Allow option to configure JIRA "mention" e-mails to come from JIRA's address, not from the individual sender.

This was originally filed as a support request here: https://support.atlassian.com/browse/JST-38574 ; but they directed me that it was a feature improvement request and thus to come here.

Hi,

Our JIRA e-mail integration is working fine (all of the 'watched' issue notifications and such), and the e-mails come from jira@themis.atlassian.net, so all responses automatically go back into JIRA (posted to the issue as comments). This is all correct.

However, "mention" notification e-mails come from the user that executed the mention, which makes e-mail replies go directly back to that user, rather than back to JIRA. This is not desirable behaviour for us – we would rather that "mention" notification e-mails also come from jira@themis.atlassian.net, so that responses go back to the ticket rather than to the individual user.

Thanks.

In sum, I can easily see arguments for both sides of this (i.e. send from the executing user e-mail address vs. send from JIRA's system address). What I am suggesting is an option that allows you to select one or the other according to your individual use case.

In our case, we very much want to keep all of the communication about an issue within JIRA, so that there is a central repository of all information about the issue – rather than having it scattered around e-mail inboxes.

Obviously we can work around this by never replying to a "mention" e-mail, but it'd be much nicer if the "mention" e-mail could be replied to and the result was appended to the JIRA issue as a comment.

Thanks!
