在Ruby Net :: IMAP中选择邮箱“发送邮件”或“所有邮件”

imap.select('INBOX')

工作正常,但

imap.select('Mail/sent-mail')

如Net :: IMAP文档中所示,给我“未知的邮箱”.

顺便说一句,这是用于gmail.

我也尝试在我的imap.search()中添加“in”,“anywhere”,但没有解析.

当前代码：

imap.select('INBOX')
now = Time.now.localtime - 1209600 #two weeks
since = now.day.to_s() + "-" + Date::MONTHNAMES[now.month] + "-" + now.year.to_s()
puts "since"
puts since
begin
  mail_ids = imap.search(["FROM","me","SINCE",since])
  mail_ids.each do |id|
    text = imap.fetch(id,'BODY[HEADER.FIELDS (SUBJECT)]').to_s.split("{").second.chop
    puts text
  end
end
