Q: I need to send emails with dynamic From name which might depend on the content of Jira issue.
A: There's Raley helper called $jirassimo.customEmailFrom($value) which you will need to use in message template. It can be passed a static or dynamic value as in examples below:
$jirassimo.customEmailFrom("Joe Dou")Will set outgoing email From field to "Joe Dou"
$jirassimo.customEmailFrom($issue.fields.assignee.displayName)
Will evaluate the value of current issue assignee name and use it in email From field
