You have Exim configured to do DNS lookups on connecting hosts. The one in
question doesn't have a complete DNS setup - in this case the reverse
lookup succeeded but the forward lookup of the hostname obtained during
the reverse lookup doesn't exist.
No, you don't have to do anything - the message is for information only.
You could tighten up your acls to refuse or otherwise treat differently
mail from that class of host. But only if you want to.
