[Exim] mailer > program help

Greetings,

Does anyone use programs such as sendpage
with exim?

This is what I have already running with sendmail,
and I do not want the users to have to change...

user@??? is sent to the local program
sendpage, and the message is then sent out via
sendpage to alpha pagers.

I find the configuration of exim a bit different than
sendmail, but the simplicity is refreshing...
