Yes. You probably need a mix of strict SPF records in your domain,
employ SPF checking in your MTA and accept authenticated only SMTP

This has the positive side effect of other mail systems being able to
use these SPF records to check if they people are pretending to be

When using SPF, it's also a good idea to use DKIM too.
