As MailScanner parses the message then it should be fairly easy to write
the to_address to a file, or even hold it as a global hash shared between
the perl processes. When the recipient replies, if they do, then the hash
could be checked and allow the message through without any checks. Or if
using a file the whitelisted entry can be looked up.
A hash value could be created for the time the message was sent including
the to_address, and then reversed on its way back in. If within a
pre-determined time it passes through okay, or it has the normal checks
This would be a interesting project to work on. Anybody interested ?
