Hi,  
i try using mailing list and mail reply. I have a selfhosted Discourse container. All work well. Emails are received and send. Mails from new Topics are send and received. But if i answer to an email and topic i got:

\*\* **`bad_destination_address`** : none of the email addresses in the `To`, `Cc` and `Bcc` fields matched a configured incoming email address.\*

I tested with different mailsystems. If i use the same host, thunderbird or roundcube shows me the correct recipient address from the forum. But if i reply from gmx it shows me replies+123yxc234. Thats seems to be configured in discourse: replies+%{reply\_key}@mydomain.tld. But this mailaddress didnt exists. How can i handle this?  
thx
