Question on that.. in exim, if I specify something like this in the config

domainlist relay_to_domains = mysql;SELECT DISTINCT domain from domains
WHERE mx1='' AND domain='${domain}'; executes that sql statement for *every* message that passes through -
it does not just pull the list of domains once and cache it.  In the system
you describe above for MailScanner, does it execute the Rule for each
message that is processed? (I think it does, but I just want to make sure)
