Do you know which OS and email software these people are using? I'm not sure that I exactly understand the complaint here. When I use the script to send myself an email message to my Outlook account, yes the attachments are below the body. If Outlook didn't put it somewhere, I'm sure how I would deal with it...
Are you saying that that mailer is opening the attachment and displaying it?
Well whatever the problem is here, I do have something that you can try. When I wrote that script I send myself emails from various mail programs to see what they did. I saw two techniques in use. I went with the simpler one because I saw that it worked. To try the more complex technique, after the line that says:
Code:
print - 'Content-Type: TEXT/PLAIN; charset=US-ASCII; name='${ATTACHMENT}
add this line...
print - 'Content-Disposition: attachment; filename='${ATTACHMENT}
Let me know if this works better for you. I'm in the midst of writing a successor to mimetool and I'll add that line to it if it helps with some software.
