website form not sending email (godaddy hosting)

website form not sending email (godaddy hosting)

I recently opened a zoho account and changed my website form & mail.php to point to the zoho address.
Prior to this the website form was working fine with a test gmail acct.

domain is verified & mx records are correct but no mail from site form. Email sent from a client is received through zoho just not from site.

Can someone help?

Also, does zoho require any txt records be added in the dns zone file?

much thanks,
john
