Unable to send bulk emails through Virtual Server SMTP Relay

Hi All,

I have a virtual server and have setup SMTP Relay through IIS 6.0, I am able to send emails to single recipients and have tried up to five and it works, the main purpose of purchasing this Virtual Server was so that one of our clients could send bulk email, she will maybe send 2-3 emails per week to a list of 1100 people (legit email - not advertising etc) but upon doing so she gets an error saying 'connection to the server was interrupted'.
I have seen this error where the smtp host has got a network wide policy restricting the number of recipients but the hosts of the VPS (WebFusion) assure me that there are no limitations at all.

On the SMTP Relay properties in IIS I have lifted all restrictions etc but we are still experiencing this problem.

Please could anyone help?

It must be a misunderstand. No, WebFusion will not allow you to send 1100 email at a time. It will consider bombing mail. you may be able to send unlimited mail per day in multiple times,  but sending that many emails at a time, you will need to have a big bandwidth. You may look in running your own Exchange server. Check its policy. Here is what it said then you must agree before contracting...
generally accepted standards and codes of practice for use of the internet including NOT sending bulk unsolicited email, mail bombing or impersonating another person

Hi, I have resolved this issue, there is no limitations on our NetSupport account, it was the ADSL provider at our clients office, changing there IP to go through another router resolved this, thanks.

Server Hardware

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
