M4 isn't even the configuration language?!, it is a standard macro tool package that gathered bits of configuration together to make configuring it a bit easier for standard setups. Having the configuration bits wrangled with M4 came about much later in the lifecycle. Most people haven't used M4 for anything else other than sendmail config bits. Sendmail the software was around for almost 2 decades before Sendmail Inc was formed. The Bat book was the original tech support.. The Sendmail configuration is mostly a pattern match based setup. For back when there were 100's of different email system addressing ways, and 100s of gateways between them. If they had to only deal with the way Internet mail works today, they would never have had to have the complexity seen in the base sendmail config. If we suddenly had to deal with the email address complexity of the 80's, all the other email servers would fall over dead. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
