Providing accounts without email and xmpp

I want to provide few account which have Ldap support for the apps but should not be able to send mails and connect to xmpp.
Somebody have tried this or have fast solution for it ?

Bonjour.

Si j’ai bien compris votre problème, la solution a été donnée par @CaptainSqrt2:

Thanks for the information. But I would like to disable postfix and metronome authentication for some users. I am sure there is no option in Moulinette to do this. I would like to do it manually.

This was for app access but mail and XMPP are not apps :confused:
