sieve scripts not synching for 2.3.5.1 pre-built
by Jan-Pieter Cornet 29 Jul '19

29 Jul '19

Hi, We're synching mailboxes, changing format from maildir to mdbox, using doveadm backup/doveadm sync. When still running 2.2.36, 'doveadm backup' also synched the sieve scripts, without issues. After the upgrade to 2.3.5.1, the sieve sync stopped working. We're using the pre-built 2.3 packages from https://repo.dovecot.org/ce-2.3-latest/debian/stretch In fact, when I now remove the dovecot-2.3 packages, and use my own old 2.2.36 packages, using the exact same config, the sieve scripts are being copied again. In 2.2.36, when I migrate a mailbox, I do see Pigeonhole being initialized. Eg: userimap-dev1:~ # doveadm -D backup -u xtra30 "doveadm -D dsync-server -u xtra30+mdbox=.8d1&4&03&xtra30" (note: that strange destination user signals to the auth proxy that we want the new mdbox storage instead of the default for this user) Debug: Loading modules from directory: /usr/lib/dovecot/modules Debug: Module loaded: /usr/lib/dovecot/modules/lib02_lazy_expunge_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_sieve_plugin.so [...skipping a bunch of lines...] dsync-local(xtra30): Debug: brain M: Mailbox Spam: local=88b39d12998d9e5cbb700000436edcce/0/1, remote=00000000000000000000000000000000/0/0: mailbox not selectable yet dsync-local(xtra30): Debug: brain M: Mailbox Test: local=801bb932e98d9e5c3d6d0000436edcce/0/1, remote=00000000000000000000000000000000/0/0: mailbox not selectable yet dsync-local(xtra30): Debug: brain M: Mailbox Trash: local=fc9b162b86479f5cc85a0000436edcce/0/1, remote=00000000000000000000000000000000/0/0: mailbox not selectable yet dsync-remote(xtra30): Debug: brain S: Skipping unchanged mailbox e7c1961d84479f5c885a0000436edcce dsync-local(xtra30): Debug: doveadm-sieve: Iterating Sieve mailbox attributes dsync-local(xtra30): Debug: sieve: Pigeonhole version 0.4.24 () initializing dsync-local(xtra30): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. dsync-local(xtra30): Debug: sieve: file storage: Using active Sieve script path: /var/mail/.8d1/index/7/oldsieve/x/xt/xtra30/dovecot.sieve [... skipping a lot of sieve debug lines that seem fine ...] dsync-remote(xtra30): Debug: sieve: file script: Opened script `xtra30-testfilter' from `/var/mail/.8d1/index/4/03/xtra30/sieve/scripts/xtra30-testfilter.sieve' dsync-remote(xtra30): Debug: doveadm-sieve: Assigned value for key `vendor/vendor.dovecot/pvt/server/sieve/default' (last change: 2019-03-29 22:27:41) dsync-remote(xtra30): Debug: brain S: Import INBOX: Import attribute vendor/vendor.dovecot/pvt/server/sieve/default: Nonexistent locally dsync-remote(xtra30): Debug: brain S: Import INBOX: Last common UID=0.

submission configuration issues
by Jean-Daniel Dupas 29 Jul '19

29 Jul '19

Hello, I'm having trouble configuring the submission proxy. I have configured the submission service as follow: submission_host = smtp.example.com submission_relay_host = localhost submission_relay_port = 8587 submission_relay_rawlog_dir = /var/log/dovecot/ submission_relay_trusted = yes My main issue is that until I login, dovecot-submission won't connect to the backend and query the capabilities and so won't report the right capabilities. That mean that the first EHLO message don't get the right capabilities list. " EHLO example.com 250-smtp.example.com 250-8BITMIME 250-AUTH PLAIN LOGIN 250-BURL imap 250-CHUNKING 250-ENHANCEDSTATUSCODES 250-SIZE 250 PIPELINING " This list don't contains VRFY, DNS, and SIZE is not specified (all of these is present in backend EHLO response). After login, if I send an new EHLO command, everything is properly reported. The raw log shows that unlike what the documentation says, dovecot don't try to connect to the backend until the user is properly logged. In my raw log I show that after I logged in dovecot-submission, the later open a connection to the backend and send a X-CLIENT command. Now, if I try to force the capabilities by using: submission_backend_capabilities = VRFY 8BITMIME DSN dovecot properly reports all SMTP capabilities in the first EHLO response, but it completely stops emitting X-CLIENT command to the backend and try to simply forward the command without authentication, which result in postfix rejecting the command with an unauthorized user error. What is wrong with my configuration ? Thanks. Jean-Daniel

