Updated copyright notices to include the year 2018.

imapc: Add imapc_features=no-msn-updates This is a stricter version of fetch-msn-workarounds. The MSNs aren't trusted at all. This means any new untagged EXISTS and EXPUNGE replies are ignored, as well as untagged FETCH replies that don't include UID. A potential downside with this feature is that UID FETCH/STORE commands sent to expunged messages will likely fail without the IMAP client being notified of the EXPUNGEs. New mails are also not noticed, so this should be used only when it's known that the clients don't keep the connection open for long.

imapc: Add imapc_features=fetch-empty-is-expunged When FETCH returns an empty mail, the mail is assumed to be expunged.

imapc: Add imapc_features=send-id to send ID x-session-ext-id

imapc: Add imapc_features=fetch-bodystructure This allows using the remote IMAP server's BODY and BODYSTRUCTURE replies.

imapc: Change imapc_connection_retry_interval setting to be in milliseconds.

imapc: Change imapc_connection_retry_interval default to be 1 second. 10 secs at least is too high. Usually the connection problem is very intermittent and even an immediate reconnection would succeed.

imapc: Remove "_sec" suffix from imapc_connection_retry_interval_secs Its type is SET_TIME, so the value doesn't have to be in seconds.

lib-imap-client: Make retry count and interval configurable

imapc: Add imapc_features=delay-login The connection to imapc_host is delayed until it's actually needed to be performed.

Updated copyright notices to include the year 2017.

imapc: Added imapc_max_line_length to limit maximum memory usage. The default is still unlimited, but this should be set to something smaller for untrusted servers.

imapc: Added support for imapc_features=modseq If the remote server supports CONDSTORE or QRESYNC extensions we'll use the remote's MODSEQ and HIGHESTMODSEQ counts. There are some situations where the HIGHESTMODSEQ isn't updated exactly correctly on an open mailbox, so this feature shouldn't be fully relied on. It was primarily implemented for dsync+imapc support - both for preserving modseqs and also for HIGHESTMODSEQ lookups.

imapc: Added imapc_features=fetch-fix-broken-mails This allows ignoring a missing FETCH reply. It shouldn't be used normally, but if there's a mail that the IMAP server simply won't serve, this can be used to finish dsync successfully.

imapc: Added imapc_cmd_timeout setting to control the command wait timeouts.

imapc: Added imapc_features=fetch-msn-workarounds This can be used to work around broken servers that send invalid MSNs. This avoids errors like: imapc: Mailbox 'INBOX' state corrupted: FETCH UID mismatch (78976 != 82589)

imapc: Added support for PROXYAUTH command by setting imapc_features = proxyauth This can be useful when talking to Sun/Oracle IMAP server, which wants you to use LOGIN+PROXYAUTH to perform master user logins, instead of supporting the standard SASL PLAIN authentication.

imapc: Added imapc_features = no-examine

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.

imapc: Added imapc_features=zimbra-workarounds Zimbra (at least v5.0.18_GA_3011.RHEL4_64) can return different headers depending on whether the whole message body was fetched or only (partial) headers. This probably happens only for invalid characters that are translated into '?'. With this workaround enabled we don't use FETCH BODY.PEEK[], but we do FETCH (BODY.PEEK[HEADER] BODY.PEEK[TEXT]) and merge the results together. This way the results are always consistent and headers don't suddenly change.

imapc: Added throttling settings to imapc_features=throttle:a:b:c This change could be reverted once good settings are found.

imapc: Added imapc_features=search support for sending SEARCH commands. Currently requires the remote server to support ESEARCH (but this would be easy to avoid). This is only minimally tested for now, so bugs may exist (especially related to sub-queries).

imapc: Merged gmail-pop3 and gmail-labels-keyword features into a single gmail-migration feature There's really no other reason to use them except for migration.

imapc: Implemented imapc_features=gmail-pop3 that also migrates pop3_deleted_flag. This also caused gmail-pop3-uidl feature to be renamed to simply gmail-pop3, which includes both the features.

imapc: Added imapc_features=gmail-pop3-uidl This allows imapc to generate GMail POP3 compatible UIDL so that pop3-migration plugin isn't needed.

imapc: Added imapc_features=gmail-labels-keyword This is a bit kludgy feature mainly intended for migrations from GMail. Unfortunately I couldn't figure out any nicer way to do this for now. GMail's "All Mail" folder contains all messages in all folders, but it also contains some messages that don't exist in other folders. For migrations we want to copy only those messages that don't exist elsewhere. This can now be achieved with something like: doveadm -o imapc_features='gmail-labels-keyword ...' \ backup -F '-$GmailHaveLabels' mdbox:~/mdbox Note that dsync can't handle inserting mails into folders, so if doveadm backup is already run once and one of the existing mails loses all labels, doveadm backup will delete the whole folder and start again.

imapc: Added imapc_sasl_mechanisms setting The first supported SASL mechanism is used, otherwise the login fails entirely.

Updated copyright notices to include year 2014.

imapc: Added imapc_feature fetch-header. It uses FETCH BODY.PEEK[HEADER.FIELDS (...)] whenever possible instead of fetching the entire header.

imapc: Changed imapc_user setting's default to empty.

Moved ssl_client_ca_dir and ssl_crypto_device to mail_storage_settings. Probably could also be moved to master_service_settings, but that makes accessing them a bit more tricky with the current code.

lib-storage: Replaced pop3c_ssl_ca_dir and imapc_ssl_ca_dir with generic ssl_client_ca_dir.

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

Updated copyright notices to include year 2013.

imapc: And another compile fix.. Using the macro would have required config/all-settings.c to include imapc-client.h, which is a bit too much trouble just for this.

imapc: Compile fix for previous change.

imapc: Added IMAPC_DEFAULT_MAX_IDLE_TIME macro.

imapc: Added imapc_max_idle_time setting to force activity on connection. Reducing this from the default 29 minutes should help when there's a stateful firewall between imapc and the backend server.

imapc: Added imapc_list_prefix setting to limit what mailboxes are accessed.

imapc: Added guid-forced feature to use SHA1(message) as GUID.
