Hello, I am starting to get mail return-to-sender failures sent back
to a server for one addressee.
The script wants to send the message to Bozo@??? (Names
left of the '@' changed. I have left the domain name unsanitized)
The failure msg looks like this:

=====================================
That line "for name=data.h-ems.com.h-ems.com type=A: Host not found"
looks to me almost like a blatant typo/clerical error in somebody's
setup.
Looks to me like Bozo@??? is
translated/resolved/forwarded (never quite sure of the terminology) to
Bozo2@???,
but then whilst it is trying to resolve Bozo2@???,
gateway1.messagingengine.com. finds that data.h-ems.com.h-ems.com does
not exist.
I am not sure how/why Bozo3@??? comes in to it. I'd have
though the whole thing would have failed before it got as far as him.
Can somebody indicate from this information, what sequence of
processes going on? I'd actually find it quite useful to get more of
an idea of what is happening.
Thanks!
