defining outgoing interface for System Notification mails?

Question

I think I need to SNAT this but maybe there is an other option to define from which interface the Firwall sends it's alert/notification mails and Email Backups? 
 We noticed the mails the Firewall sends internally are now coming from different Firewall source IPs some times and then these mails are bounced by our Mail system. 
 The firewall is not configured for mail protection.

Hi LHerzog , 
 Thank you for reaching out to the community, 
 The ability to select a specific interface for email notification is great idea, but this would be a Feature Request; I'd recommend you reach out to your Account Manager, Sales Engineer, or Sales Representative so that they can enter this request into our system. You can also log a support case so that our support representative can help link that FR to the account. 
 Additionally , you can use the in-product feedback in the Sophos Firewall located in the Top Menu Bar.
