I wanna send an Email from my Webservice, written in vb.net, but I get an Timeout.
What is wrong?
Dim toaddress As MailAddress = New MailAddress("xxx")
Dim fromaddress As MailAddress = New MailAddress("yyy")
' The structure for MailMessage(from, to)
Dim message As MailMessage = New MailMessage(fromaddress, toaddress)
message.Subject = "I have sent you a message from a program!"
message.Body = "Hello World!"
Dim messanger As SmtpClient = New SmtpClient("smtpxxx", 995)
messanger.Credentials = New NetworkCredential("user", "password")
messanger.EnableSsl = True
messanger.Send(message)
You are doing many things wrong and some of the information you have given are not clear enough. host name and port names have to give properly. it chooses which mail service you are using, from your code it is not correctly provided, so i will give a snippet that uses gmail to send mail. please go through this and make changes as per your SmtpHost.
Try
Dim Smtp_Server As New SmtpClient
Dim e_mail As New MailMessage()
Smtp_Server.UseDefaultCredentials = False
Smtp_Server.Credentials = New Net.NetworkCredential("email", "password")
Smtp_Server.Port = 587
Smtp_Server.EnableSsl = True
Smtp_Server.Host = "smtp.gmail.com"
e_mail = New MailMessage()
e_mail.From = New MailAddress(txtemail.Text)
e_mail.To.Add(txtemail.Text)
e_mail.Subject = "Email Sending"
e_mail.IsBodyHtml = False
e_mail.Body = txtMessage.Text
Smtp_Server.Send(e_mail)
MsgBox("Mail Sent")
Catch error_t As Exception
MsgBox(error_t.ToString)
End Try
This link help you to find the smtp.Server and Port numbers, you can use this thread for check the limitations of smtp.servers

i got error:
MAIL Error Message:Mailbox unavailable. The server response was:

The mail has been rejected by the server, there is nothing you can do to resolve this. You could in theory attempt to modify the content so that is does not appear as spammy, but this is likely to be a long and tedious process.
I've used this code to sending emails. When I test this code in LOCALHOST, it works correctly, but in host, I get this error:

I am trying to make a simple e-mail sending program but it has confused me when it said object reference not set to an instance of an object
Try
Dim mail As MailMessage
Dim client As SmtpClient
Dim SmtpServer As New SmtpClient()
Dim fromAddress As String
Dim toAddress1 As String
Dim toAddress2 As String
Dim toAddress3 As String
Dim subject As String
Dim message As String
SmtpServer.Credentials = New Net.NetworkCredential("*********#gmail.com", "**********")
client.UseDefaultCredentials = False
fromAddress = FromEmail.Text
If ToEmail1.Visible = True Then
toAddress1 = ToEmail1.Text
ElseIf ToEmail1.Visible = True And ToEmail2.Visible = True Then
toAddress1 = ToEmail1.Text
toAddress2 = ToEmail2.Text
ElseIf ToEmail1.Visible = True And ToEmail2.Visible = True And ToEmail3.Visible = True Then
toAddress1 = ToEmail1.Text
toAddress2 = ToEmail2.Text
toAddress3 = ToEmail3.Text
End If
subject = "Subject"
Message = "Message"
mail = New MailMessage(fromAddress, toAddress1, subject, Message)
client = New SmtpClient("Smtp.live.com")
client.Port = 587
Dim SMTPUserInfo As New System.Net.NetworkCredential("user#hotmail.com", "password")
client.Credentials = SMTPUserInfo
client.Send(mail)
MsgBox("sent")
Catch ex As Exception
MsgBox(ex.Message.ToString())
End Try
you're declaring two smtpclients
Dim client As SmtpClient
Dim SmtpServer As New SmtpClient()
you instantiated SmtpServer, but not client. Then you do
client.UseDefaultCredentials = False
I guess this is where the exception is raised.
the code looks like having some lines to send some mail through SmtpServer from a google account and other lines to send some mail through client from a hotmail account. Besides, SmtpServer is using some server defined in config.sys.
