5.7.1 从 vb.net 应用程序访问时中继访问被拒绝

我正在用 vb.net 开发一个程序，它需要直接连接到我的邮件服务器 (postfix) 来发送电子邮件，这些电子邮件将直接发送到电子邮件到短信传输。我的邮件服务器运行正常，我没有遇到任何功能问题（它在 squirrelmail 上发送和接收都没有问题）。我还尝试使用http://www.nanogenesis.fr/并且报告了相同的错误，我认为这是我的 postfix 设置的问题。我的应用程序目前正在运行代码（并且还可以轻松运行身份验证）：

        'create the mail message
    Dim mail As New MailMessage()

    'set the addresses
    mail.From = New MailAddress("[email protected]")
    mail.[To].Add("[email protected]")

    'set the content
    mail.Subject = "Page"
    mail.Body = "this email is to test the paging system"

    'set the server
    Dim smtp As New SmtpClient("fasttrackdispatch.com")
    Dim errmsg As String
    'send the message
    Try
        smtp.Send(mail)
        Console.Write("Your Email has been sent sucessfully - Thank You")

    Catch exc As Exception
        errmsg = "Send failure: " & exc.ToString()
    End Try

在我的软件方面这似乎可以正常工作，但是电子邮件没有发送，

mail.log 文件指出

任何帮助表示感谢

我认为发生的事情是 postfix 不知道它应该允许您的 IP 地址 (199.1.16.46) 进行中继。这可能不是最好的解决方案，但您可以将 etc/postfix/main.cf 中的 mynetworks 指令更改为类似以下内容：

mynetworks = 127.0.0.0/8, 199.1.16.46/32

然后重新启动 postfix 并查看是否能使其运行得更好。
