imap doesn't like my passwd
by James 31 Jul '20

31 Jul '20

I spent days on this problem. I have dovecot setup to use SSL and IMAP. I also have a pop account that I had no trouble getting working. Both use PAM authentication on Linux. openssl s_client -connect localhost:993 a login test_user test_secure_password The response I got back was: a BAD Invalid characters in atom I changed the password to "abc" and it worked. The secure password used to work but it was a different architecture (x86_64 I think). The current architecture is armhf. It may be different versions of the software too. Dovecot v2.1.7

Warning: Failed to do incremental sync
by Laura Smith 08 Apr '20

08 Apr '20

Setup dovecot sync along the lines of (https://wiki2.dovecot.org/Replication) I am doing one way replication. The initial full replication happened without issue, but now I'm seeing these errors on the slave server: doveadm: Warning: /data/mail/foo/bar/Maildir/dovecot-uidlist: Duplicate file entry at line 26397: 1562173159.M215923P17350.mxp,S=2290,W=2339 (uid 143128 -> 143142) Warning: Failed to do incremental sync for mailbox Sent Messages, retry with a full sync (Modseq 1766 no longer in transaction log (highest=17617, last_common_uid=17559, nextuid=17560)) Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 2540 no longer in transaction log (highest=13870, last_common_uid=19912, nextuid=19913)) I guess dovecot automatically tries a full replication because eventually the messages get pushed and "sync failed" status changes from 'y' to '-'

[Dovecot] Postfixadmin/MySQL/Dovecot 2 and quota
by Matt 01 Apr '20

01 Apr '20

Hi all, I'm setting up a new email server based on the softwares list below: * Postfix * Dovecot 2.0.9 * MySQL * Postfixadmin 2.3.6 My current problem is I'm unsure whether quota feature is well configured or not. In order to test and validate, I use Roundcubemail GUI which provides percentage of the space used by the mailbox (quota should be applied per mailbox). Here, my dovecot configuration: dovecot.conf: dict { quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } dovecot-dict-quota.conf: connect = host=localhost dbname=postfix user=postfix password=postfix map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } dovecot-sql.conf.ext: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfix default_pass_scheme = PLAIN-MD5 password_query = SELECT username AS user, password, \ CONCAT('*:storage=', CAST(quota AS CHAR), 'b') AS quota_rule \ FROM mailbox WHERE username = '%u' AND active='1' user_query = SELECT maildir, 89 AS uid, 12 AS gid, \ concat('dict:storage=',floor(quota/1000),'::proxy::quotadict') AS quota, \ CONCAT('*:storage=', CAST(quota AS CHAR), 'b') AS quota_rule \ FROM mailbox WHERE username = '%u' AND active='1' conf.d/90-quota.conf: plugin { quota = dict:user::proxy::quotadict quota_rule2 = Trash:storage=+10%% } conf.d/20-imap.conf: protocol imap { mail_plugins = $mail_plugins imap_quota } When I check postfixadmin GUI, I can see that quota in realtime in quota2 table, no problem. But Roundcubemail cannot get this information and shows a unknown quota. If I add this line: quota_rule = *:storage=1G in conf.d/90-quota.conf file, it works, I mean roundcubemail gets and shows information (but not the one stored in db of course). I think I'm close to the right configuration but I need your help to complete this setup. Thank you in advance for your help. Best, Matt

mail_filter and mail_filter_out broken somewhere between 2.2.27 and 2.3.4, problem still exists in git
by Michael Fincham 03 Feb '20

