I'm sorry to hear that you've had problems with spam filters; like most things 
(and most people), they aren't perfect and they sometimes make mistakes.

I became a postmaster about the time when the practice of signing a document 
stating you would not use network access for commercial purposes was no longer 
being commonly required before one gained network access via DARPAnet, JAnet, 
and such.  My sympathies are very much in agreement with your main point, 
which is that legitimate email should not be blocked by spam filters.

If one sends a message that could not be delivered, an error report (called a 
DSN) is returned, describing the problem.  People sending legitimate email 
know who they've sent mail to, right?  And when they get DSN's, as you most 
probably did, you talk to your ISP, etc, etc.

How many bounced messages are you talking about, approximately?  Would you be 
willing to give those individuals a phone call to talk about your message, 
instead, or ask their postmaster to change their spam-filter to let your mail 
through?

[ Because that's basicly what it all comes down to, all of the advocacy for or 
against regulation aside.  FWIW, I block three /16's under 16.0.0.0/8, but 
yours wasn't one of them-- I checked.  Bah...I'm getting 1000+ dictionary 
scans from DSL pools in .br a day. ]
