Sending E-mails From Different SMTPClients.Host?
Feb 22, 2012
The main problem is that to send an E-mail from G-mail, you need to use smtp.gmail.com as the host, and the port number 587.
Dim SMTPServer As New SmtpClient
SMTPServer.Host = "smtp.gmail.com"
SMTPServer.Port = 587
SMTPServer.EnableSsl = True
However, for Hotmail, I would need a different Host and Port, smtp.live.com. Other E-mail clients would therefore require more different hosts. Is there a way, to address all of them without listing all possible E-mail host names and ports?
If not, what alternative is there to supporting all the E-mail hosts without throwing an error?

I am trying to send e-mails with VB.net and I have a template for the code but I don't understand a few lines.[code...]
As far as I understand, mail.From is the sender's name, and mail.to.add is the person I am sending to. What does smtpServer.Credentials do?
I deduce that SmtpServer.Credentials is the only one that requires a password so that will be the account the e-mail will be sent from. But then what is the point of mail.From? What happens if I put different e-mails in credentials and mail.From.

I have a software under contruction for a small firm. And it requires email functionality. That is, whenever the users in the main database reaches the payment date, an email will be send to that user as a reminder.Or, in certain period, the admin needs to send a notification mail to all the users in the main database.
So, how can I incorporate that facility in my main app ?My present idea is to create a separate app for send the mails. That is, when the admin compose the mail and selects a bunch of users (as recipients) from the database, all the message will be saved to another database (for mailing application) and will start the mailing app. This mailing app will check it's database for any pending emails to be sent, and if there exists any pending mails, it will start sending one by one. After sending each mail, it will remove that from the database.
What's your idea ? Does it sounds ok to you I don't want the user of my main app to know that there exist another program, running in background, sending emails.

I am using VB.net to send my mails through outlook. Where i am giving the resource path for the pictures inserted in to it.
But Email shows the inline pictures as attachments. what could be the reason?
The important thing is that this is not happening all the time. if we send 5 to 10 times we get the expected result for 2 or 3 times.
i explored some of the forums , got answers like 'changing the settings, security settings of the office outlook. that too is not succeeded.
I am giving you the code I am using in my project.
The code is given below

I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.

I'm new in web development and would like to add a feature to a project I'm working on. I'd like to send emails with this project, and also to have a kind of agenda. I'm already using outlook for the mails and the agenda. The thing I'd like is to have a kind of template. I've got it difficult to explain what I'm looking for, as far as I'm not a native english speaker.
So, let's have an example : I'd like to develop customer loyalty. So, I'd like to send mails to a few customers (maximum 10 mails sent per offer). In the view, I'll have to make a research on a keyword, which will return a list of customers. I'd like to have, next to each client, a hyperlink called "mail", wich would open Outlook, with the mail that's allmost fullfilled (with the name of the guy I'm mailing). Is it possible to do this like that?

In order for my program to share information between users, the best method I could come up with is using e-mails.I have a way of sending e-mails with the appropriate attachments, but would love a way to automatically retrieve these e-mail attachments directly from the program, without the user having to go to their e-mail account, find the correct project e-mail, download the attachment and then put it in the correct folder.I had hoped that VB.Net would have a built in procedure for doing this, but it seems there's not really anything there.

I am developing a vb.net desktop application that reads mails from the mailserver using pop and imap. The application is almost fnished .The problem is the some time when a command is send to retrieve a mail using GetMessage() functions the applications is going to a halt. So I tried to run the the code in debug mode and ran line by line.
What I noticed is in the while loop in GetMessage() function is
While Not tmpString.StartsWith(sPrefix)
tmpString = reader.ReadLine
msg = msg & tmpString & vbCrLf
End While
The reader reads line by line at certain point of time it got hangs. Some times it ill catch an exception and give an error. I am pasting the exception below:
"Received an unexpected EOF or 0 bytes from the transport stream".
But some times the applications will hang and go for a halt. This applications has to run 24/7. So if it hangs in the night or it will be problem. What I want is if the reader is not able to read from the stream after certain time period. The control has to be removed from the reader and the function has to return a message. I am new to this the network level applications and I am running shot of time.
Public Sub connect()
Dim objTCP As New TcpClient
Dim sslstream As Net.Security.SslStream
Dim reader As StreamReader = Nothing

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)

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