Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

rfc-822 type attachment (.msg) file, seem to be getting ignored by the perl mime parser, since it headers doesn't seem to have the filename, due to which application is not able to recognize the file as attachment.

Any insight on how this issue can be resolved.

Thank you,

    Can you post an example of input data and your code so we can reproduce the problem?

    I have Perl code parsing attachments using MIME::Parser without problems, but that may be because I've never encountered attachments that you seem to have.

      Hi Corion, sorry for late reply.

      But, below is what input for rfc-822 attachment input looks like,

      Thank you.

        There are weird newlines / empty lines your example post. Are these also in your input data? If so, that is likely a cause for the attachment not conforming to the MIME specification.
