Actually I think my spelling is fine. The line in question is:

print BLAH "Effective-Content-Type " . $mail->effective_type . "\n";

It has been a while since I wrote this. The script runs fine for 98% of the mail I get just two messages a day that I get from the system about security of the box cause the error message that I quoted. So I looked into my I thought $mail->effective_type was valid. My impression of what the documentation say is that $mail is a subclass of Mime::Entity. It turns out that on further reading of the Mail::Audit docos I understand that it is only a subclass of Mime::Entity if appropriate. So basically something about these emails say that it is not appropriate to subclass Mime::Entity so the call to $mail->effective_type is not valid

If you are wondering why I do

print BLAH "Effective-Content-Type " . $mail->effective_type . "\n";

I am trying to work out how to suck all the attachments out of an email and save them in a directory separate from the message
