[Plugin: Fast Secure Contact Form] Problem with text file attachments

Greetings:

I’m using the latest version of “Fast Secure Contact Form” with the latest version of WordPress at https://www.factionalwarfare.info/contact-mara-abraham/

The main purpose of the form is for fellow players to attach their combat log files; these files are plain ASCII next with the extension of .txt

When a person uses the contact form to send an email attaching a .txt file, the text file is included in the body of the email rather than being treated as a separate attachment.

This is causing a severe problem because the formatting is not preserved; in the body of the email, the text file word wraps.

This causes a problem for the combat log analyzer I’m using.

Is there a way to have the Fast Secure Contact Form send the attachment as an attachment (not within the email body) without forcing the sender to compress (zip) the attachment?

If so, how?

If not, can you recommend another WordPress Plugin that allows the easy set up of a contact form that sends text file attachments as pure attachments (not embedded in the body of the email?

Thank you.
