Matthew,
Something like milter-regex might be a more reasonable solution.
http://www.benzedrine.cx/milter-regex.html
According to their man page you can do a regular expression match on
envrcpt, envfrom, header, body, etc.
Plus changes in the configuration file don't require a reset.
"The plugin regularly checks the configuration file for modification and
reloads it automatically."
Hope this helps.

I asked this on the Spamassassin list, and was advised I would have better
luck with ClamAV. I do have ClamAV running in several setups, but have never
done anything exactly like this.
My typical setup would be Postfix -> Amavisd -> ClamAV.
I work for a healthcare company. I have been asked to implement something to
block all outbound emails that contain patient names. We have roughly 35,000
names. I need to look for them in the format "John Smith" and "Smith, John".
These would be for outbound emails only. I would like to bounce them back to
the internal sender with a custom message (I can handle that in Amavisd). I
realize this would be a totally oddball setup, so I have no problem
dedicating 1 or 2 servers to it.
We would script an export of patient names from our Patient DB every night.
So, I basically need to know if it would be practical to build a ClamAV DB
file with 70,000+ names to be used to search an email for a match?
If all this is practical, would it be possible to allow for a text string in
the email to flag it so it would be allowed to have one of the forbidden
names in the email? I figured this may be an Amavisd question, but I don't
see an option for anything like that there. I figured I would try here. We
would want users to be able to put a code such as (override) in the subject
to bypass this restriction.
I'm not saying this is the most brilliant idea in the world. It is just what
I have been asked to do.
Any tips would be greatly appreciated.
Thanks,
Matthew
