Sendmail started life as "delivermail", which predated *both* TCP/IP and SMTP, and was released in 1979. Mail then was implemented as a series of hackish extensions tacked onto the FTP protocol, which rode on top of the old ARPANET NCP protocol. This software evolved into sendmail with the advent of SMTP. When sendmail was released with SMTP support, DNS was not yet in use
And back then the TCP/IP Internet wasn't the only network around . Some of the complexities in Sendmail were there to handle mail via UUCP (ever seen a circular bang-path?) , and transfer mail to and from DECNET and IBM SNA networks (EBCDIC anyone?) and other such fun stuff.
The newer programs pretty much only deal with the TCP/IP internet (and short-haul UUCP) and that lets them strip down a lot.
