a)  You're complaining to the wrong mailing list.  Issues specific to a
particular package should be addressed to that package's dedicated mailing
list; in this case, that would be majordomo-users@greatcircle.com.

b)  Majordomo _does_ strip out the comments before comparing addresses.  I
don't know what the problem is, but that's not it.

c)  Just what do you expect Majordomo to _do_ to prevent this situation?
