I'm trying to connect to a pop mail server using NTLM.
This code:

Pop3.LicenseKey = licenseKey;
            Pop3 server = new Pop3();
            server.SslMode = MailBee.Security.SslStartupMode.Manual;
            server.SslProtocol = MailBee.Security.SecurityProtocol.Tls1;
            server.Connect(txtServer.Text, int.Parse(txtPort.Text), false);
            server.Login(null, null, MailBee.AuthenticationMethods.SaslNtlm, MailBee.AuthenticationOptions.None, null);


works perfect in a desktop application
but does not work when used in a webform with <identity impersonate="true" />
Error: The server has rejected authentication data sent by the client. The server responded: -ERR Logon Failure.
I've tried many different values for
server.SslMode
server.SslProtocol
AuthenticationMethods
AuthenticationOptions

sometimes I get another error meaning that the method is not supported or something like that. But the most of the time I get the error above.

When I provide my login and password instead of null with the all other settings remaining the same the login is successfull

What to do with that?

Probably impersonation is not working as you expected. You should make sure your web application is actually executed under the context of your user account. For instance, check what System.Security.Principal.WindowsIdentity.GetCurrent().Name returns.

See the following link for more information:

Impersonation works as expected.
System.Security.Principal.WindowsIdentity.GetCurrent().Name returns the current user name - the same as in the desktop application

Please try to check "Load User Profile" setting of your application pool. To find it, open the list of application pools in IIS Manager, select the application pool you are using and open "Advanced Settings..." section.

Igor.

I'm using Windows Server 2003
There is no such option in IIS Manager for Application Pool...

We're investigating this, but have not succeeded yet.

We found some hints and are trying them:

Looks like a bug in Windows 2003 POP3 service. SMTP service of the same mail server (Windows 2003 IIS) is working fine with NTLM in Windows Integrated Authentication mode and impersonation.
