ManageSieve: authenticate "EXTERNAL" not behaving correctly
by Marc Weustink 30 Nov '17

30 Nov '17

Hi, I've enabled client certificate authentication for imap and managesieve. When I use Thunderbird with the sieve plugin it tries to login, but times out. Initially I reported this to the sieve plugin, but we came to the conclusion that it managesieve is misbehaving. https://github.com/thsmi/sieve/issues/94 Thunderbird (win10-64) 52.4.0 (32bit) Sieve 0.2.3k Dovecot (Ubuntu 16.04.3 LTS) 2.2.33.1-1 (sid) What happens is the following (p=plugin sends m=managesieve sends) p:authenticate "EXTERNAL" "" m:"" The response is unexpected. According to RFC 5804 an empty challenge/response is sent as an empty string. So I would expect: p:authenticate "EXTERNAL" "" m:OK "Logged in." With the use of gnutls-cli I could reproduce (c=I send m=managesieve sends) gnutls-cli --starttls --x509keyfile marc_mail.key --x509certfile marc_mail.crt -p sieve 172.17.1.4 ... m:OK "TLS negotiation successful." c:authenticate "EXTERNAL" "" m:"" c:"" m:OK "Logged in." However if I try the "imap" syntax (rfc4959) I get logged in at once ... m:OK "TLS negotiation successful." c:authenticate "EXTERNAL" "=" m:OK "Logged in." Note that this is an imap only extention, "=" is an invalid base64 encoding. Marc

Would it kill you to design your software not to treat remote mail servers like personal servers that can serve up connections like candy?

iPhone/iPad IMAP connection bursts causes user+IP exceeded
by Joseph Tam 30 Nov '17

30 Nov '17

I frequently see this from my iPhone/iPad IMAP users: Oct 24 21:30:55 server dovecot: imap-login: Login: user=<user>, ... [... repeated 10 times ...] Oct 24 21:32:54 server dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=12): user=<user> Oct 24 21:32:54 server dovecot: imap(user): Logged out ... [... repeated 11 times ...] These bursts of logins/max/logouts would cycling on for a few minutes. Googling this problem seems to turn up lots of similar complaints about iOS mail mail clients. e.g. https://discussions.apple.com/thread/2547839?tstart=0 iOS mail readers do not limit connections limit as other mailreaders can. I could increase mail_max_userip_connections, but that just moves the goal posts. Using the new rawlog feature in 2.2.26 (thanks Dovecot team!), I was able to see that these connection bursts are caused by clients doing global searches. The rawlogs show each mailbox being SELECT'd and searched (e.g. From header string): 1477369968.730450 2 ID ("name" "iPad Mail" "version" "13G36" "os" "iOS" "os-version" "9.3.5 (13G36)") 1477369968.781932 3 SELECT {mailbox} 1477369968.961636 4 UID SEARCH RETURN (COUNT) 1:* NOT DELETED 1477369969.006087 5 UID SEARCH RETURN (ALL) 1:* NOT DELETED 1477369969.052701 6 UID SEARCH RETURN (ALL) {search-term} NOT DELETED 1477369974.624153 7 LOGOUT Questions: 1) How does this affect the user? I heard from one user that it makes global searches unusable because his reader just spins its wheel. I'm not sure whether this is impatience or this results in failed searches. 2) Is there a client-side fix (e.g. connection limiting)? Apple appears to be intransigent on addressing this. 3) Will maintaining search indices (e.g. solr) help with this? Maybe the searches are taking too long and the connections pile up waiting for previous searches to finish. Thanks, Joseph Tam <jtam.home(a)gmail.com>

XDOVECOT capability?
by Hogne Vevle 28 Nov '17

28 Nov '17

Hi! Here and there, I'm seeing mentions of a "XDOVECOT" capability - e.g. on https://documentation.open-xchange.com/7.8.2/middleware/components/search/c… . However, I can't seem to find any documentation on what this actually does. We need to add this capability to our servers in order for certain functionality of Open Xchange App Suite to work properly (as seen in the link above), but we don't want to blindly update our entire Dovecot cluster just because their docs tell us to :) Can someone, please, shed some light on what other effects we can expect to see after enabling this capability, if any? Or is it simply a way of telling clients that "Hey, I'm a Dovecot server" - nothing else? Cheers, - Hogne

How to make dovecot access a MySQL database with a certain domain?
by Spike98 28 Nov '17

