Hi all, 

Sorry for the noise, but one of my clients is getting the standard "it's the
other guy's fault" with some email delivery issues to/from Proofpoint
"Enterprise" customers.  If there is anyone from Proofpoint support
monitoring this list, some assistance troubleshooting email delivery issues
would be greatly appreciated.

Thank you,

Tim Donahue
