Support » Fixing WordPress » New user notification / verification mail not sending

  • After registering on our website users are verified/approved and should be receiving a verification mail. The user is added through wp_insert_user(), added to the blog through add_user_to_blog and should be receiving a notification by wp_new_user_notification. However, no mail is received. Resending the validation email from the dashboard sends an empty mail with no subject. There seems to be an error raised by WP mail SMTP as well, but it is not very helpful:

    Mailer: Other SMTP
    SMTP Error: data not accepted.

    Test mails however seem to work, as well as password reset mails. Forced from email is set and the same username and from mail is used.

    This has previously worked and no changes have been made so I suspect some update messed things up, but this is just a guess. What could be the issue?
