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 ---

The easiest way is to [Configure direct-delivery incoming email for self-hosted sites](https://meta.discourse.org/t/configure-direct-delivery-incoming-email-for-self-hosted-sites/49487) ---

Hi Jay, and thanks for your reply. I have a 2 stage server. One container for prod system and one for testing. I have nginx in front of both. I am not sure how to control the new mailing container for each instance. What would the way via pop3 and my normal mailserver? ---

Does your mail server accept [sub adressing](https://en.wikipedia.org/wiki/Email_address#Sub-addressing) for your replies@mydomain.tld inbox? ---

Hi Thomas, yes Sub-Addressing is possible. I tested it with bob+forum@mydomain.tld and the mail is received. Whats next? Do i have to change the configurationt to something like bob+%{reply\_key}@mydomain.tld? thx ---

Whatever you configure as your reply address, it has to reach the mailbox your server is polling for incoming messages. replies+something@mydomain.tld should all be forwarded to this address.
