Configuration :: External Mail Not Sending - Exchange Server As Host?

Aug 4, 2010

Using Visual Studio 2010 Web Developer Express ( code) with SqlDataSource to SQL Server 2008.

I am developing an email form to my users to send email to vendors with an attachment. The aspx page is quite simple -- 2 dropdownlists, a fileupload control, and a send email button. They select their store (which populates the "From" address of the email). They select the Vendor (which populates the "To" address of the email). Then they browse for the file attachment and click "send email"

I just can't get outside emails to send. I do not get any error messages in the web page. If I change the email1 and email2 in SQL Server Vendor table to an email address (mine) within the domain I get the emails. However when I change to a test hotmail, yahoo, or gmail accounts the emails never get there. I have absolutely no confidence that my programming is correct so before I go to the IT Manager again I really need to verify I am not missing something on my end. We did make a change on the exchange server to allow anonymous email from my webserver and still didn't work.

Here is my webconfig file:


Here is my code-behind:


Here is my aspx page:


I have been playing around with the programming for 2 days making 1 change at a time then testing to see if external email is sending. I'm going quite crazy at this point ...

I've put in breakpoints and debugged. Below is the output from the latest test. I have concerns about the clientDomain being "SQLSVR" which is my webserver name, our domain is "". As well as the line "Domain" that is blank " " under NetworkCredential. Also the line TargetName "SMTPSVC/exchangesvr"
