As Eric (Allman) used to say, the later was created to solve the "header of the week" issue he was fighting at the time. At one point there was an smtpd that was written by BBN. I don't remember why Eric did not continue to use it when he wrote sendmail. At Berkeley at the time, the only system that needed it was Ing70 later IngVax [which of course Eric managed] because that was the Internet connection for the systems on campus. We all ran the BerkNet to the ingress systems for Internet mail or to ernie (later ucbvax) to do UUCP mail. He and I talked about about it once, I had always wished he had left the different "connector" programs alone and just let sendmail be a header rewriting system. uucp just handed off to /bin/mail for delivery. I thought delivermail did the same thing. I think it was Kurt Shoens who did the splicing of Berkeley delivermail to uucp, but again I've forgotten - a long time ago. The SCCS headers might say. memory was that Kurt and Eric Schmidt Clem

Amen - I've always said that sendmail became what it was because it was the SMTPD that went out in 4.2 and followings. If the original BBN code had been left alone, since most people did not have the issues Berkeley did, they would never have bothered with sendmail.cf. But because it was there and >>conceptually<< you could do all sort of stuff with it, people tried. We'll never know. I was a fan of MMDF for years and later qmail - but I switch ccc.com to google when the first offered it small folks like me 8-10 years ago and I never looked back.
