SMTP.Send() Returns After (or During) An Email Sending Session?

May 9, 2011

This vb.net code seems to work ONLY if run... and I keep the program open for an additional 5-10 secs AFTER I see the "email sent" message. If I instead wait 0-1 secs, and then close the prg, the email goes nowhere.Does SMTP.Send() return AFTER the email is completely sent... or just when the email BEGINS to go out? (Sometimes the email body and/or file attachment might be 10k long, and take a while.)

Dim myMailMessage As New Net.Mail.MailMessage()
myMailMessage.From = New Net.Mail.MailAddress(fromEmail)
myMailMessage.To.Add(toEmail)

.net - Different Increase In Email Size Using SMTP Class To Send An Email As Opposed To Outlook?

Jan 6, 2010

I am sending an email with an attachment using the following Code

Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo)
Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf")
With msg
.Attachments.Add(att)

[code]....

The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.

Email & SMTP - Program To Send Very Simple Text Email Messages

Feb 17, 2009

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)

IDE :: Sending Mail Via Smtp?

Feb 17, 2009

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.

Sending E-mail Without Using Smtp?

Jun 19, 2009

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.

Sending Email - Operation Timed Out / Not Sending Error

May 27, 2012

I am trying to Send an Email with an attachment (using Gmail) but I keep getting errors like "Operation Timed out" or Failure Sending Email". It was working earlier today but I found out that i needed to add Using statement because the email was having a file open that had to be deleted after it was sent but afterwards it doesn't work.

Here's what I have (Portion of it):
Private Sub SendMailOneAttachment(ByVal un As String, ByVal pass As String, Optional ByVal smtp As String = "smtp.gmail.com")
Using oAttach As Net.Mail.Attachment = New Net.Mail.Attachment((Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "\" & My.Computer.Name & "_" & fName & " .zip"))
Dim client As SmtpClient = New SmtpClient(smtp)
[Code] .....

The ports are correct I believe, no firewall up on my PC...

Line Break Sending SMS Through SMTP Ftrom .NET?

Jun 4, 2011

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).

VS 2008 : SMTP Server - Split The Sending And Receiving?

Oct 22, 2009

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)
