AOL, for one. You may not think that's a bad thing...

It depends a bit on which ISP you're using and what sort of services
they provide. If you have a fixed IP address then you're more likely to
get away with it (compared to using one of a pool of dynamic addresses,
which may be used by random virus-infected Windows clients). Similarly,
the more "business class" your service, the more likely they are to
accept e-mail from you.

See, for example,

Hope this helps,
