Yeah, it's an option the Barracuda administrator shouldn't turn on, but good
luck convincing them it's their mistake.
Many of the big email providers are starting to hide the "Received: " lines
before their mailserver so the client IP header isn't there. I have also
seen tutorials on making Postfix strip the Received: header before relaying.

I have a customer complaining about barracuda rejecting emails he is

reputation be based on the Mail server, not where the mailserver had
sourced the email from?
Is this a setting in Barracuda? I don't see any other rejections from
barracuda appliances except to this one domain.
Yeah it's called "deep scanning" or "deep header checking" something
like that. It makes it check all IP addresses in all the headers, not
just the connecting server's IP.
