I am going crazy about this error message.

for some of the domains, I am receiving this error message;

Reason: Remote SMTP Server Returned: 550 5.7.1 Unable to relay for info@example.com

I am using MailEnable on windows server 2008 r2. I have just migrated the whole domain from windows server 2003 and the e-mails worked just fine there.

What would solve this problem?

"I have just migrated the whole domain from windows server 2003 and the e-mails worked just fine there."

Have you changed domain naming (from address) during your migration?

not that I know of. but I am still keeping the other server alive just in case. I changed the dns though. –  tugberk Jul 15 '11 at 10:02
    
You might check your "return" addresses and maybe with the Black/Block Lists to ensure your server is not somehow being listed. –  user48838 Jul 15 '11 at 10:20
    
where can I check that? –  tugberk Jul 15 '11 at 14:18
    
The following is a pretty good one that covers a lot of the prevailing lists - mxtoolbox.com/blacklists.aspx. –  user48838 Jul 15 '11 at 17:45
