Sorry for OT, but I wanna install spam-protection tool based on
confirmation email request (somebody send me email, my tool delay that
email and automatically reply requesting confirmation, he confirm, my tool
receive that confirmation and: 1) add his email to while-list; 2) deliver
his initial email to my mailbox). I'm aware about several such tools, but
I'm not sure how they handle incoming emails from other robots - like mail
lists, or some news subscriptions and notifications from websites.
I just don't wanna put myself in position like other people who spam
maillists I read with senseless messages from their tools like
autoresponders or so...
Can anybody recommend me tool which is able to correctly handle these cases?
To be honest, I don't see a way to realize this feature... :(
Ability to protect all accounts at our email domain is good to have, but
personal-only tool is acceptable too. (I use qmail, if this is important.)
