After years of working correctly, the gd form mailer function stopped sending an e-mail in November 2018. I did not change any coding. Then all of a sudden a folder appeared on my web directory called "BadGDFormMail" which contained files of the inputted values from the forms submitted. What happened? Is GoDaddy no longer supporting gd formmailer? How do I fix it?
I would like to know the same answer! I just discovered that I haven't been receiving emails since November of 2018, and the same as you: they are all in a folder that I didn't know existed!
