I have a Centos 5 machine running Webmin (all latest versions).
For the life of me I can't seem to figure out how to setup to allow a user to use tis machine as an outgoing mail server???
I want someone using outlook express to be able to setup abc.com as their outgoing mail server (incoming is already taken care of) and preferably using authorization to prevent open relaying.
Can someone give me a quickie step by step?
