IMAP should not disconnect clients on bad command immediatelly
--------------------------------------------------------------
Key: IMAP-249
URL: https://issues.apache.org/jira/browse/IMAP-249
Project: JAMES Imap
Issue Type: Bug
Components: Parser
Affects Versions: 0.2-M1
Reporter: Wojtek Strzalka
Fix For: 0.2
When IMAP processor can not parse command immediately disconnects a client .
Unfortunately from time to time outlook sends bad commands to the server.
One of the examples is Outlook 2007 - when copying a message (drag & drop
message with Ctrl) it sends an empty request to the server ( \r \n ).
There are 2 options I can think about:
a) handling only the case would require consuming '\r' '\n' characters before
processing a tag
b) general change of error handling - here is what Courier-IMAP is doing:
instead of sending bye & disconnecting, we could send NO, to avoid DoS 10
consequent errors are allowed, then say bye
