slow mailbox refreshes
by Fabian A. Santiago 09 Jul '18

09 Jul '18

Hello, I am using dovecot 2.3.2 on my private email server in conjunction with: centos 7.5 apache 2.4.6 mariadb 10.2.16 roundcube mail 1.3.6 php 5.6.36 postfix 2.10.1 I have one mailbox with nearly 30k messages in it dispersed across several folders. it's often very slow in refreshing the message list, especially in the one largest 25k+ message folder. is this simply to be expected based on my message count or is there some kind of performance optimization and tuning i can do to improve the response times? The mail server itself is a linode hosted VPS: intel xeon e5-2680 v2 @ 2.80 GHz, 4 cores 8 GB real memory 2 GB virtual memory 200 GB local storage (ext4) KVM hypervisor Thanks everyone for any guidance you can offer. -- Fabian S.

FreeBSD 11.1 / amd64 dovecot --version 2.3.2 (582970113) Pigeonhole version 0.5.2 (7704de5e) I have run 'sieve-test" many times to check out changes in my "sieve" scripts.

Re: Question about password field in passwd-file

See https://wiki.dovecot.org/PasswordDatabase/ExtraFields > > > --- > Aki Tuomi > Dovecot oy Hi Aki, Thank you for your reply. I have two questions regarding this: 1. Is the “nopassword” attribute the same as specifying a null password field by itself ? The documentation at [1] seems to suggest that having a null password AND specifying “nopassword” will allow someone to authenticate with _no_ password: “nopasword: if you want to allow all passwords, use an empty password and this field.” Farther down, the page seems to indicate that the “nologin” attribute is what I am looking for: “nologin: User isn’t actually allowed to log in even if the password matches . . .” Or possibly “noauthenticate”: “noauthenticate: Do not perform any authentication . . ." 2. Is “nologin” functionally equivalent to specifying no password in the password field ? I am assuming that setting a null password (even without “nologin”), prevents login with ANY or NO password as a blank field would default to a {CRYPT} scheme and a call to crypt() cannot return a null string. As background to why I want to do this, I have a server with a basic Dovecot setup that provides SMTP SASL AUTH, IMAP and LMTP for Postfix. For the passdb and userdb, I use the same passwd-style file: /etc/dovecot/dovecot.conf userdb { driver = passwd-file args = /etc/dovecot/passwd } passdb { driver = passwd-file args = /etc/dovecot/passwd } I use usernames for SMTP SASL AUTH and IMAP that differ from either: user(a)example.com or user. So for one user, for example, I have: /etc/dovecot/passwd # SMTP SASL AUTH and IMAP user accounts and passwords user_account_1:{PLAIN}password: . . . # LMTP username/e-mail address user(a)example.com:: . . . :/var/mail/vhosts/example.com/user_account_1 So in the LMTP entry I specify no password between the colons to prevent someone trying to logon via IMAP using the LMTP username/e-mail address. Is this correct and: is there a better way to do this ? Thanks, - J Sources: [1] https://wiki.dovecot.org/PasswordDatabase/ExtraFields

Get rid of the "dbox-Mails"-folder

Hey to all, is it possible to get rid of the "dbox-Mails"-folder when using sdbox? Currently my folder structure looks like this (I hope the output from tree would be formatted well): /srv/mail/ └── example.com └── user ├── dovecot-acl-list ├── dovecot-attributes ├── dovecot.list.index.log ├── dovecot.mailbox.log ├── dovecot-uidvalidity ├── dovecot-uidvalidity.5b3f746f ├── mailboxes │ ├── Drafts │ │ └── dbox-Mails │ │ └── dovecot.index.log │ ├── INBOX │ │ └── dbox-Mails │ │ ├── dovecot.index.cache │ │ ├── dovecot.index.log │ │ └── u.1 │ ├── Junk │ │ └── dbox-Mails │ │ └── dovecot.index.log │ ├── Sent │ │ └── dbox-Mails │ │ └── dovecot.index.log │ └── Trash │ └── dbox-Mails │ └── dovecot.index.log └── subscriptions I would like to let it look like this: /srv/mail/ └── example.com └── user ├── dovecot-acl-list ├── dovecot-attributes ├── dovecot.list.index.log ├── dovecot.mailbox.log ├── dovecot-uidvalidity ├── dovecot-uidvalidity.5b3f746f ├── mailboxes │ ├── Drafts │ │ └── dovecot.index.log │ ├── INBOX │ │ └── dovecot.index.cache │ │ └── dovecot.index.log │ │ └── u.1 │ ├── Junk │ │ └──dovecot.index.log │ ├── Sent │ │ └── dovecot.index.log │ └── Trash │ └── dovecot.index.log └── subscriptions My path configuration: mail_attribute_dict = file:%h/dovecot-attributes mail_home = /srv/mail/%d/%n/ mail_location = sdbox:~/ I have tried mail_location = sdbox:~/:FULLDIRNAME= and mail_location = sdbox:~/:FULLDIRNAME=/ but it doesn't work. The first doesn't change anything. The second auto-creates the folders after first login like I want, but after next login they are greyed out and no longer accessible. Is it possible to get rid of the "dbox-Mails"-folder? I want this because I don't like to have an unneeded deep folder structure. Or is there a good reason to let the "dbox-Mails" folder in my setup?

