Summary: Bad content-type circumvents URIBL checks.
Product: Spamassassin
Version: 3.0.3
Platform: All
OS/Version: other
Status: NEW
Severity: normal
Priority: P5
Component: Libraries
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Lately I've been getting lots of spams that have invalid Content-Type headers.
Mail::SpamAssassin::Util::parse_content_type() returns an empty content-type for
these, and as a result, URIBL checks do not happen.
Here is one example:
----09-4[5]-2047-7[3]-082[3]
Content-Type: ;text/plain;
Content-Transfer-Encoding: 7Bit

...
Note that the Content-Type starts with " ;". Its the leading semicolon that
screws things up here. This could probably be fixed in parse_content_type()
pretty easily.
