In such a case, when you KNOW there's something wrong with the receiving
side, wouldn't it be better for your host to hold all mails to that
server alltogether?
Like with the 'hold_domains = domainlist' configuration setting?
Or some lookup in your routers that fails if the domain is in some
fail-list?
There's tons of other options besides mangling the source to deviate
from RFC-standards.
