How can you solve it? Talk to the person who maintains your SMTP server.
What does it mean? The SMTP server that handles mail for mmp.in is looking
at the ip address of the machine talking to it and checking to see if that
ip address has a fully qualified domain name attached to it, which it
doesn't appear to, so is assuming it is spam.
