Maybe this has been fixed already?  I'd never heard of it, and it does
sound scary, so I tried to replicate the behavior using several
configurations (which @, which "@", which \@, which "\@") with my
majordomo.  But they all seemed to work ok, each time majordomo responded:

  >>>> which @
  The string '@' appears in the following
  entries in lists served by Majordomo@cutter.com:

  **** No matches found

I'm using Sendmail 8.8.5, majordomo 1.94.4 (rev 1.56).
