There are a number of Linux e-mail agents - postfix, sendmail, exim (insecure) and qmail (dead).
# Programs
> sudo apt-get install postfix mailutils
This will register your domain in the /etc/postfix/main.cf file.
# Internal Mail
> sendmail -t roach-1
Write a message and stop composition with Ctrl+D.
The mail is kept in /var/mail/ and you can read it with:
> mail
# Aliases
Aliases are groups of mail recipients. The lists are kept under /etc/aliases.
`crew: matthewlynas@gmail.com,ghost,danial@yahoo.com`
Update the list of aliases from this with:
> sudo newaliases
Then you can:
> sendmail -t crew
... and send to the whole crew.
View pending e-mails using:
> mailq
