There's been some permission separation in many mail systems over the
last many years. I wonder if this is the case for you here. Is it
acceptable to you just to use sudo for this? Alternatively, you could
write a custom setuid program that just does the appropriate setuid
and execs mailq. That's a very short C program and doesn't open a
very large security hole, especially if it first checks that it is
running as you.
