Setting up mail on an RPi to an SMTP host

Here a short description how I set up my RPi to send mail, usually sent to the users mbox to an SMTP server.

Installation requirements

Additional to the default Raspbian image I've installed these additional packages:

sudo apt-get update
sudo apt-get install ssmtp mailutils

SMTP Server settings

I've configured my RPi to talk to my ALFAHOSTING mailboxes:

Create a mailbox on ALFAHOSTING
Set name of the mail account to <<This email address is being protected from spambots. You need JavaScript enabled to view it.>>

RPi settings

/etc/ssmtp/ssmtp.conf

# Make this empty to disable rewriting.

# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
mailhub=<<mydomain.com>>

# security enabled
