The SMTP provides a set of codes that will simplify the communication of email messages and email servers. However, if you are unable to send email using SMTP, there is a way of fixing this problem. Which, you’ll learn in this guide.
Presuming it has been correctly configured then it is likely due the ISP blocking access to the server.
Unfortunately, in this instance the only solution is to use the ISP's outgoing mail server. Here is a partial list of outgoing servers for some popular ISPs:
|People Telecom WA
|People Telecom NSW
|People Telecom VIC
|People Telecom QLD
|People Telecom SA & NT
|esmtp.unwired.com.au (Yes, the e should be there.)
My Isp Is Not on This List
You will need to contact your Internet Service provider and ask for the outgoing mail server settings. It will more then likely look like mail.myisp.com or smtp.myisp.com.
