FROM_EMAIL does not accept e-mail name?
Despite setting up the env variable:
FROM_MAIL=2016\ Budapest\ Degrowth\ Conference\ Call\ \<email@example.com\>
It nevertheless stays with the firstname.lastname@example.org
It seems that he's not able to accept a composed address with the name. Changes in the app only work/are applied if only an e-mail address is there. The problem may be in dokku-alt or in the ruby code itself, so I leave this for @almereyda and @ponder to assess.
It's not critical, but it looks not nice to be getting a mail without a "known" sender name.
