如何使用IMAP协议在服务器上发送大量电子邮件? [英] How to send a mass email on a server use IMAP protocol ?

问题描述

对不起，我的英文，

我创建了一个程序，用于向使用IMAP协议的邮件服务器发送大量电子邮件，我使用了smtp.gmail.com的相似代码，并且在发送时，我始终收到此错误:远程根据验证程序，证书无效.
这是我的代码:

Hi,

Sorry my english,

I create a program to use for sending a mass email for a mail server that use IMAP protocol, I use a similary code of the smtp.gmail.com and when I send,I received all the time this error : The remote certificate is invalid according to the validation procedure.
This is my code:

Dim SmtpServer As New SmtpClient()
SmtpServer.Credentials = New Net.NetworkCredential("[e-mail]", "xxxx")
SmtpServer.Host = "smtp.abc.com"
SmtpServer.Port = 587
SmtpServer.EnableSsl = True

EMail.From = New System.Net.Mail.MailAddress("[e-mail]")

SmtpServer.Send(EMail)

您是否有针对此错误消息的解决方案?或解决此问题需要做什么?

谢谢
