截取片段原文:
APOP name digest
Arguments:
a string identifying a mailbox and a MD5 digest string
(both required) Restrictions:
may only be given in the AUTHORIZATION state after the POP3
greeting or after an unsuccessful USER or PASS command
Examples:
S: +OK POP3 server ready <[email protected]>
C: APOP mrose c4c9334bac560ecc979e58001b3e22fb
S: +OK maildrop has 1 message (369 octets) In this example, the shared secret is the string `tan-
staaf'. Hence, the MD5 algorithm is applied to the string <[email protected]>tanstaaf which produces a digest value of c4c9334bac560ecc979e58001b3e22fb
我是发到pop3.zj.com的。
收到POP3 greeting后直接APOP md5string就返回-ERR bad login (-17);
“or after an unsuccessful USER or PASS command”
我也试着先发user和错误的pass,返回失败后再发apop.还是失败,不过返回稍有改变:incorrect state (-40)Restrictions里面不是已经说的很清楚了吗?md5("<[email protected]>我的密码") == "dbefa29ed14c15a9adbeddda215276fb"
