NAT rule for email notifications

Question

I am having trouble sending email notifications from XG210 (SFOS 18.0.1 MR-1-Build396) the senders IP address is showing as the IP address of the interface it is sent from (PPPoE) so they may be rejected or junked by mail server (Microsoft365). 
 
 How can I add a NAT rule for email notifications to alter the senders IP? Assuming this is what I need to do to fix my issue.

Hi Bill Addison 
 Thank you for reaching out to the Community! 
 Did you try adding NAT rule for the system generated traffic? 
 Check out the following KBA for more info: Sophos XG Firewall: How to NAT Sophos Firewall generated traffic . 
 PS: you can also change the source IP address with the static route for the destination email server IP address. 
 Thanks,
