smtp authentication for linux vps server

I have a VPS server (running linux and plesk) from 1and1. Unfortunately, plesk adds a new mail account for a domain and allows smtp authentication for sending mail through the server but there are two problems.

1.) if mail is sent out to the domain itself even though the server is not really the authoritative MX mail server for this domain, it will attempt to deliver locally rather then resolving the actual MX record for that domain on the internet.

2.) if I create a different domain to send from, plesk and the vps require that I use that email address which is setup as a mail account for this alternate domain to be the from address when sending mail.

I believe plesk is using postfix.

I believe I need the following.

1.) probably need to disable plesk.

2.) create a smtp authentication so that the end user who is authenticating can use any from address they wish. This way, we can send email to any domain we wish as this server will not be the main mail server (authoritative MX) for any domain.

(No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).

## Platform

Linux SMP Mon Nov 17 18:41:14 MSK 2008 x86_64 x86_64 x86_64 GNU/Linux
