I don't have any examples off-hand, but here are a couple "gothcas" that the MIME coders may want to be aware of.

  1. Some mail software attaches a "file" with message attributes. I would consider these MIME attachments as "garbage" and not bother saving them into a file. Two mail clients that I know of that do this are:
         Content-Type: application/octet-stream; name="ATTRIBS.BND"
       MS Exchange (Outlook???)
         Content-Type: application/ms-tnef; name="WINMAIL.DAT"
         Content-Type: application/; name="WINMAIL.DAT"

  2. Mail clients that send TWO copies of the same as
     text/plain and one as text/html.  If you trust the HTML encoding,
     this can be a Good Thing as most of your work is done for you.  If
     not, discard the HTML and process the text.  The only two I know of
     off-hand are:

       Netscape Mail
       CyberDog (a Mac OS web/mail client that used OpenDoc technology)

     The tricky part is knowing when this feature has been activated or
     deactived for a given message.

  3. And finally, if you're going to use the attachment's real filename,
     note that some attachments may not have filenames, so make sure to
     have a backup naming scheme just in case.

I've created patches to Hypermail in the past (I believe they were passed on to Kent through the former maintainer, Kevin), but haven't had a chance to look at the latest release. I will most likely be reworking the HTML archives at work in the next couple of months and hope to take a look at Hypermail again at that time.

For now, I'll continue to lurk on hypermail-digest. :^)
