- My contact forms ONLY work if I use my gmail address as the address of the person filling out the form.  For all other addresses, the form doesn't go through.  (That is the email I originally used to sign up with Zoho.  Not sure what that means)

-  To try and fix this, I've installed the WordPress plugin 'Configure SMTP.'  I've attached a screen shot of the settings I'm using.  

- This did not fix it.  When a user fills out the form, they get an error.  When I try to send a test email using 'Configure SMTP,' I get a 'relaying disallowed' error.

Note:  My email accounts work fine for sending and receiving email.  It's just the contact forms.

Has anyone experienced anything like this?  If so, I'd love to hear what you did to fix it!  Desperate to get my forms working.

Thanks!
