 * Hi,
    We are facing an issue when sending emails that says SMTP Error: data not
   accepted. We looked at others posts having the same problem, and we did everything
   said in them. However it did not solve our problem, and the more weird about 
   it is that sometimes the emails are sent and sometimes not, without doing anything.
   Could you please hlep us out? Thanks a lot, Regards.

 * Hi [@gmuela](https://wordpress.org/support/users/gmuela/),
   Thanks for reaching
   out! In most cases, you may experience the error “data not accepted” because 
   of the following reasons.
 * **1)** You have authenticated the WP Mail SMTP plugin using one email address(
   info@example.com) but you’re trying to send an email using a different email 
   address (support@example.com).
 * **2)** Your email provider is not allowing you to use a different “reply-to” 
   email. In that case, you need to use the same WP Mail SMTP authenticated email
   as your “reply-to” email.
 * **3)** You’re trying to send an email notification with an attachment, but you
   have exceeded the attachment size limitation.
 * I hope this helps to troubleshoot the issue.
   Thanks! 🙂
