Files in tmp directory
by David Morsberger 05 Dec '20

05 Dec '20

I had to restore many thousands of dovecot emails from a crashed Mac Server to a new Ubuntu server. After completing I am noticing a few things that may be okay or may need to be fixed. 1) a couple of mailboxes have a lot (one has 102462) emails in the tmp directory. The files do not have the standard Mairdir++ filename format. An example: 1581262582.M397740P72267.mini.mmpcrofton.com <http://1581262582.m397740p72267.mini.mmpcrofton.com/> (missing the stuff at the end, ,S=,W=:2,S) 2) I see files in the cur directory that do not have the Maildir++ format. An example: 1601287326.V810Ie80087M240104.mmp-mail.mmpcrofton.com:2,S. (do not have the ,S=,W= values and the second value, V810Ie80087M240104, is longer that the other file names) How do I get the emails in (1) out of tmp? Do I need to convert the emails in (2)? David

Combine director and HAProxy for loadbalancig and failover
by Steven Varco 05 Dec '20

05 Dec '20

Hi All I’m trying to achive an active/active cluster with dovecot-director and HAProxy, as the director does not do health checks (loadblancing only) and I want both, loadblancing AND failover, where the latter is far more important to me (loadblancing I would just use as an addon and for curiosity, it is not really need in my setup). However, I’m not sure if this combination can be used that way, as I found almost no documentation on this. What I found is using either directory OR haproxy with dovecot, but not both. So I guess, that the description here is intended to use without the director: https://wiki2.dovecot.org/HAProxy This older list post is basically exaclty, what I’m trying to achive: https://dovecot.org/pipermail/dovecot/2015-July/101487.html Clients --> Load Balancer(HAProxy) --> Dovecot Proxy(DP) --> Dovecot Director(DD) --> MS1 / MS2 As far as I understood, this would require to (statically) set a host= entry for each client which would give another single point of failure? However reading the documentation: https://doc.dovecot.org/configuration_manual/haproxy/ assumes that this setup IS actually possible. Unfortunately it does not describe how dovecot must be setup at this point. So I assume since HAProxy is listening on port 1143 (for IMAP) and dovecot (with directror enabled) is listening on port 143, which is the main entry point for clients. So in this setup dovecot-director should first pass the mail traffic to HAProxy on port 1143 and then HAProxy passes it to the actual imap servers? So how would the dovecot setup on the director servers look like and how on the dovecot imap mail servers? My setup consist of each two machines: loadblancer (with HAProxy and dovecot-director) and dovecot imap servers. Last but not least, I found documentation for „dovemon“, which, if I got that correctly, should replace the external tool „poolmon“: https://doc.dovecot.org/configuration_manual/dovemon/ - However, I could not find out where the configuration YAML file (/etc/dovecot/dovemon.config.yml) should get included in the main dovecot configuration. By default this file would not be included at all and therefore would have no effect… thanks. Steven My setup: LOADBALANCERS: Currently one only running on: 10.0.2.26 haproxy: Exactly as: https://doc.dovecot.org/configuration_manual/haproxy/ where the backend servers line have been replaced with the mail servers. dovecot -n #

Server-side threading
by ohw.giles＠gmail.com 05 Dec '20

05 Dec '20

Hi list, Considering a message A in INBOX, where a reply B is sent and copied to the recipient's SENT folder, and to which a reply-to-reply C is received, again in INBOX, how should the list of threads in INBOX be (ideally) retrieved? Using THREADS=REFS when listing threads in INBOX to avoid matching unrelated threads unfortunately seems to miss the above example because B is only in SENT, not INBOX. REFERENCES allows A to be linked to C, but the sent message is missing from the returned thread. Of course this is by design. When listing messages in a selected mailbox, many modern clients provide the experience of listing the messages grouped by thread, showing all threads where *at least one message in the thread is in the selected mailbox*. IIUC, clients usually build their own indexes to achieve this, which seems wasteful. Does dovecot provide a server-side way to list or search messages and return threaded results in this manner?

Any RPMs for aarch64 available?
by Peter Cooper Jr. 04 Dec '20

04 Dec '20

Hey, I really appreciate Dovecot being available with standard repos in repo.dovecot.org. I'm currently using the "CentOS 7" one on Amazon Linux 2 and it works great for x86_64. I'm wondering if there are any plans for also providing arm builds (aarch64) at some point? Or if they're available somewhere else already? I may play around with compiling things myself, but just downloading an official package is generally the easier way to go so I thought it couldn't hurt to ask. Thanks, Peter

