Postmark::InvalidMessageError when attempting to send mail
postmark, ruby-on-rails
Solution
SPF and DKIM are recommended, not required. However, sender signature is required (as stated in the documentation).
Are you sure you are using the same From address as the one used to create the sender signature? This can happen if you are using different email.
Problem
I use Rails 3 + Postmark-Rails. At first, I created account on postmarkapp.com to get my api key. I Activated my signature by email link [for example, "vitalyp@dot.com"] -- After that, I added this to application.rb ``` config.action_mailer.delivery_method = :postmark config.action_mailer.postmark_settings = { :api_key => "fdcb..." } ``` I use this method to send emails: ``` class UserMailer < ActionMailer::Base default :from => "vitalyp@dot.com" def do_my_mail(to, subj) mail(:to => to, :subject => subj) end ``` I get this error: ``` Postmark::InvalidMessageError Sender signature not defined for From address. ``` Any ideas?
