My problem is:
We have seen that when you use an existing email template on a send results/ send email action on a form, the from email address which is set on the email is not used and instead the email comes from the system mail.
Is it expected behaviour that the responses do not use the templates mail settings? From my belief, it should use each setting from the email.
Interesting catch. In fact the email used as template just loads into the form action. It will not define the custom from email address. That function doesn’t exist (yet) in the form “send results” action.
That would be a feature request. You might add it into the Ideas and Feature Requests - Mautic Forums section or fund some developer support to get it implemented, if thats an important thing for you to have.
