How to Relay Mail from TWC Home Connections

By | 2016/02/14

If you are like me, you have some Linux machines at home or a workstation which would benefit from relaying mail out for logwatch, owncloud emails, cron errors, or other reasons like perhaps a home mail server. If using Time Warner this is how to relay mail from home without being dropped or marked as spam!


Use this host to relay mail when on a TWC network:

1. First, install postfix

sudo apt-get install postfix

If prompted, select internet site.

2. Next, edit the postfix config file

sudo vim /etc/postfix/

Locate the line which says relayhost = which should be blank by default. Change that to

relayhost =

Save the file.

3. Finally, restart postfix

sudo systemctl restart postfix

Done. Mail will be delivered ok using TWC’s mail relay. No authentication is required if on TWC’s network.
