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

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 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.
