c# : CDO.Mail problems
light on it. I have and Email dll for my solution. Inside the solution two projects use the dll. An asp.net application and a c# console application. When the dll runs in the asp.net project it sends emails no problem. In fact I can stop the SMTP server and let the emails pile up in the pickup folder. Its' great, I can delete them at will, turn it on and watch them send etc. Now, the same dll used in the console application will send the email if the SMTP server is started BUT if the SMTP server is stopped I get: Could not access 'CDO.Message' object. Failed to connect to transport. ?? Huh ?? I'd really, really, really like to be able to send the console messages into the pickup folder just like the asp.net messages. What's the problem here? I've searched around and I'm not seeing anything about it. I've tried adding the local host to the relay, network service & aspnet account to the operators, no luck :( Any advice is greatly appreciated! Thanks, Ben
Just to be sure were on the same page here, both approaches succesfully send
email when the smtp server is running. The issue is, when the smtp server is stopped the asp.net version buffers in the pickup folder while the console application throws a CDO.Message exception. I will try your suggestions though.

Hello Ben,
The problem seems strange, since asp.net web application can send it but console based application can't. The difference I can think of is the account who is sending the email. Could you please create a separated console based solution to send emails? There are some other steps you can try: Add Read/Write permmissions to Everyone on the Mailroot folder. Change the following line in the code: SmtpMail.SmtpServer = "127.0.0.1" to SmtpMail.SmtpServer = "Blank" which should default to the local SMTP service.

This seems to be a permissions problem. We tried the read/write suggestiong
and it didn't help. Adding the account to the administrators group however fixes everything. SMTP = off, console application email goes into the pickup folder. All we need now is to figure out what permission is necessary. Making the user account an operator on the smtp server didn't seem to help a bit. Neither did power user.

Seems like were going in circles here. The console application will send
email when the smtp server is on. When the smtp server is stopped the console applicatoin crashes unless it is running as an administrative account. I don't see what creating a different console application will do. The one I have is working just fine.

Hi Ben,
Looks like you have touched on most of the issues that you can encounter with SMTP mail. Let me make a couple of assumptions here: I assume that you are using System.Web.Mail in your code in both the ASP.Net application and the >net console application? You mention that the problem only occurs when the SMTP service is not running and the console application tries to send mail.. I Have a couple of suggestions there but there is one additional thing that we need to determine, what version OS are you running the code and the SMTP server on? Are they both the same machine or are we also trying to send via port? It sounds as if the code is running on the same machine as the SMTP server. Here's a couple of things that we can try: [quoted text, click to view] > Run filemon on the machine, just to see if we are getting any permissions errors on the pickup folder, I doubt it, but better safe then sorry.- You can of course get filemon from http://www.sysinternals.com [quoted text, click to view] > You do mention that adding the account to the administrators group seemed to resolve the issue. If that is the case, I would really look at this KB article, which may be the issue that you are seeing: 816789 Read Access to the Everyone Group Is Removed After You Install Exchange http://support.microsoft.com/?id=816789 It discusses problem with access to the IIS metabase, this also applies if this is an Windows 2000 server with the latest service packs and updates. I hope this helps, please let me know your progress and if you encounter any issues.