follow up to my mail issues I posted about
by Christy S 03 Dec '20

03 Dec '20

Okay. A few days late, but I've gone through the replies I received from several of you and consolidated responses into one mail. Of course life gets crazy when I need to sit down and work on things. "It seems to me Thunderbird is struggling to write to the Sent mailbox, so disk space, and file permissions are the obvious ones to check. And yes, on the server rather than your local machine, as you're using IMAP" It's definitely not disc space. I wouldn't think an upgrade would change permissions, but it's a place to check. I'm showing my newbieness here but, I'm not even sure what account should have access to those files. I know, it's a miracle I got all this working in the first place. I should have taken notes, but I did so much fiddling with this and that to make it behave that I didn't know what to write down. "Anything interesting in the dovecot logs at the time when you check?" So I looked up dovecot logs on google, and what I'm seeing is that dovecot generally writes to mail logs under /var/log. The stuff I sent in my first email came from mail.err in that folder. The only other file I could find was mail.log. Using tail on that file, I see entries like these. Dec 2 20:53:07 kylesmith-music postfix/smtpd[396853]: warning: unknown[212.70.149.37]: SASL LOGIN authentication failed: UGFzc3dvcmQ6 Dec 2 20:53:07 kylesmith-music postfix/smtpd[396853]: disconnect from unknown[212.70.149.37] ehlo=1 auth=0/1 rset=1 quit=1 commands=3/4 There are similar entries from a different ip address, but interestingly neither match the ip address of our fiber modem so I have no idea what's going on there. "First, do you have a backup prior to upgrading the server? You may want to refer to that to get a clean idea of how the configuration was set up initially. Sometimes the upgrade process can reset configuration files and its usually easier to work from a known working configuration. " I really wish I did, but I'm not sure how to effectively back up a VPS. "Second, can you describe how you set the mail stack you are using up?" I can tell you it's postfix and dovecot. That's what a lot of articles recommended, so I went with that. We use different devices so I chose to use imap as it interfaces directly with the stored mail on the server. Usually this is good, except now when it breaks. "Its possible the issue is SSL related but its difficult to say. There have been a number of breaks with SSL encryption in recent years which is why the cipher list has been adjusted," SSL is definitely my weakest point of knowledge. I know I had it working smoothly but it was basically following how to stuff. The reason we're using it even for mail has to do with someone in my husband's life who would get in and mess things up if he had the chance, so I'm trying to make sure he doesn't have that chance by locking things down tight. "google can also be out of date I'd recommend using a date filter when using it for checking configurations and limit it only to the last 1-2 years as you will get more relevant information typically." Oh my gosh, that alone would be extremely helpful. The number of seriously outdated articles I had to filter through when I set this up in the first place is just unreal. Mind telling me how to do a date filter? Otherwise, I'll google how to use google, hahaha. "The configuration parameter for the cipher list uses HIGH as a default profile and if I recall correctly that disables lower TLS versions that are susceptible to certain types of attacks. (SSL3,TLS1,TLS1.1,1.2 I think) The dovecot documentation explains what the defaults are for HIGH. The ! prevents using specifica protocols and configuration is usually a chain (processed from left to right until a match is found). DH is the diffie-helman exchange. Usually this file is recalculated on a per server basis to prevent pre-calculation attacks on SSL and usually it must meet a certain key length. DH Groups 1 and 2 are known to be insecure." Okay, that went way over my head, but it sounds like good information to have and study up more on, hopefully after I get the immediate issue solved. If I'm following you correctly at all though I could see that potentially being my issue, hmm. I will for sure see if I can get my hands on that book. "Some quick thoughts here — if the changes you mentioned did not solve the issue, I would definitely comment those back out so you are only troubleshooting one thing at a time." Fair point. I commented out the one about dh high, then hopefully reloaded the configuration, dovecot reload? That done, I tried sending an email from the domain to my gmail using thunderbird. I got the same message, but it did actually send this time. However, when I replied to the test message with my gmail account, it wasn't received by thunderbird. I do see it using the mail app on the server, though. "Next, are you able to send email using any other client?" I can send mail locally on the server from one account to another for sure. I managed it once, at least. Those mail clients seem clunky though so I may not be doing things correctly to test. "Third, try disabling all SSL and see if you are able to send via Thunderbird or really, any client at all…" Is there an easy way to disable ssl for now and then reenable it? That would definitely help narrow this down. "Your DH parameters are too weak. You should generate at least 2048 byte parameters." To be honest, I don't even recall setting up DH parameters. I would guess that probably happened when I was setting up ssl? Again, thank you to each of you for helping with this. I really try not to send stuff like this to mailing lists that are technical in nature, but this is important business mail he's potentially missing and I'm a bit out of my league. First project once this gets fixed will be learning how to back up the server. Christy

Meanwhile, I also found the fix from October. I can confirm that the issue occurred on 2.3.11.3 only. I switched to the previous version (which is pretty easy thanks to Docker) and the issue disappeared. All messages were indexed properly afterwards. I applied the fix and will observe it for the next couple of days. The assertions have been misplaced anyway from my viewpoint because the asserted fields (or properties or whatever, I don't know how they're called in C) are not accessed in every case. I am happy that this is scheduled for 2.3.13. Although, I hope that the payload_input or payload_output won't be NULL when payload_finished is true. :) Thanks a lot to you guys for all the effort. I would not be able to resolve this on my own without your help. Best, Manuel

I thought that if Dovecot sees broken X-UID headers for "new" messages, they're silently fixed? Can you tell how I can correct this error/warning? Thanks! BR, Jos
