"myport",secure="yes");
imapService.open();

 

Note: If connection properties such as server, username, password, port, and secure are specified either during initialization or when open method is called, a connection is created implicitly. Therefore, you need not specify the properties for further actions. If sandbox security is turned on, the directory referred to by the property attachmentPath must be given the required permission. By default, the temp directory is used.
