For small non-profit organizations, you can pay a one-time fee to 
Habeas and/or Return Path and take part in their "safelist" or 
"bonded sender" programs, and that should significantly help your 
penetration into various sites, not just hotmail.  For example, using 
Habeas improves your spam score by a full 8.0 points with 
SpamAssassin using an out-of-the-box configuration, although 
ReturnPath only improves your spam score by 4.0 points.  Still, 4.0 
points may be enough to take you out of the yellow and into the 
green, and 8.0 points would almost certainly do that.

I think we send too much e-mail for python.org to do this sort of 
thing as a small non-profit (there are daily/monthly/yearly volume 
limits), but we should probably talk to the PSF about an annual 
subscription to their lowest tier of service on these programs, and I 
have contacts at both Habeas and ReturnPath that we can talk to.


We're looking at doing this for my "real" employer, and for one of 
the largest public universities in the world, the safelist price I 
was quoted was less than $10,000.  And we do a *lot* of volume at 
work.  Smaller sites get charged proportionately less.
