When you personalize that give the date and IP address of the request.

this sounds reasonable
but is there anything at a system level that can be done to make
emails less likely to be classified as spam?
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?
these all sound very reasonable. However, we use the same IP for several virtual
hosts ie we have more than one domain name so the reverse DNS is not clear to
me. Is the from address inspected for comparison with the RDNS ie if I claim to
be sending from xxx.com should my RDNS point back to xxx.com? Presumably I can
have only one IP-->domain ptr. I suspect it will be easier to set up the front
end machine as that is supposed to be for the same client.
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".)
OK that's good.
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.

this isn't automatic, the sales people manually enter all the details. The
attached document is what the application generates and then the combined email.
