Well, do THEY have it turned on? From: [email protected] [mailto:[email protected]] On Behalf Of Adrian D. Henderson Sent: Tuesday, August 11, 2015 1:16 PM To: [email protected] Subject: [Exchange] Stumped. False positive content restriction Ex2010
Got a customer on Ex2010 with forefront 2010 protection on it. Content restriction checking is disabled in EMC. They have a customer who can’t email them, or so the story goes. Customer sends a test email to me and them, now neither of us can reply to it, '550 5.7.1 Message rejected due to content restrictions' I had received and replied to emails from her earlier in the day no problem. So I was thinking it was her signature. I made a new email to both people, goes through. She replies to that one, I reply further asking if she got a reply from the other party and it bounces back!? I have added my domain and email addresses to the filter list in FPE, saved, but still being blocked. I haven’t bothered with IP whitelisting as the other end is on O365. That’s probably going to have a big long list I bet. Any ideas? Scratching my head here…..
