In principle ssmtp is a drop-in replacement from sendmail, but it 
doesn't have full sendmail functionality; it will ignore or bomb on 
most command-line options.

All that ssmtp can do is forward mail to an SMTP server.
It can choose which server selectively based on the From address.
It doesn't queue; but I use it on a frequently unconnected machine, with 
a homegrown script to queue mail in such a way that I can ssmtp it 
later.  ssmtp has the benefit of being trivial to configure.

Exim is much more powerful, and almost certainly can be used as a 
complete drop-in sendmail replacement in the way you want.
