lmtp: proxy: Use source_ip proxy field if it is returned from passdb. Before, it was ignored. Now, it is used as the source IP for the outgoing LMTP client connection.

lmtp: proxy: Use per-connection SMTP client settings. This is needed for setting source IP in later change. The peer_trusted setting must me moved, since this setting is overriden by per-connection settings, rather than merged.

lmtp: proxy: Do not forward 421 reply (server shutdown) from backend. This closes the LMTP connection implicitly. Instead, translate it into a 451 4.4.0 response, just like all the other connection-related failures.

lmtp: Add recipient type to struct lmtp_recipient.

lmtp: Move common recipient handling code to separate file.

Updated copyright notices to include the year 2018.

lmtp: Ported to use lib-smtp/server. Implicitly fixes handling of multi-line replies from proxy backend. Implicitly adds support for mixing local and proxy recipients. Implicitly adds support for SMTP CHUNKING. RCPT failures are reported back to the client immediately, rather than waiting for the DATA command.

lmtp: proxy: Restructured proxy so that it has direct access to struct client. This avoids the hassle of initializing using struct lmtp_proxy_settings and uselessly reallocating stuff that is already persisted in struct client. Moved the proxy from alloconly pool to default pool in the process. The amount of allocated stuff will diminish further in subsequent commits.

lmtp: proxy: Renamed pool to auth_pool in lmtp_proxy_rcpt() for clarity.

lmtp: proxy: Made struct lmtp_proxy_rcpt_settings private.

lmtp: proxy: Merged lmtp_proxy_add_rcpt() into lmtp_proxy_rcpt().

lmtp: proxy: Made lmtp_proxy_mail_from() private.

lmtp: proxy: Made lmtp_proxy_init() private.

lmtp: Split off local delivery in a struct separate from the client. This mimics proxy delivery, making the implementation better structured.

lmtp: proxy: Changed return type of lmtp_proxy_rcpt() from bool to int.

lmtp: proxy: Renamed client_proxy_rcpt() to lmtp_proxy_rcpt().

lmtp: proxy: Renamed client_proxy_is_ourself() to lmtp_proxy_is_ourself().

lmtp: proxy: Renamed client_proxy_rcpt_parse_fields() to lmtp_proxy_rcpt_parse_fields().

lmtp: proxy: Added structural comments.

lmtp: proxy: Removed dns_client_socket_path from struct lmtp_proxy_settings. It is globally accessible.

lmtp: proxy: Moved lmtp_proxy_connection_finish().

lmtp: proxy: Moved lmtp_proxy_rcpt_cb().

lmtp: proxy: Moved lmtp_proxy_add_rcpt().

lmtp: proxy: Moved lmtp_proxy_data_cb().

lmtp: proxy: Moved lmtp_proxy_data_dummy_cb().

lmtp: Moved code relating to proxy from commands.c to lmtp-proxy.c.

lmtp: proxy: Fix connection settings comparison in lmtp_proxy_get_connection() when hostip field is set. The IP in the hostip field overrides the host setting, which broke the comparison.

lmtp: proxy: Fixed use of hostip field after changing the implementation to use lib-smtp/client broke it. Proxy was erroneously doing DNS queries while hostip field was returned from passdb.

lmtp: proxy: Fixed proxying reply from backend server. It contained an additional CRLF, which caused problems.

lmtp: proxy: Changed implemention to use lib-smtp/smtp-client.

lmtp proxy: Avoid DNS lookup for "host" if passdb also returns "hostip"

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro.

lmtp proxy: Include in log messages how long it took to deliver the mail. In multi-RCPT TO sessions it's a bit unreliable to split the single DATA reply's times to multiple lines, so instead each line just says "(2/3 at 123 ms)" meaning that the second mail was delivered at the time when 123 milliseconds had elapsed since the delivery was started.

lmtp: Added support for DSN ORCPT parameter. If the parameter is specified, it's used as the original recipient address in Sieve. The ORCPT parameter is also proxied to destination LMTP server if used (without checking if it supports it). We don't currently advertise DSN extension, so this feature won't be enabled automatically.

lib-lda, lmtp: Separate internal errors from remote errors. LMTP proxy shouldn't log remote errors with error level, because the proxy itself didn't have any failure. This is an API change, but I'm not aware of any plugins actually using the lmtp-client.h directly.

lmtp proxy: Make sure DATA stream size doesn't change unexpectedly.

lmtp: Create all proxy DATA streams before reading from them. I'm not sure if this actually fixes anything or not, but it's still safer to do it this way.

lmtp: Proxying now logs successful and failed deliveries after DATA.

lmtp: Removed some unnecessary code

proxying cleanup: Send TTL=1 (instead of TTL=0) as "no more proxying".

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