[gentoo-user] Can I send email under linux terminal?

[Lavender]

Actually the subject is not correct . The emails
I sent before were writtern on a web page , not on 
linux system , because I haven't install a KDE
desktop which means I only can work under linux
terminal.
So whenever I want to write a email I have to reboot
my computer and boot the windows system. I'm thinking that
if I can send or receive mails just under terminal, no
need web pages or windows. Also at the same time could
I send mails though the mail server what I use right now under
terminal?
