imap - Limilabs IMAP 异常

Question

我正在尝试使用 Limilabs imap 库连接到电子邮件；

  tcpc = new System.Net.Sockets.TcpClient("imap.gmail.com", 993);

工作正常 ;而 limilabs imap 没有

using (Imap imap = new Imap())
{
    imap.Connect("imap.gmail.com", 993);

给出异常(exception):

Answer 1

Limilabs imap.Connect 有一个重载来指定是否使用 SSL。它不会从您指定的端口推断它。您还可以使用 imap.ConnectSSL 方法。
