This isn't as accurate, but it takes 5.36 seconds to execute, vs. 53
minutes and change for the first version.  :-)

#!/usr/bin/perl

while (<>) {
    chomp;
    if (/\ssendmail\[\d+\]:\s+(\w+):\s+.*\<([^\>]+)\>.*User unknown$/) {
        push(@{$log{$1}}, $2);
    } elsif (/\ssendmail\[\d+\]:\s+(\w+):\s+(.*)$/ and $log{$1}) {
        push(@{$log{$1}}, $2);
    }
}

for my $id (keys(%log)) {
    my $to=shift(@{$log{$id}});

    for my $msg (@{$log{$id}}) {
        if ($msg =~ /^from=\<([^\>]+)\>.*relay=[^\[]*\[([\d\.]+)\]$/) {
            print "from=<$1> to=<$to> relay=<$2>\n";
            last;
        }
    }
}
