|---|---|
| 14753 | 1 - Unfinished extensions: MOVE, NOTIFY, BINARY |
| 2 - indexer-worker and maybe others (doveadm?) could support dropping privileges | |
| 3 permanently when service_count=1. Note that LMTP can't with multiple RCPT | |
| 4 TOs. | |
| 5 - after reading whole message text, update has_nul-state to cache | |
| 6 - if indexpvt is enabled, mailbox_list_indexes should go there? at least | |
| 7 private flags are otherwise problematic.. possibly only for shared/public | |
| 8 mailboxes?.. | |
| 9 - catenate: {1234} and {1234+} error handling is wrong for both | |
| 10 - index_mail_parse_headers() etc. message_parsers don't check for stream errors | |
| 14585 | 11 - FIFOs maybe should be counted as connections, but unlisten should |
| 12 unlink+reopen it in master? | |
| 13 - mailbox list indexes + imaptest test=tests fails | |
| 14 - mailbox_enable() -> mail_user_enable()? | |
| 15 - mailbox_info.name -> vname | |
| 16 - change proxy TTL so it stops at 1? | |
| 17 - istream-concat | |
| 14140 | 18 - lmtp client/proxy: Handle multiline replies better |
| 19 - recreate mailbox -> existing sessions log "indexid changed" error | |
| 13907 | 20 - add message/mime limits |
| 13677 | 21 - imapc: |
| 22 - prefetching to THREAD and SORT | |
| 23 - check all imap extensions and see if some don't work (condstore) | |
| 13900 | 24 - per-namespace imapc_* settings? create a way to "copy" a settings struct, |
| 25 so mail_storage_settings are copied to mail_namespace_settings. use the | |
| 26 change tracking to figure out what settings are namespace-specific. | |
| 13677 | 27 |
| 13900 | 28 - imap: list (special-use recursivematch) "" % doesn't work |
| 29 - passdb, userdb { username_format } that doesn't permanently change | |
| 30 the username | |
| 13470 | 31 - mdbox/sdbox index rebuild -> quota rebuild? |
| 13360 | 32 - solr separate attachments (patch) |
| 33 - sql connection pooling: Count lookup latencies, avoid servers with | |
| 13777 | 34 significantly higher latencies. optionally use the secondary server only |
| 35 as fallback | |
| 13360 | 36 - maildir_storage_sync_force() shouldn't do anything except find the new |
| 37 file, don't go expunging any more stuff or we could get recursively back to | |
| 38 where we started, and stuff would break | |
| 39 - imap: append/copy could trigger indexing (optionally) | |
| 40 - fuzzy: be fuzzy about date/size | |
| 12756 | 41 - mailbox list index: |
| 42 - with in-memory indexes be sure to refresh it more often | |
| 43 - refreshing could refresh only the parts that are actually requested, | |
| 44 e.g. % | |
| 45 - mailbox_get_metadata(guid) could be optimized | |
| 46 - virtual could use it to avoid keeping all mailboxes open | |
|

48 - dsyncing between two namespace separators is probably broken.. |
| 12579 | 49 - remove mail_deliver_session after all, do all the stuff transparently |
| 50 by hooking into mailbox_copy(). | |
| 51 - use this hook also to do the mail deduplication: 1) sort all destination | |
| 52 users, 2) create mail_user only once for each user, 3) remember in | |
| 53 src_mail the previously copied mail, 4) use that for mailbox_copy()ing | |
| 54 to following recipients | |
| 12551 | 55 - notify_sync() could have "what changed" struct with old/new flags |
| 12546 | 56 - maildir: copy dovecot-shared file from parent mailbox, not root. |
| 57 - if global ACL path points to a file instead of a directory, read all of | |
| 58 them from there. support wildcards in names. | |
| 59 | |
| 12476 | 60 - master passdb preserves userdb_* extra fields. should it preserve |
| 61 non-userdb_* extra fields too? | |
| 12400 | 62 - imap, pop3: if client init fails, wait a second or two before disconnecting |
| 63 client. | |
| 64 - doveadm search savedbefore 7d could be optimized in large mailboxes.. | |
| 12336 | 65 - mdbox: storage rebuilding could log about changes it does |
