<p class="MsoNormal">Hello all! New linux guy here and Zend.To is my second linux project to get going here at the city. I set up Zabbix monitoring a couple months ago and have those emails going out to our external email addresses so I know I’m doing some
things right.<br>
And Zend.To I have internal emails going to internal users when I set it up to send with no authentication, and I have of course tried the exact same port, encryption TLS, and exchange account and password, and every other combo.
