hi, i need some advice.

first, i want to limit the email access to only those addresses in our
domain. so i want to let [email protected] send and receive with
[email protected], but [email protected].

second, i DO want to allow access to outside world, but only for my
employees that are on a white list.
if our mail server gets an email addressed to someone who is not on the
white list, then it gets bounced.
if [email protected] tries to send an email, but [email protected] is
not on the white list, then it bounces back to john.

we need everyone in the company to be on email for internal communication,
but we only want to provide outside communication selectively.

whats the best way to do this?

I think the easiest solution is through MailScanner.

Given you are probably going to implement spam / antivirus detection on the server, you should be able to accomplish what you want via MailScanner's sophisticated rulesets which allow all kinds of control using From or To combinations. I would use the install scripts / services at which will give you the most flexibility (and consider not using the front end so users cannot make changes on their own).

Q: How many email addresses do you anticipate having in a whitelist?
