If you read the array into a scalar $contents then just split on the
first, standalone blank line.

my ($headers, $msg) = split(/^\n$/, $contents);

or you can take an array slice from the original @lines by finding the
first element with a just the \n

$looking = '1';
$n='0';
while ($looking){if ($lines[$n] =~ m/^\n$/){$looking='0'}}
$msg = @lines($n+1,$#lines);

or.....

perl is phun
