Hi misc@, I just started to read OpenSMTPD sources. Regarding the latest discussions on tech@, there maybe seems to be the need to instruct OpenSMTPD listeners to behave differently when acting as MTA or MSA. Reading man smtpd.conf(5)[1] there is an option to add a tag to the "listen on [socket]" directive. Those tags are currently used in "match" directives. Maybe this could be extended to add well known tags to a listener to control operation modes like MTA or MSA. Both of this is documented in corresponding RFCs. Is there any interest for me to take a closer look any maybe come up with some patches tech@? I am really just starting to read OpenSMTPD sources. If there already is a way to instruct OpenSMTPD listeners to behave differently regarding to - for example - handling message ids based on in either MTA or MSA mode, please let me know. I would like to avoid spending time into this, if there is no interest but I think there really should be a way to configure listeners to specific operation modes like MTA or MSA.
