Email issues with yahoo mail accounts
I have created a simple contact form with CSS Form Builder that sends an email out on submission.
The emails are not received by yahoo ,att.net(powered by yahoo) or lycos email accounts . All other email addresses that I test appear to work fine and receive the email instantly.
There was another post about this that said to hardcode the from address and make a change to the mail.php page. I tried both of these with no success.
Is there something else I can try so that the emails can be delivered to accounts on these mail servers?
Thanks for your help
