Doesn't work with parentheses in the "FROM:" display name

Sending an email with the following from email address results in a 400 Bad Request:
Christoph (Derp.com) <christoph@derp.com>

I tested the same with mailgun-ruby and it works there, so it's not the mailgun API not supporting it.

+1 Same problem!

found solution?

is there really no way to fix that. I am pretty sure problem lies in rails_message[:from].formatted

ok solved it

if you set it like this it works: default from: "My Company Name <support@company.com>"
i did this in application_mailer.rb

got hint from rails guides on actionmailer
