Its worse than that.

I needed to fake an email fr a friuend who was sitting beside me ta the
time. To send off a large dicument I had hlepned him preprae.

No problem I thought, I can fake his BT email account and send it
through my own SMTP relay.

No chnace. the target systenm rejected it in te grounds that BT email
doesnt get sent from random relays on the internet.

When I used his own domain however it worked perfectly.

The point is that it is now almost unacceptable to use your ISPs SMTP relay.

You have to send via your mail persons SMTP relay.

Last year, visiting my sister in Germany, I could not even connect to a
third party port 25 without adding a whitelist to the ROUTER.

Before the commercialisation of the Internet, there was no point in
sending random emails to people you didn't know.


Apart from malware,  I wonder how many people, like me, simply refuse to
buy anything they have seen advertised on the internet or on TV?

Is there any point in SPAM?

I only have one charity apart from poppy day, that I ever give serious
money to. I bought a charity produt online

Every week since then I was emailed junk promotion for more charity
products. Clicking unsubscribe made no difference. I blacklisted the
domain. I will never contribute to that charity again.
