Scam-backscatter is a milter that prevents
backscatter on mail servers which don't host
mailboxes locally. It validates mailboxes by
verifying the recipient addresses hosted on a
different mail server.

Scam-backscatter now supports multiple backend
SMTP servers. The mailertable can be used for the
domain and backend SMTP server mappings. The
BackSMTPServer setting accepts a hostname or an IP
address. Timeouts are configurable. BackSkipVerify
skips recipient address verification for
connections from specific hosts. Additional
logging has been added to diagnose backend SMTP
failures.
A bug where the configuration file required a BackAddrDomain when the ALLDOMAINS feature is enabled has been fixed. This version contains enhancements for better performance on high volume mail servers.
The list of recipient addresses is now saved and loaded at startup into the cache. A BITBUCKET feature has been added to silently delete recipient addresses. This release contains a fix for a memory leak in the SMTP connection.
