Hey postfix-users and -abusers, is there a postfix way to make use of a map (domain based) for the selection of a (before-queue) smtpd_proxy_filter? The idea is to send some domains through a certain smtpd_proxy_filter and maybe skip the filter for others alltogether.
I do understand that postfix does not know the recipient domain in advance. But what about smtpd_proxy_options=speed_adjust? With that option used, postfix has the whole message. If there is no way of making postfix do this, are there plans to implement map support for before-queue filters? What other options does one have to switch between multiple before-queue filters per domain? Apart from using different postfix instances I mean. Thanks for your ideas, Regards Christian
