new user created via webmin can't rcv mail.

[jerryk]

hello,

I have a RH9 server running postfix and webmin.

When I create users e.g. joe/mary/bob

then use our squirrel mail client to send:
to: joe
subj: test

I get this error:
Transaction failed
Server replied: 554 <sue@gmrv.com>: Sender address rejected: Access denied

Is webmin failing to set up key user information needed by postfix?

This might help narrow down the problem.

This machine has 7 users who can all email each other.


I've created 2 users, who can email each other.

But the new users cannot email the existing ones, or vice versa, without getting the error mentioned earlier.


Many thanks for any opinions (even guesses) you can offer.

Jerry