| 12400 | 66 - mdbox: broken extrefs header keeps causing index rebuilds |
| 12336 | 67 - cache: mail_cache_lookup() should be able to return mail_cache_add()ed |
| 68 fields even before they've been flushed to disk. this is useful when copying | |
| 69 messages and some plugin (e.g. mail_log) fetches some fields that are | |
| 70 already added to cache (to avoid opening and parsing the message) | |
| 12231 | 71 - doveadm -A <<EOF expunge + purge + EOF |
| 72 - sent, drafts: .Sent/dovecot.index: modseq_hdr.log_offset too large | |
| 12181 | 73 - mail_max_lock_timeout error could be reported more nicely, also ones coming |
| 74 from lib-index | |
| 75 - dsync: if mailbox is renamed due to it being invalid, its subscription | |
| 76 isn't renamed | |
| 12095 | 77 - sql pool: if async query is pending and sync query is sent and there |
| 78 are no more empty connections, it should flush the async query first | |
| 11683 | 79 - NTLMv1 and LM should be disabled if disable_plaintext_auth=yes |
| 11387 | 80 - SEARCH SENT*/HEADER/etc. doesn't seem optimized when using with TEXT/BODY |
| 12476 | 81 - dict sql: support ignoring some search key hierarchies (e.g. acl "anyone") |
| 11273 | 82 |
| 10479 | 83 - mdbox |
| 11485 | 84 - dotlocking: cleanup should delete stale *.lock files |
| 10968 | 85 - purging seems to be inefficient. run imaptest for a while, get >500 |
| 86 files, start purging, it's slow until there are about 100 files left, | |
| 87 then the rest is suddenly fast. | |
| 88 - make sure that when reading mdbox mails sequentially the data is being | |
| 89 read from disk in n kB blocks and reads cross mail boundaries and when | |
| 90 reading the next mail it uses the previously read data in buffer | |
| 10479 | 91 - Add some kind of checksum about data+metadata and use it when checking |
| 92 consistency | |
| 10798 | 93 - figure out a way to efficiently trigger purging when user has too much |
| 94 mail expunged (e.g. keep track of total storage size, trigger purging | |
| 95 when it's 2*quota limit) | |
| 96 - keep track of total bytes in dbox storage in map header. also if | |
| 97 possible keep track of refcount=0 bytes. use these to optimize checks. | |
| 98 - save some stuff to map index header so we don't need to keep retrying | |
| 99 it. like when saving the lowest file_id which to bother checking. | |
| 100 - test crash-fixing | |
| 101 - mail_index_fsck() should perhaps cause dbox to be resynced? | |
| 10968 | 102 - optimize away reading file header? |
| 10479 | 103 - maildir: out-of-disk-space failures apparently cause all kinds of |
| 104 problems, e.g. "Expunged message reappeared", "Duplicate file entry"? | |
| 10163 | 105 - deliver -r <address> used as autoreplies' From-address? |
| 106 - add fd limit checks/warnings | |
| 10546 | 107 - istream-seekable is inefficient. it shouldn't be reading the temp file |
| 108 immediately after writing to it | |
| 10968 | 109 - config process is handling requests too slowly. maybe add some caching. |
| 110 - maybe config should return all of the protocol/local/remote overrides | |
| 111 when requested? then the caller could do a single lookup at start and | |
| 112 merge them later internally. this would really help login processes. | |
| 113 - ipv6: auth penalty should begin from /64 and gradually grow to /48 if | |
| 114 necessary. and the same could be done for ipv4 as well.. | |
| 10052 | 115 |
| 9559 | 116 - dsync: |
| 11683 | 117 - check for uid conflicts in the middle of mailbox based on next existing |
| 118 message, not previous | |
| 10479 | 119 - subscriptions syncing doesn't handle mixed hierarchy separators |
| 10798 | 120 - Can't rename mailbox INBOX_019acf2169c5784b307f000074ccac23 to INBOX: Target mailbox already exists |
| 11683 | 121 - copying can't work in non-full mode unless source mailbox is modified |
| 122 in some way. possibly add some COPY records to transaction log in future? | |
