dovecot-openssl-common.c and [-Wincompatible-pointer-types]
by Rupert Gallagher 18 Mar '19

Warnings from clang 7.0 when compiling dovecot-openssl-common.c from dovecot 2.3.5 with openssl 1.1.1a. This is dovecot's configuration: > config_options="--prefix=$prefix \ > --sysconfdir=$prefix/etc \ > --datarootdir=$prefix/share \ > --mandir=$man \ > --docdir=$doc \ > --with-docs \ > --with-ssl=openssl --with-ssldir=$prefix/etc \ > --with-sodium \ > --with-libiconv-prefix=/opt/libiconv \ > \ > --with-bzlib=no \ > --with-gssapi=no \ > --with-ldap=no \ > --with-lucene=no \ > --with-lz4=no \ > --with-lzma=no \ > --with-pam=no \ > --with-solr=no \ > --with-sql=no \ > --with-vpopmail=no \ > --with-zlib=no \ > \ > --enable-dependency-tracking"; Note on passing: --with-ssldir=$prefix/etc is ignored by the configurator, as it forces $prefix/etc/dovecot.

Dovecot logrotation - old journal files are still in use (second attempt)
by Denis V Razumovskiy 18 Mar '19

18 Mar '19

Hi all Sorry, it is the second attempt due to wrong format of the first message. In my Dovecot there are 3 files of logging (debug, info and .log) While executing logrotation, the new files are created, but the previos ones, namely dovecot.*.1 are still in use by the process Here is the logger process in memory: root 19140 0.0 0.0 4140 1576 ? S Mar12 0:06 dovecot/log Here the files it uses after the daily logrotation had happened: # lsof -p19140 |grep log ... log 19140 root 33w REG 9,3 811 417675 /var/log/dovecot.log.1 log 19140 root 34w REG 9,3 2842123 417681 /var/log/dovecot.info.1 log 19140 root 35w REG 9,3 14853918 417683 /var/log/dovecot.debug.1 ... After the manual issue 'doveadm log reopen` command the files are changed to # lsof -p19140 |grep dovecot\\\. ... log 19140 root 33w REG 9,3 0 417651 /var/log/dovecot.log log 19140 root 34w REG 9,3 121374 417690 /var/log/dovecot.info log 19140 root 35w REG 9,3 916153 417691 /var/log/dovecot.debug as it is expected to be. I use the logrotate config for dovecot instance: /var/log/dovecot.log /var/log/dovecot.info /var/log/dovecot.debug { daily rotate 14 missingok notifempty compress delaycompress sharedscripts postrotate doveadm log reopen chmod 666 /var/log/dovecot.log chmod 666 /var/log/dovecot.info chmod 666 /var/log/dovecot.debug endscript } At the same time, dovecot itself still uses previous logs: # lsof |grep var\/log\/dovecot\. dovecot 19138 root 8w REG 9,3 12962 417613 /var/log/dovecot.log.1 (deleted) dovecot 19138 root 9w REG 9,3 4097250 416836 /var/log/dovecot.info.1 (deleted) dovecot 19138 root 10w REG 9,3 23816347 417603 /var/log/dovecot.debug.1 (deleted) What can be the root of the issue? I use Dovecot as LDA for Postfix with system users, mbox mail format. System Slackware 12.0 x86, Postfix 2.4.5, Dovecot 2.2.36. Interconnect Postfix-Dovecot has been made via `mailbox_command = ...' Dovecot was compiled from sources Logging configuration (file conf.d/10-logging.conf) contains the following: log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info debug_log_path = /var/log/dovecot.debug auth_verbose = yes auth_verbose_passwords = yes auth_debug = yes mail_debug = yes verbose_ssl = yes plugin { } Could the fact, that Postfix require Dovecot logs to be accessible someway, result in such a weird behavior? To allow other processes to access Dovecot logs I had to chmod 0666 all the current logs while integrating Dovecot into Postfix delivery (please see `chmod' commands in the logrotate config above) Please ignore my previos post https://dovecot.org/pipermail/dovecot/2019-March/115075.html Thank you Denis Razoumovskiy

