 The Postmark gem is compatible with [ActionMailer attachments API](http://api.rubyonrails.org/classes/ActionMailer/Base.html#method-i-attachments). It allows you to specify the name, content-type and other attributes for your attachments.
 
 The legacy `:postmark_attachments` attribute is *no longer supported* on Rails 3.2.13 and above.
