This message is a test probe, to ensure that your mail server is secured
against third-party mail relay. This is NOT an attempt to hack or crack
your system, but just to ensure the system(s) are secured against this
common
vulnerability.
A well-configured mail server should NOT relay third-party email.
Otherwise, the server is subject to attack and hijack by Internet vandals
and spammers.

The IP 211.252.155.94 is South Korea - I'm in UK - So would I be right in
assuming this is in fact some sort of spammer probe to see if I was an open
relay? Which I'm not!
Looks like its permanently bye bye 211.232 - 211.255 for email access to my
box later on!