Help with IMAP IDLE

29 Jul '19

Hi, I'm becaming crazy about this! I've asked before, not no matter what i do or conf, never works. How can i make IDLE work for real with MSOutlook, so that i can receive emails when they arrive, instead of changing folder/get out and in my account? Here's my conf, should it be reflected in postconf -n (is it the running conf?): ================== root@fastmail:/etc/dovecot# grep -ir idle * conf.d/20-imap.conf.ucf-dist:# If nothing happens for this long while client is IDLEing, move the connection conf.d/20-imap.conf.ucf-dist:# IDLEing. conf.d/20-imap.conf.ucf-dist:#imap_idle_notify_interval = 2 mins conf.d/20-imap.conf:imapc_max_idle_time = 1440 mins conf.d/20-imap.conf:# IDLEing. conf.d/20-imap.conf:#imap_idle_notify_interval = 2 mins conf.d/20-imap.conf:imap_idle_notify_interval = 1 min conf.d/20-imap.conf:#imap_client_workarounds = outlook-idle conf.d/10-mail.conf.ucf-dist:# When IDLE command is running, mailbox is checked once in a while to see if conf.d/10-mail.conf.ucf-dist:#mailbox_idle_check_interval = 30 secs conf.d/10-mail.conf:# When IDLE command is running, mailbox is checked once in a while to see if conf.d/10-mail.conf:#mailbox_idle_check_interval = 30 secs root@fastmail:/etc/dovecot# postconf -n|grep -i idle root@fastmail:/etc/dovecot#

Since multiple ,matches
by ＠lbutlr 27 Jul '19

27 Jul '19

I have a rule in sieve like the following: if anyof (header :contains ["to"] [ "box", "change", "cornell”, “twitter”]) { setflag "\\Seen"; fileinto :create "misc"; stop; } The messages that come in are using address extensions, so user+twitter(a)example.com, for example. The trouble is, this sieve recipe doesn’t get triggered and the message gets filed into the extension folder “twitter” or “cornell” instead of “misc”. I have a very similar recipe following that one: if header :contains "to" "root" { setflag "\\Seen"; addflag "$label5"; fileinto :create "root"; stop; } And that one works as I expect. Is that multiple match format valid for :contains (I’ve only seen it used for :regex)? I don’t get an error. Is there a way to run a debug log for the sieve recipe? Preferably for a single user. -- Vernon: Now this is the thought that wakes me up in the middle of the night.

corrupt mdbox index / zero mails showing in imap
by Mike 27 Jul '19

27 Jul '19

Hi, I have recently migrated (under emergency conditions) a dovecot imap/pop based server to a new instance. The mailboxes used mdbox format and due to various screwups I had corrupt indexes. I thought I'd cleaned this up but then I found that this new instance hadn't been set up correctly for nfs. Long story short, I still get users with new cases of corrupt indexes. The symptom is imap either showing NO mail in their inbox, or, not showing any recently delivered mail in the box, until I rm -f dovecot.map.index / doveadm force-resync -u user. It would be a huge help if there could be some method to detect if this is the case for any given user and to proactively do the force-resync process for them instead of waiting for that support call (or service cancellation...). I have looked around and have not found any tool capable of 'linting' an mdbox format inbox, and it seems like something like this should have been or would be an extremely useful debugging tool both during development as well as to troubleshoot stuff in the field. I would love to know if anyone either has such a tool, or any general suggestion how I could go about finding these cases and addressing them. I believe I have the nfs issue resolved and will not be creating new cases, so I just want to fix the ~3000 boxes I have now and move forward. Thank you. Mike-

dsync crash

25 Jul '19

Hello, I am getting a persistent seg fault while trying to sync our server to a new location. We are on 2.2.33.2, due for an upgrade but we have used dsync successfully in the past. In fact, we used it to populate this same instance. So I hope this is just a configuration issue.

