[Dovecot] MD5 to CRAM-MD5 password conversion?
by David Jonas 21 Sep '10

21 Sep '10

We have a plethora of accounts for which we would like to enable CRAM-MD5 but their passwords are stored as MD5 hashes. Is there anything we can do? Can we take a linux MD5 hashed password (e.g. $1$fac330ee$wd6Tll...) and convert it to dovecot's CRAM-MD5 format (e.g. {CRAM-MD5}b3f297...)? Thanks!

[Dovecot] understand the struct message_header_line
by Alex Baule 21 Sep '10

21 Sep '10

Timo... Using the src/lib-mail/test-istream-header-filter.c as example, and following your tips to jump my desired header value, but i need to store the value from the Header filtered. In the Exemple, the callback is this: static void filter_callback(struct message_header_line *hdr, bool *matched, void *context ATTR_UNUSED) { if (hdr != NULL && hdr->name_offset == 0) { /* drop first header */ *matched = TRUE; } } What i try to understand is how the structs work, it's save the entire header or every line from header call the callback function ? hdr->name_offset is the size of elements in the struct ? (like a array of message_header_line) The void *context ATTR_UNUSED i can pass what i want to change ? like a pointer to a variable ?

[Dovecot] doveadm-expunge debug message clarifications
by LEVAI Daniel 21 Sep '10

Hi! I have some questions about doveadm-expunge's debug messages. # /usr/local/bin/doveadm -Dv expunge -u <user> mailbox 'sa.*' SAVEDBEFORE 6h doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib20_expire_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/doveadm/lib10_doveadm_expire_plugin.so doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: expire: Searching only users listed in expire database ^^^^ That I don't understand. Does this mean that I can only specify users with the '-u' parameter from the list from the expire database, which is configured with: dict { expire = pgsql:/etc/dovecot/dovecot-sql.conf } If I don't specify a user with '-u', then nothing gets expunged, so it doesn't get the list of users from the expire database. doveadm(<user>): Debug: expunge: box=sa.spam uid=6376 doveadm(<user>): Debug: expunge: box=sa.spam uid=6377 doveadm(<user>): Debug: expunge: box=sa.spam uid=6378 doveadm(<user>): Debug: expunge: box=sa.spam uid=6379 doveadm(<user>): Debug: expunge: box=sa.spam uid=6380 doveadm(<user>): Debug: expunge: box=sa.spam uid=6381 doveadm(<user>): Debug: expunge: box=sa.spam uid=6382 doveadm(<user>): Debug: expunge: box=sa.spam uid=6383 doveadm(<user>): Error: net_connect_unix(/var/dovecot//dict) failed: Permission denied # ls -la /var/dovecot/dict srw------- 1 root wheel 0 Sep 21 09:47:00 2010 /var/dovecot/dict= service dict { chroot = client_limit = 1 drop_priv_before_exec = no executable = dict extra_groups = group = idle_kill = 0 s privileged_group = process_limit = 0 process_min_avail = 0 protocol = service_count = 0 type = unix_listener dict { group = mode = 0600 user = } user = $default_internal_user vsz_limit = 4294967295 } What is trying to use that socket when I'm expunging mails?

[Dovecot] tags disappear in Thunderbird
by Iv Ray 21 Sep '10

21 Sep '10

We have - Dovecot 1.0.15 (the default on Debian Lenny stable) Thunderbird 3.1.4 In our installation the Inbox is a mbox and the other folders are maildir. When we tag messages in Inbox, the tags disappear after a while. In the other folders they stay. I found two possible solutions suggested - 1. Set mbox_lazy_writes=no 2. Convert the Inbox to maildir What would be the best approach in your opinion? Would suggest not following the Debian Lenny stable version (1.0.15), but compiling the current stable Dovecot? Thank you very much, Iv

[Dovecot] Problem installing latest dovecot w vpopmail
by Joe ＠ 3ZZZ 21 Sep '10

21 Sep '10

Hello - I am trying to migrate my dovecot installation from an older server running version 1.x to the latest 2.0.3 When I run configure --with-vpopmail, it bombs pretty quick as follows: ./configure --with-vpopmail checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether to enable maintainer-specific portions of Makefiles... no configure: error: vpopmail support is broken. fix it or access its db another way. however, vpopmail seems to be working fine, i can add domains from vpopmail/bin/vadddomain and they show up in the database just fine. So why do I receive this error and how can i troubleshoot? thank you very much in advance, Joe

[Dovecot] configure error

Hi all, on my system ("AIX 6.1" with "xlc -q64") the "configure" script for "dovecot-2.0.2" breaks with: checking whether fd passing works... no configure: error: fd passing is required for Dovecot to work in config.log: configure:19524: ./conftest configure:19524: $? = 1 configure: program exited with status 1 It seems, that the last changes in "src/lib/fdpass.c" are the reason. ----------------------------------------------------------------------------- 109a110 > void *cmsg_data; 132c133,134 < *((int *) CMSG_DATA(cmsg)) = send_fd; --- > cmsg_data = CMSG_DATA(cmsg); > *(int *)cmsg_data = send_fd; 166a169 > void *cmsg_data; 196,197c199,202 < else < *fd = *((int *) CMSG_DATA(cmsg)); --- > else { > cmsg_data = CMSG_DATA(cmsg); > *fd = *(int *)cmsg_data; > } ----------------------------------------------------------------------------- Using the old version (from "src/lib/fdpass.c") make no trouble. -- Kind regards / Mit freundlichen Grüßen A.

[Dovecot] dovecot-2.0.3 - can not upload message, over quota
by LEVAI Daniel 20 Sep '10

20 Sep '10

Hi! I've upgraded to 2.0.3 from 1.2, and it is so far so good. I especially like the new doveadm tool. I have only one tiny problem: Every time I try to upload a message to the server (eg. to a 'Sent' folder, while sending a message), it fails with an error saying I'm over my quota. I'm using mutt, and this is the exact message I get in mutt: [OVERQUOTA] Quota exceeded (mailbox for user is full) Now this is not true, because dovecot-lda can save message to any of my folders, and doveadm says I have no quota (which is true): # doveadm quota get -u <user> Quota name Type Value Limit % User quota STORAGE 1075010 - 0 User quota MESSAGE 26750 - 0 Dovecot logs say nothing about this. Why is that error message then? (I must admit that I didn't try with another mail client.) I've tried to recalc the quota with doveadm but no luck. doveconf -n: # 2.0.3: /etc/dovecot/dovecot.conf # OS: OpenBSD 4.7 i386 default_internal_user = _dovecot default_login_user = _dovenull dict { expire = pgsql:/etc/dovecot/dovecot-sql.conf } info_log_path = /var/log/mail/dovecot.info listen = 127.0.0.1 log_path = /var/log/mail/dovecot.log mail_location = maildir:~/Maildir/ mail_plugins = quota expire passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { expire = sa.* 1 expire_dict = proxy::expire quota = maildir:User quota quota_rule = *:storage=100M quota_rule2 = Trash:storage=+50M } protocols = pop3 imap userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota } protocol pop3 { mail_plugins = $mail_plugins pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { deliver_log_format = msgid=%m, from=%f, subject=%s: %$ mail_plugins = $mail_plugins sieve sendmail_path = /usr/local/sbin/sendmail } TIA, Daniel -- LÉVAI Dániel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F
