How to singularly scan an email?

[Peter Ong]

Hello Everyone,

How do you single out an email to be scanned? I will explain.

In my mail server, there are many domains. Every domain except one is exempted from spamassassin. I did this in spam.whitelist.rules:

To: *@foobar.com yes # don't scan this one through spamassassin

However, there is one email inside of @foobar.com that I want scanned in spamassassin. So, I added this to the same file:

To: user at foobar.com no # but scan this one through spamassassin.

Did I do this right? Is this effectively going to scan emails going to user at foobar.com, but not for any other in @foobar.com? Thank you.

Peter
