[Dovecot] More effective mailbox fetching over high RTT link
by Andrzej Adam Filip 13 Aug '09

13 Aug '09

Could you offer some suggestion how to fetch mailbox content over high RTT link (with negligible packet loss)? Currently I use IMAP+IDLE *but* it fails to use full available bandwidth due to high RTT and "send command wait for response" nature of POP3 and IMAP4 protocols. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Learning without thought is labor lost; thought without learning is perilous. -- Confucius

[Dovecot] sieve: variable extension?
by Lev Serebryakov 13 Aug '09

13 Aug '09

Hello, Dovecot. Does dovecot sieve supports variable extension (rfc5229)? It is very useful for users with large amount of mailing lists, as it allows to write only one rule for all lists (filtering by List-Id). If it is not supported, is here any plans to support it? I can try to implement it, but I don't want to duplicate work, if somebody has this extension in pipeline. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Tilde expansion in ManageSieve for dovecot-1.1.
by Stephen O'Dor 13 Aug '09

13 Aug '09

Greetings all, I'll skip the details of the setup, except to say that it has a non-standard (and non-templateable) home directory path for virtual users. Ran into the following problem when a debian (possibly from backports) packaged dovecot-1.1.2 was upgraded to a dovecot-1.1.13-2~bpo50+1 (definately from backports): sieve-storage: root directory specified by mail data does not exist: ~/Maildir After some analysis, it would appear that ManageSieve (looks like 0.10.4 is included in the debian backports) doesn't do the tilde expansion before doing a stat test to see if the ~/Maildir exists. Here's a quick diff of the change I made to make it work: sodor@madawg:~/tmp/deb-dove/dovecot-1.1-managesieve-0.10.4/src/lib-sievestorage$ diff sieve-storage.c ../../../sieve-storage.c 73c73 < const char *root_dir, *dir, *p, *d; --- > const char *root_dir, *dir, *p, *d, *home; 127a128,133 > /* expand tilde in root so that the stat below works */ > home = getenv("HOME"); > if (home != NULL && *home != '\0') { > root_dir = home_expand_tilde( root_dir, home ); > } > I'm not sure if this was the best way to fix this (or if this is even a bug, I might just have a crazy setup). Thanks, -Steve

[Dovecot] Dovecot proxy server
by michel＠casa.co.cu 13 Aug '09

13 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS?

[Dovecot] user_global_* ldap deliver
by Noel Leistad 12 Aug '09

12 Aug '09

Searched archive, but failed to find... :-( "deliver" does not honor user_global_* from dovecot-ldap.conf or userdb static{} also it looks like delivery attempts being made to %n/Maildir/cur ?? one other curious thing, use of ${recipient} in master.cf|deliver command causes the "passdb ldap" lookups to be completely ignored? only checks passdb and ignores userdb compleletely? IF I put noel(at)metc(dot)net into passwd.dovecot using passdb flatfile, auth and delivery seem to work. Thanks for any direction. I lament I couldn't get farther on my own.

[Dovecot] Dovecot Versions and Debian
by Mario Antonio 12 Aug '09

12 Aug '09

If you want to run Dovecot on Debian Lenny for a Production System (with Fast Upgrade System for Security Patches), What would you recommend? Stick to the current port with Dovecot Version 1.0.15 (1:1.0.15-2.3) Use Backports Version 1.1.13 (1:1.1.13-2~bpo50+1) or Use any of the packages from: ---------------------------------------------------------------------------------------------------------------------- Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main ---------------------------------------------------------------------------------------------------------------------- Do you find any compelling reason for not using version 1.0.15 ? (Besides of ACL limitations ...) Regards, Mario Antonio

[Dovecot] sieve/managesieve and spam filtering
by Charles Sprickman 11 Aug '09

11 Aug '09

Hello all, I've got a test environment setup in preparation for a move from qmail/vpopmail/courier to postfix/padmin/dovecot. I have a number of questions that seem to span multiple pieces of software, and this is one of them... Our policy with spam filtering is that a user should be able to turn it off (ie: not put tagged spam into a spam folder, but deliver to their inbox) if they want to. Currently qmailadmin and a custom squirrelmail plugin give people the option to do this by dumping a .qmail file in their directory that calls a common maildrop script that will deliver spam to the spam folder. It looks like I can emulate this with sieve and something that can speak to Dovecot's managesieve server. Where I'm stuck is that if I want users to be able to do other custom filtering using sieve, how do I go about making sure that my common spam delivery rule does not get clobbered? This really has me a bit stumped. I see there's a global sieverc that can be included, but I need something along the lines of a per-user include that brings in the spam filtering rule that will "stick" until the user explicitly deletes it. Any ideas? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] Index cache file problems in Dovecot 1.2.0
by Chris Wakelin 11 Aug '09

