how to find pine messages

still touching on the basics here:

first of all where are my received messages stored in pine?

/var/spool/mymail

is not it.

i guess i cant start my script without knowing this. because i need to move those files into a seperate folder and so on and so forth.

I can prolly do a grep or egrep to identify messages from a certain person. Like grep "^From: Bill Gates | nl" and then ofcouse putting the new lines back.

But after countless attempts its still not working. Experiencing program hang from executing the script.

Hints are apprecaited
