I have a problem. We have been using the address postmaster@bennettandco.co.uk for quite a while, and just moved to a dedicated server. However, when I try to add the email address of postmaster it says it is already an alias. I understand that it is standard for postmaster to be there, but in our case I need it to be it's own mailbox.

How can I achieve this on a Raq4???

Jim...

Can you set up another user and alias 'postmaster' to that user?

It won't let me do that either

still no joy on this... can anyone help me please? :(

I think that it is somewhere in the cobalt gui, something like admins mail adresses you should be able to change them but I'm not sure where though...
Is it the user it refuses or the alias? if it's the user create a user with a different name and give him postmaster as alias (but I think that you are already past this stage from what was written above, just making sure ...)

Hoot

On a cobalt raq, all email sent to postmaster@anydomain.com are going to the admin emailaddress of the server

This is defined in the alias file (etc/aliases):
# Basic system aliases -- these MUST be present.
MAILER-DAEMON: postmaster
postmaster: root

So If you want to change the address, you have to do it in this file, but it will be in effect for all domains on your server

If you change anything, you have to do that after:
1. /usr/bin/makemap hash /etc/virtusertable < /etc/virtusertable
2. /etc/rc.d/ini.t/sendmail restart

You have to give a username of a user on the system
