Postfix SMTP authentication.

[seanbranagh]

I am switching from cPanel hosting to a VPS with Virtualmin. With the cPanel server users were required to use the option in Outlook etc "My outgoing server requires authentication" and set it to the same as the incomming server i.e. name@domain.com and their password. With Postfix on the VPS the SMTP authentication will only work with name-domain.com despite the fact that the incomming server accepts name@domain.com as there is valid Unix users name@domain.com and name-domain.com. How can I make the SMTP server accept the Unix users name@domain.com? I really don't want to ask all my users to start changing this setting.
