Did the 'net fubar some email systems?

I have been running exchange 2010 for at least a year and using ORF as our antispam. For some reason, today, many of our clients have been getting bounceback emails sending to us. Its been a PITA filtering out the domains so I turned off the antispam on our AV system (ESET). Anyone else getting this today? Many of the people whos email is getting rejected by us are utilizing bigfish-dot-com. I wonder if MS screwed something up over the weekend.

Without you telling us why the messages are being bounced back, there's nothing we can suggest.

The NDR will say exactly why the message is being rejected.

I know microsoft recently released their 2012 exchange patch to make it backwards compatable . . . maybe some people are finally attempting that migration and not doing it right?

Post the NDR's.

Check the senders MX records to see if they've been blacklisted.

2013 - and I doubt that has anything to do with it.

ESET update was heavy on the spam. I adjusted it.
