Mail attachments

[MCAsan]

It seems as if many Windows email clients can not separate and see a jpg attachment to a email from a Mac. From what I can find there are 3 things that can be done on the Mac side.
1. Do plain text instead of HTML
2. Do Windows friendly attachments
3. Put attachments at end of message

Anything more?

I heard from the receiver. It was only after I used plain text that his client could pick out the attachment. I assume he was using Outlook...don't know for sure.
