VS 2008 SmtpClient And Outlook Junk Mail
Nov 5, 2009
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.

Not sure if this is the right place to ask this so sorry if its wrong. I recently developed an 'In-House' Messaging system so our Receptionist has a very easy/quick way of sending phone messages to people formatted nicely and delivered to their Inbox in outlook. All the messages come from reception@our.domain and all messages are delivered to firstnamelastname@our.domain

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).

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 have a piece of code which sends email with an attachment from my application. The code uses MAPI to send the email. It opens up a new email message so the user can add to the email message, and then the user clicks send.The code works fine. However there is one small problem. The email that the code opens, is always in Microsoft Outlook. Sometimes the application's user has Outlook Express set up as the default client, but my application always opens the new email message in Microsoft Outlook. (Outlook 2003. In the one user's machine that has Outlook 2007, everything works fine and the email opens up in Outlook Express.)As I searched for a solution, I saw this problem posed many times in various places on the Internet, with no solution (or none that worked). I did try several suggestions which involved creating registry settings and registering some dlls.

I am using the System.Net.Mail namespace to create and send email messages. Everything was working fine until a couple of QC members of our team noticed something strange.
If they send emails from within my application and then leave the application open for a while (perhaps working on other tasks on the PC), when they try and activate my application again, it appears to be hung. The CPU is not pegged and everything appears to be normal in the task manager. We narrowed it down and it appears that this issue only manifests itself when MS Outlook is also opened and connected to a server.
I was playing around with process monitor, but nothing I saw was really glaring. I actually started deleting some threads on the PC and eventually my application became usable again.

I'm very new to VB and .Net. I'm using VS Express 2010 to write an application, so far its great and I've managed to get everything working they way I want it. I'm now trying to add more advanced features, (e.g the app has some TextBox's that the user enters required information and it generates an e-mail based on a template I've coded. At the moment this just copies it to the clipboard and the user can create an e-mail and send it manually.)
I want to add the functionality for the app to automatically open up an Outlook mail and pre-populate all the information, I've managed to get this working for Outlook 2010. I done this using the following codes.
Dim MSO As New Microsoft.Office.Interop.Outlook.Application
'Create a new Message object
Dim msg As Microsoft.Office.Interop.Outlook.MailItem
'Compose the Message

got a little application that uses MAPI Control to:
extract e-mails from local outlook account,
-> checks Subject Field complies,
-> ->creates a .txt file from e-mail's body for further reference.
during runtime, Outlook MSG (attched jpg.. ) pops. and asks to user allow MailBox Access.
AS Application is meant to run in background, Looking for a way to have no user interaction during runtime
i.e.
->access the above e-mail from the server.
->create privileges programmatically. (?)

How To Design an Outlook AddIn to capture New Mail Event In Vb .net. I've been able to use code to read the number of unread email messages in an Outlook Inbox. I'm trying to design a plug-in which will be more functional and Catch whenever the SendReceive event is fired. Can anyone point me in the right direction?
I am writing an outlook addin that is supposed to check for any new email messages. I am trying to attach to the send/receive action that occurs within Outlook (Either auto S/R or manual S/R). I have read on a forum online that there is no such event as a Send'Receive, how ever you can use a NewMailEvent. Can anyone demonstrate how this could be done in VB 2005/2008? I would like the Plug-In to check everytime Outlook receives new email.

I got the following code from codeproject.com:
Dim objOL As Outlook.Application
Dim objNS As Outlook.NameSpace
Dim objFolder As Outlook.Folders
[Code].....
Now, I got as far as making the default folder the Inbox. What I would like to do is to extend the functionality by retrieving only a specific person's emails and extracting and saving whatever attachments he/she sends. Also, I get the following error when the code reaches the Dim Atmt as Outlook.Attachment part: Public member 'Attachment' on type 'Object' not found. I need this function to retrieve the attachments. I've tried different things, but nothing's worked.

When I send a mail from my external program through Outlook, then I get the security warning.
I've tried bypassing it with secman and redemption, but both these tools doesn't allow the app to be "Any CPU".
I need the app to be Any CPU because it must be x64 on client and x86 in design (since designer doesn't allow inherited forms on x64).
So how would you go around Outlook security?
Should I write some kind of TCP-listener-Outlook-Addin and then send a TCPIP from client with mail info?

I have an issue with the System.Net.Mail.SMTPClient class - when it sends an email via the Send method it does not seem to send the QUIT command after sending the email so the connection stays open indefinitely (or until the SMTPClient instance is disposed of by the garbage collector) as far as I can tell.I thought oh well I must just need to call Close or Dispose on it but neither of those methods exist This is very basic, standard SMTP server usage - every server should send QUIT after it is done sending the other commands used to transfer the email, otherwise the remote server keeps the session open (and some servers have a limit on how many sessions can be open at a time or how many emails can be sent per session) so this could cause some serious problems.
Am I being daft or does there seem to be no way to make it do what pretty much every other SMTP client in the world does? I found a Microsoft Connect topic that had been created about this but it was 4 years old and the response from MS was that they would probably include something in the next version of the framework... which is what we are now on
