pop3 quit命令失败 [英] pop3 quit command fails

问题描述

大家好，
我在想什么可能导致QUIT(POP3)命令失败的情况?如果无法退出，会有什么副作用?例如，是否会导致尝试读取邮件的新连接出现问题?

Hey guys,
I was wondering what possible scenarios could cause a QUIT (POP3)command to fail? and if it failed to quit, what would be the side effects? for example, does it cause problems with new connection trying to read mails?

推荐答案

请参阅 ^ ].

失败的原因通常与-ERR响应一起发送.

如果服务器无法删除使用DELE命令标记为删除的邮件，则QUIT命令可能会失败.您必须假设没有或没有删除所有标记的消息.应该建立一个没有问题的新连接.

如果以前未建立连接，则QUIT命令也可能失败(先前的登录命令返回错误).

See RFC 1939[^].

The reason of the failure is usually send with the -ERR response.

The QUIT command may fail if the server can''t delete messages that has been marked for deletion with the DELE command. You must assume that no or not all marked messages has been deleted. A new connection should be established without problems.

The QUIT command may also fail if the connection has not been established before (a prior login command returned with an error).
