i want the program to ping the server before sending the mail; if server is available then send mail if not then message box with warning appears notifying user to check VPN connection and sending of mail is canceled.
I 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.
View 3 RepliesI 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.

I'm trying to write my own SMTP server at the moment so that people can use it in their applications to send and receive emails.I am having a few problems at the moment with the TcpListener side of things though. Basically I do not want to start the TcpListener in the constructor of my class because people could be using this SMTP Server class just to send emails and might not care about receiving them. In fact the majority of people that use it will probably use it for that reason, to send and not to receive.
So I am now considering breaking this into 2 totally separate projects that have no dependencies on each other, but could easily be used in the same application if required. The reason I designed this with both 'features' in the same project in the first place was because that is how an SMTP server works - it can receive incoming SMTP requests and it can send SMTP server requests to other servers (and in some cases, receiving an SMTP request would cause it to send an SMTP command to another server)
I am looking to make a SMTP (Port 25) listener to listen in and accept incoming mail, look at the message source, make changes if needed, and retransmit the message out another port. This iwll make it act like a sort-of intermediary service.how one would write a port listener in VB.net, that could listen in on the port, and display the message in a text box (the whole source, headers and all, since that's what the mail comes in as anyway).

View 2 RepliesI have a very simple .net application for testing SMTP on .net. But i am receiving this weird error.
[Code]...
I'm using the TcpClient and TcpListener classes to read/write to the network when a request comes in on port 25. All I'm trying to do at the moment is make it so that my server program can receive SMTP messages from other SMTP servers. I've tested in Telnet - if I connect to my own IP on port 25 and type EHLO, MAIL FROM, RCPT TO, DATA etc then all works as it should and the details I entered are logged by the program (it doesnt do anything about delivering these details/email yet).all looks good... but then when I try and just send an email to my domain from my work account I can see that a connection is made to my program and the string "EHLO workdomain.com " is received by my program - my program responds to the remote SMTP server with "250-mydomain.com Hello" and then a CrLF and then "250-OK". After that point however, my app does not receive anything further at all from the server at work. I'm guessing I am doing something wrong with the data I'm returning when it sends EHLO but can anyone point me in the correct direction?
I was using telnet to test with, it seems that I have made it work only with telnet.In telnet each time I type a key the data is passed to the server, however with a real SMTP server it just sends each entire command in one go. So after altering my server a little I can now get it to respond with the 250-OK which I thought it already was doing.. but it still doesnt work. The remote server just sends EHLO and then thats it nothing more.Something interesting, at the moment I am ending all of my responses to the remote server with VbLf - if I change this to VbCrLf (which is what I believe it is meant to be according to the SMTP standard) then I get an infinite amount of empty strings sent to my program (or perhaps some other character that just shows as an empty string in intellisense when stepping through the code). Changing it back to just vbLf or ControlChars.Lf makes it go back to just sending EHLO and then nothing else..

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).
