Andrzej Rusin created IMAP-374:
----------------------------------
Summary: Client command line length limit is problematic
Key: IMAP-374
URL: https://issues.apache.org/jira/browse/IMAP-374
Project: James Imap
Issue Type: Bug
Components: Protocol
Reporter: Andrzej Rusin
Assignee: Eric Charles
I believe (based on some observations) that:
A) maximum client command line length in James IMAP is 8192 as defined in
org.apache.james.protocols.netty.AbstractChannelPipelineFactory.MAX_LINE_LENGTH.
B) I do not think that IMAP RFC limits the line length, at least I did not find
any reference of that.
C) James IMAP does not seem to reply with BAD when it sees a too long line.
D) Some clients send quite long lines (I just saw one about 23000 characters
and sky is the limit) and they probably expect some answer, hanging
indefinitely.
So:
1. If B is true, then we should not practically really limit in A; or rather
the limit should be really high. And looks like 640K is not enough for everyone
anymore ;)
2. Probably C should be fixed.
