Hi, I'm facing some issues regarding sending e-mails from your server. When I test this functionality locally, it works fine. Please see the following code: Imports System.Net.Mail Public Class Mail Public Sub New() End Sub Private ReadOnly Property HOST() As String Get Return "smtp.mail.yahoo.com" End Get End Property Private ReadOnly Property PORT() As Integer Get Return "587" End Get End Property Private ReadOnly Property USER() As String Get Return "username" End Get End Property Private ReadOnly Property PASS() As String Get Return "password" End Get End Property Public Function sendMail(ByVal itemRegarding As String, ByVal data As String) As Boolean Dim smtp As New System.Net.Mail.SmtpClient(HOST, PORT) Dim m As New MailMessage("[email protected]", "[email protected]") smtp.EnableSsl = False smtp.Credentials = New System.Net.NetworkCredential(USER, PASS) m.Subject = itemRegarding m.Body = "Following information has been received: " & vbCrLf & data Try smtp.Send(m) Catch Return False End Try smtp = Nothing Return True End Function Thanks and kind regards, Faisal
