FYI, I made both changes and am still getting about 20 in 12 hours. I am just direct them to the deleted folder.

Just for our info. After testing and use for awhile, is there more info/value from these emails than just that the database is down?

All of the failures are because of the recaptcha. I noticed that the phone number is always 123456, the email appears to be correctly formed. In the drop down box, they always choose the same 2 options, the comment area, will usually have garbage, sometimes just "Sexua/pornol" words sometimes URLs. The IP address is always different.
