Each of the W32.myparty virus messages which I have seen was approximately 900
lines long. You should be able to force the rejection of W32.myparty virus
carrier messages by adding the following list configuration statement:

        * SIZELIM= xxx

where "xxx" represents an integer value less than 900. I would make it
significantly less than 900.
