[AFMUG] Email blocked because of Client IP, not Server IP

[Nate Burke]

I have a customer complaining about barracuda rejecting emails he is 
sending because of a 'reputation' problem.  But the IP Address they 
reference is the end user's IP, not the server IP.  Shouldn't the 
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.
