当我在VWD 2010中作为本地主机进行“调试”时，该程序可以正常工作。 当我将其插入到我的web服务器我的try ... catch得到这个错误：System.Net.Mail作为本地主机工作，但是当我将它添加到我的Web服务器时，它不是
Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
这里是我的代码：
Imports System.Net.Mail
Dim msg As New System.Net.Mail.MailMessage
Dim fromAdd As MailAddress = New MailAddress("[email protected]")
msg.[To].Add("[email protected]")
msg.Subject = "Email Works!!!!!!!!"
msg.From = fromAdd
msg.IsBodyHtml = True
msg.Priority = System.Net.Mail.MailPriority.Normal
msg.BodyEncoding = Encoding.Default
msg.Body = "<h1>Body!!!!!!</h1>"
Dim host = Request.Url.Host
Dim smtpClient As New SmtpClient("smtp.email.com", "587")
smtpClient.EnableSsl = True
smtpClient.UseDefaultCredentials = False
smtpClient.Credentials = New System.Net.NetworkCredential("user", "pass")
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network
smtpClient.Send(Message)
好像你需要添加SMTP服务器IIS，请访问[http://forums.iis.net/p/1157046/1901343.aspx] –
你如何添加“SMTP服务器IIS“时，我的Web服务器不支持ISS。 – teledextri
使用端口25代替587. –
