SNI via lookup?
by Felipe Gasper 08 Oct '21

08 Oct '21

Hello, How (if at all) might I configure a Dovecot server to read its SNI configuration dynamically? Right now I’ve got thousands of domains all served from a quite-large static config file that has to be rebuilt every time a domain is added or removed. It would be much simpler if there were a way to make Dovecot call out to some external service to fetch a given domain’s certificate. Thank you in advance! cheers, -Felipe Gasper

writing Maildir subscriptions file outside of dovecot
by David Mandelberg 07 Oct '21

07 Oct '21

Hi, Is it safe to write to the Maildir subscriptions file directly? I'm trying to figure out a way to make sure the subscriptions match the actual folders exactly. I know how to subscribe to existing mailboxes with `doveadm mailbox list` and `doveadm mailbox subscribe`, but the latter seems to only accept mailboxes on the command line, and any local user can see the command line of any other user's commands. Also, that doesn't handle unsubscribing from non-existent mailboxes. I think unsubscribing from any mailboxes listed in `doveadm mailbox list -s` but not in `doveadm mailbox list` would work, but it has the same issue of mailboxes on the command line. It looks like I could do what I want with something like this command, but I'm not sure if it's safe to write directly to the subscriptions file: { echo INBOX; ls -1A | grep '^\.' | cut -c 2-; } > subscriptions (I was also thinking about using `doveadm mailbox list` to write the subscriptions file directly, but it looks like they use different separators and encodings.)

reconsidering my (your?) current setup
by Marc 07 Oct '21

07 Oct '21

With redhat 'dumping' the support for centos and the availability of containers. I thought about reconsidering my default dovecot setup. Since the concept of having a lts distribution that is supported by redhat/centos is more or less 'unavailable'. I thought about using the repo of dovecot with centos8stream. os == For now I stick with centos8stream, just because the rest is still on centos7 support and the ceph development team is using it as a default. (And can't yet let go of the idea this closest to professional distro ;)) auth uid gid os =============== I am not really convinced that storing users in mysql/postgres is a better alternative than having linux do auth. I also think it is good to have mailbox files stored with different uid's (no idea if this is even the case when dovecot is using mysql/maria/postgres) Normally I would use a synced ldap server on the vm for authentication. But I was thinking of using now an external ldap task from the container environment. To de-duplicate services/data and make the environment simple. Since rh is moving to a different ldap server, it would be good to have this seperated in the future. New to me is the sssd, used nscd/nslcd for decades without issues. I guess the best solution is to have the os uid/gid coming from sssd, configure sssd to have a huge timeout if the backend ldap auth is not available. What is your thought about this? auth uid gid dovecot ==================== I do not really have an idea if I should have dovecot use ldap directly or use this sssd pam? The advantage of using ldap directly is you could maybe skip identifying users in the os. But maybe then tools like dovadm that require a user are not working anymore. From the keep it simple perspective it is probably better to use sssd. However centos8stream and sssd are not really known to me. So any ideas/advice about this?

strange cache behavior

Hi I Migrate user from ldap to mysql (director+nodes) (2.2.36.4) All works fine but when I turn on debbug auth I get "cache differences " look: dovecot6 (lmysql)run: #doveadm user mx8(a)domain.ltd field value user domain.ltd_mx8 uid 300 gid 300 home /vmail2/na/domain.ltd_mx8 mail maildir:~/Maildir:INDEX=/var/dovecot_indexes/vmail2/na/domain.ltd_mx8 quota_rule *:bytes=10485760 In second time (via cache) I get: #doveadm user mx8(a)domain.ltd field value uid 300 gid 300 home /vmail2/na/domain.ltd_mx8 mail maildir:~/Maildir:INDEX=/var/dovecot_indexes/vmail2/na/domain.ltd_mx8 quota_rule *:bytes=10485760 cache not give me "user domain.ltd_mx8" value In ldap every time I get this same I try debbug and i found difference in 2 and 3 line: mysql: Oct 7 16:42:04 dovecot6 dovecot: auth: Debug: master in: USER#0111#011mx8(a)domain.ltd#011service=doveadm#011debug Oct 7 16:42:04 dovecot6 dovecot: auth: Debug: sql(mx8(a)natan-test.iq.pl): userdb cache hit: home=/vmail2/na/domain.ltd_mx8#011quota_rule=*:bytes=10485760 Oct 7 16:42:04 dovecot6 dovecot: auth: Debug: userdb out: USER#0111#011mx8@domain.ltd#011home=/vmail2/na/natan-test.iq.pl_mx8_natan-test#011quota_rule=*:bytes=10485760 in ldap: Oct 7 16:45:31 dovecot5 dovecot: auth: Debug: master in: USER#0111#011mx8(a)domain.ltd#011service=doveadm#011debug Oct 7 16:45:31 dovecot5 dovecot: auth: Debug: ldap(mx8(a)natan-test.iq.pl): userdb cache hit: home=/vmail2/na/domain.ltd_mx8#011quota_rule=*:bytes=10485760#011user=domain.ltd_mx8 Oct 7 16:45:31 dovecot5 dovecot: auth: Debug: ldap(mx8(a)natan-test.iq.pl): username changed mx8(a)domain.ltd-> domain.ltd_mx8 Oct 7 16:45:31 dovecot5 dovecot: auth: Debug: userdb out: USER#0111#011domain.ltd_mx8#011home=/vmail2/na/natan-test.iq.pl_mx8_natan-test#011quota_rule=*:bytes=10485760 first query witchout cache: ldap Oct 7 16:45:21 dovecot5 dovecot: auth: Debug: userdb out: USER#0111#011domain.ltd_mx8#011home=/vmail2/na/domain.ltd_mx8#011quota_rule=*:bytes=10485760 mysql Oct 7 16:41:34 dovecot6 dovecot: auth: Debug: userdb out: USER#0111#011domain.ltd_mx8#011home=/vmail2/na/domain.ltd_mx8#011quota_rule=*:bytes=10485760 And I dont known where is a problem ? maybe in the cache setting ?

