2 word spam subject starting with "at"/"for"/"good"

[Tuc at T-B-O-H.NET]

Hi,

        Is anyone else seeing these. They seem to have 2 word subjects
starting with "at", "for" or "good". I don't seem to get any personally,
but one of my users seems to get 500 or 600 a week....

                        Thanks, Tuc