lmtp with non ASCII Parameters changed in dovecot 2.3
by Matthias Lay 25 Jul '19

25 Jul '19

Hi, I updated from 2.2 to 2.3 and noticed lmtp rejects parameters containing non ASCII now. this worked with dovecot-2.2 lmtp. the string is already denied after reading in "smtp_command_parse_parameters()" mail from:<bluö> 500 5.5.2 Invalid command syntax is there a plan to change this behaviour, or to implement the SMTPUTF8 extension in lib-smtp? I guess thie would fix Michals "Dovecot LMTP rejecting mail from address with apostrophe" Problem too. Greetz Matze

Hi Arnold, thanks for your assistance. I solved the issue right now by changing prefix = Shared/%%u/ to prefix = Shared/%%n/ This omits the @mydomain.de part which holds the dot causing the trouble. Why this became a problem due to the update I wouldn't know.

Re: Dovecot 2.3.6 on Solaris10: build issues, segfaults
by Joseph Tam 23 Jul '19

23 Jul '19

Looking further into this segfault at settings-parser.c:setting_copy():1519 *dest_size = *src_size; *src_size points to type size_t (typedef unsigned long), a 4-byte aligned value consistent with a 32-bit build. This is mismatched with declared type (gdb) whatis src_size type = const uoff_t * (gdb) whatis uoff_t type = unsigned long long (gdb) p sizeof(uoff_t) $1 = 8 resulting in the segfault when *src_size is dereferened. The implied condition of this code segment is typeof(uoff_t)==typeof(size_t) which is clearly not the case. I'm not sure how/if uoff_t is defined, but configure reports checking for uoff_t... no checking type of off_t... long long The latter is weird, because if I compile and run using the same compiler flags #include <stdio.h> int main(void) { printf("%d %d\n",sizeof(long long),sizeof(off_t)); } the output is "8 4".

Dovecot with MySQL over SSL.
by Reio Remma 22 Jul '19

Hello! I'm attempting to get Dovecot working with MySQL user database on another machine. I can connect to the MySQL (5.7.26) instance with SSL enabled: mysql -h db.mrst.ee --ssl-ca=/etc/dovecot/ca.pem --ssl-cert=/etc/dovecot/client-cert.pem --ssl-key=/etc/dovecot/client-key.pem --ssl-cipher=DHE-RSA-AES256-SHA -u vmail -p However if I use the same values in dovecot-sql.conf.ext, I get the following error: Jul 19 00:20:18 turin dovecot: master: Dovecot v2.3.7 (494d20bdc) starting up for imap, lmtp, sieve (core dumps disabled) Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Database connection string: connect = host=db.mrst.ee dbname=vmail user=vmail password=stuff \ ssl_ca=/etc/dovecot/ca.pem \ ssl_cert=/etc/dovecot/client-cert.pem \ ssl_key=/etc/dovecot/client-key.pem \ ssl_cipher=DHE-RSA-AES256-SHA If I leave the ssl_cipher unset, I get: Jul 19 00:23:41 turin dovecot: auth-worker(83069): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: Failed to set ciphers to use - waiting for 1 seconds before retry Any ideas?

Pure-FTPd’s SNI daemon
by Felipe Gasper 22 Jul '19

22 Jul '19

Hello, Pure-FTPd just adopted an interesting approach to SNI support: a separate daemon that serves cert chain and key for a given hostname. What would be involved in having Dovecot support this daemon? It would alleviate the need right now for a very large “sni.conf” file on hosts that serve thousands of domains. Thank you! -Felipe Gasper Mississauga, ON

Dovecot eBook

22 Jul '19

Hi Timo I have a strange question. I bought the Dovecot Book off Amazon. I can easily prove it with a picture and/or my receipt off Amazon. I still have it o my library but I don’t like to travel around with it. Is there a way for me to get a PDF copy? I just checked Amazon and there is still no PDF version available there.