Question about password field in passwd-file
by J Doe 07 Jul '18

07 Jul '18

Hello, I have a question regarding the password field of the passwd-file [1]. According to the wiki, the password field assumes a {SCHEME} of CRYPT when the {SCHEME} is not prefixed to this field. So, a passwd-file like: user:password: . . . … is equivalent to: user:{CRYPT}password: . . . Does that mean an example passwd-file with NEITHER {SCHEME} or password, like: user(a)example.com:: . . . (note no scheme or password specified between colons) …means that the user(a)example.com user does not have any valid crypted password and therefore the user(a)example.com user cannot be authenticated ? For example, if I use doveadm to create a null CRYPT password: $ sudo doveadm pw -s CRYPT -p “” -u user(a)example.com … gives the result: {CRYPT}txR1JRq9140Qk … which differs from the example password field having NEITHER {SCHEME} or password, like: user(a)example.com:: . . . … so if I attempt to logon using a null password for user(a)example.com when nothing is specified in the password field for the passwd-file: /etc/dovecot/passwd user(a)example.com:: . . . $ sudo doveadm auth test user(a)example.com password: passdb: user(a)example.com auth failed … it is impossible to logon as user(a)example.com with ANY PASSWORD and/or a NULL password ? Thanks, - J Sources: [1] https://wiki2.dovecot.org/AuthDatabase/PasswdFile

Hello, does dovecot support bcrypt $2y$ version? (BLF-CRYPT - Blowfish crypt) doveadm pw -s BLF-CRYPT generates a {BLF-CRYPT}$2a$05$....... password. Does this mean that dovecote will not authenticate against a $2y$10$....... password? Thanks in advance, -Graham-

Hey guys, Has anybody ever used imaptest to benchmark *ONLY* reads? I'm trying to run a battery of tests in my new cluster and apparently no combination of parameters works, because fetch instruction doesn't run.

user/password Authentication via Joomla database
by Graham S. Jarvis 05 Jul '18

05 Jul '18

Hello, did anyone ever set up Authentication via lookups to a Joomla (mysql) database? What I'd like to do is lookup Joomla users (who are in specific/multiple groups) in the Joomla database and then fallback to /etc/passwd authentication to let system users authenticate. I'm running : # 2.2.35 (b1cb664): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 11.1-RELEASE-p10 amd64 Thanks in advance, -Graham-

v2.3.2 released
by Timo Sirainen 04 Jul '18

04 Jul '18

https://dovecot.org/releases/2.3/dovecot-2.3.2.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.2.tar.gz.sig v2.3.2 is mainly a bugfix release. It contains all the changes in v2.2.36, as well as a bunch of other fixes (mainly for v2.3-only bugs). Binary packages are already in https://repo.dovecot.org/ * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. + cassandra: Use fallback_consistency on more types of errors + lmtp proxy: Support outgoing SSL/TLS connections + lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings. + submission: Add support for rawlog_dir + submission: Add submission_client_workarounds setting. + lua auth: Add password_verify() function and additional fields in auth request. - doveadm-server: TCP connections are hanging when there is a lot of network output. This especially caused hangs in dsync-replication. - Using multiple type=shared mdbox namespaces crashed - mail_fsync setting was ignored. It was always set to "optimized". - lua auth: Fix potential crash at deinit - SSL/TLS servers may have crashed if client disconnected during handshake. - SSL/TLS servers: Don't send extraneous certificates to client when alt certs are used. - lda, lmtp: Return-Path header without '<' may have assert-crashed. - lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash - lda: -f parameter didn't allow empty/null/domainless address - lmtp, submission: Message size limit was hardcoded to 40 MB. Exceeding it caused the connection to get dropped during transfer. - lmtp: Fix potential crash when delivery fails at DATA stage - lmtp: login_greeting setting was ignored - Fix to work with OpenSSL v1.0.2f - systemd unit restrictions were too strict by default - Fix potential crashes when a lot of log output was produced - SMTP client may have assert-crashed when sending mail - IMAP COMPRESS: Send "end of compression" marker when disconnecting. - cassandra: Fix consistency=quorum to work - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: Fixes to indexing mails via virtual mailboxes. - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.

Released Pigeonhole v0.5.2 for Dovecot v2.3.2.
by Stephan Bosch 04 Jul '18

04 Jul '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.2. You will need this release for Dovecot v2.3.2, because the previous v0.5.1 release will not work. No changes were performed since the release candidate. Much like version 0.4.24 for Dovecot v2.2, this release consists mostly of fixes that accumulated over the last few months. Beyond that, this release contains the new IMAP FILTER=SIEVE capability, which was also released earlier with 2.2.24 (with a few additional fixes). Changelog v0.5.2: + Implement plugin for the a vendor-defined IMAP capability called "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering in IMAP. More information can be found in doc/plugins/imap_filter_sieve.txt. - The Sieve address test caused an assertion panic for invalid addresses with UTF-8 codepoints in the localpart. Fixed by properly detecting invalid addresses with UTF-8 codepoints in the localpart and skipping these like other invalid addresses while iterating addresses for the address test. - Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters. - Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field. - Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost. - Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.2.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.2.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

force-resync and replication
by Hanspeter Kunz 02 Jul '18

02 Jul '18

Hi list, I am using dovecot 2.2.27 (c0f36b0) on two servers with (dovecot) replication between them. I do not use dovecot-directors or -proxies. I just have a floating IP on the servers to do failover. I had the problem today that in one user's INBOX and one if his mailfolders got flooded with hundreds of thousands of duplicates. How this happened is another issue (of someone has an idea it would be more than welcome) for which I will start another thread. I remedied the situation by: 1. switching off dovecot on the standby-server to avoid duplicates getting replicated. 2. kicking the affected user from the master-server 3. running a doveadm force-resync on all his mailfolders (after removing the indices). Thereby I did get rid of the duplicates. (Note: doveadm deduplicate did not work because of index error) My question is now, what steps I need to take before enabling replication again (i.e. switching on the standby server), in order to avoid duplicates (if any) being replicated back to the master-server. Any hints are welcome. If you need more information I am happy to provide it, let me know. Best regards, Hp
