This came from IP address 126.96.36.199, a Korean address. 188.8.131.52/23 has been given to KORNET-HOTLINE2003220208-KR. Blars has it listed (127.1.0.32) as a subnet that hosts spammer sites.
The address of the autoabstract.rxmedsifsite.com website is 184.108.40.206, which according to whois is a Chinese netblock.
The name TraciLFU4775, I leave to the reader's imagination. If the name is meant to belong to someone called Tracy then we are expected to believe that this person may (or may not) have been sending messages with AIM (AOL Instant Messenger). I don't know anything about AIM, but judging by their home page ( http://www.aim.com/get_aim/express/aim_expr.adp?aolp= ) I probably will not experience it unless I start browsing with MSIE or Netscape 7.1. (the only browsers that they say they support).
And it seems that if instant messenger (of the AOL or Microsoft variety) had been invented first, email would have seemed a marvelous invention!
