I agree that Exim's ACL mechanisms have proven to be quite powerful for enforcing policies at the SMTP level -- and probably more flexible than the other players. However, with each step of "innovation" in the arms race about delivering and preventing spam and malware, countermeasures have led to accelerated growth in size and complexity of MTA software itself. Sendmail's main incentive for including the Milter interface may have been the unmaintainablity of their own configuration file format, but I believe that they have done a Good Thing by providing a rather simple API for extending and customizing the MTA. A short look at <http://www.milter.org/> shows that this API has proven quite useful for both experimental antispam features and site-local customizations. I believe that tight integration of the Milter interface into the ACL system will make Exim even more powerful. You may think of it as a generalization of the content-scanning API. Do not fear: There are no plans to turn Exim into Sendmail that I am aware of. ;-) Cheers, -Hilko -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
