Hi,

I've coded a new greylisting implementation for postfix (based on
postgrey) to toy with auto-whitelisting ideas some months ago. This is
based on postgrey but like gld uses a SQL backend (SQLite, MySQL or
PostgreSQL).

In fact, although I only discovered gld today on this ML archives by
googling around looking for DSPAM/Postfix large install integration
howtos, SQLgrey and gld have many common functionnalities (it seems
there aren't many ways to reduce greylisting delays :-) ).
SQLgrey even had something very close to gld's lightgrey algorithm
implemented some time ago. I decided to remove it due to lack of
interest. Do gld users see benefits from using lightgrey ?
SQLgrey supports a somehow refined lightgreydomain algorithm too (it
combines both mail-based and domain-based auto-whitelisting, switching
to domain-based above a configurable number of senders from the same
domain/IP).

If you're interested in greylisting, have a look at
http://sqlgrey.sourceforge.net
Request for enhancements, bug reports, advices are welcomed.

Best regards,

Lionel.