28 Nov '17

I am trying to make a mail server with Postfix using the Dovecot software. At the time of wanting to access my server from a mail client, it does not let me access and see the logs of my server with the command: $ service dovecot status with the following error: dovecot: auth-worker(2769): Error: mysql(127.0.0.1): Connect failed to database (postfix): Access denied for user 'postfix'@'localhost' (using password: YES) - waiting for 125 seconds before retry From what I understand of this error is that it is trying to enter 'postfix' @ 'localhost' instead of the domain that I specify when I made the database that is mydomain.com How can you make dovecot go to MySQL with postfix(a)mydomain.com instead of localhost This is my Dovecot configuration /etc/dovecot/dovecot-sql.conf.ext driver=mysql default_pass_scheme=PLAIN-MD5 connect=host=127.0.0.1 dbname=postfix user=postfix password=postfix password_query=SELECT username,domain,password FROM usuarios WHERE username='%n' AND domain='%d' user_query=SELECT 1007 as uid, 1007 as gid, concat("maildir:/var/vmail",domain,'/',username,'/') as mail FROM usuarios WHERE username='%n' AND domain='%d' iterate_query=SELECT username,domain FROM usuarios

Imapsieve plugin?
by Bruce 28 Nov '17

28 Nov '17

Debian stretch. Dovecot 2.2.27 I was working with a document that references the imapsieve plugin. It references the /etc/dovecot/conf.d/90-imapsieve.conf file. The only reference I've found for it is https://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/IMAPSieve#Configuration. I've got dovecot-managedsieve and dovecot-sieve already installed. Am I missing something obvious here? Bruce M.

If you only have a small userbase with modest amount of mail, you can probably take your whole system down, do a one time migration, then cut over to the new system without too much downtime. If you have medium sized operation, then what you propose above would work. If you have a large userbase (or large user mailboxes), or you want to minimize downtime, you can incrementally migrate per user so that any particular user experiences a small window of outage, but the system is online for everybody else. This, of course, requires a lot more setup and planning. Joseph Tam <jtam.home(a)gmail.com>

doveadm backup or sync Read status
by DurgaPrasad - DatasoftComnet 27 Nov '17

27 Nov '17

Hello All, Sorry for reposting. Earlier I was in digest mode hence could not update the previous post. I am trying to migrate mail from a dovecot-2.0.13-1_129.el5 maildir to dovecot-2.2.10-8.el7.x86_64 centos 7 mdbox. I am using this command doveadm -v -o mail_fsync=never backup -R -u user(a)domain.com imapc: also tried doveadm -v -o mail_fsync=never sync -1 -R -u user(a)domain.com imapc: Both work flawlessly - Timo is great !!! - My issue is the source folders are all marked as read. The target folders of-course have unread OK. POP3 UIDLs are also ok (tested for one user). (1) My question is how can I make the source remain same (unread status etc.) so that I do migrate the various domains in a transparent manner and then switch servers ?. I have multiple virtual domains. (2) One more question do I have to do both imapc_ & also pop3c_ migration since I need the POP UIDLs to work properly for my outlook POP3 users after migration ?. I want to know the possibilities. Thanks DP --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Server migration
by Gandalf Corvotempesta 27 Nov '17

27 Nov '17

I've asked this before, but now it's time to move one server to another, I can't delay the operation anymore (the older server is failing) Both server are pretty old: 1.2.15 Probably, faster way would be to rsync all mailboxes from the older server to the newer one. I can start migrating everything while running then, stop the older server and sync only what is changed, keeping downtime at minimum. Any better solution ? No, server upgrade is not possible. Not at this time. It's too time consuming and I have to move asap.

Dovecot LMTP Proxy + STARTTLS?
by Tobi 27 Nov '17

27 Nov '17

Hi I got dovecot 2.2.26 on a Centos7 with latest updates. Dovecot is configured to act as director and delivers to my two backend servers. I enabled lmtp proxy on director to listen on port 24. Now I see in msg headers that the connection to the lmtp proxy uses STARTTLS but the connection from proxy to backend seems to be unencrypted. Is it possible to enforce the use of STARTTLS in the connection from the director to the backend as well? Regards tobi

Mark message as read when moved to Trash
by Felix Rubio Dalmau 26 Nov '17

26 Nov '17

Hi all, When I send a message to trash, without previously reading it (just with the subject is enough to say I do not want to read it), it remains as "unread". Then, clients (I am using Kmail) report there are unread message, when all of them are in Trash. The question, then is: Is there any way to automatically mark a message as read, when that message is moved to Trash? Thank you! Felix

set parameter per user
by A. Schulze 24 Nov '17

24 Nov '17

Hello, My dovecot server (2.2.33.2) work with "lmtp_save_to_detail_mailbox = no" Now I would like to enable the feature for /some/ users. Is that an option that could be set from an LDAP entry? I tried the following: modify my ldap schema to allow an optional attribute "lmtp-save-to-detail-mailbox" in /etc/dovecot/ldap.conf user_attrs = ... =lmtp_save_to_detail_mailbox=%{ldap:lmtp-save-to-detail-mailbox:no}, =... Now I set an ldapattribute "lmtp-save-to-detail-mailbox" with value "yes" for some users. Unfortunately messages to user+extension@domain are still delivered to INBOX/ while they should be delivered to INBOX/extension. I also tried to make the attribute accessible vi pass_attr and userdb_foo = ... because I use prefetch driver as userdb. I also disabled prefetching at all but no luck :-/ any Ideas? Andreas

