I have updated to the latest version of Enfold and am still not receiving some small percentage of messages. It appears that the problem may be limited to contact forms that use a Yahoo.com email address (but possibly also a few aol and gmail addresses). I have not received a single form that used a Yahoo address.
I have tried Contact Form 7 and Yahoo addresses are coming through. I would prefer not to rebuild all my forms in Contact Form 7, however.
Do you have any other ideas?
