I see. Are you saying that you are connecting via your parents' ISP but using
iglou.com's smtp? I occasionally check and send email with my Palm OS cell
phone. In that case I can dial up either to SprintPCS.com or netreach.net
(my regular ISP). If I dial up via SprintPCS.com, I can't use
smtp.netreach.net because smtp.netreach.net would bounce it as an illegal
relay. If I dial up via SprintPCS.com, I have to send via
smtp.sprintpcs.com. But either way, my ¨From:¨ address is @alexion.com, and
I rarely use sendmail so I am always using one ISP's smtp server or another.
Are you saying SPF would reject any alexion.com mail as forged since it is
coming from another domain's smtp server?
