I am using postfix as a relay MTA, i.e. the MX points at it, it applies various filters and then relays the mail to final systems.
Is it possible to configure postfix such that say some header checks are applied to certain domains that relay mail and not apply those checks to other domains? I'm using header checks as an example, I'm thinking basically any option I would like to be able to enable/disable for a given relay domain. Is this type of setup possible? If yes, can you give me some starting points for reading. Thank you, Chad
