ACL Folders are open but not being displayed ? [2.3.3]
by Kunal A. 15 Mar '19

15 Mar '19

Hey, Could someone help figure out whats wrong with my config based on the debug below? What I am trying to achieve is to get email1(a)example.com to read emails in the Public directory that is stored on /run/media/computer/Storage/Email/fastmail/Archive with the preface Public/Archive . The ACL has been set for anyone with permissions to lookup,read,write as shown below:- doveadm acl get -u email1(a)example.com Public/Archive ID Global Rights anyone lookup read write But when I try to access the emails for email1(a)example.com , there are no folders. Could someone here help review my debug log and advise what could be causing this (dovecot -n output is provided below the debug message) Many thanks for assistance.

dovecot.conf "local hostname" uses only one resolved value
by James 14 Mar '19

14 Mar '19

https://wiki.dovecot.org/SSL/DovecotConfiguration#Different_certificates_pe… says: local 192.0.2.10 { # instead of IP you can also use hostname, which will be resolved However if the name resolves to multiple values only one is used. Test. Choose any name with multiple values, I created a local name: $ nslookup multi.lan Server: 127.0.0.1 Address: 127.0.0.1#53 Name: multi.lan Address: 192.168.1.2 Name: multi.lan Address: 192.168.1.3 Name: multi.lan Address: 192.168.1.1 Minimal dovecot.conf: local multi.lan { protocol imap { ssl_cert = </path/to/certs/multi.lan.crt ssl_key = </path/to/certs/multi.lan.key } } $ dovecot -n -c dovecot.conf # 2.3.5 (513208660): dovecot.conf ... local 192.168.1.2 { protocol imap { ssl_cert = </path/to/certs/multi.crt ssl_key = # hidden, use -P to show it } } Only 192.168.1.2 appears. In my real case with A and AAAA records, only the AAAA record is used. Testing with "openssl s_client -starttls imap ..." gives me the wrong certificate for the IPv4 address. Workaround: specify all addresses and do not use lookup. James.

dovecot/config processes one more time - which are safe to kill?
by Arkadiusz Miśkiewicz 14 Mar '19

14 Mar '19

Hello. The problem with dovecot/config processes never ending and spawning new one on each reload (https://www.dovecot.org/list/dovecot/2016-November/106058.html) is becoming a problem here: # ps aux|grep dovecot/config|wc -l 206 That's a lot of wasted memory - dovecot/config processes ate over 30GB of ram on 64GB box. Before killing dovecot/config processes: # free -m total used free shared buff/cache available Mem: 64437 61656 483 0 2297 after: # free -m total used free shared buff/cache available Mem: 64437 23676 37822 0 2939 Currently on dovecot 2.3.3. I guess it's very low priority to handle that, so: how can I figure out which dovecot/config processes are safe to be killed by external script? Does "all beside 2 newest ones" rule look sane?

Quota questions
by Peter Hudec 14 Mar '19

14 Mar '19

Hi all, I’m a little bit confused about the quota plugin in dovecot and fighting the the issues the people had years ago. I spent readingg the old archives and the mailing list for 3 days and not able to get work some features. Single user quota is fine and simple, the group quota /for example domain based/ makes me unhappy. Setup: CentOS7, dovecot comunity repo, dovecot 2.3.5 1) domain quota recalc domain quota recalc do not work properly. The domain qouta usage is worknig well, hwhen receiving/deleting mail, generaly if the operations are incremental. But if I run domain quota recalc, the doveadm is setting the domain quota after each user calculation, that means the domain quota is set to the last user. 2) multiple quota roots and rules According the documentation, there could be possible, from the sample configuration file # Multiple quota roots are also possible, for example this gives each user # their own 100MB quota and one shared 1GB quota within the domain plugin { quota = dict:User quota::proxy::quota quota2 = dict:Group quota:%d:proxy::quota_domain quota_rule = *:storage=1024M quota2_rule = *:storage=2048M } But If I run [TEST] root(a)mail-store01.test.host.sk: /etc/dovecot # doveadm quota get -u '*' Username Quota name Type Value Limit % test01(a)test.host.sk User quota STORAGE 1 1024 0 test01(a)test.host.sk User quota MESSAGE 1 - 0 test01(a)test.host.sk Group quota STORAGE 7 - 0 test01(a)test.host.sk Group quota MESSAGE 3 - 0 test03(a)test.host.sk User quota STORAGE 7 1024 0 test03(a)test.host.sk User quota MESSAGE 3 - 0 test03(a)test.host.sk Group quota STORAGE 7 - 0 test03(a)test.host.sk Group quota MESSAGE 3 - 0 The idea is to have overall domain quota, but for user able to set it’s personal quota. regards Peter

dovecot-keywords are not preserved any more when moving mails between folders

replication dropped imap flags
by Patrick Cernko 14 Mar '19

14 Mar '19

Hi list, I think, I found a bug in the replication setup, that drops (custom) flags like Thunderbird labels. I have set up a simple 2 node setup to reproduce and explain it: Host adove.mpi-klsb.mpg.de and bdove.mpi-klsb.mpg.de (doveconf -n attached) have dovecot-imapd (from repo.dovecot.org) installed on an ext4 filesystem. They only have one account "test" via /etc/dovecot/userdb ("test:testpassword:::Test User::/bin/bash:"). It's mailbox contains one message, that is flagged with "$label1": doveadm -f flow fetch -u test 'guid flags' ALL guid=d1516a2b5c08fc5b541d00005a350039 flags=\Recent $label1 Now I simulate a node reinstall on adove by uninstalling dovecot, removing all remnants, reinstalling and configuring it again: apt purge dovecot-core dovecot-imapd rm -rf /var/vmail /var/lib/dovecot /etc/dovecot apt install dovecot-imapd # disable system auth : > /etc/dovecot/conf.d/auth-system.conf.ext # create /var/vmail install -d -o nobody -g nogroup -m 700 /var/vmail # create userdb echo 'test:testpassword:::Test User::/bin/bash:' > /etc/dovecot/userdb # create /etc/dovecot/local.conf # not described here, the resulting doveconf -n is attached! service dovecot restart When I check the flags of the mail of user test now, the "$label1" is disapeared on both machines, even after "doveadm replicator replicate -f test": doveadm -f flow fetch -u test 'guid flags' ALL guid=d1516a2b5c08fc5b541d00005a350039 flags=\Recent Any hints what I am doing wrong here or is this really a bug?

Am I right to assume certificate renewal with the same filename requires a dovecot reload/restart
by Guido Goluke, MajorLabel 14 Mar '19

14 Mar '19

Running dovecot 2.2, apologies if this question has been asked before: I've done the research but couldn't find anything. I run a server that uses dovecot as a MUA for Postfix and have a Let's Encrypt certificate that auto-renews through certbot on Ubuntu server 16.04. Dovecot did not pick up on the new certificate for the hostname. It did after a restart. To be clear: Let's Encrypt overwrites the previous certificate using the same path and filename. Am I right to assume that Dovecot needs a reload/restart after the certificate has been renewed in order to 'pick up' on the new certificate and if so, would I require a reload or a restart? Thank you in advance -- MajorLabel