Passing information from passdb to userdb
by Qmail 23 Nov '17

23 Nov '17

I'm trying to hack together a new authentication back-end and I wanted to know if it's possible to pass values from passdb to userdb in the auth_request structure at authentication time. I modified struct auth_request in auth-request.h to contain a new variable and it gets set properly in my passdb, however the value is not there when checking for it userdb. I'm very novice when it comes to Dovecot programming so any help is appreciated. Thanks!

[Dovecot] Configure replication in backup mode
by japerez 22 Nov '17

22 Nov '17

Dovecot 2.2.27 (c0f36b0) I'm trying to configure dovecot to backup all my email to a secondary server using "dsync". I got it working in "sync" mode or two-way synchonization, that means whatever happens in one server gets replicated in the other. However, documentation also says that a one way synchronization is posible, yet, after spending a good amount of hours searching, I failed to find what do I have to modify in my "30-dsync.conf" to do so. My 30-dsync.conf reads as follows: #This sets globally the port needed to connect #to the doveadm service #doveadm_port = 12345 # Set the password globally to use for connecting to # and requiring for the doveadm service doveadm_password = +++++++++++++ # Set the directory for validating certificates # provided when running with SSL enabled # Should be the standard OpenSSL certificate directory by default ssl_client_ca_dir = /etc/ssl/certs # Configure the doveadm service to listen service doveadm { inet_listener { # port to listen on port = 12345 # enable SSL # ssl = yes } } # Configure the aggregator service for notifications service aggregator { fifo_listener replication-notify-fifo { # Your mail user that's managing files generally is used here user = +++++ mode = 0755 } unix_listener replication-notify { user = +++++ mode = 0755 } } # Configure the replicator service service replicator { user = root process_min_avail = 1 unix_listener replicator-doveadm { user = root mode = 0755 } } replication_dsync_parameters = -d -N -l 30 -U -x nobody # Configure target hosts for replication # tcps can be tcp if you don't want to connect with SSL # :port can be omitted if it's the default set globally for doveadm plugin { mail_replica = tcp:*.*.*.*:12345 } Thanks.

dovecot initscript
by dovecot＠schoepfer.info 22 Nov '17

22 Nov '17

Hi, about https://wiki.dovecot.org/DovecotInit, i wondered about stop) if test $running = yes; then echo "Stopping Dovecot" kill `cat $pidfile` echo "." else echo "Dovecot is already stopped." fi ;; Is "doveadm stop" technically the same, or better/worse/safer? Does "doveadm stop" wait until all child processes are finished, or would "sleep 1" in the restart-function still be necessary in this case? Is "kill -HUP `cat $pidfile`" technically the same as "doveadm reload"? If it'a all fine to use doveadm in an initscript, i there a reason to not add "doveadm start" to doveadm functionality? Surely this is not that important, but maybe a bit more consistent. Thanks, Johannes

Log rotation and combining...
by SH Development 22 Nov '17

22 Nov '17

I have recently noticed that my dovecot-deliver.log is huge and wanted to start rotating it. So a couple of questions: 1. Can the dovecot-deliver.log be combined with the maillog, that gets rotated weekly? If it can be done, is it advisable? Since the inception of this particular server, the log file has been located in the /home/vmail directory. Is there a reason it shouldn’t be located in the /var/log directory with the maillog? 2. Separate from above, if I create a new logrotate script example as follows: # dovecot SIGUSR1: Re-opens the log files. /home/vmail/dovecot-deliver.log { missingok notifempty delaycompress sharedscripts postrotate /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true endscript } I get the following error only when cron tries to run it: /etc/cron.daily/logrotate: error: stat of /home/vmail/dovecot-deliver.log failed: Permission denied Owner on the log are vmail:vmail. If I manually force logrotate on this particular log, it works fine. Ethon

Entirely possible, since I don't have IPv6 and have completely disabled it as a result.

home folder for virtual users with autoexpunge setting
by felix＠kngnt.org 21 Nov '17

21 Nov '17

Hi all, I have enabled today the autoexpunge setting for Trash folders, and I am getting the following error when Dovecot starts: imap(<USER>): Error: autoexpunge: Couldn't create dovecot.autoexpunge.lock lock: User has no home directory I understand this is correct: as <USER> is a virtual user, it does not have home folder. Is there any way I can set the autoexpunge plugin to store the lock file in the virtual user email home folder? Thank you! Felix
