 * Hi [@bikebear](https://wordpress.org/support/users/bikebear/),
 * Thanks for reaching out! Could you please check whether you can send a test email
   by head over to the **WP Mail SMTP -> Settings -> Email Test** area?
 * If your test emails are working, you need to check the following.
 * **1)** Check whether you have any forms on your site or plugins that are sending
   emails with attachments. Most probably you may have exceeded the attachment size
   accepted by your email account.
 * **2)** Check your email notifications and see whether your “reply-to” email is
   different than your “from email” address. Some email platforms like Yahoo are
   not accepting different “reply-to” email addresses when delivering emails.
 * Could you please give it a try and let us know how it goes.
 * Thanks!

 * Hi [@bikebear](https://wordpress.org/support/users/bikebear/),
 * Are you able to send test emails under the **WP Mail SMTP -> Settings -> Email
   Test** area?
 * Could you also please force your “from email” under the **WP Mail SMTP -> Settings**
   and see if that helps.
 * Thanks!
