Does anyone know how to prevent a user from entering a Mail List in the To: or Cc: block in a message. I'd like it to only be able to be put in the Bcc: block to prevent those horrible floods of "Reply to All".
I am using Pocomail; I customized the "Send" dialog and removed "CC:". I only have BCC. Ofcourse I could still accidently put a bunch of emails in "To:", but I always use "BCC:" if I have multiple recipients.
I doubt there is a way to prevent entering multiple adresses in the "To:" field, except if the program has a feature like that. Maybe you could disable the entire "paste" functionality of Windows.
