Implementing per domain scanning

[Kevin Hill]

I need to implement per-domain rules for both virus and spam checks. Can
both "Virus Scanning =" and "Spam Checks =" point to the same ruleset? For
example:

MailScanner.conf:
Virus Scanning = %rulesdir%/per.domain.rules
Spam Checks = %rulesdir%/per.domain.rules


per.domain.rules:
FromOrTo:   *@domain1.com   no
FromOrTo:   *@domain2.com   no
FromOrTo:   default         yes

This would turn off virus and spam checks for domain1 and domain2 and allow
checks for all other domains.

Would this be the most efficient method?

Thanks,
Kevin
