If you have very old software such as Windows 7 or Windows 8 you may be having problems sending and/or receiving emails via our mail servers.
When your email software attempts to connect to our mail server it uses encryption to make it secure against eavesdroppers/hackers.
There are several versions of encryption used by email servers. These are TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3.
Internet standards have disallowed the use of TLS 1.0 and TLS 1.1 since 2019 as they are obsolete and have security vulnerabilities as explained here -

However Windows 7 and some early versions of Windows 8 don't automatically support TLS 1.2 or TLS 1.3.
In line with internet standards, our mail servers no longer accept TLS 1.0 or TLS 1.1 or any unencrypted connection attempts.
Therefore, if your email software is trying to connect to our mail servers using TLS 1.0 or TLS 1.1 they will fail to connect. It will often show an error message similar to "Your server does not support the connection encryption type you have specified."
The recommended solution is to upgrade your software to the latest versions to ensure they're using the latest connection methods with the greatest levels of security.
However if you want to try to get your old software connecting successfully to our servers here is some information that may help -

That is best done by an IT expert, and unfortunately we can't provide any support regarding this.
Alternatively, you can send/receive emails via webmail by visiting https://webmail.yourdomain.com.au (replace "yourdomain.com.au" with whatever your domain is).
