SocketLabs is an SMTP relay service.

=== Postfix Integration ===

Create a passwords file at ''/etc/postfix/relay_auth'':

<code>
smtp.socketlabs.com smtp9999:MyPassword
</code>

Set permissions and build hash:

<code>
chmod 600 /etc/postfix/relay_auth
postmap relay_auth
</code>

Update ''main.cf'':

<code>
relayhost = smtp.socketlabs.com
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/relay_auth
</code>

Finally, restart Postfix

<code>
/etc/init.d/postfix restart
</code>