03 Feb '20

Hi Dovecot folks, I recently reported this bug in Debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939442) after a stretch -> buster upgrade, however since I can reproduce it using the latest 2.4 from git I thought perhaps I ought to take it straight upstream. Here's the text I provided Debian about the issue, and below that I've included a syslog snip showing the same issue in a fresh build of git master as well. mail_filter_out seems to fully panic (backtrace below), whereas mail_filter is just behaving oddly. Thanks :) ***************************** Package: dovecot-core Version: 2.3.4.1-5+deb10u1 Severity: important Hi Dovecot maintainers, After upgrading from the latest stretch version of dovecot-core (2.2.27-3+deb9u5) to buster (2.3.4.1-5+deb10u1) the "mail filter" interface seems to have broken. This problem is also present in the sid version (2.3.7.2-1). Mail filter is used to run the content of messages being stored or retrieved through an arbitrary process. The interface used for the external process is described here: https://wiki.dovecot.org/Plugins/MailFilter It is expected that the process will be called with the arguments specified in the configuration then supplied a message body on stdin, however since upgrading it seems that the arguments are not being correctly passed, instead being all jammed in to $1 and separated by tabs, rather than expanded in to argv. Even stranger the first few lines of the body of the message appear in argv rather than in stdin... These reproduction steps were carried out on a fresh install of Debian Buster with the "dovecot-core" package installed initially from stretch then upgraded to the buster version, however this behaviour has also been observed on stretch systems after upgrading to buster. To reproduce, drop this minimalised config in to /etc/dovecot/conf.d/repro.conf: # Minimal maildir setup for LDA first_valid_uid = 0 mail_location = maildir:~/Maildir userdb { driver = static args = allow_all_users=yes uid=mail gid=mail home=/tmp/%u } # Mail filter configuration mail_plugins = $mail_plugins mail_filter plugin { mail_filter = mail-filter read %u mail_filter_out = mail-filter write %u } service mail-filter { executable = script /usr/local/bin/mail-filter.sh user = dovecot unix_listener mail-filter { mode = 0666 } } And create the example script in /usr/local/bin/mail-filter.sh with executable permissions: #!/bin/bash echo "arguments were: $@" 1>&2 tempfile=$(mktemp) cat > "${tempfile}" cat "${tempfile}" rm "${tempfile}" This script simply logs the arguments it recieves, writes stdin to a file then retrieves it again from the file. Here's a sample session of me using dovecot-lda to pass a message through this script, then retrieve it again with doveadm: root@scratch-b6fd8bdd:~# /usr/lib/dovecot/dovecot-lda -d fincham@scratch-b6fd8bdd -f 'Test <scratch-b6fd8bdd>' < /root/test.eml root@scratch-b6fd8bdd:~# doveadm fetch -u 'fincham@scratch-b6fd8bdd' hdr subject Test hdr: To: Test <fincham@scratch-b6fd8bdd> From: Test <fincham@scratch-b6fd8bdd> Subject: This is the test e-mail root@scratch-b6fd8bdd:~# tail /var/log/syslog | grep mail-filter Sep 5 00:07:48 scratch-b6fd8bdd dovecot: mail-filter: Error: arguments were: write fincham@scratch-b6fd8bdd Sep 5 00:07:50 scratch-b6fd8bdd dovecot: mail-filter: Error: arguments were: read fincham@scratch-b6fd8bdd However after upgrading dovecot to the buster version this process no longer works, and the logged argv of the example script is very strange: root@scratch-b6fd8bdd:~# apt dist-upgrade Reading package lists...

