Hello all. I am looking to install a community service consisting of XMPP server and Email server for free. This is planned to be a public service, not charging anyone anything so I cannot afford to use the money on iRedMail-Pro. Some money would be OK but not list price. So what I am looking at is basically a self-service solution for iRedMail user creation. It should be web-based, with spam proteciton and preferrably some kind of email activation (outside iRedMail). Features need to be at minumum:

- User registration and activation (with captcha?)
- User password recovery - self service
- User deletion

The solution could be PHP based, wordpress plugin (or something similar). I think I want to use Debian 10 + mariadb backend, but I could opt for LDAP backend. My XMPP server of choice is Ejabberd but I could use Prosody as-well. So I guess I am looking for some creative ideas. Since I cannot afford the Pro version, is there some opensource project to enable self-service user management? I think I could quite easily get ejabberd to authenticate to the same DB as iRedMail (or LDAP backend).
