I'm e-mailing a message from my application to myself, I don't quite understand how to do this, but I did think I had finally gotten it right -
[Code]...
I've got that code in a try/catch statement and it shows me via a MsgBox the error "Failure sending mail".
I want to send email from vb.net 2008. All of my code is correct but i don't know why the message comes "Mail Sending Failure"
here is my code
Imports System.Net.Mail
Public Class frmMailing
Dim SmtpServer As New SmtpClient()

I'm trying to create an application that sends an email to an smtp-server. The server is not set fixed, but will be looked up according to the domainpart of the email-address where the email should be sent to.
[Code]...
It would be quite useful, to know if the message was accepted by the mailserver and the message was successfully sent. What I am able so far is, that I can get the SMTP-Server error code (if there was an error (StatusCode 5xx) by using the System.Net.Mail.SMTPClient Object and its SendAsync Function. There, if there was an error, I get an Exception-Object in the Callback-Event of the SMTPClient
I'm well aware that not every mailserver will tell me if the mailaccount truly exists and then reject my mail with an errorcode but instead just accept the message and then delete it. Therefore I would be grateful for another Method to check if the mail was sent (note: not read, that would be the read confirmation)
The final purpose would be: Try to send an email to a recipient using it's domains mailserver and if it fails, proceed according to the errorcode (user does not exist -> abort / mailserver did not respond -> use another mailserver if available).
I have an issue where emails sent out via the SmtpClient class in .NET go directly into the outlook junk mail folder (Outlook 2003 and 2007). If I send the exact same email (same body, same subject, to and from the same accounts as I use in .NET) from Outlook itself, it will come in fine and not be marked as junk mail. The only difference is the extra headers that Outlook appends to the email when it is sent directly from Outlook.

The exact error I am getting in Visual Studio 2012 is:
error BC30456: 'Dispose' is not a member of 'System.Net.Mail.SmtpClient'.
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Port = 25
[code]....
This should be an obvious error. You would think I was using .net framework 3.5 or lower as Dispose() was only added as a member to SmtpClient in .net 4.0. However, I am using 4.0!In the website property pages it states 4.0. Is there somewhere else that I need to set as 4.0?
I am about to put my fist through my monitor!!! I have been working on this for the better part of 2 days. Here's the issue: I'm in an Enterprise environment and am writing an app that will shoot off small emails. I got the settings I needed yesterday and got everything to work 5 times in a row! Then, I went to another task for a little while and came back to the email portion and ran another test and it never worked again! I've written and re-written my code 100 times. I can't get it to work. Here's one version of my

I am writting a program to sendout email by reading from SQL database and get the data out for the email information: To, From, subject, body and attachment. I am importing system.net.mail. But My email will send without any attachment but it will not send with the attachment. It give me this error: Logon Failure: Unknow UserName or bad password. However if I send the email with the attachment that is not get from the sql database. It will send just fine.

I am trying to send email messages from a Windows based Visual Basic application. I am using Visual Studio 2008 and .NET 3.5. The IP address in the config file is correct. But this gives an error message: Failure sending mail.

This is the code I tried but it aint working right, shows failure sending mail, unable to connect to remote server. I am using internet via bluetooth through my gprs enabled cellphone.
I was trying to follow a code example I came across the net for programmatically sending email:

I'm using the MAPI code by Dave Brooks.I am attempting to programatically send out a Crystal Report that is generated.When I run through the code without threading everything runs fine. The problem is when I use threading I get the return error "General MAPI failure [2]".I have never used threading before and understand that there are dangers involved. Can anyone provide any insight into this issue? NOTE: I've removed exception handling to make the code clearer.[code]
View 1 RepliesI want to send an email that contains an attachment via vb.net and smtp. I used gmail as smtp server. This project works correctly when the size of attachment size is lower than 1Mb. When the size of the file is bigger than this size it makes an error. The message is this: "ContextSwitchDeadlock was detectedMessage: The CLR has been unable to transition from COM context 0x652fd8 to COM context 0x653148 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."I extended the timeout period but this message is shown.

I've been able to create and send an e-mail using System.net.mail. But it appears that the message isn't being sent until the application closes. This causes two major problems for me.1) When the user tries to send a second message, I get the following error: a generic error occurred in GDI+. I believe this is caused because I'm creating and sending a screen shot. If I take out the screen shot the error goes away. The screen shot is nice but not necessary. I can work around it, if I have to.
2) I am using the e-mail to provide notification that a process has been completed. The sender may continue to do other work while in the application -- including sending an e-mail to another recipient.
What do I need to do to get the e-mail to be sent before the application is closed?
I have been searching for the answer to this for quite a while but none answer me exactly. Here is my problem, I want my user to be able to send an e-mail by clicking on a button "Send" and for this e-mailk to take the e-mail address from a text box and the message from a text box (Subject can be hard coded as it will always be the same) but I need to do it without using SMPT protocols as I don't want the user to have to input lots of information regarding their e-mail etc. Is there any way to do this.
