Mail with single \r, partial fetch, error "Broken virtual size in mailbox"
by Ewald Dieterich 17 Jan '25

17 Jan '25

I run Dovecot 2.3.21 with the mdbox mailbox format. If I do a certain partial fetch on a mail with a single carriage return \r Dovecot closes the connection and logs the following error: Error: Mailbox INBOX: Deleting corrupted cache record uid=1: UID 1: Broken virtual size in mailbox INBOX: read(/var/spool/dovecot/user/storage/m.1): FETCH BODY[]<18.100> got too little data: 5 vs 6 This happens every time, doveadm force-resync doesn't help. Here's how to reproduce the issue: Deliver a mail with a single carriage return \r (here after the header/body separator, but that's not important): echo -ne "Subject: Test\r\n\r\n\rBody\r\n" | doveadm save -u user Then do a partial fetch from a specific offset: . fetch 1 body[]<18.100> * 1 FETCH (BODY[]<18> {6} ody Connection closed by foreign host. Offset 18 with length 6 should "Body\r\n", that's why the response is 1 byte short ("got too little data: 5 vs 6" in the error message), by why is \r causing this? Other offsets seem to work.

How should I use 'doveadm search -u' to get the mailbox path where the message is stored?

Problem email client iPhone ios18.2
by andrzej.milewski＠gmail.com 11 Jan '25

11 Jan '25

Hello, I have a fairly new installation of the Dovecot server version 2.3.19.1 on Debian 12.8. In general, the server works correctly. It sends and receives emails without issues. The clients primarily use Thunderbird on desktops and Gmail on Android. However, some clients are using iPhones with various hardware versions. Those with iOS below version 18 work correctly without any issues. Those who have updated their phones to version 18 and now even 18.2 are experiencing problems with mailbox synchronization. On version 18.2, the issue appears as follows: When you open the app, you can read several messages. They load correctly, but, for instance, attachments do not. If I wait for some time, the attachment eventually loads. During this time, I observe the server logs, and it shows that a certain session on the Dovecot server has ended.

From the logs and router analysis, it appears that the download happens in another previously opened session. After this incident, I go to another message with an attachment, and the situation repeats. There are also situations where the email body does not load, and the app waits for the server until the session closes and the content is fetched in another session. It does not matter whether I connect to the server via the internet or through a local network. On an iPhone 7 with iOS 15.8.3, everything works smoothly. Attachments open without issues. On iOS 18.1.1, attachments do not load, and the session does not close on its own. It takes forever unless the app is closed. In the Gmail app, everything works correctly without any issues. This is clearly a problem with the mail client on iPhone. However, is there anything I can adjust in my server settings to mitigate this issue for users?

Bug report on attachment search in dovecot fts plugin
by h.murakami＠lab8.co.jp 10 Jan '25

10 Jan '25

Hi. I am using dovecot's fts plugin and have found a bug-like behavior. I have confirmed that dovecot by itself with fts plugin disabled works fine. dovecot --version 2.3.19.1 (9b53102964) The pattern we found is as follows 1. search with `with attachments` condition from RoundCube linked to dovecot 2. dovecot fts plugin executes the following query to solr but no document is found hdr:application%5c%2f+OR+hdr:multipart%5c%2fm+OR+hdr:multipart%5c%2fsigned+OR+hdr:multipart%5c%2freport 3. roundcube search results also show no items found That's all I have to report. If there is any way to improve the situation, we would like to receive it.

repo.dovecot.org status
by Jasper Spaans 06 Jan '25

06 Jan '25

Hello list, We're using the packages from repo.dovecot.org to run the latest version of dovecot on our systems running ubuntu focal (20.04). We'd like to upgrade these to a more recent ubuntu version[1], but those builds are not available on repo.dovecot.org. Is that repo still supported? If so, what would it take to get builds for ubuntu 22.04 and/or 24.04 on there? I can spend some time on that, but I also have the impression that the build infra (including the scripts) that generate the packages for this repo is not very public. Cheers, Jasper [1] for reasons that are out of scope for this message, using a dockerized build or upgrading to 24.04 (which does come with 2.3.21) is not an option at this moment, so we are currently looking at 22.04. unfortunately that also comes with a dovecot from 2022

SCRAM-SHA -PLUS variants and Dovecot (Channel Binding)

Dear all, In first, I wish you a Happy New Year 2025! In the past, I have requested SCRAM support in Dovecot, etc. I would like to know the situation with -PLUS variants (Channel Binding)? This feature for more security is always missing. RFC 9266: Channel Bindings for TLS 1.3: - https://datatracker.ietf.org/doc/html/rfc9266 Little details, to know easily: - tls-unique for TLS =< 1.2 - tls-server-end-point - tls-exporter for TLS = 1.3 Can you add tls-unique, tls-server-end-point and tls-exporter to be perfect? Stephan Bosch has started but no news since one year: - https://github.com/dovecot/core/compare/main...stephanbosch:dovecot-core:sa… Other links: SASL2 I-D: Extensible Simple Authentication and Security Layer (SASL): - https://datatracker.ietf.org/doc/html/draft-melnikov-sasl2 It is in several XEPs too: - XEP-0388: Extensible SASL Profile: https://xmpp.org/extensions/xep-0388.html - XEP-0440: SASL Channel-Binding Type Capability: https://xmpp.org/extensions/xep-0440.html - XEP-0474: SASL SCRAM Downgrade Protection: https://xmpp.org/extensions/xep-0474.html - XEP-0480: SASL Upgrade Tasks: https://xmpp.org/extensions/xep-0480.html Thanks in advance.

Hard-coded upper limit for sieve_max_redirects ?
by Maciej Polewczynski 02 Jan '25

02 Jan '25

Hello, After upgrading Dovecot from version 2.3.4 to 2.3.19 i noticed errors for some users having sieve redirects. Before upgrade all worked fine. In sieve plugin i have two limits: sieve_max_actions = 500 sieve_max_redirects = 150 If user have up to 100 redirects all works fine but if there are 101 or more none of them works and there is error: dovecot: lmtp(test2.mbox) Error: sieve: msgid=<***l>: redirect action: failed to check for duplicate forward to <101th.email.address> It seams that there is another limit but cant find where. When checked "dovecot -n|grep 100" there was only "default_process_limit". Increasing this changed nothing. Still the same error. File ".dovecot.sieve.log" in user home dir don't have any additional information. There is only: redirect action: failed to check for duplicate forward: internal error occurred: refer to server log for more information. Do you have any ideas how to fix it? -- Best regards, Maciej Polewczyński Do or do not. There is no try.

Moving all mail from one user to another
by Peter Reinhold 29 Dec '24

Hi all I have a user that has changed domain, and I am looking to move all her mail from her old account into her new one, but I am really unsure about how to go about it I would think that I am should use https://doc.dovecot.org/main/core/man/doveadm-move.1.html to do it, but the example supplied and all discussion about that tool I can find online is only about moving a users mail across folders on their account, and not the entire accounts content to another account. Has anyone tried to do something like this? -- Peter Reinhold
