Using SmtpClient Through A Proxy?
Nov 29, 2011I've got a vb program that sends an email using SmtpClient. I can't seem to get the message to pass the Proxy server (ccproxy). When sending thru outlook, I set the SMTP server to the Proxy server address, and in the username field I add a #and the SMTP server name following the username. I have tried several differt things here, but to no avail. Here is a sample of how I am trying to send this:
emailuserid = "me@mysmtp.com#mail.mysmtp.com"
emailpassword = "mypassword"
smtpserver = "192.168.0.1"

Capture SMTP Transcript When Using SmtpClient In NET?

View 5 RepliesUse SMTPClient To Send An Email Message?
Aug 3, 2010This is my first time trying to create a windows application that can be used to send an email message. It's a new requirement that we have to satisfy. Our customer information is saved in a database and we needed to send them some advertisement messages to some or all of them.
I created a windows application but unfortunately I couldn't send a single email message.
I tried to modify my code several times with no luck; each time I'm getting a different exception message. I tried to search the wen for more information regarding this issue but I end up with the same result.
I don't know if I must have an smtp server to relay the messages and be able to send them. If this is the case how I can do that? Is it possible to accomplish this with something else.
Dim Message As MailMessage = New MailMessage()
Dim Smtp As New SmtpClient()
Dim SmtpUser As New System.Net.NetworkCredential()

VS 2005 SMTPClient Email Signature?
Feb 2, 2012I am using the SMTPClient in my VB.Net application to send emails. It appears it is getting an email signature from somewhere. Where does it get this signature? It looks like it is using an Outlook signature but our company no longer uses Outlook so the signature is wrong. Is there a way to remove the signature before sending the email?
View 1 RepliesVS 2008 Close An SMTPClient Session?
Sep 16, 2009I 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

View 1 RepliesSet The Max Amount Of Simultaneous Connections From The Smtpclient To The Mailserver?
Apr 7, 2009I've this small application I've built which loops thru our database and generates 30000 mails and sends them using System.Net.SmtpClient, but it's not working very well. At times it won't send for a couple of minutes, all in all it takes about 48 hours for all the mails to be sent. Our mail provider says it's because the mail server can only handle 10 connections simultaneuosly and that would be the reason why it halts. I've looked over the SmtpClient class but can't find any property to set max amount of connections. Does this problem sound familiar? Could that be the reason? If so, is it possible to set the max amount of simultaneous connections from the smtpclient to the mailserver?
View 4 RepliesSmtp - Check If Mail Was Successfully Sent With SMTPClient
Jul 13, 2011I'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).
Using Smtpclient To Send Email Outside My Domain Is Not Working?
Mar 16, 2012I am trying to send mail using SmtpClient() within my Winforms VB.Net program .Here is the code:
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
Dim _Attachment As String[code]......
For Host Name I using mail dot metaprosystems dot com, the user name and password are the user name and password I use to log into my mail server. This work when the To address is within my domain. For example bob at-sign metaprosystems.com. It does not work when I send to an email outside my domain. I get this exception in my catch block: "Mailbox name not allowed. The server response was: sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)"
Whether I include an attachment or not doesn't matter.I believe the problem is with my web hosting company, but so far they haven't come up with a solution. I need so advice as to what to tell them to do to fix this. Alternatively,
VS 2008 SmtpClient And Outlook Junk Mail
Nov 5, 2009I 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.

File Appears To Be Held Open After Being Sent As Attachment By SmtpClient
Feb 8, 2012I have a number of files that are generated in a function defined as:[code]These files are immediately printed and the files are automatically saved to a directory; the files themselves are not for use by the actual software users. I timestamp the files to keep them uniquely identified for auditing purposes.I've now received a requirement to email some of these files externally to the company, and someone has complained that the current filenames are not user-friendly.So, I tried copying the generated file to a temp directory, with a friendlier name, emailing the friendlier file, then deleting it, leaving my audit trail intact, like so: [code]This throws a System.IO.IOException on the line System. IO.File. Delete (friendly FilePath) because the file is still in use, after it has been emailed.I've taken out the email code, which makes the copying and deleting work fine, so it's apparently attaching the file to the email which causes the problem.I've also tried breakpointing before the delete line, waiting five minutes, confirming the email has been sent, then advancing the code, but the same exception is still thrown.
View 3 RepliesError BC30456: 'Dispose' Is Not A Member Of 'System.Net.Mail.SmtpClient'

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?

actually my app will monitor the gmail account for mails over a period of time, so if I don't save the password the I'll have to ask the user to enter the password every time the program starts.
