|Subject:||Double ; parsing bug in ParseParams|
I was debugging an issue with our anti-spam setup, and ran into the following "bug" in Mime::Tools. It seems there is an increasing number of mailers out there (eg the mailinglist software of the popular Typo3 CMS) that send "strange" multipart headers. They send something like this: Show quoted text
> X-Mailer: TYPO3 Direct Mail module > X-Priority: 3 > Mime-Version: 1.0 > Content-Type: multipart/alternative;; > boundary="----------part_1_499d36ca96aea"(Notice the double ; between multipart/alternative and the boundary). I couldn't find any specific reference in the RFCs about double-;'s but it seems MIME::Tools fails to parse it correctly. To test this, I wrote a small script: Show quoted text
> #!/usr/bin/perl > # > use MIME::Head; > > my $head = MIME::Head->new->from_file("testmail"); > > print "mimetype: " . $head->mime_type; > print "\n"; > print "boundary: " . $head->multipart_boundary; > print "\n";Expected output would be: Show quoted text
> mimetype: multipart/alternative > boundary: ----------part_1_499d36ca96aeawhile actual output is: Show quoted text
> mimetype: multipart/alternative > boundary:This has been tested with v5.8.8 and MIME::Tools verions 5.420 and 5.427 (installed from CPAN).
