Here's what I do on my Sun workstations and my linux boxen when I need to use 
CLI mail clients (ok, I only use pine and mailer):

edit /etc/mail/sendmail.cf and set DMmydomain.com 

This way sendmail is masq'ing as my domain.

(restart sendmail)

open up pine, set my config stuff to have my return address be me@mydomain.com.

install fetchmail

make a sweet ~/.fetchmailrc file that pulls my mail from all my pop3/imap 
sources.  make sure that fetchmail knows that I want my mail to go to MY local 
mail account, so be sure to include a "is [insert local username here]" is in 
there for each account.

put fetchmail in my crontab:

crontab -e

5 * * * * fetchmail

make a sweet ~/.procmailrc file to sort my mail into folders

make a sweet ~/.signature file for when I want to email someone and impress them 
with my knowledge of silly popular unix jokes.  (lol)


This is just random nullfeed out of my brain.  Hey, it's 23:40, whatcha expect?  
*grin*
