When Pagure sends an email containing a comment (e.g. on an issue) written by a specific Pagure user, the message “From” field is “From: pagure@pagure.io”. But it is not Pagure.io who wrote the message, it is a specific person whose name is known.

The email message “From” field should instead show the person who wrote the comment, e.g. “Ben Finney (bignose) via Pagure.io <pagure@pagure.io>”.

With that value, responses would make sense, discussion threads would make sense in the recipient's email, etc.
