Sending bulk email

Hello,

I'm trying to send an email for over 65,000 users via an asp.net application with Net.Mail.SmtpClient.

However, I'm getting this exception:
System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

I have updated web.config to
<httpRuntime executionTimeout="400000" useFullyQualifiedRedirectUrl="true" maxRequestLength="614400" requestLengthDiskThreshold="10240" />

Any ideas?
Thanks!

Over 65000 users? Are they really asking for your mail or are you trying to write a spam-bot?

ISPs often limit the number of emails you can send per day or per hour.  I've seen anywhere from 25 per hour to 1000 per day.  After that you're blocked until the next time period.  That is done to prevent their servers from being blacklisted and unable to send and receive email.

Many of us recommend bulk email services like Constant Contact or Aweber who have their own servers and connections and specialize in sending email.
