Re: Detecting multiple To: headers?

Hi,

Is there a easy way to detect number of recipients of a message? I.e. It
should detect there are 5 recipients in the following message:


  From: Doe John <doe(_at_)some(_dot_)edu>
  To: Person1  <person1(_at_)some(_dot_)com>, "Person2 LastName" 
<person2(_at_)some(_dot_)edu>
  cc: Person3 <person3(_at_)some(_dot_)com>,
      Person4 <person4(_at_)some(_dot_)com>,
      Person5 <person5(_at_)some(_dot_)com>
  Subject: Re: Welcome to our list!

Thanks.
