /etc/alias to call the mail prog. I notice it has its own
error messages which it mails back to the the user, but they also get a
Mailer-Daemon message back as well…

I have tried redirecting the output to /dev/null, but make no difference.

This is not a great/urgent problem as I dont plan on have many error
messages but all the same I would be grateful of any suggestions?

Regards

Barnaby Puttick.
