Thanks for your quick response. I appologize for not being specific about sending the emails. What I meant by does not work is:
When separating by ',' - no emails are sent.
Now I must clarify. I made your suggestion to use comma in the Bcc and it sent the email to everyone I asked it to. Great. So I went back to my original need which is multiple people in the To: field and it does not send an email to anyone in the To: field. So I had two people in the To: field and two people in the Bcc: field. Both Bcc: people arrived, neither To: field arrived.
Thanks again.
