lib-lda: Added SMTP parameter fields to struct mail_deliver_context. This moves the original recipient field inside the SMTP parameters. This also affects both lda and lmtp. Changes are applied there accordingly.

lib-lda: Changed struct mail_deliver_context address fields to use the new struct smtp_address type.

lib-lda: Renamed struct mail_deliver_context fields for consistency with lib-smtp. New fields are added in subsequent commits.

lib-smtp: smtp-submit: Made submission_timeout a setting rather than a function parameter. This makes it configurable.

lib-storage: Renamed duplicate to mail_duplicate. This makes more sense given where this is now located.

lda/lmtp: Parse SMTP submit settings.

lib-lda: Fix deliver_log_format variables with Sieve With Sieve it was using src_mail for getting the values, which weren't correct especially if Sieve had modified the mail.

lib-lda: Redesign mail_deliver_context.var_expand_table cache

lib-lda: Remove unused mail_deliver_get_log_var_expand_table()

lib-lda: Added missing include file. This fixes building Pigeonhole in some systems.

lda, lmtp: Added delivery_time and session_time variables to deliver_log_format session_time is meaningful only with LMTP. The delivery_time is separate for each mail delivery. The results are in milliseconds now. If needed we could add a new %modifier that converts it into secs.millisecs.

lda/lmtp: Added a hardcoded LDA_SUBMISSION_TIMEOUT_SECS=30 timeout for SMTP client. Maybe we could have a new setting if needed later on, but we've been working pretty successfully without any timeout for a long time..

lda/lmtp: If mail delivery fails with tempfail, don't fallback to saving to INBOX.

Removed all the "enum foo;" declarations. They didn't seem to be very standard. Old gcc versions warn about them and C++ code doesn't like them.

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]

Marked functions parameters that are allowed to be NULL. Some APIs were also changed. The non-obvious APIs where NULL parameter was changed to "" are master_service_init() and auth_master_user_list_init(). These checks can currently be enabled only on a patched clang: http://llvm.org/bugs/show_bug.cgi?id=6786

lib-lda: Send DSN only for out-of-quota errors. Send MDN for Sieve rejects.

lda: If DSN is sent because user is out of quota, send 5.2.2 as Status.

Moved GUID code to liblib. Use guid_128_t type consistently everywhere.

lib-lda: Do INBOX GUID deduplication based on mailbox GUID, not username. This should be a bit more reliable.

lib-lda: Simplified mail_deliver_deduplicate_guid_if_needed() API.

lmtp: If delivering duplicate messages to same user's INBOX, use different GUIDs. This is to avoid POP3 clients getting confused with duplicate UIDLs, when using GUIDs as UIDLs.

lib-lda: mail_deliver_save() tries now to avoid re-parsing message header when logging the result.

lda: Added -r parameter to specify final recipient address. (As opposed to -a which specifies original recipient address.) This is going to be used by Sieve checks.

lib-lda: Added mail_deliver_hook_set()

lib-lda: mail_deliver_save_open() API changed to return also error code.

lib-lda: Added mail_deliver_save_open() for merging code with sieve. --HG-- branch : HEAD

lib-lda: Added mail_deliver_get_log_var_expand_table(). --HG-- branch : HEAD

lmtp: Add Received: header, with a session ID. Log the session ID also. --HG-- branch : HEAD

lib-lda: Fixed duplicate database to work with multiple users per process. --HG-- branch : HEAD

mail_deliver(): Support returning a destination mail. --HG-- branch : HEAD

Renamed deliver to dovecot-lda and moved most of its code to lib-lda. --HG-- branch : HEAD
