Why are e-mails sending from @discoursemail.com?

According to mailserver logs, test E-mails sent from Discourse are sending from @discoursemail.com which is preventing DKIM signing because of the domain mismatch.

Why is it doing this and how can it be fixed?

discoursemail.com is used for mails sent by our discourse.org hosted forums. You should not be using it on a self-hosted forum. What have you set for your notification email site setting?


Thanks I changed that setting and that fixed it. Reply’s via E-mail isn’t enabled but it’s attaching the reply-to header anyway, apparently?
