Hi, run a test from System/Delivery panel and if it report “success” but no email is actually delivered, you need to open a ticket to the hosting provider or SMTP provider.

Hi @satollo,
Good day! Thank you for your information.
Actually after checking, the mail module still using wp_mail() to send mail, and I’m also manage the mail services and I’m ensure there is no MTA logs showing in our mail system. (But when telnet from wordpress server to relay is working fine), is there any further suggestion on it?
(btw, I found one article said need to install stmp module, is it correct?)
Hi, the Newsletter plugin uses wp_mail() by default, but if the blog has an SMTP plugin, the wp_mail() function could be modified by that plugin. Try to check if you’re running an SMTP plugin and do some tests from that plugin. If wp_mail() is not modified by a plugin, the function is using the mail() function of php which relies on sendmail installed on the server (or the php-smtp configuration under windows). That is the failing point, so you need a system administrator to check why the server is not able to send. Under linux the var/log/mailog is a good starting point.
