Use Localhost SMTP Server For Emails But Route It Through Exchange Server 2003?

Jan 7, 2010

I have developed an enterprise application in ASP.NET that sends emails using localhost SMTP server on the same box as the IIS web server for the ASP.NET app.

So right now any email sent from this ASP.NET app would hit internet firewall of the enterprise and then be directed to the right destination email address.

I was hoping to not hit the internet firewall of the enterprise, but hit the Exchange Server of the enterprise.

So the situation I am aiming for is: ASP.NET APP ===> Localhost SMTP SERVER ===>EXCHANGE SEVER 2003 ===>SEND OUT THE EMAIL

rather than ASP.NET APP ===> Localhost SMTP SERVER ===>SEND OUT THE EMAIL

So I still want to use the same mail configuration in my ASP.NET app of localhost as SMTP server, but just want the email to first go through Exchange Server before being sent out.

Configuration - Multiple SMTP Servers Or Update The SMTP Object Server Information At Runtime?

Nov 5, 2010

The question: Is it possible to configure multiple SMTP servers or update the SMTP object server information at runtime?

Description of problem: The site I'm working on has a few pages which send emails. Our site is using Gmail so even though it's a custom domain our email is sent out though Gmail SMTP servers.

Some emails come from the system and some emails come from users in certain groups. I have an SMTP server configured with the admin email for the system e.g. This works fine and when I get the email it shows from admin@mysite.comOne of our user groups let's call it "groupA" has an email configured on our domain i.e. When I send the email and specify a from address for the MailMessage object as it still shows up in my outlook as coming from I did a little further testing and if I specify both the from address and the ReplyTo as it will show as but when I choose reply in outlook it shows My best guess is that Gmail is overwriting the From address with the SMTP user to prevent email spoofing.

I found this: but it won't work for me since group A, B, and C all need to send emails from the same page.

Exchange Emails Within Web Application?

Jan 9, 2010

Inside my ASP.NET application, I would like to add an iframe where I can display the emails from our exchange server for the logged in user. The web application uses forms authentication with custom authentication (passwords are hashed and stored in db).

Is there a way to show OWA within my web app without prompting the user for password (OWA uses windows authentication)? Can I use impersonation in some fashion or establish a trust between my IIS server and the server running OWA?

Security :: Service Call From Application Fails In Server 2008 (worked In Server 2003)

Jan 5, 2011

We have a web application that makes a call to a remotely hosted ASMX service that worked in Server 2003 under IIS6. We are now migrating it to a Server 2008/IIS 7 setup and it doesn't appear that the application makes the call to the remote web service anymore. We ran Wireshark and don't see any traffic to the service URL. It seems to throw a 404 error without trying to connect.

Is there some security policy or restriction in Server 2008 or IIS 7 we need to set to allow an ASP.NET application make a call to a remote web service? We are using Network Service as our application pool user, but also tried using Local System as a troubleshooting step. In addition, the same code works if run from a console application on the server instead of the web application.

Is there some setting under IIS7 or server 2008 that would be causing this?

Configuration :: Can't Get Older Server 2003 Web Applications To Run On Server 2008

Jun 25, 2010

I'm a total noob to anything ASP. I'm a web designer for my county's sheriff dept. and I don't create dynamic pages because out content doesn't require it. In fact, I'm still quite new to web design. The programmer who created the apps has zero experience with IIS7. These apps are designed to run on our organization's intranet server. I'm not having any luck with getting these sites to run properly. I have the sites created with the proper directories. When I click in the right-hand column of IIS Manager to browse to the sites, they launches but don't function as they should. They load up like static pages. I installed .Net 1.1 hoping that would make a difference but it had no effect.

Web Forms :: Using Localhost In SMTP, 2.0

Im trying to follow the directions within this page to configure my smtp server, I have windows 7 and iis 7.

Im having issues with the code behind:

////////////////Below 4 lines are for testing in windows 7. Comment them before compiling for production.//////////////

////////////////Host and DeliveryMethod are set for SMTP4Dev.exe to receive the mail//////////////

Is this suppose to be in the code behind page of the password recovery page? or in a separate class? When pasting in the code behind I get an error under the word system and smtpmail? Do I need to include an imports statement: imports

Web Forms :: How To Copy A File From The Web Server To The SMTP Server

Apr 23, 2010

I need to copy a (WAV) file that I have just posted to the Web Server (successfully) over to the SMTP server for additional processing. I am confused about the process. Here is what I do now:

1. Post the file via "http POST" from the client to the web server.

Here is what I would like to accomplish:

1. Post the file to the web server

2. Copy the file from the web server to the SMTP server.

I am experiencing a "brain block" which I get too often and cannot visualize the processes. What should I write on the web server as a method to grab the newly received file and send a copy on over to a specific directory in the SMTP server (MailServer is the SMTP server and the physical directory is "c:/TempMessages". Do I need to run IIS on the SMTP server and create a virtual path??

WebMatrix :: Testing Emails Sending (SMTP) Under IIS7 Express

I don't have web server account yet so I must test my applications with the Web Development Server under VS 2010 with C# but I read that I couldn't send emails under that server but I also read that I can send email with IIS7 Express and that's the main reason why I've install Webmatrix. Maybe someone can confirm this. So for the moment I am redirecting my emails into a local folder and it is working perfectly. Here is part of the code I've add to the Web.Config for doing that.


As you can see I am redirecting the emails to the D: emp

Configuration :: "Server Error In '/' Application" When Run An Aspx File On Server Windows 2003 With IIS 6.0

Aug 9, 2010

I am trying to run an aspx file on my server windows 2003 with IIS 6.0. I get the following error. Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local
server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
