I have a mail server with a new address generated per post (or per comment for thread functionality) on a blog i run. People then get to mail their comments. For all reputable mail sites I let things directly through, for everything else I use a spam filter turned to 11 together with a mail-back link for post verification.

I have had zero spam the last 8 years.

The code is ancient and runs on an even older version of lispworks with Auth details hard coded all over the place, so I the time it would take for me to share it would be longer than to rewrite it in some hip language.

Had I been lazy and not as privacy conscious I would have let Gmail do the spam filtering for me.




Have you considered open-sourcing that and posting it on HN? I'd use it.


I have been asked to many times, but it is part of a largish website written in Common Lisp. The codebase is written by me over 3 years with no consideration for modularity. It would be a considerable effort to break it out.

There is nothing technically novel about it. Heck, python even includes an SMTP server in the stdlib. You could.probably write a PoC in a couple of hours.


> so I the time it would take for me to share it would be longer than to rewrite it in some hip language.

I'm reasonably sure the answer to your questions is yes.
