From your home page:

"If your email address ends with hotmail.com and you wish to contact
me you will have to find an anternative method. I have set my mail
program to reject any mails coming from hotmail.com together with
several other domains. This is because the people who administer those
domains do not care how they are used, and I am fed up with getting
many hundreds of spam emails inviting me to subscribe to sites
promoting child pornography, increase the length of my male member and
increase my bra size, amongst lots of others."

Is one permitted a wry smile?

Another smile at the humour.


However, veering a long way off-topic for u.r.m.r....

Using the reply domain as a means to filter incoming email isn't very
effective. Spammers just fake the reply addresses, they don't necessarily
use the servers/relays on the domains they fake. If you're going to filter
out a domain, you need to analyse the path the mail used, and even that is
not necessarily going to help.

If bothered by spammers, and your ISP doesn't do mail filtering for you,
then get a decent filtering tool. I use Mailwasher (in addition to ISP
hosted tools), and have done for years. I think two bits of Spam reached my
mailbox in the last year, though lots was blocked on the way through (100's
per month by my ISP, and many 10's by Mailwasher).


Two illustrations of why simple domain blocking fails:
1) there are upwards of 20/day emails bounced back to the 2mm.org.uk domain
(which I manage) which originate from random spammers. NONE of those went
throught the 2mm.org.uk domain mail server on their original path. Its my
guess that those bounced back are only a small fraction of the fakes sent.
2) my domestic email address is on ISP-1. But, I use ISP-2 for network
access, so my outbound email goes throught the mail servers of ISP-2,
nowhere near ISP-1. So, just looking to match the servers to ISPs isn't
effective.
