How do I enable email sending on a proServer?

By default, email sending is disabled on the proServers to prevent accidental spamming.

To enable this feature, follow these 4 steps:

1. Do not disable Sendmail in /etc/rc.conf

$ sudo vim /etc/rc.conf
# alternativ steht auch "nano" als Editor zur Verfügung

Condition upon delivery:

# Disable Sendmail by default
sendmail_enable="NONE"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

Option 1 - Send only outgoing emails (remove all other lines):

sendmail_enable="NO"

Option 2 - Send outgoing emails and receive incoming emails (remove all other lines):

sendmail_enable="YES"

2. Prepare the Sendmail configuration

The file /etc/mail/aliases should contain at least the following line:

# root:	me@my.domain

must be enabled and associated with a valid email address. Information about the system—including any failed cron jobs and similar issues—will be sent regularly to this address.

A possible entry might then look like this, for example:

root:	proServer@example.com

3. Set up Sendmail

$ cd /etc/mail
$ sudo make
$ sudo make install

4. Start Sendmail

$ sudo service sendmail start

The following message is normal and simply means that Sendmail only sends mail and does not receive it.

Cannot 'start' sendmail. Set sendmail_enable to YES in /etc/rc.conf or use 'onerestart' instead of 'restart'.

Done. Shipping is now configured and enabled.

Note: As a general rule, you should not change the generic hostname of your virtual proServer. Setting it to "meinedomain.de," for example, because that is the name of your website, will prevent you from sending emails from the proServer to your domain.
