After some researching I ended up with mutt as the easiest mailer to send messages from the command line.
When trying out the syntax I encountered a problem which makes me think there is a file missing in the package.
This is my sample output:
root@svm01:/etc# mutt -s "test05" no-spam@gmail.com -a /nas46/ebook/EN/T/Thomas
\ Harris/The\ Silence\ of\ the\ Lambs\ -\ Thomas\ Harris.mobi < /etc/hosts
sh: /usr/bin/mutt_dotlock: not found
Couldn't lock /root/sent
Could not send the message.
root@svm01:/etc#
The exe-file mutt_dotlock is not included in the package.
Please advise.