| 123 - superfast mode: when syncing changes within a mailbox, use modseqs to | |
| 124 figure out what has changed similar to QRESYNC. | |
| 10052 | 125 |
| 10479 | 126 - lda: add some -h 'Header: value' parameter that adds/replaces header |
| 10163 | 127 - ldap: fix multiple-gid support somehow |
| 9459 | 128 - search: use mail_get_parts() only when it's already cached. if it's not, |
| 129 add it to cache afterwards. | |

| 136 ^ appears to work now though, probably because of the added syncing stuff.. | |

| 139 and perhaps not delete the file. | |

146 imap_sync_deinit |
| 8555 | 147 - fsck -> log_file_tail_offset 2273345664 -> 996 -> |
| 148 mail-transaction-log.c: line 341 (mail_transaction_log_set_mailbox_sync_pos): | |
| 149 assertion failed: (file_offset >= log->head->saved_tail_offset) | |
| 11765 | 150 - virtual: If last message matching INTHREAD rule gets expunged, the rest of |
| 151 the thread doesn't go away | |
| 8488 | 152 - how do shared mailboxes work with plugins? |
| 153 - lazy-expunge, fts, etc.? | |
| 11974 | 154 - listescape+acl can't handle shared mailboxes with escape chars |
| 8488 | 155 - dovecot-acl-list: |
| 156 - how does it work with global acls? | |
| 157 - update immediately after SETACL: add/remove entries, update timestamps | |
| 158 - read the entire file to memory only once and keep it there, stat() later | |
| 159 to see if it has changed. if not, perhaps don't even bother stat()ing | |
| 160 dovecot-acl files? at least not that often.. | |
| 161 - fs quota: getquotaroot inbox vs. other-box should return different quotas | |
| 162 if two quotas are defined | |
| 8158 | 163 - new primes code: are hash tables now being resized too often? |
| 164 - auth_log_prefix setting similar to mail_log_prefix | |
| 165 | |
| 166 - thread indexes: if we expunge a duplicate message-id: and we have a sibling | |
| 167 with identical message-id:, we can probably just move the children? | |
| 168 (unless there are non-sibling duplicates) | |
| 169 - SEARCH INTHREAD requires no thread sorting by date - don't do it | |
| 170 - CONDSTORE: use per-flag/per-keyword conflict checking | |
| 171 - QRESYNC: Drop expunges from the middle of given seq sets if possible | |
| 172 - use universal hash functions? | |
| 173 | |
| 174 - UIDVALIDITY changed while saving -> sync errors | |
| 175 - mbox: copy to Trash, manually delete copied msg, change uidvalidity, | |
| 176 set nextuid=1, copy again -> error | |
| 177 - recent_uids assert at least with mbox | |
| 178 - quota fs: Should values returned by quota be divided by the actual | |
| 179 filesystem block size instead of hardcoded DEV_BSIZE? not with AIX.. | |
| 7259 | 180 - squat: |
| 7380 | 181 - wrong indexid |
| 182 - fts_build_init() assertion failed: (last_uid < last_uid_locked) | |
| 7259 | 183 - is locking done right? it reads header without file being locked? |
| 184 - split after ~8 bytes? | |
| 7391 | 185 - expunges are delayed until more mails are added |
| 7259 | 186 - test replacement chars (SEARCH / SORT / Squat) |
| 6987 | 187 |
| 7449 | 188 - DEBUG: buffer overflow checking code probably doesn't handle a successful |
| 189 t_try_realloc() or pool_alloconly_realloc() properly | |
| 8738 | 190 - ldap: |
| 13324 | 191 - sasl bind + auth_bind=yes should probably be doing only sasl binds.. |
| 12400 | 192 - support multiple connections for doing auth binds |
| 8738 | 193 - domain lookups which set the base for user lookup |
| 14140 | 194 - multiple ldap values could be joined into one field with specified |
| 195 separator (e.g. mail_access_groups=%{ldap:gidNumber:,}) | |
| 8738 | 196 - implement something like: |
| 197 user_attrs { | |
| 198 uid = %{ldap:uidNumber} | |
| 199 home = %{ldap:homeDirectory} | |
| 200 quota_bytes = *:bytes=%{ldap:quota} | |

Initial commit for v2.0 master rewrite. Several features are still missing.
