That's what I ended up doing... plugging all 174 addy's into
/etc/aliases. I was hoping I could use a wildcard to handle it, but have
since learned that magic of that sort requires hacking sendmail.cf
directly. I'm loathe to do that. It's a pity that few web sites allow
entering a plus-address'd email - that would have handled it neatly. Too
many squeeze out the plus sign *sigh*.
