While your comments are generally valid, sendmail was ugly even then. It holds up because it has the capability to do all the things a Unix MTA needs to do, inertia, and lack of something else. > please remember that in 1981 a vax 11/750 with rk-07 > disk drives and 512MB of memory was a BIG deal and > significant cost. wasnt 1 SpecInt originally supposed to > approximate a single vax (dont pick nits ;) We used to call it MIPS, and for many years it was alleged that a vax 780 (not the whimpy 750 - had one of those - yuck!) is worth 1 MIPS. Someone ran SpecInt on one and found it really is worth only 0.5 MIPS. Architectually that was a beutiful little computer.
