give delivering to mx targets with underscores in name a chance of succeeding ...

the underscores aren't valid, but have been seen in the wild, so we have a
workaround for them. there are limitations, it won't work with idna domains.
and if the domain has other policies, like mta-sts, the mx host won't pass
either.

after report from richard g about delivery issue, thanks!
