I think that should already work, according to
<file:///usr/share/doc/exim4-base/README.Debian.html>:
2.1.1.7. IP address or host name of the outgoing smarthost

Please enter the IP address or the host name of a mail server that this system
should use as outgoing smarthost. If the smarthost only accepts your mail on a
port different from TCP/25, append two colons and the port number (for example
smarthost.example::587 or 192.168.254.254::2525). Colons in IPv6 addresses need
to be doubled.

If the smarthost requires authentication, please refer to Section 2.3,
“SMTP-AUTH” for notes about setting up SMTP authentication.

Multiple smarthost entries are permitted, semicolon separated. Each of the
hosts is tried, in the order specified (See Exim specification, chapter 20.5).
