The milter interface chats over a socket to a long-running process so you don't have to initialize it every time. MimeDefang also multiplexes to several slaves that do the scanning work so you don't have to serialize everything either.
I think spawn acts like an inittab entry, it hangs around itself and if the thing it spawned ever dies it cooks a new one. I believe that postfix is also using Unix sockets to communicate with external apps. Pass on the muxing aspect I only know enough to get gps working.
I realize often the skills one acquires managing a particular setup can outweigh moving to another platform even if it is better, but one look at the need for a Makefile to translate one incomprehensible config format into a config format that sends grown men insane convinced me to back the Postfix horse :-)I'm still missing the 'better' part. And Makefiles have always
Fair enough, I did stick that cart before the horse.
been a useful way to automate repetitive tasks - even better when someone else has written them and embedded the execution in the program startup script.
That must be why so much other software manages their config by converting it into gibberish by build tools, instead of the naive and unprofessional method of parsing a single level of config straight.
-Andy BTW just saw this fly by Package : sendmail Vulnerability : programming error Problem type : remote Debian-specific: no CVE ID : CVE-2006-1173 CERT advisory : VU#146718 BugTraq ID : 18433 Debian Bug : 373801 380258 Frank Sheiness discovered that a MIME conversion routine in sendmail, a powerful, efficient, and scalable mail transport agent, could be tricked by a specially crafted mail to perform an endless recursion. For the stable distribution (sarge) this problem has been fixed in version 8.13.4-3sarge2. For the unstable distribution (sid) this problem has been fixed in version 8.13.7-1. We recommend that you upgrade your sendmail package.
