Updated copyright notices to include the year 2018.

*-login: Remove unnecessary ssl-proxy.h include

*-login: Use io_add_istream() instead of io_add()

pop3-login: Cleanup - uncork output unconditionally before client_unref()

*-login: Add client_vfuncs.free() that is called when client refcount=0 This can be useful for plugins that want to run something after proxying ends. Use an empty default function so plugins can call super.free() without having to check if it's NULL.

*-login: Add client_vfuncs.input_next_cmd() This allows plugins to hook into all the pre-login commands. For example with imap-login most of the commands could already be hooked into, except for ID and AUTHENTICATE because their parameters reading is handled specially. This allows hooking into them as well. This is actually internal to all the login binaries, so it wouldn't have to be in login-common. However, login-common already has all the code to handle overriding functions nicely and this is a rather useful feature for all the protocols anyway, so it's easier this way and not too ugly.

pop3-login: Cleanup - move command handling to pop3_client_input_next_cmd()

*-login: Add client_vfuncs.send_raw_data() This allows login plugins to hook into seeing all the data that is sent to the imap/pop3 client.

*-login: Minor logging cleanup if client is disconnected before sending banner. Avoid unnecessarily adding "(no auth attempts in 0 secs)" when the reason string already makes it clear that the user didn't even have a chance to authenticate. This kind of disconnection currently happens only with some plugins.

pop3-login: Add FORWARD for XCLIENT This allows passing passdb variables. They are prefixed with forward_ when imported to extra fields.

pop3-login: Log proxy state as human-readable string.

*-login: Add client.proxy_get_state() for providing human-readable proxy state If not implemented, it defaults to the old method of returning proxy_state number.

pop3-login: Code cleanup - Make sure destroying client stops processing. It would currently do it in any case, but this makes it clearer.

Updated copyright notices to include the year 2017.

pop3-login: XCLIENT / XOIP no longer return -ERR for untrusted IP ranges. The command is simply ignored, similarly to imap-login ID.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

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.

imap/pop3-login: If auth failure reason already begins with [resp-code], don't prefix it with another one.

pop3-login: Added support for Zimbra proxy's XOIP command.

pop3-login: Disconnect client on 3rd invalid command (not 11th).

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

*-login: And actually make the previous changes work.

Updated copyright notices to include year 2014.

pop3: Use RFC 3206 [SYS/*] and [AUTH] response codes.

Oops :) Update copyrights to 2013 without breaking all .c files.

Updated copyright notices to include year 2013.

Renamed buffer_create_*data() to buffer_create_from_*data() for consistency. Especially i_stream_create_from_data() was a very similar function, which made it difficult to remember which one should have "from" and which one shouldn't.

Added a "session ID" string for imap/pop3 connections, available in %{session} variable. The session ID passes through Dovecot IMAP/POP3 proxying to backend server. The same session ID is can be reused after a long time (currently a bit under 9 years).

pop3-login: Fixed APOP authentication, broken by recent changes.

imap/pop3/lmtp proxy: Implemented detection of proxy loops with TTL. If proxying tries to continue after 5 forward connections, it fails. The limit of 5 is hard coded currently.

pop3-login: Implemented XCLIENT command for forwarding client ip/port from proxy.

pop3-login: Implemented XCLIENT command for forwarding client ip/port from proxy.

login-common API made more extensible for different kinds of protocols. Patch by Stephan Bosch.
