mailto: string with attachment

[Klaus major-k]

Hi all,

did someone successfully create a "mailto:" string 
with attachment on a Mac? And did it work when using:
...
launch url (the_mailto_string)
...

If yes, what is the exact syntax?

I tried gazillion variations of the basic string:
mailto:me at example.com?subject=Test&body=Body%20text&attachment-url=file:///full/path/to/file.xyz
mailto:me at example.com?subject=Test&body=Body%20text&attachment=full/path/to/file.xyz
etc... no dice...

But maybe attachments in a "mailto:" url are prohibited on the Mac for security reasons?

Thanks in advance for any hints!


Best

Klaus
