You are not the only one. Seems to be increasing over the last days. Here
are the counts of two of my servers:

$ grep -c 'H=(netzero.com)' main-200605[23]? main-200606*

main-20060520:230    main-20060520:1

As you can see, counts in May are very low but not always zero. Adjusting the
blocked names for HELO should be enough to stop this.
