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
mailto:me at
etc... no dice...

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

Thanks in advance for any hints!
