Hi all.

I have a client for whom I have programmed a web application with
subscribers. He wants to give ability to his subscribers to send mass
emails to their contacts through his web application. Right now, the
site is on a IIS server running Windows Server 2003. And I'm using
just standard SMTP to send emails through his web application via a
CDO asp script.

I'd like now to set-up mass emails for him, but I am concerned about
the following:

1) I don't want his emails to be flagged as spam especially since his
subscribers may be sending a lot of emails and we have no control
over
to whom they're sending it.

2) I don't want his IP to be blacklisted either and then all
subscribers won't be able to send emails.

3) I don't want to overload or slow down the server if so many emails
get sent everyday...

These are the kind of questions I have and I'd like some reall expert
advice. Should I set up emails on a seperate server? should I use
some
software like MS Exchange? etc... etc...

Any help would be greatly appreciated.

By the way, my client would be ready to pay someone to help us set
this up properly.

Thanks in advance

Make sure your system is set up to use two-way verification, so the
recipient has to request the mailings and then confirm via an email your
server sends out that they want to receive the mails. That way you are
covered against people who forget they subscribed and you also are sure your
messages are going to the right person.

Most RBLs are generated by using spam-traps. That is, addresses which have
enver been published. If your system is sending to legimiate recipients who
requested the messages, then you should be safe. If some other RBL lists
your server due to recipient complaints, you will be able to show them proof
from step 1 that the email was requested.

I guess that is more up to you to set some limits on your software.

this one requirement bothers me... if you have no control over who the
subscribers send their bulk email to, then you have no way to avoid spam
traps or other anti-spam filters. If users are restricted to sending to
other subscribers, and subscribers have to acknowledge that the accept mail
from other subscribers then you should be safe.
