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.
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.
I Started to create an application in vb.net and the application mainly monitors the drives and when the drive's free space is below a certain percentage it sends an e-mail to recipient chosen..

[URL] it throughs and exception and states the following:

Observations: >> Locally I'm using a version of .Net (2.0.50727) (under application properties > references) >> The remote machines for which this is failing on has various version of .net 1, 2, 3 >> I'm using the VS2005 and publishing with the wizard >> Used a packet sniffer to monitor the network interface connected to the network and the no traffic is being generated by the source/sending PC.

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.

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).
how can i send an email in Visual basic? i have tried and i cannot get my code to configure with smtp.gmail.com... I need some code to do this. If it is not worth it, it is not fun - you say programmers are boring but i say they are worth it.

I am working on an email that someone will send from one of our main sites requesting an account password.I am using System.Net.Mail.MailMessage to create the email and then sending it using System.Net.Mail.SmtpClient.[code]
this is driving me absolutely crazy. I am trying to send an email through a web service written in C# through GoDaddy's servers (smtp.secureserver.net) but for some reason it's not working. Here's my code:
I wrote a VB.NET application to send notifications by SMS using an SMTP gateway [URL]..The message includes line breaks and display well under most providers but not all.For some providers, the message will display in one line with line breaks showing as "0D0A" which just won't work for me.
Is therea solution to this problem?Using an SMS agregator is out of the question for my solution.
Yes, I did that. Turned out to be carrier specific. Yet another problem i am having is specific to the phone model (one specific user receive the messages well on his old razor, changed to a new motorola phone with the same carrier and now receives an empty message).
