This should be done from the virus filter. A antivirus smtp proxy should
have such an option, to relay email traffic (for some domains/networks)
to a specific mail server.

It is a good solution, but it depends on the email traffic volume and
the resources constrains (hardware, server load)

Yes, any additional filter cause extra overhead. But it depends on the
email traffic and the hardware resources. But it is still the best
solution since it can filter inbound and outbound traffic without
additional settings or programs.
