Hi there

I have a mail programme that is used to send email newsletters to subscribers. This is currently sending about 7000 emails out of a 20,000 list and then crashing with the following message Response: 421 Connection limit reached.

I have searched the MS website and the internet in general but found no mention of this error anywhere. The Exchange help is not very helpful either. The only area that lookged kind of hopeful was MTA but I don't really know what this is. I am also pretty new to Exchange Admin so if I need to tell you anything else just ask.

All thoughts and suggestions appreciated.
