Asterisk Voicemail to Email solved with Postfix

Editor's Note: Here is a follow-up Asterisk help article from my good friend & VoIP Engineer Matt Birkland at VoiceIP Solutions.

A while back I wrote an article for Asterisk VoIP News about routing loops occurring from misconfigured DNS(or lack there of). My article was about routing loops caused by Asterisk attempting to send mail outside the network when the mail server destination is internal.

To correct this issue the Asterisk PBX needs to define a ‘mail relay’(mail relay) on the internal network. This post will discuss using Postfix as an alternative to Sendmail for this purpose.

The goals of this post:

- explain Asterisk voicemail to email routing loops

- LAB: Install Postfix and configure ’smarthost’ for mail relay

Here is an excerpt from my previous post that explains the nature of the problem:
