Can you connect with telnet?
$ telnet smtp.iprimus.com.au 25

No.

The "domain" setting is used as a parameter for the EHLO command, which
is the first command sent to the SMTP server.

Since msmtp cannot connect to the server, it cannot send the initial
"EHLO localhost".

Historically, the EHLO parameter should match the IP address of the host
you're connecting from, but nowadays it does not serve a purpose
anymore.  The SMTP server is not allowed to reject delivery because of
an EHLO argument that does not match the senders IP address (RFC 1123,
section 5.2.5). The default "localhost" seems to almost always work.
