My ISP, Orange, will not allow me, i.e. blocks me, from sending a single email to more than 19 recipients at once. I use WindowsXP and Outlook Express. I know that BT Internet, Plusnet and many other ISPs allow one email to be sent to many more recipients at once. Indeed a friend, who uses btinternet, recently sent me an email which I could see was sent to 87 recipients at once. Is there are any free software available to download which would enable me to get round Orange's restriction and send out an email, with attachment, to up to 100 recipients at one go? I gather that the software would have to carry out "tarpitting", that is sending the email out in small batches of recipients. I do NOT want to have to change ISP.
