Did you try that website? They have lists of non SSL smtp servers! Just chose one input it in and see if it works!
For those of you confused, a script file is like a batch file. You create a file that will automatically open the email program, send a preformed txt file and then close the program.
(I have alot of computer back ground)
The AC3 has an option to run an external program. So just do the above.
Heres another website to explain it alot better.
