POP3 & IMAP inbox setting for virtual
by Michael Fox 01 Aug '16

01 Aug '16

Posted Monday 7/25. Haven't seen a response. Trying again: --- This is a noobie question, so bear with me if it's not worded correctly: Primary Requirements: 1) I'd like to have two namespaces - one private/per-user, and one public (visible by all logged-in users). The public mailbox(s) would be used to distribute information to all users. 2) I'd like both POP3 and IMAP users to see both namespaces. As I understand it, this requires the use of the virtual plugin for POP3, in order to create a virtual namespace which would mix together the private and public namespaces into one mailbox. I have read: http://wiki.dovecot.org/Plugins/Virtual https://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve- spamfilter-regel-fur-pop3-nutzer/ (via Google translation) The example uses a CASE statement in the MySQL userdb query. As I understand it, this is done to set which namespace contains the inbox: the private namespace or the virtual namespace -- depending on if the user is connected via the imap or pop3 service, respectively. Question: how do I accomplish the same goal (setting the proper namespace for the inbox) when using a passwd-file style flat file userdb? Thanks, Michael

self signed certs and dovecot imaps : howto? tlsv1 alert unknown ca
by hanasaki＠gmail.com 01 Aug '16

How do you setup dovecot to use a self signed cert? One server will be connected to the internet. One will be totally internal and have no runtime access to the internet. Getting the below error msg. Also, I think I have a TLS 1.0 and need a 1.2 cert?... Thank you. Jul 28 20:09:27 host dovecot: imap-login:: user=<>, rip=10...., lip=10...., TLS: SSL_read() failed: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca: SSL alert number 48, session=<kK2aELspLpkKAQF5>

migration from cyrus; seg fault at mail_namespaces_get_root_sep
by vstargben＠gmail.com 31 Jul '16

31 Jul '16

Hi all, I am currently trying to migrate from cyrus to dovecot on a new system. Though only few accounts, I decided to use the mdbox format. To convert I use cyrus2dovecot first, then I use dsync to import the mailboxes. For compatibility I set the namespace of inbox to prefix = INBOX. and separator = . (as described here: http://wiki2.dovecot.org/Migration/Cyrus http://wiki.dovecot.org/Namespaces) This works except that the clients (mutt and Thunderbird) show an additional folder/mailbox "INBOX" below the inbox. How can I fix that? Should I add a prefix during conversion and not change the namespace config? On disk, the subfolders are next to INBOX. Well, I then tried to set list = children instead of "yes" for namespace inbox. On login a segfault occurs with this setting. See the information and backtrace below.

Occasional lock timeouts on Linode VM with Dovecot Replication
by Reuben Farrelly 31 Jul '16

31 Jul '16

I've been seeing periodic entries in my dovecot logs like this: dovecot[3464]: dsync-server(kaylene): Error: Couldn't lock /home/kaylene/.dovecot-sync.lock: Timed out after 30 seconds: 3 Time(s) dovecot[3464]: dsync-server(reuben): Error: Couldn't lock /home/reuben/.dovecot-sync.lock: Timed out after 30 seconds: 1 Time(s) They occur several times per day, but don't appear to have any obvious cause and I am not aware of any problems this is causing. [They could be the cause of some reappearing UID type messages that also periodically are logged, but I can't be sure] They occur on a lightly loaded Linode VM, KVM Paravirtualised and with only local SSD disk storage. The VM is a Gentoo Linux VM running the latest kernels that Linode provide. I also saw this problem under Xen. The dovecot setup is a dsync replication between two hosts, there is about 150ms of latency between them. The host where I am seeing these messages on (lightning) is a dovecot replica of another system (thunderstorm). I am using Maildir storage. Thunderstorm sees the vast majority of the client side reads and writes and lightning just functions as a not-so-active replica. Thunderstorm is also a VM but on VMware (also on SSDs). This system has never had this problem. I've had this across many dovecot versions going back many months now so it's impossible to pinpoint when this started. I am currently running dovecot -git master-2.2 branch at the moment. I've never seen disk latency in excess of 30s on any system either so I doubt that raw IO is the cause. I don't have any settings specified in 10-mail.conf in the Mail processes section relating to locking or mmap. Has anyone else experienced this and/or any ideas about where to look next to determine the root cause? Is this a common warning to see in cloud hosted/shared environments? Reuben

