Not always... look at a cluster of webservers - their MX is elsewhere,
but they do run qmail-send or something similar, in order to send
outgoing mail (cronjobs, mail from web interfaces ...).
Smarthosting all of them through a central server is not always feasible
Why should you care if forward DNS doesn't match rDNS by the way?

Configuring rDNS isn't the problem at all. Getting your IP provider to
delegate the in-addr.arpa zone to you? Well, that's often a real
problem - even if you give them the appropriate bind config snippets to
do this.
