Challenge/Response spam filter

[glAdmin]

Hi,

I would like to enable a challenge-response type spam filter on some email addresses, so that every new sender receives a challenge to be resolved in order to be considered trustworthy and his message arrive in my inbox.

Is it possible to configure something like this with Direct Admin Web ?

Thank you.

Sending mail is a complete other system than websites. Mailcaptcha's are non-existing.
You can only use captcha's for example on mail forms on a website.

However, I have seen some other verification system in the past, don't remember how it's called. But in that case somebody has to send a mail, then the receiver gets some notice and has to approve the sender, after that the sender can send mail.

You have to look for e-mail verification solutions but I don't know if this can be implemented in Exim.
Maybe @Ohm J or @mxroute know about this.

To be more clear, I would like to see implemented in DirectAdmin what is called BoxTrapper in cPanel ...

See details on this page.

I have seen interest from other users of this forum to have this feature in DirectAdmin ...
