mail in linux

[Sandip P Deshmukh <deshmukh@escortsmumbai.com>]

i am new to linux.

i have been using mail 'windows' way. use some program like popcheck to 
download headers from various pop3 accounts. delete headers i dont want 
to download off the server. finally, use mozilla to download the 
remaining messages.

now, i am told, unix has better ways of handling mail. i tried setting 
up exim for outgoing mails. and hopefully, will be done with it soon.

in the meantime, i tried my hand at fetchmail. i already can do 
fetchmail -c without error.

now, someone tell me,

1.    how do i run fetchmail? as a daemon or what?

2.    can i ask fetchmail to download only headers and delete unwanted 
headers off the server only?

3.    after fetchmail fetches mail, where will it put it?

4.    are there any easy to configure utilities that will segregate mail 
finally downloaded?

4.    which software do i use to read the mail fetched by fetchmail? can 
i use mozilla?

5.    any other stuff that might be useful/ interesting etc.

thanx in advance
