问题描述

嗨;

这是我的班级：

Hi;
i am writing a simple class representing an email server, and a Test Method to test the provided Mail Server informations, however, when i try to connect with smtp.live.com:25 with ssl enabled i got an exception "unexpected packet format" , i''m using MailSystem.Net API and testing with SMTPClient Class.
Any help is welcome , thank you.

Here is my Class :

Public Class MailServer

    'Ctors :
    Public Sub New()
        Me.Host = "smtp.host.ext"
        Me.Port = 25
        Me.Secured = False
    End Sub

    Public Sub New(ByVal host As String, ByVal port As Integer, ByVal secured As Boolean)
        Me.Host = host
        Me.Port = port
        Me.Secured = secured
    End Sub

    'Properties :
    Private _Host As String
    Public Property Host As String
        Get
            Return _Host
        End Get
        Set(value As String)
            _Host = value
        End Set
    End Property

    Private _Port As Integer
    Public Property Port As Integer
        Get
            Return _Port
        End Get
        Set(value As Integer)
            If value >= Net.IPEndPoint.MinPort OrElse value <= Net.IPEndPoint.MaxPort Then
                _Port = value
            End If
        End Set
    End Property

    Private _Secured As Boolean
    Public Property Secured As Boolean
        Get
            Return _Secured
        End Get
        Set(value As Boolean)
            _Secured = value
        End Set
    End Property

End class

这是测试方法：

And Here is the Test method :

Public Sub Test(ByVal ms As MailServer)
        Try
            If ms.Secured = True Then
                _TestSmtp.ConnectSsl(ms.Host, ms.Port)
            Else
                _TestSmtp.Connect(ms.Host, ms.Port)
            End If
        Catch ex As Exception
            'Message Box Here...
        End Try
    End Sub

推荐答案

端口25通常不与SSL一起使用。检查live.com的规格你必须使用哪个端口（587,997或类似的东西）。

Port 25 is normally not used with SSL. Check the specs from live.com which port you have to use (587, 997, or something like that).
