Question

I have MailInContrib running and working for messages with no attachments. For messages with attachements, the attachment is appended to the message as text instead of being attached to the TWiki topic. I get the following output from running mailincron:

aimsnet:/home/httpd/twiki/bin# ../tools/mailincron
Received mail from Chris Purves <pchris@****.com> for Sandbox.TestMail
[Thu Aug 23 14:29:18 2007] mailincron: Use of uninitialized value in pattern match (m//) at /usr/share/perl5/Email/MIME/ContentType.pm line 24.

Received mail from Chris Purves <pchris@****.com> for Sandbox.TestMail
aimsnet:/home/httpd/twiki/bin#

It appears to me that the MIME type is not identified and so it is not treated as an attachment.

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

From the error messages above, it looks like your attachments may have no content type associated with them, which is banjaxing the Email::MIME module. It would help to see the full text (including headers!) of a mail with attachments that failed. Note that if Content-Disposition is inline, I would expect the attachment to be included inline.

I sent the same e-mail from the same browser to a different account in order to get the full text:

From running with debug option:

It looks like it thinks the document type is .doc when it is .png.

Success! I was able to resolve the problem by replacing the following perl modules packaged by Debian with CPAN modules:

• libemail-mime-perl 1.857
• libemail-mime-contenttype-perl 1.01
• libemail-mime-encodings-perl 1.3
• libmime-types-perl 1.18

• Email::MIME Version 1.860
• Email::MIME::ContentType Version 1.014
• Email::MIME::Encodings Version 1.311
• MIME::Types Version 1.20

I don't know out of those four, which was the culprit, but I have tested with .png and .doc attachements and they are properly identified and saved with no errors reported. The Debian packages did not require test::pod, but the CPAN modules did. Perhaps that is what was missing the first time around.
