Requirements for using SMTP server to send email

Interspire Email Marketer needs the following in order to be able to send email using SMTP:
  • "fsocketopen" function needs to be enabled -- this is enabled by default in PHP installation
  • Outgoing traffic to port 25 (or whichever port number you use to connect to your SMTP server -- 25 is the default port number) must be allowed
  • Valid SMTP server for you to use
If one or more of the list above is not satisfied, you can receive errors such as
  • "No Connection"
  • "Unauthorized"
  • "Timed Out"
