We are developing an ASP.NET 2.0 (C#) application, and I'm having troubles
sending e-mail from the server when accessing the web site from a separate
client computer.
Here's some details:
Server and client computers both in the same workgroup
Logged into server as local Administrator
Logged into client as a local user that is only in the Users group on the
client computer
The local user on the client is also defined as a local user on the server
with same name and password (and only in the Users group on the server too)
Server is Windows Server 2003 running IIS 6.0
Client is Windows XP Professional
ASP.NET 2.0 (C#) web site - intranet only, not a public Internet web site
Web.config snippet
<system.web>
<authenticati on mode="Windows"/>
<identity impersonate="tr ue"/>
</system.web>
..aspx code-behind code snippet
string fromEmail = "do********@tes tingsendemail.c om";
string fromDisplayName = "Testing SendEmail";
string toEmail = "pe****@company .com";
string pathAndFile = @"D:\Temp\testi ng.log";
string exceptionInfo = "Testing SendEmail";
System.Net.Mail .SmtpClient smtpclient = new
System.Net.Mail .SmtpClient();
smtpclient.Deli veryMethod =
System.Net.Mail .SmtpDeliveryMe thod.PickupDire ctoryFromIis;
// For smtpclient.Host , I've tried "localhost" , I've tried
System.Net.Dns. GetHostName(),
// and I've tried not setting the property at all
// none of these work
//smtpclient.Host = System.Net.Dns. GetHostName();
// For smtpclient.Pick upDirectoryLoca tion, I've tried not setting it
and I've tried
// explicitly setting the path to the IIS pickup folder
// neither of these work
//smtpclient.Pick upDirectoryLoca tion =
@"C:\Inetpub\ma ilroot\Pickup";
// For smtpclient.Port , I've tried not setting it and I've tried
explicitly setting it to 25
// neither of these work
//smtpclient.Port = 25;
// For smtpclient.UseD efaultCredentia ls, I've tried not setting it
and I've tried
// setting it to true
// neither of these work
//smtpclient.UseD efaultCredentia ls = true;
System.Net.Mail .MailAddress from = new
System.Net.Mail .MailAddress(fr omEmail, fromDisplayName );
System.Net.Mail .MailAddress to = new
System.Net.Mail .MailAddress(to Email);
System.Net.Mail .Attachment attachment = new
System.Net.Mail .Attachment(pat hAndFile);
using (System.Net.Mai l.MailMessage message = new
System.Net.Mail .MailMessage(fr om, to))
{
message.Attachm ents.Add(attach ment);
message.Body = exceptionInfo;
message.Priorit y = System.Net.Mail .MailPriority.H igh;
message.Subject = "Testing SendEmail";
// EXCEPTION is throw here trying to call the Send method
smtpclient.Send (message);
}
attachment.Disp ose();
The exception details are: System.Net.Mail .SmtpException: Cannot get IIS
pickup directory.
From the client computer, I can navigate to the site and do whatever without
any problems. But, when the site tries to send an e-mail from the server
for the session started by the client in the scenario described above, it
fails.
Basically, this is supposed to be an exception notification thing.
What's wrong? Am I missing something? How can I make the above scenario
work?
Thanks.
