There is a new version of the Dovecot IMAP and POP3 server released. It’s a bug fix release that where discoverd since the last release. I’ve updated all my test servers without any issue. Here is a list of issues fixed:

• Mailbox names with control characters can’t be created anymore. Existing mailboxes can still be accessed though.
• Allow namespace prefix to be opened as mailbox, if a mailbox already exists in the root dir.
• Maildir: dovecot-uidlist was being recreated every time a mailbox was accessed, even if nothing changed.
• listescape plugin was somewhat broken
• Compiling fixes for non-Linux/BSDs
• imap: tb-extra-mailbox-sep workaround was broken.
• ldap: Fixed hang when >128 requests were sent at once.
• fts_squat: Fixed crashing when searching virtual mailbox.
• imap: Fixed THREAD .. INTHREAD crashing.
