currently all notification mails sent by YouTrack use the email address configured as "Server 'from' email" in the Adminstration settings.
For example the mails generated by YouTrack usually have the following From
header, where 'Jochen Schalanda' is my account's name and 'email@example.com
' is the default email configured in YouTrack:
From: Jochen Schalanda <firstname.lastname@example.org>
Is it possible to have YouTrack use the email address of the user who did the change as it is using the user's name?
