Hello,
I plan to set up a personal mail server on my own domain, but I am worried about spam.
I though about greylisting, but I really want ZERO spam to go into my main account (i will have other multiple accounts for spam, bulk, automated messages, notifications and other shit), so I want something even better.
So I was thinking about following solution:
Alice@alicedomain.com sends email to bob@bobdomain.com
Email server at bobdomain.com puts the email in "Probable SPAM" folder
Email server at bobdomain.com replies with an automated message stating that alice has to do one of 2 things in order for her messages to be accepted into whitelist: A) Reply with special security code (sent in the first reply) B) Click a link included in the reply
After alice does one of these 2 things, her email (Alice@alicedomain.com) is added to bob's server's whitelist and is no longer automatically blocked.
My question is: is there a software package that lets me do something like this ?
( Of course i want to do it on Linux )
