mail spam test

Hi
Anyone tested the spam filter ?
I tested mine with a low spam code that i found googlin
copy the text below and send it by email

This is the GTUBE, the
Generic
Test for
Unsolicited
Bulk
Email

If your spam filter supports it, the GTUBE provides a test by which you
can verify that the filter is installed correctly and is detecting incoming
spam. You can send yourself a test mail containing the following string of
characters (in upper case and with no white spaces and line breaks):

XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X

You should send this test mail from an account outside of your network
