Well, it's obvious that your transaction is bogus. You have an empty
MAIL FROM: and RCPT TO:.

Furthermore, is "domain.com" YOUR domain? It IS valid, but belongs to
one of those domain name scalpers. Are you trying to be cute and use an
example? Does the REAL domain that you are testing truely exist and have
an MX record? Are the DNS servers for it up and working?

Obfuscating info is understandable, but if you do it too much or snip
too much, nobody is going to be able to help you.
