We don't do this explicitly for POP3, but we do use traffic shaping at the
border infront of our POP3 (and many other) service so that all connections
gets some logic applied.

As such it is a side effect of general traffic shaping we do as described in
the LARTC HOWTO on a Linux box between our email servers and the outside
world. I'm not convinced we apply any traffic balancing to specific POP3
sessions, but it would be easy enough for us to ensure a SFQ QDISC is applied
should it ever become an issue.

Note with this sort of traffic shaping you can only meaningfully shape
outgoing traffic (our shaping is mostly for limiting webservers hosted here),
and it may well not be the sort of thing you want to achieve. And it may well
be too slow to meaningfully limit POP3 sessions with broadband customers.
