[Dovecot] Overriding inbox= in userdb extra fields

[Bret Martin]

Hello,

I'm trying to set up an alternate user with a different inbox using passwd-file and userdb extra fields and the extra field settings don't seem to be taking effect. I've used auth_debug and mail_debug and I'm unclear how I can further troubleshoot this.

Is it possible to have inbox=yes in one namespace globally and then override this for one user by setting inbox=no for that namespace and then inbox=yes for another?

My doveconf -n is below. I would like to have inbox=yes for the inbox namespace, inbox=no for the virtual namespace, and then be able to invert these for selected users using userdb extra fields. My attempt at doing this so far looks like

bam-ios:[REDACTED]:500:500::/home/bam::user=bam namespace/inbox/inbox=no namespace/virtual/inbox=yes

Changing the user with user= seems to work fine, but the inbox= changes don't. Here is some relevant log data.

I also tried not having inbox=yes anywhere in the global configurations, but then I get

Aug  2 11:52:22 new-miranda dovecot: imap(bam): Error: user bam: Initialization failed: namespace configuration error: inbox=yes namespace missing

I'm having great luck with the virtual plugin, but I only want to use it for the inbox on some clients. Any ideas on why my inbox=yes/no overrides aren't taking effect?

Thanks,
