Problems Configuring FreePBX for using external SMTP Server

[embischoff]

Does anyone know how to change the default FROM address when attempting to use an external SMTP server? Right now it is asterisk@phonesystem.xxxx.org. I want it to be just phonesystem@xxxx.org. I’ve tried making changes with Postfix, but I may be doing it in the wrong config file. I have an SMTP server set up on a Windows machine to relay. We are using FreePBX 15.0.16.81.

The previous log’s error were because of a service not started on the SMTP server. This is a more accurate log of the problem:

Assuming oyu have updated all the things inside FreePBX, then you drop to postfix config settings.
The file /etc/postfix/generic is handy here.

root pbx@domain.com
root@localhost pbx@domain.com
root@localhost.localdomain pbx@domain.com
root@freepbx pbx@domain.com
root@freepbx.localdomain pbx@domain.com
asterisk pbx@domain.com
asterisk@localhost pbx@domain.com
asterisk@localhost.localdomain pbx@domain.com
asterisk@freepbx pbx@domain.com
asterisk@freepbx.localdomain pbx@domain.com
asterisk@domain.com pbx@domain.com
vm@asterisk pbx@domain.com
@pbx.domain.com @domain.com

Add a reference (if needed) to main.cf

Run the postmap command to build it.

postmap /etc/postfix/generic

Then restart postfix

systemctl restart postfix
