Contributed by grey on from the DIY postfix improvements dept.
Since OpenBSD ships with an older version of Postfix, I added the web form and cgi processing necessary to add black white and graylisting to the mail delivery system and modified my custom filter script to request that the recipient vouch for suspicious senders. A brief explanation and the code that does it is available here.
Readers should also make note of Postgrey available in ports. Additionally, the ports tree has relatively up to date Postfix snapshots. And of course, there have been other greylisting stories mentioned previously for different MTA's.

I don't think it's Tunisian Muscular Dystrophy Association...
but do you mean Target Management and Development Application or Theory/Modeling & Data Analysis?
Thanks,

I agree that it is awful when applied to individuals though.

Three posts to his mailing list, three challenges.
That's worse than people blocking dial-ups and not offering v6.

spamd can protect any mta. You could even run spamd, then let successful connects pipe through to a separate exchange server. Why reinvent the wheel?

Pretty soon, we're going to have two major LDAP servers which are Free Software. The first is, of course, OpenLDAP. The second is the Apache Directory Server. Again, a good thing.
Multiple minds/groups have always been better about coming up with efficient solutions. That's how science and technology advance; more than one idea comes up, and the best idea--for that task--tends to get used more often. What's wrong with that?

Because spamd a) has been audited, b) is efficient, and c) requires no action by the sender. Not so for the proposed code.
