Sometimes scammers will try to lure you with a "dating scam" - usually a trick to gain money or possibly a visa. The basic setup is described here at Hoax-Slayer.com.
Often, these scams will use a throwaway email address at Hotmail, Yahoo or Gmail for responses, however these are often shut down so the latest trick is to register domains that look like genuine webmail addresses but aren't. Here's an example:
Hello! I am bored this afternoon. I am nice girl that would like to chat with you. Email me at firstname.lastname@example.org only, because I am writing not from my personal email. Don't miss some of my naughty pictures.(Note the phrase "I am writing not from my personal email", because this comes from a spoofed address to make it harder to block.)
Now, mailmessagecenter.info looks like the sort of domain name you'd associate with a webmail account. In fact, it's hosted on a Chinese server at 22.214.171.124 along with a number of other domains. It appears that all of these domain names have been created to pursue this scam, so if you receive and email from any of them then just delete it.
