Significant Bugs
In Versions up to 1.5.19, duplicate delivery suppression displays misleading errors in the
imapd.logthat might cause you to believe a message wasn’t delivered at all, when it actually was. This is fixed in 1.5.19 and later.There were a number of bugs that are fixed in Version 1.5.14. It is highly recommended that you upgrade if you’re running a version older than 1.5.14.
The IMAP RENAME command doesn’t behave hierarchically in Cyrus releases prior to 2.0, so it’s been temporarily advertised in the “capability” output as “X-NON-HIERARCHICAL-RENAME” in the interim before it’s fixed. Hierarchical rename is fixed in Cyrus 2.0.
deliver has a minor standard I/O problem in which text between a NUL and the end of line of a message will be lost. No fix is available as of the 1.5.19 release.
So much for building Cyrus. Let’s move on to the next chapter and the configuration of your Cyrus server.
