Back to search · Not supplied

Description

greyscanner compliments OpenBSD spamd(8) greylisting by applying additional heuristics to greylisted hosts. Additional heuristics include: confirm senders email address is valid, confirm existence of the senders MX or A record in DNS, confirm recipient address(es) is valid, and more. Offending hosts are flagged as 'trapped' in the spamd database.
