I'm not familiar with Sendmail and only tried it on Exim.
Technically, you can request SMTP authentication and all modern mailers
support it.
Netscape Mail supports PLAIN authentication (just a passphrase), Outlook
prefers LOGIN, Evolution supports them all, including CRAM-MD5 (a nice
method, prevents passwords from being grabbed over the line, but the
downside is that you need to keep cleartext passwords on the server).
Since you cannot guarantee the passphrase goes through a secure link
(you can force them to use SSLed POP3 and SSLed IMAP, but you cannot
the block SMTP port to outsiders), you might prefer giving out the same
passphrase to all users in the company and tell them to use PLAIN auth
or LOGIN auth with known user/password. After all, what's ssh's worth
if lusers keep sending their password in cleartext all the time?
