delimiter used shows up twice in a row. For example blah@@blah.com would, I
believe, return ListLen() of 2 - it wouldn't see there being a list entry
between the @'s.
I've been having this same issue with a project, bogus emails getting past
validation. I haven't yet fully tested this solution... basically the idea
is, do a Find() for an @, then do another Find() for an @ from the position
of the last find, plus 1. If the second Find() returns a value, there's one
too many @'s.
