Sendmail wasn't really the first per se, but it was the first that worked well. In the early 80s there were a lot of competing email protocols and systems and implementations, and Sendmail could talk to all of them, in a "bug-compatible" way. This is also why sendmail.cf is so bewilderingly flexible and complex.
Later email systems like Postfix and qmail in the 90s had it much easier as they operated in a much simpler ecosystem.

At least MMDF was (a little) earlier. Maybe it lacked some features compared to sendmail? It ran at several university sites at least. It was an early adopter of least-privilege architecture, predating qmail by a lot.
Worth remembering that Sendmail was, generally speaking, first. Shoulder of giants and all that.
