Can you see what I have wrong in all this? Thanks.

Hi Featheriver,

I can only guess as I don't know the setup or rules of your ISP's mail serer, but my guess is that [email protected] is not a valid "from" address; instead of your user name, try your real address; e.g. the one that starts with featheriver.

BTW: you may want to edit your previous post and remove references to your real e-mail address and mail server; never a good idea to post these details on-line....
