Possible off-topic alert, I'm asking this here because msbl-db01.hotmail.com seems to limit itself to targeting our Listserv engine, and I'm wondering if other Listmasters see it or know what it is. Basically, msbl-db01.hotmail.com shows up in the logs every afternoon, at no fixed time, attempting to *telnet* into our Listserv engine about 18 times. In writing this I just noticed that it's also generating some 404's on the web interface at the same time. It has been doing this for many months at least, more likely a couple of years, and inquiries about it directed to various hotmail addresses simply vanish. I don't recall ever getting anything out of it from a port scan, and running "msbl-db01" past Google merely shows it as being on other peoples radar for the last two years. -Kary
