Description:

Maildrop is a combination of a mail filter/mail delivery agent.
Maildrop reads the message to be delivered to your mailbox, optionally
reads instructions from a file how to filter incoming mail, then based
on these instructions may deliver mail to an alternate mailbox, or
forward it, instead of dropping the message into your mailbox.

Maildrop uses a structured, real, meta-programming language in order
to define filtering instructions. Its basic features are fast and
efficient. At sites which carry a light load, the more advanced,
CPU-demanding, features can be used to build very sophisticated mail
filters. Maildrop deployments have been reported at sites that support
as many as 30,000 mailboxes.

This version is compiled with support for DB database files.
