SBS2011 Email High number of sent emails are marked as spam and blocked by recipiants
Hi we have just moved to SBS2011 and have noticed a higher number of emails we send being blocked as spam by recipient networks.
I have done some fualt finding and have uncovered what i think may be setup errors that I need to repair.
First the Smart Host wizard in the sbs console wont run- it comes up and says the configure Internet email cannot continue. The Internet send connector for exchange server is missing - To resolve this run the fix my network.
I do this and get an Internet port mapping is missing and Exchange SMTP connector is invalid
I run the fix and wizard fails with just red x's
I get a list of ports which are open to the server and Exchange is not running which it is. I have had to create the send connector manually for our ISP smart host
But we are getting a number of domains that now reject our email as spam. Normally we get a NDR with 554 Denied on it.
How can I fix these faults and are they related - I suspect so
Many Thanks for help

May be problem is in IP v6 in your Exchange server. I think many spam filters and mail servers have problems if IP address of originating server is IP v6.
I have not made something specific, but my Exchange 2010 server have IP v4 address in message header.
May be you had to add "Remove x-originating-ip header":

Hi I have removed the x-originating-ip-header but that seems to have made no differnce. The reseacrh I have done suggests that removeing ipv6 from the server is a non supported move and can cause problems in the network. But does show up there meay be an issue with ip6 addressing on some mail servers
So we have no fix at the moment but do seem to be on a track as this appears to be connected to the move to Exchange 2010 we had none of these issues in exchange 2003