LDAP users issue
by Anushka Bandara 18 Mar '19

18 Mar '19

Hi Team, I have enabled LDAP authentication with webmail client and it works successfully. But I found an error with LDAP user's mail. Email is not loaded when I log with an LDAP user. Login phase is successful and mail box is the issue. I created a mail user without including LDAP and that user works fine. Issue comes only with LDAP users. *Anushka Bandara* Research Engineer Lanka Software Foundation +94715846018

`Spam' folder creation for multiple users
by Marek Kozlowski 17 Mar '19

17 Mar '19

:-) I've just added pigeonhole and a simple sieve script: ------------------------------------------------- require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "Spam"; } ------------------------------------------------- If a user has this folder (`Spam') it works fine. If they haven't it results in an error. 1. Can I modify the script to create this folder if the need arise? 2. If not - what's the most recommended way of adding this folder for all users (~1000)? Thanks! Best regards, Marek

lda: Unknown mail storage driver maildir
by Rob De Langhe 17 Mar '19

17 Mar '19

hi all, I have a successful (self-compiled from source code) Dovecot v2.2.16 setup active on my Solaris-10 server, with mails stored in user's $HOME/Maildir The mails are fetched from the ISP with "fetchmail", using a "cron" job fetchmail -f $HOME/etc/pop3.myisp where the file "$HOME/etc/pop3.myisp" contains set logfile fetchmail.log poll pop.myisp.be with proto POP3 user myIspmailLogin there with password myIspPwd is rob here nokeep mda "/programs-3.2/amd64/64/libexec/dovecot/deliver" Now I want to get it also running on a Debian server, with the same Dovecot version, and exactly the same config files, but here I get the following messages in "/var/log/mail.log" when launching a "fetchmail" attempt : Mar 17 14:36:20 apps_b dovecot: lda(rob): Debug: Effective uid=1000, gid=1000, home=/home/rob Mar 17 14:36:20 apps_b dovecot: lda(rob): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir Mar 17 14:36:20 apps_b dovecot: lda(rob): Error: User initialization failed: Namespace '': Unknown mail storage driver maildir Mar 17 14:36:20 apps_b dovecot: lda(rob): Fatal: Invalid user settings. Refer to server log for more information. So it seems to be complaining about "maildir" storage driver ?! My config is: # /programs/3.4/x86_64/64/sbin/dovecot -n -c /usr/local/dovecot/dovecot.conf # 2.2.16: /usr/local/dovecot/dovecot.conf # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.4 disable_plaintext_auth = no first_valid_gid = 1000 first_valid_uid = 1000 last_valid_gid = 1500 last_valid_uid = 2000 mail_debug = yes mail_location = maildir:~/Maildir namespace inbox { location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = * driver = pam } postmaster_address = rob(a)mydomain.be ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd }

LMTP Proxy failure using master login via destuser field
by Dirk 17 Mar '19

17 Mar '19

Hi list, I set up dovecot as IMAP proxy using a master user to login into the backend and it works beautifully. 👍🏻 Next I set out to do LMTP proxying and I struggled (initially). I got the log message: Mar 17 11:23:44 mail postfix/lmtp[2665]: 99A3F219C8: to=<johnny(a)doe.com>, relay=10.15.1.2[10.15.1.2]:24, delay=5.1, delays=4.9/0.05/0.01/0.07, dsn=5.1.1, status=bounced (host 10.15.1.2[10.15.1.2] said: 550 5.1.1 <"johnny(a)doe.com*director"@mail.server.com> User doesn't exist: "johnny(a)doe.com*director"@mail.server.com (in reply to RCPT TO command)) My director's passdb setting looked like this: passdb { driver = sql args = /etc/dovecot/sql/my-passdb.conf result_success = continue-ok result_failure = return-fail result_internalfail = return-fail } # Add director master user credentials if above succeeded passdb { driver = static args = proxy=y starttls=any-cert \ destuser=%u*director(a)example.com \ pass=correcthorsebatterystaple \ nopassword=y skip = unauthenticated } In the end I found that setting the `master` field instead of `destuser` solves the issue. It looks like LMTP does not know how to handle the master user separator although set. I this known/wanted behavior? Maybe this is something to mention on the wiki page, it took a while to figure this out...
