imap: Add imap_fetch_failure setting This controls what happens when FETCH fails for some mails. The possible values are: disconnect-immediately: This is the original behavior. Whenever FETCH fails for a mail, the FETCH is aborted and client is disconnected. disconnect-after: The FETCH runs for all the requested mails, skipping any mails that returned failures, but at the end the client is still disconnected. no-after: The FETCH runs for all the requested mails, skipping any mails that returned failures. At the end tagged NO reply is returned. If the client attempts to FETCH the same failed mail more than once, the client is disconnected. This is to avoid clients from going into infinite loops trying to FETCH a broken mail.

imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs. This at least partially replaces the "rawlog" post-login binary. For now the "rawlog" binary supports some parameters, which aren't configurable for rawlog_dir.

imap: Implemented support for the LITERAL- capability. This replaces the LITERAL+ capability when the imap_literal_minus setting is enabled.

Changed type of internet port values to in_port_t everywhere. Created special SET_IN_PORT setting type for internet port values. Created net_str2port() for parsing internet port values. Removed several atoi() invocations in the process.

Added imap-hibernate process for gathering IDLEing imap processes. imap_hibernate_timeout setting controls how quickly the connection is moved from imap process to imap-hibernate process. Some IMAP extensions like NOTIFY, SEARCH=CONTEXT and COMPRESS aren't supported yet. There's also a new X-STATE command, which can be used to export the current IMAP connection state to a string and later on imported to get back to the original state (a quick resync feature for IMAP clients). However, this command is disabled for now due to the current code being unoptimized for untrusted input.

imap: Added initial support for METADATA extension. For now this is enabled only when imap_metadata=yes setting is used. The setting will go away once the feature is complete. Also mail_attribute_dict must be set. TODO: - Metadata doesn't work for public namespaces. There should probably be a mail_attribute_public_dict setting for that. - There isn't any kind of quota or other limits - After ENABLE METADATA start sending untagged METADATA entries to clients - /shared/admin should probably return postmaster_address URL - Check if we handle ACLs correctly - RFC says that it SHOULD be possible to set METADATA entries to \NoSelect mailboxes. We probably will never allow this though.

imap-urlauth: Store urlauth keys to the new mailbox attributes.

Added support for IMAP URLAUTH and URLAUTH=BINARY extensions Extends imap service with URLAUTH and URLAUTH=BINARY support: - Adds new commands URLFETCH, GENURLAUTH and RESETKEY. Creates imap-urlauth service in src/imap-urlauth. Functionality common to both the imap and imap-urlauth services is located in src/lib-imap-urlauth. TODO: - use mailbox GUIDs instead of names - doveadm command to delete stale urlauth entries? - add delay when attempting to access nonexistent user - create urlauth-worker queue, similar to how indexer-worker works (could we share code?..)

imap: Added tb-lsub-flags to imap_client_workarounds. Patch by Bruno Tréguier.

Removed unused auth/mail_debug settings from structs.

imap: Removed netscape-eoh (Netscape 4.x) from imap client workarounds. This client should be long dead by now. Also the workaround causes Dovecot to violate IMAP RFC, so it's not really recommended anyway. --HG-- branch : HEAD

Added "size" setting type, which supports B/k/M/G/T suffixes. --HG-- branch : HEAD

imap: Added support for verbose_proctitle=yes --HG-- branch : HEAD

Changed all settings related structs to const and changed APIs to make it work. --HG-- branch : HEAD

Handle shutdown_clients globally for all services. Delay shutting down processes until it's convenient for them, but if they're not gone in 30 seconds forcibly stop. And if that doesn't help, master will start killing them in 60 seconds. --HG-- branch : HEAD

imap, pop3: Moved imap/pop3_client_workarounds setting parsing to config checking. --HG-- branch : HEAD

verbose_proctitle setting works again. --HG-- branch : HEAD

Added imap_idle_notify_interval setting. --HG-- branch : HEAD

imap and pop3 now use mail-storage-service API. --HG-- branch : HEAD

Added lib-master and mail-storage-service code that makes it easier to build new Dovecot binaries. Currently only the standalone applications (e.g. deliver) uses this. --HG-- branch : HEAD

Plugin setting backwards compatibility support and other fixes. --HG-- branch : HEAD

Fixed variable expansion in master <-> mail processes. --HG-- branch : HEAD

Initial commit for config rewrite. --HG-- branch : HEAD
