Would it be possible to specify an alternative mail_executable that wraps the imap/pop processes?

I.e. something like:

protocol imap { mail_executable = cgroup_wrapper.sh }

cgroup_wrapper.sh:
#!/bin/sh
echo $$ > /cgroup/foo/bar/tasks
exec /usr/libexec/dovecot/imap $*

Is the privileges dropped before mail_executable is called, or is it done in the mail_executable itself?

Cheers
