after changing the IP address range of appliance
ie. from 192.168.1.x to 192.168.20.x - emails are not getting to the Mail server
I changed the target mail server entry in the Transport section

I can release messages manually to different email address

How can check why its not working
or
do I need to re-install or re-run initial config ?

Is anything showing up in the mail log?

/var/log/maillog

Might give us a clue as to what is happening...

I don't know what mail server you are using but we use MS Exchange at my office. I had also changed the IP address of the EFA at one point and mail stopped making it to Exchange. In the Exchange console, I forgot I had to change the IP address from the old IP to my new IP under Local SMTP Relay Properties of the Hub Transport. Once I did that, my Exchange server was once again receving mail passed through the EFA.

For good measure you may also want to check the EFA's DNS records to ensure they are accurate: And make sure you can dig the mx records of your domain name:
