I'm not sure, because I haven't noticed  what's opened, when limits where
reached.
If Maidirs are the case, _dovecot user certainly doesn't have rights to read
Maildir/inbox. It's all vmail:vmail with 600 permissions on files. Initially
dovecot is running as root. I'm sure it's dropping privileges when possible,
but reading Maildirs is probably not the case.
If it's root, root is daemon class. That's why I removed dovecot class.
Looks to me, that _dovecot processes are there for authentication. Not sure
though.
