我是Redmine用户和管理员。我想配置redmine以允许通过电子邮件创建问题和评论。我需要以这样的方式配置它，即它从标准输入（而不是来自imap pop3或电子邮件服务器）读取电子邮件。但是当我执行rake任务时，它显示如下所示的错误。可以任何人请帮忙解决它
bash-4.1# rake -f Rakefile redmine:email:receive_imap RAILS_ENV="production" host=smtprelay.intra.coriant.com port=25 --trace
** Invoke redmine:email:receive_imap (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute redmine:email:receive_imap
rake aborted!
