[Bug 6465] New: RCVD_ILLEGAL_IP incorrectly matches 169.254.0.0/16
https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6465
Summary: RCVD_ILLEGAL_IP incorrectly matches 169.254.0.0/16
Product: Spamassassin
Version: 3.3.1
Platform: PC
OS/Version: FreeBSD
Status: NEW
Severity: major
Priority: P2
Component: Rules
AssignedTo: dev@spamassassin.apache.org
ReportedBy: dan@more.net
At some point 169.254.0.0/16 was added to the RCVD_ILLEGAL_IP rule. It was not
there on May 20, 2010 (version 3.3.0) but it is there now.
According to IANA, 169.254.0.0/16 is the "link local" block. It is allocated
for communication between hosts on a single link. I'm not sure that makes it
invalid.
I've had two false positives reported to me this week. It appears that
Microsoft Exchange clusters use this range. Here is a (sanitized) received
header from a non-spam test message sent to me that matched the rule:
Received: from email04.university.edu ([169.254.1.144]) by
NHUB02.university.edu ([209.xxx.xxx.xxx]) with mapi; Tue, 20 Jul 2010

Bug 6460 is about named hosts that start with a number matching this rule by
accident. This is about the 169.254 range which is being matched on purpose.
I do not believe they are duplicates, except that they both cause false
positives.

+1 for the fix.
I have encountered this bug too. 169.254.0.0 should be treated like an RFC 1918
address range - its purpose is similar though the way addresses are allocated
is different.

Huh, fixing this would be trivial. After all, /169\.254/ is mentioned
explicitly in the alternation, so it just would have to be removed.
