Problems during local JMAP setup regarding HTTP 405 response

[stanimir at audriga.com]

Hello everyone,

I'm currently trying to test a JMAP client library against a locally 
running Cyrus instance.
The issue which I'm experiencing is that when trying to make a JMAP 
request like the one described in the docs here: 
https://www.cyrusimap.org/dev/imap/developer/jmap.html, I'm getting a 
"405 Method Not Allowed" response.

My setup is:
  - OS: Debian Bullseye
  - Cyrus version: 3.2.0-beta3-Debian-3.2.0~beta3-1 (I got the Cyrus as a 
Debian package and managed to get it running)

Here are my .conf files:

     delprune    cmd="/usr/sbin/cyrus expire -E 3"

}

I also ran an OPTIONS request for all paths (with the * operator) on 
port 80 for localhost via telnet, which showed that pretty much all HTTP 
methods are possible (including DAV). However, when running the OPTIONS 
request for the /jmap route, only OPTIONS, GET and HEAD are allowed.

I would be very happy if somebody could offer some insights on this 
issue.
