It looks like it would be a matter of adding an extra field to `struct robot`,
adding a new key to set it, then having `import_netmail()` return some
appropriate non-zero magic value when the robot name is matched instead of
continuing at `sbbsecho.c:4700` and updating echocfg.c to allow setting it.
