Set domain while sending email #54

Is it possible to change the domain when sending email?

+1. According to Mailgun guides, it's better to send transactional e-mails (reset password, billing statements, etc.) and marketing e-mails (SPAM) through different domains/subdomains. We'd like to start sending e-mails from multiple domains, and support for dynamic domains would be crucial. My proposals:

A convenient option. If From is set to blah@abc.def.com, Mailgun domain is set to abc.def.com and /v3/abc.def.com end-point is used.

config.mailgun_settings[:domain] = :auto

A flexible option. Do it yourself in run-time.

config.mailgun_settings[:domain] = proc do |message|
  # Some code here that returns the domain used to send this very e-mail.
  # The object provided lets me access From, Subject, body etc.
end

Although these are two different options, both would use the same mechanism internally. If :domain is set to :auto, the code runs its default proc that takes out the domain from the From field.
