mailkit Sendmail的疑惑

我在云（asp.net）的服务器，我安装mailkit提供我的客户从我的应用程序发送电子邮件与他们的电子邮件拥有账户。mailkit Sendmail的疑惑

我的一个问题是，他可以发送3封电子邮件，并通过服务器那么接下来的电子邮件被拒绝的电子邮件：

“消息：连接尝试失败，因为连接的方没有未正确响应在一段时间之后，或已建立的连接失败，因为连接的主机未能响应213.190.193.29:25"

另一个问题是，他们发送给他的邮件，他临危一个‘SPAM’

可以帮我吗？

我今天不在办公室工作。我明天就把代码放进去！我aplication发送的，如Outlook，以相同的电子邮件电子邮件测试，测试连接..这是奇怪的同一个地址假定垃圾.. –

SMTP服务器通常有个限度为的次数，你可以连接到它在短期内时间。这很可能是问题所在。 – jstedfast
