I would suspect that most people don't make use of sendmail, nor even
need to.  They'll use a mail client, and configure it to use their ISP's
SMTP server while setting up the rest of the POP or IMAP settings.

Those keen on running a local server will need to customise theirs, and
know how to do.  Just the same as running any other public server (HTTP,
FTP, or whatever else).  Sendmail does need to be tightly configured, by
default.  Historically, mail servers are one of the most abused on the
internet, and one that causes the most problems for other people.

If you're suggesting that the client should accept all mail by default,
I don't think I'd go along with that.  Perhaps if it was easy to
configure that behaviour.  It'd certainly need to be configured to not
deliver externally, by default, at the same time.

But, most people are going to need to do a variety of things to be able
to post mail.  They'll need to configure their system securely.  They'll
need to have a real domain name (own one, or have permission to use some
other one).  And if they want to receive mail through it, they'll need
to configure external services to send to their SMTP server and/or
organise public DNS MX records.
