[Dovecot] Listening only on localhost
by tobias-mail＠gmx.net 02 Nov '07

02 Nov '07

Hi! I've got dovecot 1.0.rc15. I want dovecot to listen only on localhost for imap, and on any interfaces for imaps. So I put the following into my config: protocol imap { listen = 127.0.0.1:143 ssl_listen = *:10993 .. } dovecot -n correctly reports: listen: 127.0.0.1:143 ssl_listen: *:10993 But I can still do a 'telnet MY_HOST 143' from the outside, and 'netstat -pltn | grep dovecot' reports: [ip changed ;)] tcp 0 0 77.my.ip.253:10993 0.0.0.0:* LISTEN 4847/dovecot tcp 0 0 77.my.ip.253:143 0.0.0.0:* LISTEN 4847/dovecot Am I doing something wrong? Or is there a bug? -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS. Alle Infos und kostenlose Anmeldung: http://www.gmx.net/de/go/freemail

[Dovecot] caching custom headers (via plugins)
by Paolo 02 Nov '07

02 Nov '07

hi, currently dovecot caches on disk some most common headers. Is it possible to tweak such headers list via plugins, eg to cache custom X-* headers, or do I need to hack the actual index/cache src? if so, which are the .c/.h files to touch? thanks -- paolo GPG/PGP id:0x1D5A11A4 - 04FC 8EB9 51A1 5158 1425 BC12 EA57 3382 1D5A 11A4

[Dovecot] Errors in Dovecot 1.0.5
by Jeff Tucker 02 Nov '07

02 Nov '07

Hello, I am running Dovecot 1.0.5 and seem to have lots of errors in my Dovecot logs. The worst errors are things like: Oct 30 16:11:42 delta2 dovecot: IMAP(x): Corrupted transaction log file /home/spamcop-net2/deputies/dovecot.index.log: end_offset (392) > current sync_offset (388) Oct 30 16:11:42 delta2 dovecot: IMAP(x): file mail-index-sync-update.c: line 841 (mail_index_sync_update_index): assertion failed: (view->hdr.messages_count == map->hdr.messages_count) Oct 30 16:11:42 delta2 dovecot: IMAP(x): Raw backtrace: imap [0x462a7e] -> imap [0x46234c] -> imap(mail_index_sync_update_index+0x7b2) [0x44a982] -> imap(mail_index_sync_commit+0xe7) [0x447f87] -> imap(maildir_sync_index_finish+0xd2) [0x420b32] -> imap [0x4225af] -> imap(maildir_storage_sync_init+0x63) [0x4227b3] -> imap(imap_sync_nonselected+0xf) [0x41be9f] -> imap(_cmd_select_full+0xc5) [0x413f95] -> imap(cmd_select+0xb) [0x41411b] -> imap [0x415a87] -> imap [0x415b2c] -> imap(_client_input+0x75) [0x415cd5] -> imap(io_loop_handler_run+0xee) [0x4684ce] -> imap(io_loop_run+0x2d) [0x46797d] -> imap(main+0x3e3) [0x41d7b3] -> /lib/libc.so.6(__libc_start_main+0xdb) [0x2aaaaace049b] -> imap [0x410cca] When this happens, my users just get timeouts trying to do stuff. I have my messages (maildirs) and indices all stored on NFS. For locking, I have mmap_disable = yes and lock_method = dotlock Do you have any idea what is going on here? In general, I get tons of errors about corrupted transaction log files for all users. Is this normal? Thanks Jeff

[Dovecot] v1.1.beta5 released
by Timo Sirainen 02 Nov '07

02 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz.sig APPEND should be working now. Also lots of fixes to handling namespace prefixes and namespaces where virtual separator differs from real separator. zlib plugin now supports opening compressed maildir files. This is done for files that have Z flag. SORT still assert-crashes sometimes. Would be great if someone could show me how to reproduce it. SEARCH TEXT or Squat indexes apparently still have some problems, but I couldn't reproduce them (http://dovecot.org/list/dovecot/2007-October/026254.html)

[Dovecot] Bug within Authentication Caching
by Matthias Waffenschmidt 02 Nov '07

02 Nov '07

Hello, there seems to be a bug in the authentication caching code when using it in combination with username_translation (using the current version 1.0.7 on FreeBSD 6). I've set username_translation to +@:@ to allow usernames of the form test+dom.ain or test:dom.ain (historical reasons force us....). If someone has a successful login using the username test(a)dom.ain, the subsequent authentication information is read from the cache, no matter which of the 3 possible usernames the client uses the next time. But if someone has a successful login using the username test+dom.ain, the following data has or has not been found in the cache: test+dom.ain: miss test(a)dom.ain: miss test:dom.ain: hit If the first username is test:dom.ain the behaviour is the following: test:dom.ain: miss test(a)dom.ain: miss test+dom.ain: hit I've added the information if the username changes for better debugging possibilities. In practice the username is of course always the same. The complete authentication part of the tested config: auth default: cache_size: 10000 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@:+ username_translation: +@:@ verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /var/pop/%d/Accounts.passwd userdb: driver: static args: uid=70 gid=70 home=/var/emtpy It looks as if Dovecot does some wrong username translations before inserting/lookup up the data in the cache. BTW: a SIGUSR2 signal to the dovecot-auth process does not give any information as suggested in http://wiki.dovecot.org/Authentication/Caching. Please do not only answer to the list as I am not subscribed.
