Plugin / Post SMTP Mailer/Email Log

Installation

To send email reliably, you must use the SMTP server assigned to that email. If Post is unable to connect to the right SMTP server, you may have to ask your host to open the ports, or create a new email account managed by your host, or switch hosts!

The Connectivity Test utility will tell you which ports are open and the actions available to you.
