Fix PHPMailer Email Form Error
Budget: $10 – $30 USD
All contact and booking forms on my two custom HTML sites have stopped delivering mail. Every submission now throws the following PHPMailer message:
“Message could not be sent. Mailer Error: SMTP Error: Could not connect to SMTP host… stream_socket_enable_crypto(): SSL operation failed… tlsv1 alert protocol version… QUIT command failed”.
Nothing else on the sites has changed, so I suspect an outdated PHPMailer version or deprecated TLS setting is blocking the handshake with our SMTP host.
