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.
