That means you are not going through a different network to get to the server, and the lower security options offered by port 25 will work just fine. If the SMTP port was set to 25, this may work from home, especially when the email server is from your Internet provider. But there are some factors that can cause it to fail when you are connecting through a different network. You don’t have to change your server just because you are travelling. But when you normally have a local ISP internet mail server connection like with TPG and are out of the country, you can get problems sending unless you have the right country SMTP setting.

If you use a global non isp mail service like eg: Gmail, Hotmail, iCloud etc in eM Client, then the same SMTP mail settings work normally anywhere in the world even on free internet service. So send mail via that and BCC yourself when you send, so you have a copy of the sent mail and can drag that to your eM Client sent box folder. However if you are using a “non ISP internet connection” out of Australia to just use “on a temporary basis”, then you should use your “TPG webmail” to send mail till you are back in Australia to avoid SMTP server sending issues. So if you are using a local ISP internet connection in France, dblcheck with their tech support staff on what SMTP setting to use.

If you are out of Australia you normally need to use the SMTP server settings of the physical internet ISP connection of who you are currently connecting to there in that country as or you can get “relaying SMTP errors”.
