主题：多个收件人中只要有一个人邮件地址不对就发不出去

汗，不应影响其它的发送啊。做个例子上来

Dim m As New MailSender
m.Host = "smtp.qq.com"
m.Account = "455189993@qq.com"
m.Password = "helen6849338."
m.From = "455189993@qq.com"
m.AddReceiver("medadfasdfili@Sin43434a.co3434m.cn")
m.AddReceiver("2450314695@qq.com")
m.Title = "李总明天来北京"
m.Content = "航班号是gz1234,上午11点到达,请注意接机"
m.Send

要检测错误，就这样发

Dim client As New System.Net.Mail.SmtpClient()
client.Host = "smtp.qq.com"
client.Credentials = New System.Net.NetworkCredential("455189993@qq.com", "helen6849338.")
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network
Dim message As New System.Net.Mail.MailMessage()

message.From = new System.Net.Mail.MailAddress("455189993@qq.com","别名")

message.To.Add(new System.Net.Mail.MailAddress("2450314695@qq.com","人名"))
message.To.Add("2450314695@qq.com")
message.Subject = "邮件测试"
message.BodyEncoding = System.Text.Encoding.UTF8

'message.Bcc.Add("2450314695@qq.com") '密送

'message.cc.Add("2450314695@qq.com") '抄送

Dim content As String

content &= "这是文字" & vbcrlf
content &= "也是文字"

message.Body = content

Try
    client.Send(message)
    msgbox("发送成功")
Catch ex As Exception
    msgbox("发送失败:" & ex.message)
End Try
