Still a bit wrong actually. :) It was Dovecot that was caching the
capabilities. The way it works is:

If you have mail_plugins enabled, Dovecot needs to know what IMAP
capabilities the plugins add. So at startup Dovecot executes imap
process as "dump-capability" user, which loads the plugins and tells
tehe capabilities to master process. This capability string is currently
saved permanently until a restart. If you changed mail_plugins and HUPed
Dovecot, the capabilities still wouldn't change. I guess this could be
thought of as a bug, but it's way too much work to fix. I'm still hoping
that none of this will be necessary with v2.0.
