Incoming Email - Only first recipient is handled

Parad0x · September 11, 2021, 12:42pm

An old bug has resurfaced because some users didn’t get an important info.
I noticed that the initial report is located unter support and not here under bugs.
@moderators feel free to merge and locate everything here under bug if split/double posts are a problem. Thank you very much.

Summary

An incoming email (via POP3) hat the address from multiple discourse-groups (email-enabled) in the To-Field. Only the first hit is processed. All other groups are not invited to the new topic (

@evantill found the code that handles the incoming mail:

discourse/discourse/blob/7c95b7ceb5a9ab8ed34923f15a076b31f1a1c229/lib/email/receiver.rb#L214

    
      
                         elided: elided,
                         post: post,
                         topic: post.topic,
                         skip_validations: user.staged?,
                         bounce: is_bounce?)
          else
            first_exception = nil
          
          
  destinations.each do |destination|
              begin
                return process_destination(destination, user, body, elided)
              rescue => e
                first_exception ||= e
              end
            end
          
          
  raise first_exception if first_exception
          
          
  # We don't stage new users for emails to reply addresses, exit if user is nil
            raise BadDestinationAddress if user.blank?

I can understand some of the code, but I’m not able to make a qulity pull request.
How can I help to get this fixed? At the moment I have to manually add all recipient groups to the automatic created message for the first recipient-group.
