Advice needed with Whitelist Rules

[hden at kci.net.nz]

Although this appears very similar to my recent help request [resolved
now, thanks Alex], it is in fact totally seperate.

I'm trying to track why some email that should be whitelisted at times isn't.

In my whitelist rules, I want to whitelist email from anyone from a
certain domain, so in whitelist rules have ..

From:   thisdomain.co.nz   yes

Question, would this also whitelist email where the 'From' field in the
email header is in the following format? ..

From: Bill Smith <bill at thisdomain.co.nz>

and, if not, what needs changing?

Cheers!
Dave
