I remember having issues with this when developing the code and not
being able to decode them. I *think* it was when forwarding emails
though, and involved the entire message body. I hid the attachment
since there was nothing we could do with it on the client side in the
clients I tested.

I will take a look at this again, as it relates to attachments and
"unhide" the attachment.

Another point to pass on the original winmail.dat attachment:
Outlook 2013 accessing it via ActiveSync will probably be able to handle it.

That needs testing though (which I would volunteer to do once we have
a "fix").

I would consider this an enhancement, not a bug.

Indeed. Good point :)

Here's a tested and working patch.

Outlook 2013 handles winmail.dat attachments without the blink of an eye.

Yeah, that's the easy way out ;)

I'd like to parse out the attachment data from the TNEF file when
possible and add them as "normal" attachments. Of course, I'll only do
this for non-cryptographically signed messages. I'll have to
investigate if we should strip the *.dat file when we are able to
extract the attachments since this would needlessly increase bandwidth
usage.

I remembered what the problem was originally for me - it was when
dealing with meeting request responses - which are also sometimes
bundled in the TNEF data. Our library didn't include support for
extracting the data and quite honestly it looked like more work than
it was worth to implement it on my own time :)

Not sure if it's only the easy way out ;)

We could let Outlook 2013 also handle the meeting response in the
winmail.dat file.
Parsing on the horde side might potentially break some Outlook
specific extra information in there.

Agreed. That's why I'd still include the *.dat file if we couldn't
parse it, or if it's a meeting response etc...

I'd prefer to not have to resort to third party applications to view
an attachment on the client that the user is used to being able to see
as-is using IMP.

Initial support done. Now parses out the same data IMP is able to.
Will send the raw .dat attachment if it contains no parse-able data.
