Hi experts. in the output of imapsync I found: Host2: found quota, presented in raw IMAP Sending: 7 GETQUOTAROOT INBOX Sent 22 bytes Read: * QUOTAROOT INBOX "User quota" * QUOTA "User quota" (STORAGE 420325 1953125) 7 OK Getquotaroot completed (0.001 + 0.000 secs). Host2: Quota current storage is 430412800 bytes. Limit is 2000000000 bytes. So 21.52 % full Host2 is under my control and running dovecot-2.3.10.1. I need to increase the quota above 2 GB but don't know where it comes from and therefor don't know what to do.

Mail replication fails between v2.2.27 and v2.3.4.1
by Apostolis Hardalias 03 Jul '20

03 Jul '20

Hello, I have two installations of dovecot configured to replicate mailboxes between them. recently, i upgraded the operating system on one of them (mx2.example.com) and now i'm running one installation on version 2.2.27 (debian stretch) and another on version 2.3.4.1 (mx1.example.com debian buster). My setup includes 3 shared namespaces that point to the mailboxes of 3 accounts. these accounts are setup to use maildir format. After upgrading one of the hosts, i started having issues with failed replications on those mailboxes. I tried running the replication manually and repeatedly by issuing the following on mx1.example.com: doveadv -d sync -u exception_bucket(a)example.com -d -l 30 -n -u and the logs on mx2.example.com included the following lines consistently: Jul 02 14:21:58 dsync-server(exception_bucket(a)example.com): Debug: brain S: Change during sync: Mailbox GUID 2d32711ddfd27250390e0000a712b6e3 was lost Jul 02 14:21:58 dsync-server(exception_bucket(a)example.com): Debug: brain S: We don't have mailbox 2d32711ddfd27250390e0000a712b6e3 I double checked for the existance of the mailbox with that guid (that guid points to the inbox) and the mailbox existed on both servers but, the contents of the mailbox on the two servers where different (missing e-mails on both servers). I attempted running a force-resync command as follows but with no luck. doveadm -d force-resync -u exception_bucket(a)example.com inbox but the issue persisted. admittedly, i didn't run the command on both servers because i read it doesn't replicate after figuring a workaround. The next thing i tried was attempting replication without the -n flag, given that you mention that there are some issues replicating shared namespaces. That didn't fix the replication status either. After looking around, i came onto the solution on this thread: https://dovecot.org/pipermail/dovecot/2017-october/109620.html which proposed setting mailbox_list_index = no. This was the default setting on version 2.2.27, so i changed that setting on mx2.example.com which was running version 2.3.4.1. This allowed the replication to work but i don't think it is a setting i want in my configuration. Is there something i can do to re-enable dovecot to check index files instead of mailboxes? Could that be an issue when replicating between those two different versions? I'm attaching the configuration files for both the mailservers, a separate configuration file is included since mail_replica settings are set from there, and a link to the compressed log file i pulled during the operation. https://filebin.net/d9yygnq8jg74unwb/replication_debug.log.bz2?t=vv2o81ka Thank you in advance, Apostolis Hardalias

local stanza only generated for IPv6
by Jeremy Ardley 02 Jul '20

02 Jul '20

I have a mail server with multiple IP addresses and associated DNS names In the dovecot configuration I have a listen directive: listen = mail.example.com.com,mail.otherexample.com,localhost Multiple local stanzas are of the form: local mail.example.com { protocol imap { ssl_cert = </etc/letsencrypt/live/mail.example.com/fullchain.pem ssl_key = </etc/letsencrypt/live/mail.example.com/privkey.pem service imaps_login { inet_listener imaps { address=mail.example.com } inet_listener imap { address=mail.example.com } } } } mail.example.com has IPv4 and IPv6 addresses in DNS When I run doveconf -n the local configuration is only generated for the IPv6 address. I can test the operation on IPv6 using openSSL and see different server certificates on different IP addresses as expected. How do I force local generation for both IPv4 and IPv6 ?

dovecot: doveconf: Fatal: block_alloc(134217728): Out of memory
by Brent Clark 30 Jun '20

