Somebody mentioned "configuring it is hard--why does the user have
to know SMTP subtleties", and that may be a valid complaint against
the primary part of send-email. The solution for that is not to
discard it with bathwater, but make it just as easy as other MSAs,
say, Thunderbird, to configure for an average user who can configure
these other MUAs.
Sadly, the average user does not use an MUA, SMTP or IMAP, anymore.
It's all webmail or apps using proprietary protocols.
