my $fh = IO::File->new($MAILBOX) or die "unable to read mailbox '$MAILBOX': $!"; my $mail; { local $/; $mail = <$fh>; }
is probably better written as
my $mail = do { my $fh = IO::File->new($MAILBOX) or die "unable to read mailbox '$MAILBOX': $!"; local $/; <$fh> };
That way, $fh gets automatically closed as soon as you're done reading it, and you declare and assign $mail in one step.

Also, if it was me, I'd probably sort the email addresses when printing them.

A word spoken in Mind will reach its own level, in the objective world, by its own weight
