I wonder if their spam filter will allow you to make an "exception" by keying on the TO: field instead. That would hopefully allow users to enter a filter for TO: such as [log in to unmask], allowing their list through. Probaly not, but it may be an approach we can suggest to them, if they are amenable to suggestions. bill __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
