使用Delphi和Indy连接到Amazon Work Mail

根据亚马逊发布的说明:

Connect to your IMAP Client Application

You can connect any IMAP-compatible client software to Amazon WorkMail by providing the following information: 

Type of account IMAP 
Protocol IMAPS 
Port 993 
Secure connection Required;SSL 
Incoming username Email address associated with your Amazon WorkMail account 
Incoming password Your password 
Incoming server The endpoint matching the region where your mailbox is located: â¢ us-east-1 imap.mail.us-east-1.awsapps.com

我唯一编码的操作是 IMAPClient.Connect();

TIdIMAP4.GetResponse: string;

TIdImap4.UseTLS 属性自 utUseRequireTLS utUseImplicitTLS 。IMAP端口993期望客户端在连接套接字后立即发送SSL/TLS握手,然后服务器才能向客户端发送IMAP问候语(加密)。不做那种握手, utUseImplicitTLS

另一方面,您不应该设置当前正在设置的SSLIOHandler的大多数属性。您应该手动设置的唯一属性是 Name SSLOptions ,以及所需的事件处理程序。其余物业由Indy内部为您处理(主要由 Connect() ),所以你不需要和他们乱搞。
