Hi all,
I was wondering if someone might be able to point me in the right
direction as my searches proved fruitless.
I am looking for a email verification system for postfix, but with a
twist. Not referring to
http://www.postfix.org/ADDRESS_VERIFICATION_README.html
The system that I am looking for should be able to include per user
interaction. What I have in mind how it should work is the following:
- Email enters the system and checks if the sender's email address is
already whitelisted for the recipient of the email.
- If not, a pre-email is sent to the recipient requesting if the sender
is of the email is valid. Perhaps the pre-email would have 2 links
(apache comes into play), or just replying to the MTA with approve or block.
- The sender is then either permanently whitelist/blacklisted for the
recipient/user on the system.
Per user is required as some users might want emails from a
[email protected] and others not.
Normal anti-spam measures should still apply, just this extra automation
so users can handle their own white/blacklisting from within their mail
client without having to log into additional panels etc.
Any advice (or interest!) on such a system would be appreciated.
Best regards,
Keith Williams