Timo Sirainen <tss@iki.fi>

|
203 - maildir+pop3 fast updates: |
| 6105 | 204 - with locking enabled, pop3 could just keep the one and same sync lock and |
| 205 do the whole thing using sync transaction | |
| 206 - don't update dovecot-uidlist if dovecot.index.cache doesn't exist / | |
| 207 there's nothing to cache | |
| 208 - if all messages are expunged and there are no unknown extensions in index, | |
| 209 unlink dovecot.index and rotate log and add some initial useful info to | |
| 210 the log (uidvalidity, nextuid) | |
| 5621 | 211 |
| 6105 | 212 - maildir |
| 6987 | 213 - don't allow more than 26 keywords |
| 5621 | 214 |
| 5557 | 215 - file_cache: we're growing the mmap in page size blocks, which is horribly |
| 216 slow if mremap() doesn't exist. | |
| 217 | |
| 3087 | 218 - keywords: |
| 219 - add some limits to how many there can be | |
| 220 - don't return \* in PERMANENTFLAGS when we're full | |
| 221 - remove unused keywords? | |
| 2774 | 222 |
| 11273 | 223 - mail caching |
| 3904 | 224 - force bits should be used only for nonregistered fields |
| 225 - change envelope parsing not to use get_headers() so imap.envelope can | |
| 226 actually be cached without all the headers.. | |
| 6105 | 227 - if there's no other pressure for compression, we should do it when |
| 228 enough temp fields are ready to be dropped | |
| 3904 | 229 - we could try compressing same field values into a single |
| 230 location in cache file. | |
| 7259 | 231 - place some maximum limit of fields to cache file? maybe some soft and |
| 232 hard limits, so when soft limit is reached drop fields that have | |
| 233 been used only once. when hard limit is reached drop any fields to get | |
| 234 more space. all this to avoid cache file growing infinitely. | |
| 2774 | 235 |
| 3087 | 236 - mbox |
| 11273 | 237 - UID renumbering doesn't really work after all? |
| 12476 | 238 - still problems with CRLF mboxes.. especially with broken Content-Length |
| 239 headers (pointing between CR-LF?) | |
| 3904 | 240 - syncing existing indexes takes 4x longer than creating new one, why? |
| 241 - how well does dirty sync + status work? it reads the last mail every | |
| 242 time? not very good.. | |
| 243 - always add empty line. make the parser require it too? syncing should | |
| 244 make sure there always exists two LFs at end of file. raw-mbox-stream | |
| 245 should make sure the last message ends with LF even if it doesn't exist | |
| 246 in the file | |
| 247 - Quote "From ", unquote ">From " | |
| 4449 | 248 - COPY doesn't work to itself (lock assert crash, for now just disallowed) |
| 2143 | 249 |
| 250 - index | |
| 3087 | 251 - read-only support for mailboxes where we don't have write-access |
| 6105 | 252 - index file format changes: |
| 10968 | 253 - split to "old" and "new" indexes and try to avoid loading "old" into |
| 254 memory until needed | |
| 6105 | 255 - pack UIDs to beginning of file with UID ranges |
| 256 - use squat-like compressed uid ranges everywhere | |
| 6782 | 257 - write first extension intros in dovecot.index.log always with names |
| 258 - or better yet, drop the intro concept completely as it is now | |
| 259 - add "transaction boundaries" so we know which records belong to a | |
| 260 single transaction. | |
| 261 - only after that we can remove the transaction log offset | |
| 262 overwriting (otherwise we can get partial transactions in views) | |
| 2143 | 263 |
| 3087 | 264 - login |
| 265 - Digest-MD5: support integrity protection, and maybe crypting. Do it | |
| 266 through login process like SSL is done? | |
| 474 | 267 |
| 3087 | 268 - auth |
| 4449 | 269 - with blocking passdb we're not caching lookups if the password was wrong |
| 5557 | 270 - non-plaintext authentication doesn't support all features: |
| 271 - multiple passdbs don't work, only the first one is used | |
| 272 - auth cache's last_success password change check doesn't exist | |
| 9459 | 273 - auth_cache_negative_ttl doesn't check password mismatches |
| 4449 | 274 - dovecot-auth should limit how fast authentication requests are allowed |
| 275 from login processes. especially if there's one login/connection the speed | |
| 3087 | 276 should be something like once/sec. also limit how fast to accept new |
| 277 connections. | |
| 278 - support read-only logins. user could with alternative password get only | |
| 279 read-access to mails so mails could be read relatively safely with | |
| 280 untrusted computers. Maybe always send [ALERT] about the previous | |
| 281 read-only login time with IP? | |
| 282 | |
| 283 - ssl | |
| 284 - add setting: ssl_options = bitmask. by default we enable all openssl | |
| 285 workarounds, this could be used to disable some of them | |
| 286 - gnutls support isn't working | |
| 965 | 287 |
| 3087 | 288 - search |
| 6232 | 289 - message header search: we should ignore LWSP between two MIME blocks(?) |
| 290 - message_search_init() could accept multiple search keywords so we | |
| 1250 | 291 wouldn't need to call it separately for each one (so we wouldn't need |
| 292 to parse the message multiple times). | |
| 293 - Create our own extension: When searching with TEXT/BODY, return | |
| 294 the message text surrounding the keywords just like web search engines | |
| 295 do. like: SEARCH X-PRINT-MATCHES TEXT "hello" -> * SEARCH 1 "He said: | |
| 296 Hello world!" 2 "Hello, I'm ...". This would be especially useful with | |
| 297 the above attachment scanning. | |
| 0 | 298 |
| 3087 | 299 - general |
| 300 - things break if next_uid gets to 2^32 |
