Communications :: How To Send Simple SMTP Mail
May 27, 2009
I'm using the following code to send simple SMTP mail. the code sends successfully on the development PC however, as soon as i move this to another environment (another PC) the message delivery fails..
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.
Imports System.Net
Imports System.Net.Mail
Code:
Public Sub SendEmail(ByVal Email_To As String, _
ByVal Email_CC As String, _
ByVal Email_From As String, _
ByVal Subject As String, _

I'm running VB.Net 2010. What is the best way to send e-mail via SMTP in this version? Is it still System.NetMail.SmtpClient or is there something built in/more intuitive, or...?

Well i got a page that sends emails and everything runs fine in the developer web server but when i publish to a IIS Server i get a FormatException when i try to send the mail.... ex.Message = "the specified string is not in the form required for an e-mail address."
the email is in this sample someone@gmail.com
Im using the "SmtpClient" and the "MailMessage" classes to send mails..
And the server runs windows server 2003
Edit: Im using same smtp settings on the Dev Webserver as im doing in IIS.

So ive looked everywhere but every example i find doesnt work on visual studio 05 and doesnt convert properly. I simply want to send info from one computer to another through direct connection. if anyone could point me in the right direction it would really be helpful. most stuff i find seems to be more complicated than what im looking for.
then just one other question. both computers will be going through a router. as long as i have the port im using forwarded on the hosts side, that shouldnt be a problem, right?

I'm trying to get my program to send very simple text email messages. I did do a search beforehand, and found that I was having the same issue as someone else, but the specific question I have was not answered --
I've learned that if you're trying to send mail, you need an SMTP server... I found this list here but every one of them I've tried yields the same "Failure sending mail" error.
Here's my
Dim mail As New MailMessage()
mail.From = New MailAddress("me@mycompany.com")
mail.To.Add("destination-email@whatever.com")
[CODE]...
Is the problem that I need to show "credentials" (i.e. user/pass)? If so, what would those credentials be? Can I use my yahoo email SMTP server with my login info to do it? And is this all I'd need to add to add the credentials?
smtp.Credentials = New NetworkCredential("MyUsername", "MyPassword")
(before the smtp.Send, of course)

I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

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'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).

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).
