Sending email with TLS (via Outlook) from LC 6.7 based app...

[matthias_livecode_150811 at m-r-d.de]

You could send out the emails with the command line tool curl using LC's shell function.

https://everything.curl.dev/usingcurl/smtp

So instead of calling the libSMTP library you create the email according to RFC to have correct smtp headers and sent it using curl through the shell() function.
That's the way how i did it at the time when tsNET was not yet released and i needed to send emails using TLS.

As 6.7.1 does not contain any of the mime library, you need to create the the raw email manually.

This lesson here
https://lessons.livecode.com/m/4070/l/8184-sending-emails-from-livecode-server-scripts

explains how to send emails from Livecode Server scripts. The 
Please have a look at the sections about 'Formatting Email Headers' and 'Adding Attachments'. That information should give you a clue how to create the data correctly.

There is a huge amount of text to be processed, and - as you might imagine after this long development, with regular changes and additions - the processing is very complex. A few years ago I did look at rebuilding it in LC 8/9, but because of the changes to unicode handling there was a lot of perturbation in the data, and there wasn't time/budget to track all this down in order to get a reasonable new version. I still occasionally need to make tweaks to the processing, but I do that in my trusty LC 6.7.11.

Or (I'm not a Windows person) is there some simple way I could set up a local SMTP server on the Windows box that would accept the email from my LiveCode app and forward it to outlook365?
