I have tried a number of different forms programs and they sometimes work, sometimes don't. They work on one domain for a little while, then they stop working again. I have the most recent versions of everything. It's not an email problem as far as I can tell, all my email accounts seem to test out fine. I am able to use other plugins that require email, like the backup program that emails me weekly backups. It's just nothing with a form. Any ideas? I have tried Sweet Captcha, Contact Form 7, Fast Secure Contact Form, Easy Contact Forms. They all appear to go through the motions, I get a "success" notification, but no email comes through.
