quota clone + mysql + duplicate key
by Dimos Alevizos 05 Jun '17

05 Jun '17

I'm trying to setup quota clone with mysql on dovecot 2.2.29.1. I see in the wiki that the table is always updated to the new value (https://wiki.dovecot.org/Plugins/QuotaClone) : > Every time quota is updated, the value is updated to the cloned dict. > There are race conditions with it so the quota may not always be 100% > correct. The old value is always replaced with the new one though (not > just incremented/decremented) so the cloned quota is never too much wrong. But the queries I see don't agree : 1186029 Query BEGIN 1186029 Query INSERT INTO quota (bytes,messages,username) VALUES (25002030,226,'user(a)domain.tld') ON DUPLICATE KEY UPDATE bytes=bytes+25002030,messages=messages+226 1186029 Query COMMIT Is it a bug or am I missing something in my configuration ? The relevant part of the config : dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } plugin { quota = count:User quota quota_clone_dict = proxy::sqlquota quota_exceeded_message = Quota for this mail account has been exceeded, please try again later. quota_grace = 1M quota_vsizes = yes } map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Dimos

ACL File
by Bobber 02 Jun '17

02 Jun '17

I'm getting inconsistent behavior from my acl file. I have an acl vfile configured with this: > Jobs$* anyone lrwikst > $* user=bob.wooldridge(a)edm-inc.com lrwstipekxa > $* user=michael.user(a)edm-inc.com lrwstipekxa > Jobs$* user=bob.wooldridge(a)edm-inc.com lrwstipekxa > Jobs$* user=michael.user(a)edm-inc.com lrwstipekxa The Jobs folder is a public shared folder. I want just the two users to be able to have complete control of anything in the shared Jobs folder. Currently, user bob is able to move folders to sub folders but user michael is sometimes able to move folders but mostly not. I am using Thunderbird as the mail client. Sometimes I can restart Thunderbird and it will allow one operation but subsequent operations error out with Thunderbird saying the user does not have permissions. Here's my doveconf -n: > # 2.2.30.1 (eebd877): /usr/local/etc/dovecot/dovecot.conf > # OS: Linux 3.16.0-0.bpo.4-amd64 x86_64 Debian 7.11 > auth_cache_size = 8 k > auth_debug = yes > first_valid_gid = 89 > first_valid_uid = 89 > last_valid_gid = 89 > last_valid_uid = 89 > listen = * > log_path = /dev/stderr > login_greeting = IMAP service for edm-inc.com clients. > mail_location = maildir:~/Maildir > mail_plugins = " listescape acl" > namespace { > inbox = yes > location = > prefix = > separator = $ > type = private > } > namespace { > location = maildir:/home/vpopmail/domains/edm-inc.com/public > prefix = Jobs$ > separator = $ > subscriptions = no > type = public > } > passdb { > args = cache_key=%u%s > driver = vpopmail > } > plugin { > acl = vfile:/usr/local/etc/dovecot/acls:cache_secs=300 > } > protocols = imap > service auth { > user = root > vsz_limit = 64 M > } > service imap-login { > process_limit = 150 > service_count = 1 > } > ssl_cert = </etc/ssl/certs/mail_edm-inc_com.pem > ssl_key = # hidden, use -P to show it > userdb { > driver = vpopmail > } > userdb { > driver = vpopmail > } > protocol imap { > mail_plugins = " listescape acl imap_acl" > } -- *Bob Wooldridge* Blog: http://kc0dxf.net/blog/

updated to dove 2.30.1 and still the same error ....
by dovecot＠jeffandjessi.com 02 Jun '17

