c# - IMAP 响应重复

Question

有人可以解释 IMAP 服务器响应行为吗？ 当我发送单个命令时，响应符合预期:

C: A0001 FETCH 10 (BODY[HEADER.FIELDS (SUBJECT)])
S: * 10 FETCH (BODY[HEADER.FIELDS (SUBJECT)] {21}
   Subject: FW: test

   )
   A0001 OK FETCH completed.

但是如果我一个一个地发送几个命令，响应行为是不清楚的:

C: A0001 FETCH 10 (BODY[HEADER])
S: * 10 FETCH (BODY[HEADER] {1632}
   ...
   A0001 OK FETCH completed.
C: A0002 FETCH 10 (BODY[HEADER.FIELDS (SUBJECT)])
S: * 10 FETCH (BODY[HEADER] {1632}
   ...
   A0001 OK FETCH completed.
C: A0003 FETCH 10 BODY[TEXT]
S: * 10 FETCH (BODY[HEADER.FIELDS (SUBJECT)] {21}
   Subject: FW: test

   )
   A0002 OK FETCH completed.

为什么重复响应？以及如何解决？ Code

问题是写入 ssl 流发生在 ssl 流的读取循环中。
