-q and -M

I notice that only admin users are allowed to use `sendmail -q' to force a
queue run these days (I think this is relatively new behaviour in Exim).
However, any user still seems to be able to achieve much the same effect
by gathering a list of message-ids in the queue (easily done with mailq |
awk) and passing the result as an argument to `sendmail -M'.

This strikes me as a bit inconsistent. I can't think of any reason why
the ability to force a queue run should be a security hazard but the
ability to ask for specific messages to be delivered isn't - but perhaps
I'm missing something.

Any thoughts?
