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 ? I suspect that to increase the space for the specific user AZT000, that should be : quota_rule=azt000:storage=160gb.. but where Thanks and regards, Le 06/10/2021 à 15:49, Stephane Magnier a écrit : > not exactly.. > > Usernames are : azt000, azt001, azt002, etc..... > All of them have their mailbox in /var/spool2/mail/azt000, > /var/spool2/mail/azt001 ) > > Everybody will get 30Gb by default > Except the user *azt000*, who will have 160Gb > > So, I understand, that the general rule is this > > > plugin { > quota = maildir:User quota > quota_rule = *:storage=30GB > quota_rule2 = Trash:storage=+100MB > quota_rule3 = Spam:storage=+20%% > } > > > Now, I suppose , to specify the user *azt000 and only this one*, to > get a quota of 160Gb, I should write something like: > *quota_rule=azt000:storage=+160Gb *correct ?* > * > but where ! > > 1) If I had this sentence into_the plugin_ ( as it was before ) , it's > not considered.

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.

Issue with the log service after upgrading from 2.1.17 to 2.3.10.1
by Grant Keller 05 Oct '21

05 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.

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?

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

04 Oct '21

Hello, Upfront note: I know very little about dovecot and IMAP lingo / terms of art, I'll try to be clear and complete but I may be missing important bits. I have a VPS backup with mailboxes in the maildir dovecot format: $ ls some/folder/backup/mail/domain/\* cur dovecot-uidlist dovecot-uidvalidity.5c0637b7 dovecot.index.cache dovecot.mailbox.log subscriptions dovecot-keywords dovecot-uidvalidity dovecot.index dovecot.index.log new tmp Separately and independently, I also have an existing IMAP account I do not personally manage. By "account" I mean that if I connect to the IMAP server, LOGIN, then LIST I see a pretty standard set of folders: (\HasNoChildren) "/" INBOX (\HasNoChildren \Archive) "/" Archive (\HasNoChildren \Drafts) "/" Drafts (\HasNoChildren \XNotes) "/" Notes (\HasNoChildren \Sent) "/" Sent (\HasNoChildren \Junk) "/" Spam (\HasNoChildren \Trash) "/" Trash I would like to copy / upload / … the content of the backup mailboxes to the IMAP account, ideally without losing the metadata. I asked about this on IRC and user "cmouse" provided me with information about the imapc storage (plugin?), a sample "doveadmin import" command, and a sample dovecot configuration which I expanded to this (for simplicity, the original sample command used a lot of `-c` and I figured I could just shove them into the configuration file for readability): $ dovecot -n # 2.3.16 (): /opt/local/etc/dovecot/dovecot.conf # OS: Darwin 15.6.0 x86_64 auth_verbose = yes imapc_host = <server> imapc_password = # hidden, use -P to show it imapc_port = 993 imapc_ssl = imaps imapc_user = <user> mail_location = imapc: # did not setup a "vmail" user or group as I just want to move the contents mail_uid = <current_user> mail_gid = staff namespace { inbox = yes location = prefix = separator = / } ssl = no verbose_proctitle = yes verbose_ssl = yes That did not work as I guess "import" wants to create all the mailboxes, and these already exist: $ doveadm -Dv import maildir:some/folder/backup/mail/domain/\* '.' all […] Debug: Mailbox Archive: Mailbox opened because: import Debug: Mailbox spam: Mailbox opened because: import Debug: Mailbox Junk: Mailbox opened because: import Debug: Mailbox Trash: Mailbox opened because: import Debug: Mailbox Sent: Mailbox opened because: import Debug: Mailbox Drafts: Mailbox opened because: import Debug: Mailbox INBOX.Spam: Mailbox opened because: import Debug: Mailbox INBOX.Junk: Mailbox opened because: import Debug: Mailbox INBOX.Drafts: Mailbox opened because: import Debug: Mailbox INBOX: Mailbox opened because: import Debug: Namespace : Using permissions from : mode=0700 gid=default Error: Couldn't create mailbox ./INBOX: Mailbox already exists I tried messing around with the options but didn't achieve anything, the only change which did anything visible was to replace '.' with '.INBOX' which resulted in import creating `.IMPORT/IMPORT` and exiting with: Error: Couldn't create mailbox INBOX/INBOX: Invalid mailbox name which… fair enough.

Something like that? Anyway that's where I'm stuck so far, I've got no idea whether `sync` is even the right direction but I don't really know what to try. NOTES: the maildir I'm working on right now has 41 messages in it: $ ls some/folder/backup/mail/domain/\*/cur | wc -l 41 though the uidlist has 45 lines (which is 3 more than I'd have expected): $ wc -l some/folder/backup/mail/domain/\*/dovecot-uidlist 45 some/folder/backup/mail/domain/\*/dovecot-uidlist Xavier

ssl_cipher_list
by dovecot＠ptld.com 04 Oct '21

04 Oct '21

Is there a difference between not setting #ssl_cipher_list = or setting to nothing ssl_cipher_list = or setting to ssl_cipher_list = PROFILE=SYSTEM Which is the best preferred way for default? Also, the docs say "You should usually prefer server ciphers and their order, so setting ssl_prefer_server_ciphers=yes is recommended." however this setting is =no by default. Why? Should it be yes or not?