Hi, sorry to bother you.. any idea ? how to give more space to a specific user ? And where to place the line, in order to overide the general rule ?

Quota emails... nothing happened
by Stephane Magnier 06 Oct '21

06 Oct '21

sieve: active= doesn't seem to use bindir=
by David Mandelberg 05 Oct '21

05 Oct '21

Hi, I'm trying to set up dovecot to read sieve source files from a read-only directory, and save compiled binaries to a separate directory with the bindir option. That worked when I pointed the sieve option at a single file, but I just changed it to point at a directory and added the active= option, also pointing at a symlink in a read-only directory. It looks like dovecot is trying to save the compiled active script to the same directory as the source file, instead of to bindir. Am I missing something? $ doveconf -n # 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.13 (cdd19fe3) # OS: Linux 5.10.0-8-amd64 x86_64 Debian 11.0 ext4 ... plugin { sieve = file:/usr/local/etc/mail/%{domain}/%{username}/sieve;active=/usr/local/etc/mail/%{domain}/%{username}/sieve/.active.sieve;bindir=/var/cache/mail/%{domain}/%{username}/sieve sieve_before = file:/etc/dovecot/sieve-before sieve_filter_bin_dir = /etc/dovecot/sieve-filter-bin sieve_filter_exec_timeout = 30s sieve_global_extensions = +vnd.dovecot.filter sieve_plugins = sieve_extprograms sieve_user_log = /var/local/mail/persistent/mail/%{domain}/%{username}/sieve.log } ...

Issue with the log service after upgrading from 2.1.17 to 2.3.10.1
by Grant Keller 04 Oct '21

04 Oct '21

Hello, As stated in the subject we have been doing a pretty big version upgrade. Both new and old are on CentOS 7. For the second time, one of our upgraded servers have had the dovecot log process start consuming 100% cpu, and the strace output shows it trying to access /etc/localtime: stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 With no other output then that multiple times a second. The process itself shows this from ps: root 76106 8.3 0.0 15384 6532 ? R Sep29 140:21 dovecot/log [service too fast: 34/34/imap-postlogin: ] As a part of this upgrade we also modified our postlogin script to include an index location for each user, so I am not sure if this is related to that change or a change in the logging service.

Re: Re: Exporting a mailbox over IMAP.
by Xavier Morel 04 Oct '21

04 Oct '21

I'd seen them around yes, but that would require mounting a local dovecot to make the mailboxes available over IMAP no? And I was kinda hoping to avoid doing that, as as noted in the initial message I know very little about dovecot.

I've seen thread with problem identical to mine started "Fri May 28 13:54:27 EEST 2021" and I was wondering did you get to fix this issue? Mine looks like this: dovecot: replicator: Panic: data stack: Out of memory when allocating 1073741864 bytes dovecot: replicator: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7f57c5a4c4e2] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f57c5a4c5fe] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc49b) [0x7f57c5a5849b] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc531) [0x7f57c5a58531] -> /usr/lib/dovecot/libdovecot.so.0(+0x53aee) [0x7f57c59afaee] -> /usr/lib/dovecot/libdovecot.so.0(+0x53435) [0x7f57c59af435] -> /usr/lib/dovecot/libdovecot.so.0(+0xf5d88) [0x7f57c5a51d88] -> /usr/lib/dovecot/libdovecot.so.0(+0x11b818) [0x7f57c5a77818] -> /usr/lib/dovecot/libdovecot.so.0(+0xf25f2) [0x7f57c5a4e5f2] -> /usr/lib/dovecot/libdovecot.so.0(+0xf26a9) [0x7f57c5a4e6a9] -> /usr/lib/dovecot/libdovecot.so.0(buffer_write+0x1e) [0x7f57c5a4e8be] -> dovecot/replicator(replicator_queue_push+0x14a) [0x55aabc673b1a] -> dovecot/replicator(+0x5296) [0x55aabc673296] -> dovecot/replicator(+0x493e) [0x55aabc67293e] -> dovecot/replicator(+0x4acc) [0x55aabc672acc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x69) [0x7f57c5a6df59] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x132) [0x7f57c5a6f592] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x50) [0x7f57c5a6e000] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7f57c5a6e1c0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f57c59e44e3] -> dovecot/replicator(main+0x18d) [0x55aabc671cad] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7f57c57b4d0a] -> dovecot/replicator(_start+0x2a) [0x55aabc671d6a] And setting vsz_limit = 0 doesn't help either - it just tries to allocate all available memory.
