splitmail.rar

使用方法：

c:\mail.txt 放黑名單資料

執行程式 會排序 刪除重覆資料

如果是 gmail yahoo hinet seednet

常見免費信箱 封鎖 完整e-mail

奇怪的網域 則直接封鎖*@網域

 

Imports System.IO
Imports System.Text
Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        fileName = "c:\mail.txt"

            Exit Sub
        End If
        '第一次 去除 重複mail
        distmail(fileName)
        saveMAil(fileName)
