Replicator service in Dovecot 2.4 CE
by k v 18 Oct '23

18 Oct '23

On the documentation page for the upgrade to version 2.4 at https://doc.dovecot.org/3.0/installation_guide/upgrading/from-2.3-to-3.0/, it is mentioned that instead of the 'replicator' service (https://doc.dovecot.org/configuration_manual/replication/#replication-with-…) it is necessary to use an NFS cluster file system. Are you completely removing support for 'replication-with-dsync' starting from version 2.4? Are there any plans for built-in tools to implement an active/active or active/passive cluster in the community edition?

Dovecot behind Reverse Proxy and IP families
by Arnaud Cordier 12 Oct '23

12 Oct '23

Dear all, I am running Dovecot 2.3.20 in a Kubernetes cluster. The Dovecot container is exposed behind a Traefik load-balancer, which acts just like HAProxy would, using the Proxy Protocol in order to allow Dovecot to be aware of the real source IP of the client, as follows: Internet <-> Traefik load-balancer <---- Proxy protocol ----> Dovecot My setup works well over IPv4. Oct 12 19:11:33 imap-login: Info: Login: user=<arnaud@xxx>, method=PLAIN, rip=<my_ipv4_public_address> lip=10.42.4.21, mpid=1369531, session=<xxxx> Howevever, if the client originates from an IPv6 address, Dovecot does not seem to take the real IPv6 origin into account and fails. Oct 12 19:09:04 imap-login: Error: haproxy(v1): Client disconnected: Proxied local address is invalid (address=`10.42.4.21', rip=10.42.4.21) A network capture shows that the proxy protocol indeed sends the real IPv6 IP, that should be taken into account by dovecot: ......&.PROXY TCP6 2001:<rest_of_my_public_ip> 10.42.4.21 20200 993 The error seems to be raised in "core/src/lib-master/master-service-haproxy.c" line 553: 551 if (net_addr2ip(*fields, &local_ip) < 0 || 552 local_ip.family != family) { 553 e_error(hpconn->event, "Client disconnected: " 554 "Proxied local address is invalid " 555 "(address=`%s', rip=%s)", str_sanitize(*fields, 64), 556 net_ip2addr(real_remote_ip)); 557 return -1; 558 } 559 fields++; I suppose that the issue is related to the fact that the client originates from an IPv6 then the reverse proxy forwards the connection to Dovecot over IPv4, which results in the "local_ip.family != family" condition to be true. Why is such a restriction implemented ? It is to be noted that I implemented the exact same load-balancer architecture for postfix, which successfully handles an IPv6 real IP over an IPv4 connection. I temporarily fixed the issue by setting an IPv4 only DNS record for my imaps domain name, however, do you think that a fix could be implemented in Dovecot?

spool move/rename question
by Dave McGuire 09 Oct '23

09 Oct '23

Hi folks. Our mail server's spools are structured like this: /var/mail/<domain>/<user> We have an existing user with a lot of mail that we need to move from one domain to another. Our mail system is database-backed so changing the account is trivial, but can I just move the <user> directory from the structure above from one <domain> directory to another and expect everything to be ok? Or is there a better approach? (of course I'll do a backup first) Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

qp and Invalid quoted-printable input trailer: '=' not followed by two hex digits
by Arkadiusz Miśkiewicz 09 Oct '23

09 Oct '23

I have a mail (attached) for which dovecot reports: imap(test): pid=<32688> session=<UOVJ/0UHlM3B7y+g>, Error: Mailbox INBOX.test: UID=1: read(<binary stream of mailbox INBOX.test UID 1>) failed: read(/var/mail/test/.test/cur/1695887652.M710714P17846.mbox13:2,RS) failed: Invalid quoted-printable input trailer: '=' not followed by two hex digits and I fail to see why. There is = used at the end of lines as soft-line break. Also if you delete "przez system Spa=" it works. If you lave it and delete "<br>=" line it also works. Doesn't seem to be consistent. Is dovecot too restrictive here? dovecot 2.3.20 and 2.3.21 -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

bug report: lmtp fails on root-squashed NFS filesystem
by Anne Bennett 09 Oct '23

09 Oct '23

Hi, all. I'm trying to set up Postfix with dovecot LTMP delivery on a host where the user files (/var/spool/mail as well as home directories) are on NFS filesystems, which are exported root-squashed to the mail server. I definitely don't want to give the mail server root permissions on the user files. LMTP delivery fails with this logged message (e.g.): Nov 16 17:51:36 lust dovecot: lmtp(anne)<16830><mkkzEPg1lGG+QQAAs/mAJw>: msgid=<202111162229.1AGMTfAO024765(a)vindemiatrix.encs.concordia.ca>: save failed to INBOX: Read-only mbox I found this posting where someone else had a similar problem and traced it in some detail back in 2019: https://dovecot.org/list/dovecot/2019-February/114611.html but apparently no one answered the fellow. In order to check that this is indeed the same problem, I temporarily changed the INBOX definition to make it write into /var/tmp/ (on a local filesystem), and delivery worked. I then temporarily changed the INBOX definition to make it write into an NFS filesystem with root NOT squashed, and again it worked (after I chmodded the directory to 1777 to allow any user to create a file). I believe that the person who wrote the above posting is correct: at some point, file access is (incorrectly) checked as root instead of as the target user. This is a bit of a showstopper for me. Any plans to address this? I attach the output of "dovecot -n", fwiw, but I don't think that this is a configuration problem...

