Question : Exchange server 2007 large mailing

Hi,

We recently upgraded from sbs server 2003 to sbs server 2008 which include the microsoft exchange server 2007 edition. Every week we send a newsletter to all our customers (about 18.000) the e-mail is about 20kb.  Our server has 12 gb of ram and 1 quad core processor (e5520). Unfortunately when we send the newsletter our internet connections slows down dramatically and we are not able to work anymore since we use internet for most of our work. The mail is generated through coldfusion version 9 64bit by looping over a database and using the cfmail tag.

When looking at the qeue viewer in exchange I noticed that new mails are slowly entering and leaving the queue. In total it takes about 2 hours before all mails are send.

We have a 20mbit adsl connection and we did not experience any problem on our old server which was running sbs 2003 32bit.

Well hope anyone can help me.

Issue resolved by adding the following:

Protected Sub GridView1_PageIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles GridView1.PageIndexChanged, GridView1.Load
       If GridView1.EditIndex = -1 Then
           BindGrid()
       End If
   End Sub
