How to have mutliple domains on Modoboa with webmail? (sopuli.xyz)

As many have advised against it, I decided to start (almost self-)hosting my mail service.

I have tried with one domain, it has been running fine so far. I have not tested deeply but it works.

I want to host another domain, so I followed this guide which seems mostly still applicable: https://www.linuxbabe.com/mail-server/modoboa-multiple-domains

One thing though, with the current basic modoboa install, after following the steps in this guide, I can go to mail.domain2.com to access the webmail, however it is some kind of redirect and I end up on mail.domain.com. It must be on wsgi level because there is no redirect in nginx? So technically it's still working since it's what's actually under the hood. But would it be possible to stay on mail.domain2.com?

Or maybe I have missed something somewhere, because unlike mentioned in the guide, it seems I have to use mail.domain1.com to set up client IMAP and not mail.domain2.com.

I know this is not a modoboa support community but I am not going to create one (yet) and I am not going to reddit. And I can't open issues in Github. So live with it.

I've not used that software before, but a quick look at the guide makes me wonder if you have a https redirect in the nginx config. If that is hard coded to domain1 it will always redirect to it. Update it on the new config file to point to the right uri if that is the case.

Usually I setup with a single domain for the server, and use that for web mail, IMAP and SMTP certs. That way you don't need to worry about the extra certificates needed for each domain (set your Mx to use the common name of your cert.)

The nginx conf has a https redirect, but I have a separate conf for domain2, and the redirect is correctly going to domain2.
