[Dovecot] Does dovecot proxy support message caching?
by Edward Carraro 03 Mar '11

03 Mar '11

For example, say the connection between the user and the dovecot proxy is fast/cheap, but the connection from the proxy to the dovecot imap backend server is costly. is there a way to set up the proxy to cache messages to allow faster loading? if so, does it have different levels of caching (full message, headers only, etc)? I'm using dovecot 2.0.9 for both the proxy and the imap backend. if not, is there something that can work with dovecot to allow this? Thanks!

[Dovecot] Segfault in managesieve with "sieve_extensions = -redirect"
by Sven Hartge 03 Mar '11

03 Mar '11

Hi! I've got a segfault in managesieve while using: sieve_extensions = -vacation -reject -spamtest -virustest -enotify -redirect The problem seems to lie in "-redirect". Reason for excluding "redirect" from sieve is my users should not use sieve to forward or redirect mails but use an external method (web-script to set LDAP attribute) which checks several things like active spam-checker, existing target mailbox, etc. The version ov dovecot ist 1:2.0.9-1~3.gbp785ad1~dvz60+1 on Debian Squeeze which is from the Debian maintainers git repository recompiled on Squeeze (I know, pretty wild.) doveconf -n and backtrace follow: -----------------------8<--------------------------------------------- # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0 auth_username_format = %Ln dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_gid = 1000 first_valid_uid = 1000 last_valid_gid = 1000 last_valid_uid = 1000 mail_access_groups = virtmail mail_gid = virtmail mail_location = mdbox:~/mdbox mail_plugins = " quota zlib" mail_uid = virtmail mdbox_rotate_interval = 23 hours mdbox_rotate_size = 25 M namespace { hidden = yes inbox = yes list = yes location = prefix = INBOX. separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { quota = dict:Benutzer-Quota::proxy::quota quota_rule = *:storage=2G sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = -vacation -reject -spamtest -virustest -enotify -redirect zlib_save = gz zlib_save_level = 6 } postmaster_address = postmaster(a)th-mittelhessen.de protocols = imap pop3 sieve service dict { unix_listener dict { group = virtmail mode = 0660 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } protocol lmtp { mail_plugins = " quota zlib sieve" } protocol lda { mail_plugins = " quota zlib sieve" } protocol imap { mail_plugins = " quota zlib imap_quota imap_zlib" } -----------------------8<--------------------------------------------- (gdb) bt full #0 sieve_extensions_set_string (svinst=<value optimized out>, ext_string=<value optimized out>) at sieve-extensions.c:567 ext = 0x0 op = 0 '\000' name = 0x2375331 "redirect" _data_stack_cur_id = 2 ext_reg = 0x23856c8 ext_names = 0x2375368 i = <value optimized out> ext_count = <value optimized out> relative = true #1 0x00007fb2db4207c2 in sieve_extensions_init (svinst=0x2385680) at sieve-extensions.c:256 extensions = <value optimized out> ext = <value optimized out> #2 0x00007fb2db426914 in sieve_init (env=0x40d700, context=<value optimized out>, debug=false) at sieve.c:83 svinst = 0x2385680 uint_setting = 0 size_setting = 37179544 pool = 0x2385660 #3 0x00000000004085ff in managesieve_capabilities_dump () at managesieve-capabilities.c:125 svinst = <value optimized out> notify_cap = <value optimized out> #4 0x0000000000408af5 in main (argc=4, argv=0x237d370) at main.c:273 set_roots = {0x610040, 0x0} service_flags = <value optimized out> storage_service_flags = 0 postlogin_socket_path = 0x0 username = 0x0 c = <value optimized out> -----------------------8<--------------------------------------------- Grüße, Sven. -- Sig lost.

[Dovecot] Error purging mdbox (damaged) mailbox
by Javier Miguel Rodríguez 02 Mar '11

02 Mar '11

We are stress testing our preproduction system. One of the "evil" tests we made was putting our mailboxes filesystem in read-only in the middle of smtp(+lda) delivery. When we try to purge one of the affected mailboxes we get error like the followings: / doveadm(lbandera@mysite): Panic: file mdbox-purge.c: line 225 (mdbox_purge_save_msg): assertion failed: (ret == (off_t)msg_size) doveadm(lbandera@mysite): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943bab0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x3b0943bb95] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943b4c3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_purge+0xe83) [0x3b0986f0c3] -> /usr/bin/doveadm [0x408d65] -> /usr/bin/doveadm [0x4093c1] -> /usr/bin/doveadm(doveadm_mail_single_user+0x9d) [0x4094ed] -> /usr/bin/doveadm [0x4096fe] -> /usr/bin/doveadm(doveadm_mail_try_run+0xb7) [0x409b37] -> /usr/bin/doveadm(main+0x2fc) [0x40dddc] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b0881d994] -> /usr/bin/doveadm [0x408c39]/ / doveadm(leonvela@mysite): Panic: file mdbox-purge.c: line 225 (mdbox_purge_save_msg): assertion failed: (ret == (off_t)msg_size) doveadm(leonvela@mysite): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943bab0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x3b0943bb95] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943b4c3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_purge+0xe83) [0x3b0986f0c3] -> /usr/bin/doveadm [0x408d65] -> /usr/bin/doveadm [0x4093c1] -> /usr/bin/doveadm(doveadm_mail_single_user+0x9d) [0x4094ed] -> /usr/bin/doveadm [0x4096fe] -> /usr/bin/doveadm(doveadm_mail_try_run+0xb7) [0x409b37] -> /usr/bin/doveadm(main+0x2fc) [0x40dddc] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b0881d994] -> /usr/bin/doveadm [0x408c39]/ The mailboxes are damaged, but maybe doveadm should not crash on them, should handle the error more gracefully and exit with a error status.

[Dovecot] Dovecot+Postfix+Mysql+quotas doesn't work

Hi ! I'm using postfix with mysql, dovecot and squirrelmail for WEBMAIL In my dovecot.conf I've: plugin { quota = maildir:User quota quota2 = maildir:Shared quota:ns=Public/ quota_rule = *:storage=400M quota_rule2 = Trash:storage=100M quota_exceeded_message = Quota excedida. Por favor, exclua alguns emails! quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } In my webmail, he informs me that I'm using the percentage of quota. But I can't make the TRASH folder is ignored. That is, I can't put a higher limit on it than the others. Am I doing something wrong? Another thing. I'm not receiving message of quota exceeded.

[Dovecot] lazy_expunge, 2 questions
by Hajo Locke 01 Mar '11

01 Mar '11

Hello List, do some tests with lazy_expunge i have 2 short questions. is it possible to set folder for expunged messages to read-only so no user is possible to really delete them? i can use mdbox for expunged-folder. but would'nt it be more functional to use maildir to have possibility to delete separate mails? when using mdbox the clean up by cron would effect always multiple messages with different ages? Thanks, Hajo

[Dovecot] 1.0.15 -> 2.x upgrade for mass hosting environment
by lists＠truthisfreedom.org.uk 01 Mar '11

01 Mar '11

Hi all, We're looking at upgrading our current mail platform from 1.0.15 to 2.x to take advantage of the new director functionality. Our main concern is the number of mailboxes involved (circa. 300K) and the rebuilding of the index files, especially as it seems that once you've upgraded, rolling back requires the deletion and recreation of all indices. Has anyone worked on an upgrade like this in the past? If so, do you have any war stories you can share either on or off list? Thanks in advance, Matt
