sending email using C# - exited with code 0

[minishilpi]

I have a question - I have this code below to send an email and I have referenced the Microsoft CDO Library 2000.
It doesn't throw any exception in the console window. It goes throughout the code successfully, but I do not receive any email.
When I execute this code to send email, it gives the following error -

Thank you for your help!

I'm glad it's working for you in the wild.
It's going to make testing while developing difficult though.
For development testing purposes would recommend using a different SMTP server than you are currently using...or look into fixing it.

Cheers!

Pretty interesting. I thought that by default SMTP messages timed out and generated Non-Delivery reports after 48 hours, but I guess I could be wrong. I think MS-Exchange does this by default.

Sounds like this is an email routing issue. Determine what domain you are sending email to and grab one of the email addresses, and the servername that you are sending from (you can't use localhost).

Then do this from the SMTP mail server. You should get a list of responsible servers for the recipients domain and then you can check connectivity to those mail servers that are finally listed.

1) NSLOOKUP (type from command prompt and press enter)
2) SET TYPE=MX (enter),
3) somedomain.com (enter)

then try from a different command window (but on the SMTP server itself). You are going to send a simple test email via Telnet.

1) TELNET hostname 25 (enter)
(where hostname is one of the results from your NSLOOKUP)
2) HELO yourservername (enter)
3) MAIL FROM: <someSMTPAddres [e-mail]> (enter) (this should be a valid email domain on your localhost or within your organization)
4) RCPT TO: <someuserthatyo uaresendingemai [e-mail]> (enter)
5) DATA (enter)
6) Subject: Some Subject (enter)
7) Some text in the message (enter)
8 . (enter)
(the period in the blank line means end of message)
If you get a message accepted message, your message is on its way.

Anyway, if there is an error anywhere in your typing you will get a 500+ error you have probably typed something improperly, or the destination server is not accepting email from you.

Let me know what happens.