02 Jun '17

Well.. updated to 2.30.1 hoping it would fix this mysterious seg fault ... ,but nope ... auth: Fatal: master: service(auth): child 14502 killed with signal 11 (core dumped) the core dump shows gdb) bt #0 0x00007f7ff4a06bee in ?? () #1 0x00007f7ff74a4f44 in io_loop_handle_remove () from /usr/local/lib/dovecot/libdovecot.so.0 #2 0x00007f7ff74a3765 in io_remove_full () from /usr/local/lib/dovecot/libdovecot.so.0 #3 0x00007f7ff7438b62 in master_service_deinit () from /usr/local/lib/dovecot/libdovecot.so.0 #4 0x00000000004307ef in main () no symbols are available as this is a pkg install.... so whats next? time to dump dovecot after running it for 10 years? Can't believe no one else is seeing this .... the symtoms are dovecot starts up fine when a client connects, they authorize just fine and download email .... about a minute later the auth process crashes and the entire process starts over .... so how do you trouble shoot this ... it sounds like a coding issue some place .... anyone ?

Re: Retrieving mail from read-only mdbox

> I've tried using IMAP with mail_location pointed at the snapshot, but, > though I can get a listing of emails in the mailbox, the fetch fails when > dovecot can't write-lock dovecot.index.log. I've thought about doing this someday (adding snapshots to a user's namespace) but never got around to doing it. Snapshots get rotated (e.g. hourly.1 -> hourly.2 -> etc.) so every hour, so any indices produced gets invalidated. You would need to generate MEMORY indices to create it on the fly. Something like namespace snapshots { location = ...:INDEX==MEMORY ... } I'm not sure how dovecot would react when NetApp pulls the rug out from under one of the hourly snapshots and replace it with the next hour's version.

SSL problem - no banner

Hi, I am running dovecot 2.2.22-1ubuntu2.4 on a ubuntu 16.04 server. It has a valid Letsencrypt certificate but the problem also happens with a self-digned one.

Two domains, same users
by Sandbox 01 Jun '17

01 Jun '17

Hi, I have two LDAP domains, which has some equal users, eg: abc(a)domain1.com abc(a)domain2.com I sat up this config: domain1 users maildirs are stored in /home/vmail/username domain2 users maildirs are stored in /home/vmail/domain2/username This works fine except one thing: i cant set up the ldap query to choose the correct maildir if the user names are equal. Is it possible to use a user_filter which will choose the correct maildir and user/domain from the email address? My current ldap.conf for domain1: hosts = ldap.domain1.com base = ou=People,dc=domain1,dc=com ldap_version = 3 user_attrs = uid=user user_filter = (uid=%n) pass_attrs = uid=user,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 and for domain2: hosts = ldap.domain2.com base = ou=People,dc=domain2,dc=com ldap_version = 3 user_attrs = \ =mail=maildir:/home/vmail/%{ldap:departmentNumber)/%n/Maildir user_filter = (uid=%n) pass_attrs = uid=%n,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 Thanks, Robert

sieve folders in maildir with imap: not a directory not fixed with maildir_stat_dirs = yes
by David Gessel 01 Jun '17

01 Jun '17

As my logs fill up with "imap(user(a)domain.com): Error: stat(/mail/doman.com/user//.dovecot.sieve/tmp) failed: Not a directory" errors, I followed the advice at https://wiki2.dovecot.org/VirtualUsers/Home and https://dovecot.org/list/dovecot/2016-June/104403.html and set in /usr/local/etc/dovecot/conf.d/10-mail.conf # By default LIST command returns all entries in maildir beginning with a dot. # Enabling this option makes Dovecot return only entries which are directories. # This is done by stat()ing each entry, so it causes more disk I/O. # (For systems setting struct dirent->d_type, this check is free and it's # done always regardless of this setting) maildir_stat_dirs = yes My mailbox format reads "mail_location = maildir:~:CONTROL=/var/no-quota/%u:INDEX=MEMORY" The error is factually correct, but there is not .dovecot.sieve/tmp directory or file as .dovecot.sieve is a file (the head sieve script that calls the subordinate scripts out of the /sieve directory. There is a tmp directory at /sieve/tmp/ drwxr----- 2 vmail vmail 2B May 31 04:14 tmp Any hints as to why this isn't working? It does seem like the right answer.
