Automating Mail receipt on Linux

I got your E-Mail address from the MAN page for PROCMAIL under LINUX
5.1.  I have an application where I would like to receive E-Mail from
various sites and process it automatically via a script for the purpose
of extracting data.  Is PROCMAIL and FORMAIL the tools I would use for
this?  If so, do you know where I can find sample code?  If not, do you
know what commands to use?  Linux version of mail doesn't support the -p
flag.

Thanks in advance.
