The most crucial thing is the status of IP of the host sending the mail o Does it have a proper DNS PTR (reverse DNS) record? o Are you using SPF or DomainKeys to show that that IP address is authorized to send mail in the sending domain's name? o Do you have working postmaster and abuse addresses for the domain you are sending from? o Do you have a static IP address? o Are you clear of any major blacklists? o Can you demonstrate that every recipient really did request the mail? Each of those are far more important than whether you attach a PDF. (By the way, say it's PDF or even Adobe's PDF, but not "Adobe Acrobat format".) > I assume that spammers try very hard and fail, so is this kind of > email application effectively dead in the water before it starts? Automatic mailing is fine. What is important is how the email addresses were acquired. -j