Dovecot services not starting

Hi, I'm running dovecot 2.3.16 on Ubuntu 22.04.2. But when I start dovecot, I can only see that the services are failing to start.

[b]Pay Someone to Take My Online Course?[/b] Different understudies who battle with reworking school, work, and family obligations select online class tutors to assist them with finishing their tests and complete their coursework.

This article will examine a piece of the things you ought to remember going before enlisting an online class help association. It's clearly a fact that online classes can be truly troublesome, particularly for working professionals who have a clamoring plan. Oftentimes they are searching for someone to take a whole course or individual tasks for them, to assist with managing their grades and moderate their strain. Nonetheless, be wary of affiliations that guarantee too wonderful to be authentic. They could charge you enormous totals for their associations and end up not conveying.

Online classes are eminent among understudies who need to save time on education and spotlight more on work or other private issues. These merge understudies who are taking courses while working and attempting to change family and profession responsibilities, military understudies on sending, and understudies with genuine inadequacies or sickness that make it pursuing for them to go to classes. Unfortunately, there are many tricks that confirmation to take online courses for you. These affiliations charge ridiculous totals and don't complete their obligations. They may also hand you over to your school. Tolerating that they do, you could be killed from your underwriting project or even suspended or removed from school.

They may comparatively have the decision to help you with beating any learning handicaps you have. Copyright infringement suggests utilizing someone else's words and thoughts without their endorsement. It is viewed as a kind of cheating and can accomplish a delicate grade or even send off from school. It is difficult to ensure that a used professional won't phony.

Re: How to reduce the number of UNIX sockets?

05 Oct '23

From: Steve Litt <slitt(a)troubleshooters.com> > Recently I've been getting the dreaded X error "Maximum number of > clients exceeded", so I performed an lsof -U to find who was using > UNIX sockets. This uncovered a buggy looping program I wrote using up > gobs of UNIX sockets, along with some browsers, dbus-daemon, electron > (used by vscode), smbd, and Dovecot, which uses 36 UNIX sockets. Only 36? The number of sockets seems to scale proportionally with the number of users. The login process of my service easily consumes several hundred sockets and could on occasions run into the thousands. (See also my previous posts on socket starvation.) Each client connection will consume a few sockets -- it uses maybe a few more than some applications do as they separate privileged daemons from worker daemons, and pass data around via sockets, but socket use if within reason. > I can kill dbus-daemon and the buggy program I wrote, minimize use of > browsers, disable smbd except when I (rarely) need it, but can you > think of things I can do to reduce the number of UNIX sockets used by > Dovecot on my machine? You can limit the number of clients per IP (e.g. mail_max_userip_connections) to lower the number of concurrent mailboxes that are open. Or use the idle process facility to park inactive connections (not sure if that frees sockets). Or cap the number of clients (process_limit, service_count, etc.), but if you're bumping up against those limits, you've either underprovisioned your service or you have something misconfigured. (Again, see my previous post on service_limit.) Maybe you need to *increase* those limits if you're hitting some client limit in regular use. From what you describe, you resolved the cause of your socket starvation whose cause was not dovecot. I'm not sure what you hope to gain by saving a few sockets that dovecot uses just to make headroom for a buggy script. Joseph Tam <jtam.home(a)gmail.com>

How to reduce the number of UNIX sockets?
by Steve Litt 04 Oct '23

04 Oct '23

Hi all, I'm using Dovecot version 2.3.21 on an up to date Void Linux on a 6 core 12 thread Ryzen with 48GB RAM, 1TB NVMe, and 12TB of 7200 RPM spinning rust hard drives. Recently I've been getting the dreaded X error "Maximum number of clients exceeded", so I performed an lsof -U to find who was using UNIX sockets. This uncovered a buggy looping program I wrote using up gobs of UNIX sockets, along with some browsers, dbus-daemon, electron (used by vscode), smbd, and Dovecot, which uses 36 UNIX sockets. I can kill dbus-daemon and the buggy program I wrote, minimize use of browsers, disable smbd except when I (rarely) need it, but can you think of things I can do to reduce the number of UNIX sockets used by Dovecot on my machine?