Master-Master replication question
by Remko Lodder 29 Jul '16

29 Jul '16

Dear list, I have setup a master-master replication setup. My primairy MX's send email over on a DNS loadbalanced way, so DNS is doing some kind of round-robin way of sending mail to both master servers. I found out, that on one of the two machines, the email synchronisation is heavily delayed. Lets assume server A receives a mail from the MX; it synchronises almost instantly with the other server. Whenever server B receives the email, it could take up to several hours to synchronise the email, it seems that it is not detected prior. It is also interesting to see, that the mailboxes on server A (Where users login to retrieve their email via webmail/clients) are significantly smaller then the mailboxes on server B. When investigating, it seems that "older" mailboxes (or storage rather since we use mdbox) are still there on server B, which already had been removed on server A. My personal mailbox was 170MB on server A, while it was still 2.5GB on server B. (which was around that size before cleaning up the mailsboxes). I enabled debugging on the servers, and I see rather quick : "Replication requests" on server A, but when getting an email on server B, I do not see the request at all. My servers are both running the same version, same configuration (utilizing puppet), both running on ZFS and FreeBSD. Where server B is more loaded in it's memory because of some bhyve VM's and the server A does not run any VM. Does someone have any pointers on where to look? Thanks in advance ;-) Remko Included below the configurations from server A and B: Server A: # 2.2.25 (7be1766): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.14 (099a97c) # OS: FreeBSD 10.3-RELEASE-p2 amd64 auth_mechanisms = plain login disable_plaintext_auth = no doveadm_password = #

The result is: ?The identify of > server 45.56.81.181 cannot be verified. The certificate for this > server is invalid.? Well, yes, that's what you would expect. You've told your mail client to connect to "45.56.81.181", the client starts the SSL negotiation and finds the certificate is made out for "sheepsystems.com", and your mail client complains about the mismatch (a possible MITM attack). This is what you want SSL enabled system to do. Since 45.56.81.181 does not map to "sheepsystems.com" yet, you can short-circuit DNS and add a direct mapping to your Mac by adding this to /etc/hosts: 45.56.81.181 sheepsystems.com then reconfiguring your mail client to use the server "sheepsystems.com". This will appease the SSL constraint. > appear in /var/log/mail.log [2]. Don't know what this is about -- probably your Mac bailing out on authentication. Joseph Tam <jtam.home(a)gmail.com>

Client app says my chained Comodo cert is invalid
by Jerry Krinock 28 Jul '16

28 Jul '16

I’ve configured Dovecot and Postfix on a new VPS running Ubuntu 16.04, using Linode’s tutorial [1], to require authentication and SSL encryption for both POP3 and SMTP. All looks OK to me except, when my email client app (macOS Mail.app) tries to log in, it says that my cert is invalid. The trouble appears when I attempt to configure a client account in Mail.app on my Mac. For the POP server name, I enter my VPS’ “45.56.81.181", because public DNS is still pointing to my existing host. I set the account to use the Apple TLS certificate, and then click to save this new account info. Before saving, Mail.app checks my entries by attempting to log in. The result is: “The identify of server 45.56.81.181 cannot be verified. The certificate for this server is invalid.” At the same time, on my new server, some entries appear in /var/log/mail.log [2]. The certificate in question is a new PositiveSSL/Comodo cert I bought the other day. It works OK for serving web pages - I mean, on this same Mac, when I visit my under-construction site at https://45.56.81.181 in Safari or Firefox, I get the padlock icon and no warnings. Comodo gave me two two files, a “.crt” which contains my cert, and a “.ca-bundle.crt” which contains their certs. Per Dovecot documentation, I concatenated these into a “chained” file containing all 3 certs, starting with mine. In /etc/dovecot/conf.d/10-ssl.conf, I set ssl_cert = this “chained” file. I tried adding the two original cert files to macOS Keychain.app with “Always trust” but that did not help. Being new at this, I would appreciate any suggestions. My `dovecot -n` output is below [3].

Sieve vacation address problem
by Harald Leithner 27 Jul '16

27 Jul '16

Hi, it seams I have a problem with the vacation script. The problem is that the vacation answers to a address that is not listed in the sieve script. I checked the postfix master.conf which delivers to lda correct parameter. In the logfile you can see that that office(a)example.com received a message that get delivered to user(a)example.com (with the sievescipt) and to office(a)example.com (another user without script). The sieve script has the :addresses parameter only set to user(a)example.com Is something wrong with my setup? We use roundcube + sievemanage to create sieve scripts. Sievescript: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["date","relational","vacation"]; # rule:[Urlaub] if allof (currentdate :zone "+0200" :value "gt" "date" "2016-07-22", currentdate :zone "+0200" :value "lt" "date" "2016-08-08") { vacation :days 1 :addresses ["user(a)example.com"] :subject "Abwesenheitsnotiz" text: Thx i'm not here . ; } -------------- postfix
