Is there anything I can do to mitigate this?
Do you publish SPF records?
Logically this should have an effect, but in real-world terms, it
doesn't. So don't worry about it.
Sure it won't if nobody ever publishes any SPF records.
Instead, try enabling the vbounce ruleset...
Certainly, do that. But *also* publish SPF records so that the people who
*do* check SPF have a chance to reject forgeries proactively.
