Hello,
I've 2 mail servers, as test server, with dovecot as backend and setup pop3 and imap connections and NFS. For prevent issues with simultaneous connections I want to setup up Director on the same VM and on the same instance as the backend Dovecot.
I found in the documentation that this configuration is broken, but can work with development, and after research on the internet and on the questions encountered previously as on :
https://dovecot.org/pipermail/dovecot/2015-July/101483.html
https://dovecot.org/pipermail/dovecot/2011-September/130939.html
https://dovecot.org/pipermail/dovecot/2012-June/136535.html
I find it quite unclear if this is really possible with director_proxy_maybe, which according to the changelog, allows this setup to work.
Today I've reached this level with those errors:

sql query :

It seems that Director is working but not adding the "host" extra field when it should, also it's strange that the director_proxy_maybe is unknown.
Is it really possible to configure director on same instance as backend? Is director_proxy_maybe working? Also do you have answers about my problems?
Thanks for advance.
