Hi Folks
Unrelated to above McColo etc.
A while ago -
I used to get > 1,500 / day on one account,
and about 800 / day on another.
All incoming were to support addresses
published on client's websites.
Also to another set of dedicated traceable addresses from back in '94.
Seemingly addresses were collated to a database,
then distributed amongst the spammers.
For anyone still experiencing spam -
Popcorn email client is a wonderful tool,
allowing you to optionally download the headers only,
and delete unwanted spam directly from the server.
N.B.
It's no longer actively supported, updated or developed.
