I am running my own email server software - and it has whats called
Challenge Response.
Basically, when you get an email from someone for the first time, it auto
replies with a link they have to click on, and enter in some text into a box
to authorize themself. They have 2 weeks to enter in the digits or else they
are on the block list.
Once they enter in the number to authorize, the email is sent through to
your inbox (It basically just sits on the server, you don't know it's there
until they auth.)
Also, if you email someone, it automatically puts them on your allow list,
so when they reply they do not need to authorize themself.
It's pretty neat, I would also get about 50 emails a day, now I get zero!

email-/webcrawlers
I totally agree. And I haven't said that this would be 100% bulletproof. I
get about 50 - 60 spam mails per day (maybe not much, but I think it's
enough). And if this is preventing only some of the email spiders to suck
out my email adress from the contact pages, well, why not.
I mean, if you want to have 100% protection - don't have email adresses
on your pages at all. However, I think that it is more important for my
visitors to be able to contact me, than to start a never ending fight
against email spiders.

nice - but don't you think spammers might be able to test for ascii and
convert it for there use?
