> \<19\>Nov 25 19:11:29 receive-mail[160]: Failed to POST the e-mail to [https://inbound.thesite.org/admin/email/handle\_mail:](https://inbound.thesite.org/admin/email/handle_mail:) hostname “[inbound.thesite.org](http://inbound.thesite.org)” does not match the server certificate (OpenSSL::SSL::SSLError)

Did you rebuild both the mail and app containers? I think the easy solution is to remove the stuff that tries to give the mail receiver a certificate. Does the cert work for the site?

If the Discourse site is not at `inbound.thesite.org` that’s the problem. The idea is that the hostname of both the Discourse site and the mail receiver will be the same. You’ll need to find [Setting up Let’s Encrypt with Multiple Domains](https://meta.discourse.org/t/setting-up-let-s-encrypt-with-multiple-domains/56685) to fix that.

This is rather beyond the intended scope of the mail-receiver howto. If this isn’t enough to get you on track and you have a budget, feel free to contact me.
