I would think they'd all have a binary named 'sendmail'. Under that

 dpkg --search `which sendmail`

Probably, but I don't recall the level of detail that gives you. With postifx
its fairly straightforward to edit /etc/postfix/main.cf. More convoluted than
that with the package named Sendmail. The other's I don't know.
