I think this is a top feature, I normally use another milter to do this but if
milter-greylist supports it I'll give the other milter the flick.

One feature which would really be useful though, is in addition to controlling
the "number" of messages handled outbound, can you add a feature which can
control the "bandwidth" used by the MTA outbound?

For example, only allow the MTA to consume 100kbps outbound of the link?

I have some clients which would really make use of this, since they share a
broadband connection and when a large emails are sent, the MTA consumes the
outbound bandwidth so much so that other functions (like viewing streams or
videos or youtube etc) die and drop out until the emails are completely sent.

Would this be a function/facility that could be added?
