From: Tegger on
A supplier is sending me messages from his very new Macintosh with Apple
Mail. These messages have attachments.

When I (as a PC user) receive the messages, attachments are missing
entirely in Thunderbird and are present but not decodable in Outlook
Express.

The supplier has the "Send Windows-friendly attachments" box checked.

I have traced the problem down to one line in the base-64 header which
immediately precedes the attachment data. Specifically, it's the
"Content-Id:" line.

If I open up the message source, remove this line and resave the message,
the attachment is then available normally in both Thunderbird and Outlook
Express.

My question: is there some way of telling Apple Mail not to put the
"Content-Id:" line in the header?

Thanks. I'll pass that along.

But when I study my supplier's message source, it appears he's already done
this.

I don't think this problem has anything to do with where the attachment is
placed, it has solely to do with that pesky "Content-Id:" line in the
base-64 header. Unless Apple puts that line in there only when the
attachment is not at the absolute bottom of the message, which would be
kind of retarded.

How come Apple is the only one that uses a "Content-Id:" line? What
possible purpose could it serve other than to mess everybody else up? Who
does Steve Jobs think he is? Bill Gates?

Nah, it's only interesting that Thunderbird chokes. Lookout choking is no
surprise at all. ;)

I found this, though it's about SENDING attachments. Still, it might help:

I did forget that Thunderbird has some 'issues' with attachments.

Hmm.. I just fired up Thunderbiord 2.0.0.9 and pointed it at my IMAP account
and went to a mail I'd sent from Mail.app with several photo attachments.
Thunderbird displayed it fine.

OK, tell your Mac user to sent in PLAIN TEXT instead of Rich Text (My mail
send Plain Text only). Your attachments will show up fine.
