I see one syntactical thing you missed.
You have to define your child queues in your altq declaration. Something
like:
altq on $ext_if priq queue {mail, ssh, web}
Also, after you get the syntax right, unless the maximum bandwidth of your
outside line is the same as the maximum bandwidth of your network card
(does this ever happen?) you're going to want to use the "bandwidth"
keyword in that declaration also, and pick a proper value for it. Picking
the right bandwidth value seems to be an art form that requires a lot of
trial and error and liberal use of "pfctl -vvs queue"
If traffic shaping isn't working and your queues are always empty, then
the number is too high. If the queues are filling up and dropping too
many packets, then either the number is too low or you're just generating
more traffic than you can handle well.
