Summary: Add SPF_(HELO_)NEUTRAL test to SPF plugin
Product: Spamassassin
Version: unspecified
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P5
Component: Rules
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
This rule doesn't consider the "neutral" reply for SPF queries. While it may be
a definite no-no to outright reject e-mail in this case, I have found during the
past weeks that it is a strong indication that a message is indeed spam.
Probably even stronger than "softfail".
Take for instance the Amazon.com (an many others) SPF record. All IP's for
207.171.160.0/19 will "pass", while others will yield a "neutral" response.
Spammers will quickly pick this up to prevent additional scoring.
