====== Forwarding Email Setup ======

Assuming you already have a full email server (either hosted by you or you are using some third party service), you will need your **internal** server (the home server) to be able to send emails. This is true even if you host your email server, because as i say [[email:start|here]], you cannot self-host a real email server on your home server.

The following must be performed on your internal server.

The Gentoo default **mail-mta/nullmailer** package is more than enough. It should be already installed, otherwise emerge it:

<code bash>
emerge mail-mta/nullmailer
</code>

===== Configuration =====

I assume you already have a mail domain somewhere linked to your **@mydomain.com**, and you have your own address as **myself@mydomain.com** and you created a specific mailbox called **home@mydomain.com** to manage any email sent from services.

All the following files need to be under **/etc/nullmailer**:
<file - adminaddr>
myself@mydomain.com
</file>

<file - defaultdomain>
mydomain.com
</file>

<file - defaulthost>
mail
</file>

<file - me>
mail
</file>

<file - remotes>
mail.mydomain.com smtp port=587 user=home@mydomain.com pass=**** starttls
</file>

===== Usage =====

Try it from the command line:
<code bash>
(echo "Subject: test email"; echo "Hi! my nullmailer works...") | sendmail -F "Me Myself" -f myself@mydomain.com destination@otherdomain.de
