Sophos XG ISP changed and built-in email server to send Backup externally stopped working

Title says it all really!

This morning, the ISP changed (with a new external IP Address) and this evening, the xg backup did not send. 

What do I need to change to work again?


Many thanks in advance.

    If there is a relay host defined, and it is related to the previous ISP change this.

  • In between, I received a quarantined digest of a 'blocked' email!!!

    I believe its because I need to add the new IP address in the SPF settings for domain.

    I'll let you know after the week-end once changed.

    Thank you
