System.Net.Mail ignores Sender address when delivery method is SpecifiedPickupDirectory

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :ASP.Net

Has anybody else had an issue with the sender address not being used as the return-path/bounce address when using system.net.mail to send email with a different address for the return-path/sender and the from address and using the SpecifiedPickupDirectory delivery method? This issue is particularly important when you need to send mail from a "user" address, but want bounce backs to come to a different address so they can be processed.

Using the code below, I think you can reproduce the issue.

Imports System.Net.Mail
Partial Class emailtest
    Inherits System.Web.UI.Page

  Protected Sub test_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles test.Click

    ' Build Message
    Dim mail As New MailMessage
    mail.From = New MailAddress("from@domain.com")
    mail.Sender = New MailAddress("sender@domain.com")
    mail.Subject = "Test Subject"
    mail.Body = "Test Body"

    ' Drop in Pickup Directory
    Dim smtpPK As New SmtpClient
    smtpPK.DeliveryMethod = SmtpDeliveryMethod.Sp

Pass delivery method, email address to create SSRS subscription using VS2005



I have created SSRS reports and built a user UI to run these reports. Now when creating SSRS subscriptions in report Manager, is it even possible to programmatically pass the delivery method (email or file share), To email address, scheduled time and date, etc from my front-end UI to the Report Manager?

Any help will be greatly appreciated. Thanks

Email Help (System.Net.Mail)


Hi I have a annoying problem. 
I have created a page which takes users details for a quote.

I have then created the form to be emailed to both the user and myself. (Which works fine ATM)

However I would also like to be able to attach a file containing terms and conditions to the email.

I have tried doing this using 

EmailMsg.Attachments.Add(new Attachment("C:\\attachme.txt"));

But everytime that line of code is hit it fails and is caught by my try catch.

Take that line out and the email sends fine, put it in and it breaks the whole page.

Am I missing something really obvious?

System.Net.Mail.SmtpException: net_io_connectionclosed

I'm getting "System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed." but only occasionally.  I'm confused because:1) The SMTP server is the local machine so why would the connection ever fail? and2) The error only happens sometimesThere was a similar question posted here: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=418540&SiteID=1 but it seems they were having problems sending any mail to begin with.Here is the full stack trace:System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed.   at System.Net.Mail.SmtpReplyReaderFactory.ProcessRead(Byte[] buffer, Int32 offset, Int32 read, Boolean readLine)   at System.Net.Mail.SmtpReplyReaderFactory.ReadLines(SmtpReplyReader caller, Boolean oneLine)   at System.Net.Mail.SmtpReplyReaderFactory.ReadLine(SmtpReplyReader caller)   at System.Net.Mail.SmtpReplyReader.ReadLine()   at System.Net.Mail.CheckCommand.Send(SmtpConnection conn, String& response)   at System.Net.Mail.DataStopCommand.Send(SmtpConnection conn)   at System.Net.Mail.SmtpConnection.OnClose(Object sender, EventArgs args)   at System.Net.ClosableStream.Close()   at System.Net.Mail.MailWriter.Close()   at System.Net.Mail.SmtpClient.Send(MailMessage message)I'm unable to recreate this error since it onl

Hi Experts, We have an Asp.net web application, which is deployed in shared hosting environment. On shared hosting environment initial request to this web application is handled by Linux server and then based on the requested page the Linux server is redirecting request to web server on windows OS.

Best Way to Store Users Mail Address

I have some webforms and the main page grabs the users email address when they login and a UserID.  It's not uncommon for the user to keep the web page open all day.  Is it good practice to store the email address and ID as a session variable and up the timeout to say 10 hours?  Or is there a better way?  My concern is A) Session variables timing out before the user login timesout B) Doing this incorrectly. Thanks!

How do I access the custom headers created with System.Net.Mail?

I've created some custom headers for my emails.  I've used a breakpoint to see that they are being added to the collection correctly.  I don't understand how to access these from the email that's generated though.  I'm currently dropping the emails into a pickup directory on my local machine and viewing them with Windows Mail.  I have "view all" headers checked in Windows mail but still don't see them when I open my emails in the pick up directory.Can someone please tell me how to access the headers that I added?  Below is an example of how I did it.  I'm hoping to add things like name, address, phone... etc, and then have them visible in the email.   Is this even the correct use of custom headers? message.Headers.Add("X-Name", txtName.Text);  

Problem with overriding OnPaint method of System.Windows.Forms.Textbox

Hi,   I want to change the border colour of the Textbox. However, when I override the OnPaint method, some strange behaviour occurs.   The new border is drawn, as is the textbox background. However, the text itself appears in bold and only while I actually type something in, afterwards it disappears. I have provided a sample of my code here:         protected override void OnPaint(PaintEventArgs e)         {             base.OnPaint(e);             Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);             ControlPaint.DrawBorder(e.Graphics, rect, _BorderColour, ButtonBorderStyle.Solid);         }   I have also set the style of the control to Userpaint, so that the paint method is actually used. Does anybody know how to solve this issue?

Weird Exception: Method not found: 'Double System.Windows.Controls.ScrollViewer.get_ContentHorizon

Hi guys I have an XBAP application that uses a Xamdatagrid from Infragistics. I have some filtering on this grid, that rebinds after a filter. The problem is, when a user has scrolled to a certain point and then filters, the rebinding causes the grid to scroll to the beginning position of the grid. Now how I solve this is by getting an instance of the ScrollViewer, I get the ScrollViewer.ContentHorizontalOffset and then I do a ScrollViewer.ScrollToHorizontalOffset after it filters.   Now here comes the problem. For 99% of the users of this xbap app, this will work absolutely fine. Most, if not all of the users run exactly the same machines, XP 64 bit with 8GB RAM. The other 1% get the error: Method not found: 'Double System.Windows.Controls.ScrollViewer.get_ContentHorizontalOffset()'. I cannot reproduce this error on my own box, our dev server or our production server, it is a phantom exception that only pops up on a certain condition. I have even wrapped the "offending" code in a try catch and it still doesn't solve it. If I set the DispatcherUnhandledExceptionArgs Handled to true, it works, but it doesn't feel right. How is this possible? If the method doesn't exist, how can it compile? Why does that method exist for 99% of the other users running the exact same machines? I have googled my fingers raw without any valid results and this issue is frustrat