I found a reference to a similar issues here: https://www.dovecot.org/list/dovecot/2010-March/047925.html I know IMAP rfc say nothing about removing the keywords/PERMANENTFLAGS (they can only be added https://www.rfc-editor.org/rfc/rfc3501.html#page-64) , therefore I wonder if it is possible to create a Dovecot plugin to accomplish this task ? Technically it is possible to do now via the following steps: 1. Ensure the "unwanted" user defined keyword/flag is remove from all messages in a folder (Folder A) 2. Create a temporary folder (Folder A_temp) 3. Move all messages from Folder A -> Folder A_temp 4. Delete Folder A 5. Rename Folder A_temp -> Folder A As you can see this highly inefficient and awkward and even if the unwanted keyword does NOT appear in Folder A anymore , it still can be found in '~/Maildir/dovecot-keywords' file Alternatively, if it is hard to create a plugin that would remove the keyword for good, would something like this be easier: 1. Define a list of "allowed" user defined keywords 1a. Perhaps this list can be defined via METADATA extension on per folder basis 2. Reject(or discard) "not allowed" keyword sent via the +FLAGS / +FLAGS.SILENT commands Any helpful plugin example or code references would be greatly appreciated. Thank you very much, Sergey Mosin

Compression: all or nothing?
by Alex King 03 Oct '23

03 Oct '23

Using 2.3.13 (89f716dc2) (debian package), with mdbox storage. I considering adding the zlib plugin. I understand that reading mail can cope with either compressed or uncompressed mailboxes. I'm wondering if I can leave the main storage uncompressed, while having the alternate storage compressed. There does not seem to be a way to configure this, from https://doc.dovecot.org/settings/plugin/zlib-plugin/ it seems compression (on saving emails) is an all-or-nothing option? Can I leave zlib_save unset in my main configuration, and have doveadm use some alternate configuration with zlib_save set? It doesn't look hopeful because I don't see the ability to use a different config at https://wiki.dovecot.org/Tools/Doveadm/Altmove. Perhaps I would need multiple copies of the daemon running? Or is it better just to compress everything? I plan to store older mails (perhaps 3months+) in the alternative storage, and was thinking it would be nice to have those compressed, while I don't need to compress the main store. Any feedback welcome. Thanks, Alex

Re: Changed separator, sub folders not showing new e-mail

I found the answer here: https://apple.stackexchange.com/questions/441313/no-mailbox-doesnt-exist-se… Apparently on Mac one needs to update the separator on a file, since it doesn’t seem that the Mail.app does it for itself. On the iPhone it happened automatically. Best, Francis

Changed separator, sub folders not showing new e-mail
by Francis Augusto Medeiros-Logeay 02 Oct '23

02 Oct '23

Hi, I recently changed the mailbox separator from '.' to '/' so that I could have shared mailboxes working. However, while the mailboxes show fine on Roundcube and on other web-based e-mail clients, on the Mail.app on my Mac I don't get newer messages on those sub folders. For example, I have a subfolder Test. Mails filtered to be dropped there, show fine. But I have one called Lists, with a sub folder called "Dovecot". I can't read mails that are under "Lists/Dovecot". Can anyone help? Best, Francis -- Francis Augusto Medeiros-Logeay Oslo, Norway

Hi Martin, I had a similar problem: https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/DNHM3… It seemed to me that using ‘.’ truncated the domain name when that was used in the paths, such as when using %d. Best, Francis

Re: Dovecot lda-dupes
by Francis Augusto Medeiros-Logeay 28 Sep '23

Hi, I have read elsewhere that the Maildir shouldn’t be at the home. But that’s how it worked for me since the start. I wonder if I could either change the location of these .dovecot.lda-dupes, or if I could change home without having to move the mailboxes of all the users. Today I have this: On my dovecot-sql.conf.ext: iterate_query = SELECT username AS user FROM mailbox user_query = SELECT CONCAT('/var/mail/vmail/',maildir) AS home, \ CONCAT('maildir:/var/mail/vmail/',maildir,':INDEX=/var/vmail-index/index/%d/%n:CONTROL=/var/vmail-index/control/%d/%n') AS mail, \ 5000 AS uid, 5000 AS gid, CONCAT('*:bytes=',quota) AS quota_rule \ FROM mailbox WHERE username = '%u' AND active = 1 password_query = SELECT username AS user,password FROM mailbox \ WHERE username = '%u' AND active=‘1' On my 10-mail.conf mail_location = maildir:/var/mail/vmail/%d/%n:INDEX=/var/vmail-index/index/%d/%n:CONTROL=/var/vmail-index/control/%d/%n If I add `Maildir` to the mail_location and to the mail user_query, will I have to move mailboxes, or the only thing I have to do is to add “Maildir” when I use %h/%%h? Best, Francis
