This code scares me a bit: 
        my $oct_mode = sprintf "%lo", $dec_mode; 
        if (-O $private_dir and ($oct_mode == 40700)) { return } 
        elsif (-O $private_dir and ($oct_mode != 40700)) {

You are probably lucky that 40,700 decimal is a nice integer value. Why not leave it at octal? 
    if (-O $private_dir and ($dec_mode == 040700)) { return }
    elsif (-O $private_dir) {

And that value isn't really a "decimal" mode. It's the value of "the mode", which usually prints out as decimal. Internally, it's binary, unless you have a BCD-coded machine (not likely {grin}).

The other scary code here is your use of mailx. While the content of your message cannot possibly contain a line that begins with tilde, you might get complacent some day and permit such a line, and then you can say buh-bye to security. Get in the right groove by looking at Mail::Mailer pretty durn quick.
