That gets me closer, I think.  It's concatenating the number of messages, but it's a start. Thanks.

I do this kind of thing on a fairly regular basis with a Perl one-liner:

perl -ne '($email, $num) = split; $tot{$email} += $num; END { for $email (keys %tot) { print "$email $tot{$email}\n" } }' < yourfile
