Summary: check_for_from_dns doesn't like two From lines in header
Product: Spamassassin
Version: 2.63
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Rules (Eval Tests)
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Investigating a SpamAssassin report with a NO_DNS_FOR_FROM I found strange MX
and A queries in the guilty DNS:
[EMAIL PROTECTED]
Looking carefully at the headers I saw the following (replace xx with nl, just
to protect the existing e-mailaddress :-) :
From: [EMAIL PROTECTED]
Message-ID: <[EMAIL PROTECTED]>
Date: Sun, 1 Aug 2004 20:22:42 +0200
X-Priority: 3
X-MSMail-Priority: Normal
X-Mailer: PHP
X-MimeOLE: Produced By phpBB2
From: [EMAIL PROTECTED]
I can now create all kinds off strange e-mails with simular results. The real
bug is of course in phpBB, but I think that SpamAssassin must also check for
bad headers. I haven't tried to include lots of rubish between the two From
lines, but possible this could lead to all kinds of other unwanted behavior...
