Multipart email

Hi all

I need FileMaker to send out 'multipart/alternative' emails with the following contents:

• Part 1: text/html (or whatever you like) - this is displayed to "ordinary" mail readers or as a fall-back and contains a summary of the event in human readable form
• Part 2: text/calendar; method=REQUEST, holds the contents of the ics file (the header method parameter must match the method in the ics). Watch out for the correct text encoding, declaring a charset header parameter won't hurt.

I'm trying to recreate Outlook calendar invite emails. Apparently it is possible, but I don't know whether FM/SM can achieve this: http://stackoverflow.com/questions/461889/sending-outlook-meeting-requests-without-outlook

Any help appreciated.

Many thanks
