Summary: DATE_IN_FUTURE_96_XX false positives
Product: Spamassassin
Version: 3.2.3
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P3
Component: Rules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I'm seeing common but intermittent false positives from the
DATE_IN_FUTURE_96_XX test, using spamassassin as a milter. Sample headers (and
corresponding sendmail logs) follow (I've masked my email address, everything
else is verbatim). Note that all dates are within about 10 seconds of each
other; I'm in UTC+2, relaying via a server in UTC+8. Any idea what may be
causing this?
Sample headers generating false positive:
