Ah...with that context, I might try to approach the problem
differently. If you don't mind newlines being added when more
than one email was on the same line, I might do something like

:%s/\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)/\r&\r/g
:v/^\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)$/d

The first one puts each email address alone on a line, and the
second one deletes all lines that don't have an email address on
them. Given your example, one might also have to add "\c" to
your pattern to make it case-insensitive (your regexp only finds
uppercase email addresses).

If you need to keep emails on the same line back together, it
might take a little more work.
