This is my experience as well. It suddenly stopped sending autoresponse emails to the person who used the contact form on the site. The [email* your-email] syntax that the site says to use doesnt work anymore. So I cannot get it to respond to those who use it. I received the same response from the plugin author and never anything after.

https://drmcontrols.com/careers/ has the issue of not sending any email whatsoever and won’t send out a receipt email due to the mail (2) error.
https://drmcontrols.com/contact/ has the issue of receiving but only one person is getting the email to their junk rather than 4 individuals like it was before.
