Re: rfc822 type attachment (.msg ) file is not getting recognized.

[Corion]

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.

[Corion]

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.

[Anonymous Monk]

Hi Corion, update:

Upon using $parser->extract_nested_messages(0); option, code seems extracting the rfc822 attachment (.msg) file but that's not in binary format, it seems to be in base64 encoded .msg file.

This file doesn't get open by the outlook for some reason.

Any input on this would be appreciated!

Thank you.

[Anonymous Monk]

Hi Corion, Thank you for the revert and pointing out the root cause.

Yes, this is how input which is getting written in the file looks like.

With the same format all other attached files seems to be getting recognized except this rfc-822 type.

Apart from weird newlines/empty lines, could absence of filename in the attachment and description headers, cause this?

Thank you.
