We are currently running Discourse with a multisite setup, and we plan to use the Mail Receiver for email handling. I have a question about the configuration:
Is it possible to configure a single Mail Receiver container to handle incoming emails for all forums in the multisite setup?
I want to ensure that the incoming emails are correctly routed to the appropriate forum based on their domain. Has anyone configured Mail Receiver in a similar setup?
Any guidance, examples, or best practices would be greatly appreciated!

It might be sufficient to adapt this function for multisite:

Thanks for sharing this , but what about the API key how will the mail receiver handle this ?

A hacky way would be to use the same API key on every instance.

Sounds crazy but I can give it a try!

I just did something similar which is working

Thank you so much @denvergeeks for sharing this with me but I have some questions:-
1. Have you installed Postfix on your server first?
2. According to your docs I will need to create a mail receiver container for each forum right?
3. You map the domain to its corresponding forum using the transport map.
4. I see that you have made some changes to the volume mounts too.

Yes, all correct.

Thanks for the confirmation, but can you explain why did you add additional volume because I see both are even different from the default one

It is because of [this section](https://meta.discourse.org/t/configure-direct-delivery-incoming-email-for-self-hosted-sites-with-mail-receiver/49487#block-unwanted-domains-from-sending-to-you-8)… to make available the functionality for blocking certain domains.

Greate, one last question .
Should I create a new path for each mail receiver for example I have about 10 forums so I will need to create new volume for each one od them like this
```plaintext
Default forum:
- volumes:
host: /var/discourse/shared/mail-receiver/postfix-spool
guest: /var/spool/postfix
First forum:
- volumes:
host: /var/discourse/shared/mail-receiver-1/postfix-spool
guest: /var/spool/postfix
Second forum:
- volumes:
host: /var/discourse/shared/mail-receiver2/postfix-spool
guest: /var/spool/postfix
```

Hi @denvergeeks
Thanks to your support, I’ve gained a much clearer understanding of how to proceed. I admire the way you generously share your knowledge, and I’m grateful to be part of such a collaborative community it’s working now.
I do have a quick follow-up question: Is there any additional configuration or best practices you’d recommend for enhancing security in this setup?
Thanks again for your support—it means a lot to me!
Looking forward to hearing from you.

Not that I know of but, I agree with you, that is the next question for which I hope we’ll get some guidance from the community!
Great work! I really appreciate your postings about your progress and results as well - it is a really nice validation and reward for my efforts in sharing!