Hello, after migrating from self-compiled Dovecot 2.3.3 to Dovecot 2.3.8 from the repository (Ubuntu 18.04 LTS "Bionic" packages) I have issues with the submission service. If I send an email, it will not be forwarded and I get the following error message: Oct 11 09:29:01 srv2 dovecot: submission(hativ(a)example.com)<15819><XFnL eJ2U0rgqAoEMwMAIoDQqhHgB7k+O>: Panic: file smtp-client-connection.c: line 1212 (smtp_client_connection_established): assertion failed: (!conn->connect_succeeded) Oct 11 09:29:01 srv2 dovecot: submission(hativ(a)example.com)<15819><XFnL eJ2U0rgqAoEMwMAIoDQqhHgB7k+O>: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0xe7f7e) [0x7f64b1f76f7e] -> /usr/lib/dovecot/libdovecot.so.0(+0xe8021) [0x7f64b1f77021] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f64b1ecfaf4] -> /usr/lib/dovecot/libdovecot.so.0(+0x50ec8) [0x7f64b1edfec8] -> /usr/lib/dovecot/libdovecot.so.0(+0x51078) [0x7f64b1ee0078] -> /usr/lib/dovecot/libdovecot.so.0(+0x541f4) [0x7f64b1ee31f4] -> /usr/lib/dovecot/libdovecot.so.0(smtp_client_command_input_reply+0x1f8) [0x7f64b1edb738] -> /usr/lib/dovecot/libdovecot.so.0(+0x54a93) [0x7f64b1ee3a93] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x6f) [0x7f64b1f909af] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x13c) [0x7f64b1f9237c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x4c) [0x7f64b1f90abc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f64b1f90cd8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f64b1eff053] -> dovecot/submission [hativ(a)example.com fec0:810c:c0c0:8a0:342a:8478:1ee:4f8e GREETING](main+0x3d1) [0x55dcc748fec1] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xe7) [0x7f64b1abfb97] -> dovecot/submission [hativ(a)example.com fec0:810c:c0c0:8a0:342a:8478:1ee:4f8e GREETING](_start+0x2a) [0x55dcc749009a] Does somebody has any idea?

When I use fs:posix as dict for acl_shared_dict, like in Dovecot wiki (https://wiki.dovecot.org/SharedMailboxes/ClusterSetup) doveadm-server crash with error: # doveadm acl set -u USERNAME FOLDER user=DEST_USERNAME lookup read write-seen doveadm(USERNAME): Panic: file dict-fs.c: line 127 (fs_dict_iterate_init): assertion failed: ((flags & DICT_ITERATE_FLAG_RECURSE) == 0) doveadm(USERNAME): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9f3de) [0x7f0e4a4b23de] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f0e4a4b244a] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f0e4a44377c] -> /usr/lib64/dovecot/libdovecot.so.0(+0x31688) [0x7f0e4a444688] -> /usr/lib64/dovecot/libdovecot.so.0(dict_iterate_init_multiple+0x4d) [0x7f0e4a47cadd] -> /usr/lib64/dovecot/libdovecot.so.0(dict_iterate_init+0x29) [0x7f0e4a47cb89] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_lookup_dict_rebuild+0x3e1) [0x7f0e49a40371] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_acllist_rebuild+0x488) [0x7f0e49a3dd18] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_object_update+0x3c7) [0x7f0e49a3e867] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_mailbox_update_acl+0x68) [0x7f0e49a41e28] -> /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so(+0x2c11) [0x7f0e48da1c11] -> /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so(+0x3060) [0x7f0e48da2060] -> doveadm(+0x2b41c) [0x556f1280b41c] -> doveadm(+0x2c01a) [0x556f1280c01a] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x23b) [0x556f1280ce7b] -> doveadm(doveadm_cmd_run_ver2+0x50c) [0x556f1281c73c] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x556f1281c7d7] -> doveadm(main+0x1e4) [0x556f127fb944] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f0e4a071c05] -> doveadm(+0x1bd35) [0x556f127fbd35] Aborted Attached coredump and configuration. I'm not a programmer, but seems that assert is raised by 'fs_dict_iterate_init' function inside 'src/lib-dict-extra/dict-fs.c': static struct dict_iterate_context * fs_dict_iterate_init(struct dict *_dict, const char *const *paths, enum dict_iterate_flags flags) { ... /* these flags are not supported for now */ i_assert((flags & DICT_ITERATE_FLAG_RECURSE) == 0); ... because it is called by 'acl_lookup_dict_iterate_read' function in file 'src/plugins/acl/acl-lookup-dict.c' static void acl_lookup_dict_iterate_read(struct acl_lookup_dict_iter *iter) { ... dict_iter = dict_iterate_init(iter->dict->dict, prefix, DICT_ITERATE_FLAG_RECURSE); ... with DICT_ITERATE_FLAG_RECURSE set. Same problem also with Dovecot 2.3.0. Thanks, Marco -- Marco Giunta - ITCS SysAdmin Via Bonomea, 265 34136 - Trieste, Italy Tel: +39-040-3787-503 Fax: +39-040-3787-244
