Hi @medicmandan,
Thanks for reaching out! Generally, you may experience the “data not accepted” error because of the following reasons.
1) You have authenticated the Easy WP SMTP plugin using one email address ([email protected]), but you’re trying to send an email using a different email address ([email protected]). You can enable the “force from email” option under the Easy WP SMTP settings page to resolve this issue.
2) Your email provider is not allowing you to use a different “reply-to” email. In that case, you need to use the same Easy WP SMTP authenticated email as your “reply-to” email. You need to check your form notification settings to resolve this issue.
3) You’re trying to send an email notification with an attachment, but you have exceeded the attachment size limit of your email provider. You need to get in touch with your email provider to find out their attachment limitations.
I hope this helps to troubleshoot the issue. Thanks!
