Known bugs in the Cyrus IMAP Server
imapd and core utilities
- Multiple APPENDs don't always correctly return the EXISTS response.
- Particularly large quotas can wrap around.
- 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 eventually.
deliver and sieve
- 8-bit set characters are coerced to 'X', but not before the notify_zephyr
code (if used) has had a chance to send them out.
- Deliver does not handle messages containing NUL properly due to
stdio problems (the characters between the NUL and the LF will be
lost.)
- Deliver doesn't gracefully handle CR CR sequences in messages.
Well, ok, it hangs.
- Once a Sieve script is in place, a "keep" action will obey plus
addressing, regardless of the ACLs on the mailbox.
authentication and authorization
- Using AFS groups with ptclient, users with negative rights as part of
groups may be granted access to mailboxes if ptclient has died. We plan
to have this fixed eventually.
- In some failures of the krbck program, the error messages printed out
bear no resemblance to what actually went wrong.
other utilities
- cyradm doesn't handle BYE quite properly (especially a BYE right after
connect).
- imtest doesn't properly default to using the LOGIN
command. also, it would be nice for the authorization name to default
to the authentication name, except when specifically overridden.
Things we want to do
- Implement the IMAP ID extension.
- Implement the IMAP VIEW extension.
- Implement the IMAP SORT and THREAD extensions.
- The vacation action in Sieve shouldn't respond to messages that
have an "Auto-Submitted" category anything but "No".
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 unified diffs (-u) if your diff program
supports them, or context diffs (-c) if it doesn't. Plain diffs are very
difficult to evaluate.
