For attachments, the array can be one of two methods:

(1) $arr["full_filename"] => "filename" or (2) $arr['filename'] = "string that makes up atachment"

For method #2, $bool_string_attachment must be set to TRUE.

This is the main module file for SMTP, which will let us send emails using SMTP instead of PHP's mail() command.

Code
