spam fighting email?

[NameTower]

you know the ones where you get a link and need to confirm by entering some sort of image verification, where are some services like that.
Thanks.

Can't confirm but I think the programme called Spam Inspector does this - free trial:-http://www.giantcompany.com/(tl4se055lsprbdz1b00jerj3)/default.aspx?PID=A22227

why do you call that a spam fighting email? That is really meant to be prevent scripts. For spam isn't just sending a link to a mail box that need to be clicked on to activate enough?


Edit: I rethought what you may be looking for, and that is a program that puts mail on hold till a challenge response it met, and you want the challenge to be a graphic for the human to read?

 

[Mr Webname]

If the email arrives and is "unknown" it places it in quarantine and sends a return email that requires a human confirmation. No human confirmation within a set time period and it is deleted - if it is confirmed then it passes to your inbox.

yeah, I was thinking of the web forms that let you register at first, relized what was wanted and updated my message at the same time you corrected my thinking also !

Challenge-response has a major flaw...how do two people, both using challenge-response ever make contact with each other?

1. Person A sends Email to Person B...

2. Person B email service sends a challenge response email to Person A...

3. Person A email service responds back with a challenge-response email to Person B...

4. Repeat...

One possible solution is have Person A's email system keep track of recently sent email addresses and allow challenge-responses through from those email addresses. Seems like the solution...well, except until spammers send out spam that appears to be valid challenge-responses...eventually folks don't know a legitimate challenge response email from a forged one.

Email is becoming more useless by the day...perhaps SPF http://spf.pobox.com/ and the proposed subscriber supported (~2K per year) .mail TLD will truly curtail spam.

Check out http://www.mailblocks.com/

There is a "Pending" folder which holds email waiting for the challenge process.

I think the latest CPanel has this mail feature.

And this "pending" folder is probably choke full of spam too...how can tell a valid challenge response email from a forged one?...think about that a little before replying...the answer isn't as simple as one might hope.

Thanks,
I think I will be using mailBlocks.

Thanks,

I used mailblocks over a year ago, and my quanrantine box just became unbelievably hard to check through as all the spam just piled up. The reason why you need to check is because a lot of legit mail is computer generated and you won't get a response.

I've since settled for the Mailwasher and Norton Anti-Spam combo. If Mailwasher doesn't take them out, Norton just whacks them between the eyes when those spammies try worming into my Inbox.

The feature referred to is BoxTrapper and comes in Cpanel Pro version. Known as the 'challenge/response method' it will either help to cut down on Spam messages, or clog up the server mail queue from spammers using phony addresses.
