Sending Email Using System.Net.Mail Only Works To Internal Addresses
Feb 1, 2010
I created a web form to send emails and using a class to perform the task. The process works well for all internal email addresses but will not deliver to external email addresses. I am not sure if I missed something in the code to send to external address.
VWD 2008 Express. Visual Basic. I use the following routine (XXXXX have replaced sensitive data) to try to send an email message to mutiple email addresses. It only sends to the first email address in the comma-delimited list. How can I send the message to multiple email addresses?
I'm using this code for sending mail message for invite a friend, And I'm getting this error that I do not understand why Value cannot be null. Parameter name: from (I do have a from parameter as far as I understand )
I have developed a colleg web applicaition. I have used my gmail account as my smtp server to send back to the client passwords from "Password recovery" link. The problem is that , I am able to send messages only from my gmail account. I want to know whether I can send messages using different e-mail addresses of the clients retrieved from the database instead of sending the mail using my own.
I have small project (C#, Visual Studio 2005, .NET 2.0) that runs a SQL stored procedure and creates an e-mail from the result set. The "To," and "CC" fields are populated from the results. My procedure will only return a single "To" addressee but there can be multiple CC's. The stored proc is written to concatenate them all into a single string, e.g. "[URL]" etc. So..... in my project I am using System.Net.Mail. When I try to code "myMessage.CC.Add(read.GetString(3))" I get the following error:
The specified string is not in the form required for an e-mail address. In .NET 1.1 using System.Web.Mail this worked just fine. The change to System.Net.Mail resulted in this error. I really can't modify the stored procedure so I need to find a way to get my application to populate the CC field with the complete string returned by that stored procedure. How can I do this? The e-mail addresses are dynamic and I can't hard-code them.
i am sending email to the users using smtp client and MailMessage class.
i have been adding the addresses of multiple receivers in the to property of the object of MailMessage class. the problem is that the receiver can see the email addresses of other receipents. is there any way to hide the email addresses of other receipents.
i mean setting some property or something like that. otherwise i will be left with only option to send individual email to the users.

getting the above error when sending mail from asp.net 2.0
I've built several websites on my local machine and have successfully tested sending mail from within the application, but suddenly the mail won't go anywhere! I have a try-catch routine, and I'm getting the message that the mail has been sent successfully but it's not going anywhere. This is the code that I've used in a test page - the html page has a button and a textbox and nothing else. I've imported the system.net.mail namespace.
I'm getting the 'Email Successfully Sent' Message but I'm not receiving the email. I don't think I've changed any settings to stop the emails from going.

I have this code up in a live windows 2003 sp2 server. I use Hmailserver as mail server and I am not sure if this cause the problem.I am able to send email consecutively 2 time no problem, but it is always the 3rd time after I would get this error: Unable to read data from the transport connection: net_io_connectionclosed. I wait for 30 minutes I am to send email again, but only the first 2 time works. Here is my code can someone please verify my code and see if anything is wrong with it.
Anyone know how to do this? Using my own mail server is easy, but in case there's something wrong with it or it ends up on some blacklist, I would like to use the receiver's mail server. There will only be one to: for each mail (it's a validation function to a sign-up).
my first code below works, but my second doesnt do anything.obivously the first code just posts the html as text, but the second code does absolutley nothing at all, no errors, nothing, just no mail at all :S
