I have changed the default sender e-mail address (wordpress@fqdn) in my Wordpress website and it works also for WP Cerber e-mails with subject beginning with “WP Cerber: A new version of” but for the ones sent with the subject “WP Cerber: Number of lockouts is increasing”.
I cannot see in WP Cerber settings where to change this.
Can you, please, correct this behaviour?
I can do some tests for you if needed.
WP Cerber sends all its emails using the standard WordPress function wp_mail(), and it does not use a separate email transport for specific notifications. At least in the free version.
Since you are seeing different sender addresses for different WP Cerber emails, this suggests that the sender address is being modified outside of WP Cerber, most likely by an SMTP plugin or a WordPress filter that applies conditionally.
Please let me know what plugin or method you use to change the sender email address.
If you need full control over email sending, including SMTP configuration and consistent sender settings for all notifications, this is available in the professional version of WP Cerber.
