Mechiel Lukkien d1e93020d8 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!		2023-10-25 13:01:11 +02:00