30 Jun '20

Good day Guys Currently on Debian Stretch (2.2.27). This morning we enabled SNI for our clients (file per domain). On going live with the new server configuration, we started getting the following on our shared hosting servers. Jun 30 07:25:04 REMOVED_HOSTNAME dovecot: doveconf: Fatal: block_alloc(134217728): Out of memory Jun 30 07:25:04 REMOVED_HOSTNAME dovecot: config: Fatal: block_alloc(134217728): Out of memory Jun 30 07:25:04 REMOVED_HOSTNAME dovecot: config: Fatal: master: service(config): child 64008 returned error 83 (Out of memory (service config { vsz_limit=512 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) Jun 30 07:25:34 REMOVED_HOSTNAME dovecot: doveconf: Panic: data stack: Out of memory when allocating 2147483688 bytes Jun 30 07:25:37 REMOVED_HOSTNAME dovecot: config: Panic: data stack: Out of memory when allocating 2147483688 bytes This is a server with 2414 domains. On a few of our servers, to buy time, we had to set: default_vsz_limit =10096M A question I would like to ask is. Based on the following change notice, could the following be the problem. https://dovecot.org/pipermail/dovecot-news/2019-July/000412.html - config: Memory leak in config process when ssl_dh setting wasn't set and there was no ssl-parameters.dat file. This caused config process to die once in a while with "out of memory". If anyone could provide any assistance or share a tip on where we can look it would be appreciated. This one has my team and I stumped. Kind regards Brent Clark

POP3Deleted flag issues
by Justina Colmena ~biz 29 Jun '20

29 Jun '20

Hello, I have been running my own mail server with Dovecot, Postfix, and Cyrus-SASL for authentication. = dovecot22u.x86_64 1:2.2.36.4-1.el7.ius @ius I am basically trying to tune the system for better performance. The flat files "/var/mail/justina" etc exhibit locking issues and conflicts when fetching mail at the same time new mail is being delivered by Postfix. Other mail is stored in "Maildir" type folders accessible via IMAP. These exhibit better performance with finer grained locking. There's an "idea" that was posted to the list 7 years ago, shows up top rank on Google. https://dovecot.org/pipermail/dovecot/2013-May/090114.html I fear either an incomplete implementation of the feature or "here-be-dragons" code that may or may not be completely documented. I would like all the "$POP3Deleted" mail to be moved to an "Archive" Maildir folder accessible via IMAP. How do I accomplish this? -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

layout:fs info
by Stefano Gatto - Fly2Net sas 28 Jun '20

28 Jun '20

Hi all, my dovecot version is 2.2.13, quite standard configuration. Can I add directive LAYOUT=fs in dovecot configuration without losing all my archived messages? This should modify the separator of email folders from dots to slashes, correct? BR Stefano

Plugin ABI compat between v2.3.8 and v2.3.9
by Alexander Strasser 24 Jun '20

24 Jun '20

Hi all! This is my first post on this list. Please pardon me if I overlooked or misunderstood some things. I had some imap crashes (sig11) starting at the end of 2019 after an upgrade of dovecot. I found out, that I didn't have any problems using version v2.3.8, but any version v2.3.9 and higher would trigger the crashes. After investigating more deeply and creating a core dump, I saw that the crash happened in an external plugin fetchmail_wakeup[1]. After recompiling that plugin with up to date dovecot headers, I didn't get crashes anymore. So I suspect there were ABI incompatible changes and it was forgotten to bump the minimum Plugin-ABI version supported. I could try to follow up some more details, but it would be quite a burden because of rebuilding the plugin with debug symbols against version 2.3.8 of dovecot and triggering the crash etc. Despite that I think it should be possible to detect changes that are ABI incompatible, as otherwise plugin users would always have to find out first hand with unknown consequences. That said there could be a possibility of the plugin using the API/ABI in an invalid way. If that was the cause, then the plugin should be changed. Hope this report turns out to help improve the situation. I don't have problems currently and will in future be sensitive to this specific possible cause of problems, but not having such crashes in the first place, would be worth it and maybe could still help others. Best regards, Alexander 1: slightly reduced version of: https://github.com/marschap/fetchmail_wakeup

Converting dot-namespaced Maildir to /-namespaced
by Guido Goluke, MajorLabel 24 Jun '20

24 Jun '20

I have a couple of domains on my server, all of them namespaced with a dot. It's 10-15 mailboxes at the most. Is there good way to convert them to / (slash) namespaced folders? Maybe some bash script lying around somewhere?

dovecot fts configuration without solr
by Danilo Tomasoni 24 Jun '20

24 Jun '20

Hello All, I always used dovecot and I'm pretty happy with it, but recently I changed OS (to ubuntu 18) and to get dovecot LTS with lucene (the default I was using on my previous arch installation) I needed to build from source the version 2.3.10 (the one that came with the repos was older and clucene was not actually supported) The problem is that the Clucene is not behaving well, It indexes only some mails but definitely not all according to my tests (there are also strange assertion errors in the logs) I also tried xapian fts index but is very slow indexing and definitely doesn't seem to work. The problem with solr fts is that solr doesn't even start on my tiny system (odroid C2 with 2GB RAM) and anyway I don't want to bloat all the system for the indexing if possible.. Anyone can suggest me a proper minimal and working configuration? Thank you Danilo
