On a clients domain only one email address is getting rejected from sending to a handfull of domains with smtp;550 Rule imposed as JimQ@xxxxxx.com is blacklisted on Spamhaus see spamhaus. I have checked the domain on spamhaus as well as ip address and nothing shows as being blacklisted. I also have never heard of just one email address being blacklisted only ip address or domain name. The issue started with an exchange 2003 server. We have replaced the 2003 exchange server with a SBS 2011 server running Exchange 2010.
