Hey, we currently experience the following problem:

1. Someone tries to forward a mail to one of our user-defined mails for incoming mails.  
Now two things can happen:

2. a) This mail never reaches the inbox of the group. It is shown under `/admin/email/received` but not linked to a conversation. When I try to recover the mail via the [Data Explorer](https://meta.discourse.org/t/32566?silent=true) (see query below), most of the fields (topic, post, error, cc\_addresses, rejection\_message) are `NULL`. The mail is not shown under `/admin/email/rejected`.

Could you send me the raw email that is failing via PM? We will look into it.

Thanks for providing a sample email.  
This should be fixed by

Thank you!  
We tested it again and can confirm that the problem did not occur anymore.