11 Aug '09

I've been seeing lots of index cache file errors (using mbox on Solaris 8 sparc 64-bit, but with 32-bit Dovecot) since I switched my account to Dovecot 1.2.0 (we're still on 1.0.15 mostly, but I'm hoping to upgrade to 1.1.17+ this summer, or 1.2.x if it's stable enough). e.g. Error: Corrupted index cache file <path>/.imap/INBOX/dovecot.index.cache: field index too large (47 >= 25) I've tried renaming/removing the .imap/INBOX directory, but the "Corrupted index cache file" errors return within a day or so. This morning, Thunderbird got itself in a mess retrying something that caused multiple core dumps: > Jul 14 08:52:53 dovecot: Error: child 17694 (imap) killed with signal 10 (core dumped) > Jul 14 08:52:54 dovecot: Error: child 17697 (imap) killed with signal 10 (core dumped) > Jul 14 08:52:55 dovecot: Error: child 17700 (imap) killed with signal 10 (core dumped) Here's a backtrace > #0 mail_cache_get_record (cache=0x124e28, offset=289, rec_r=0xffbeeb6c) > at mail-cache-lookup.c:30 > 30 if (rec->size < sizeof(*rec)) { > (gdb) bt > #0 mail_cache_get_record (cache=0x124e28, offset=289, rec_r=0xffbeeb6c) > at mail-cache-lookup.c:30 > #1 0x84e2c in mail_cache_lookup_iter_next_record (ctx=0xffbeeb60) > at mail-cache-lookup.c:186 > #2 0x84f14 in mail_cache_lookup_iter_next (ctx=0xffbeeb60, field_r=0xffbeeb50) > at mail-cache-lookup.c:219 > #3 0x85650 in mail_cache_lookup_headers_real (view=0x128510, dest=0x129728, > seq=11416, field_idxs=0xffbeec74, fields_count=2) > at mail-cache-lookup.c:500 > #4 0x85848 in mail_cache_lookup_headers (view=0x128510, dest=0x129728, > seq=11416, field_idxs=0xffbeec74, fields_count=2) > at mail-cache-lookup.c:555 > #5 0x6ba94 in index_mail_get_raw_headers (mail=0x128f20, > field=0xff142ee8 "Message-ID", value_r=0xffbeecfc) > at index-mail-headers.c:614 > #6 0x6c084 in index_mail_get_first_header (_mail=0x128f20, > field=0xff142ee8 "Message-ID", decode_to_utf8=false, value_r=0xffbeede4) > at index-mail-headers.c:771 > #7 0x7893c in mail_get_first_header (mail=0x128f20, > field=0xff142ee8 "Message-ID", value_r=0xffbeede4) at mail.c:118 > #8 0xff1419a0 in mail_log_add_hdr (mail=0x128f20, str=0x10edc8, > name=0xff142d68 "msgid", header=0xff142ee8 "Message-ID") > at mail-log-plugin.c:277 > #9 0xff141c5c in mail_log_action (dest_trans=0x128f20, mail=0x128f20, > event=MAIL_LOG_EVENT_DELETE, data=0x0) at mail-log-plugin.c:318 > #10 0xff141e5c in mail_log_mail_update_flags (_mail=0x128f20, > modify_type=MODIFY_ADD, flags=12) at mail-log-plugin.c:376 > #11 0x78af8 in mail_update_flags (mail=0x128f20, modify_type=MODIFY_ADD, > flags=12) at mail.c:184 > #12 0x2ab3c in cmd_store (cmd=0x11bec8) at cmd-store.c:192 > #13 0x2b5f8 in cmd_uid (cmd=0x11bec8) at cmd-uid.c:27 > #14 0x2ccc4 in client_command_input (cmd=0x11bec8) at client.c:611 > #15 0x2cb68 in client_command_input (cmd=0x11bec8) at client.c:660 > #16 0x2cd4c in client_handle_next_command (client=0x11bc40, > remove_io_r=0xffbef23f) at client.c:701 > #17 0x2ce40 in client_handle_input (client=0x11bc40) at client.c:713 > #18 0x2cf78 in client_input (client=0x11bc40) at client.c:752 > #19 0xc6c04 in io_loop_handler_run (ioloop=0x1186d8) at ioloop-poll.c:203 > #20 0xc63f4 in io_loop_run (ioloop=0x1186d8) at ioloop.c:338 > #21 0x369f4 in main (argc=1107968, argv=0xffbef484, envp=0xffbef494) > at main.c:323 I didn't have these problems with 1.1.x.
