Known bugs in the Cyrus IMAP Server

• The RENAME command does not have the hierarchical behavior required by the IMAP4rev1 specification. The CAPABILITY command now returns X-NON-HIERARCHICAL-RENAME in its response in order to advertise this bug. We plan to have this fixed in the next release.
• Using AFS groups with ptclient, users with negative rights as part of groups may be granted access to mailboes if ptclient has died. We plan to have this fixed in the next release.
• We are aware that cyrus.seen files are occasionally corrupted, but we are not sure why this is happening. It seems to happen most with mailboxes with a large number of users. We hope to have this fixed in a future release.
• UID FETCH of a range of nonexistant UIDs causes the server to drop connection.
• imtest cheats and sends a non-synchronizing literal if you try to LOGIN (cleartext passwords).
• In some failures of the krbck program, the error messages printed out bear no resemblance to what actually went wrong.
• Deliver does not handle messages containing NUL properly due to stdio problems (the characters between the NUL and the LF will be lost.)

Please report bugs to cyrus-bugs@andrew.cmu.edu. Be sure to include (at least) system type, compiler used, and the options passed to configure, along with a detailed report. Additional information is welcome, and naturally, patches are deeply appreciated.

If you submit a patch, please send context diffs or unified diffs, not the default.
