(ranting a bit)
If "authorities" really wanted to fight spam, they could ban it very
effectively. The originator can be traced even on dynamic IPs. If they
wanted, they could get at them and fine or imprison them as the courts
decided. I must be dreaming...

Right.

Tiscali Spain, for instance, did not have rDNS for clients. They are out
of business, they passed their network and clients to Wanadoo" (France
Telecom). I don't know how they are handling it now.
But it is typical here not been able to set up rDNS properly: we get an IP
based name, even for static, business IPs.

Currently, I do not need a "real" mail server. I only send, but I like to
learn things and do them as best as possible. Ie, let's say that I
"practice" or train myself.
