Summary: DKIM plugin - verify fails when given DOS-style line
endings
Product: Spamassassin
Version: 3.1.7
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P5
Component: Plugins
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I've discovered the DKIM plugin has a problem where messages with DKIM
signatures will fail to verify if you pass it to SpamAssassin with DOS-style
line endings. The same message will verify if you change to Unix-style line
endings. (This applies to a Unix-like platform... I don't know what happens if
on Windows.)
It seems to be a problem with the DKIM plugin for SpamAssassin, because the
dkimverify script that comes with the Mail::DKIM CPAN module does not have this
problem.
I'll attach a sample that can be used to check.
spamc -y < dkim_msg_dos.txt
DATE_IN_FUTURE_96_XX,DKIM_SIGNED,UNPARSEABLE_RELAY
spamc -y < dkim_msg_unix.txt
DATE_IN_FUTURE_96_XX,DKIM_SIGNED,DKIM_VERIFIED,UNPARSEABLE_RELAY
I have a patch to Plugin::DKIM that corrects this behavior,
which I'll also attach.
