Good day,

 

 

 

I recently upgraded a server of mine with a simple ASP site to server 2008 and it sent emails from exchange 2003 with no problems after the upgrade to server 2008. Here is the code:

 

1.private void SendTextMessageCC(string fromAddress, string fromName,

2. string toAddress, string subject, string body, string ccAddress)

3. {

4. try

5. {

6. MailAddress fromAdd = new MailAddress(fromAddress, fromName)

7. MailAddress toAdd = new MailAddress(toAddress)

8. MailAddress ccAdd = new MailAddress(ccAddress)

9. MailMessage msg = new MailMessage(fromAdd, toAdd)

10. msg.Subject = subject

11. msg.Body = body

12. msg.CC.Add(ccAdd)

13. SmtpClient client = new SmtpClient("deexch1.****.com") // localhost

14. client.Send(msg)

15.

16. // msg.DeliveryNotificationOptions = 0

17. // 2 means OnFailure was 1 but that was error 0 okay means "None"

18. }

19. catch (SmtpException s)

20. {

21. lblSuccess.Text = s.Message

22.

23. }

24.

25. }

 

Now this week I upgraded my Exchange Server to 2010 (Server 2008) and changed the smtpclient string accordingly above to SmtpClient("draw-mail1.****.com"). It will not send emails from the server, but when I run it from local host it sends them without a problem.

 

When I send from an XP Machine it sends fine to the new mail server. It is something with IIS and Server 2008.

 

 

Any Help? I am stumped.

Make sure you set the server to run scripts in 32bit mode. That should fix the problem.
