我正在尝试使用MailKit库开发ImapClient。
如何永久从Gmail帐户中删除邮件,而不是将其移至“已删除邮件”文件夹?
答案 0 :(得分:11)
在大多数IMAP服务器上,执行此操作的方式是:
folder.AddFlags (uids, MessageFlags.Deleted, true);
这会在消息上设置\Deleted
标志。下一步将是:
folder.Expunge (uids);
这将清除文件夹中的消息。
假设这在GMail上不起作用,可能是因为只要在GMail IMAP服务器上的消息中添加\Deleted
标志,它就会将其移动到Trash文件夹(这是超出IMAP客户的控制权。)
这可能有用,但是......
// First, get the globally unique message id(s) for the message(s).
var summaries = folder.Fetch (uids, MessageSummaryItems.GMailMessageId);
// Next, mark them for deletion...
folder.AddFlags (uids, MessageFlags.Deleted, true);
// At this point, the messages have been moved to the Trash folder.
// So open the Trash folder...
folder = client.GetFolder (SpecialFolder.Trash);
folder.Open (FolderAccess.ReadWrite);
// Build a search query for the messages that we just deleted...
SearchQuery query = null;
foreach (var message in summaries) {
var id = SearchQuery.GMailMessageId (message.GMailMessageId);
query = query != null ? query.Or (id) : id;
}
// Search the Trash folder for these messages...
var matches = folder.Search (query);
// Not sure if you need to mark them for deletion again...
folder.AddFlags (matches, MessageFlags.Deleted, true);
// Now purge them from the Trash folder...
folder.Expunge (matches);
你已经完成了......
