Improve mail handle to fire events when emails are processed

Mail handler to fire event:

• when email is processed and creates a new issue

• when email is processed and creates a new comment to an issue

Events will be configured in the related Mail Handler Context.
JETI notifications can be set up to notify users when an email is processed.

Recommended procedure:

• Define custom events in JETI (Issue created by email, Issue commented by email)

• Configure JETI templates to use

• Configure JETI notifications to use the new templates for these events
