2.4 crashing on macOS with time moving forward?
by John Muccigrosso 02 Mar '25

02 Mar '25

After last week's struggle with the new version and my conf file, I got everything working. Now however dovecot crashes on me every few hours. The logs show a bunch of this kind of warning, which I find mention of on the internets: > Feb 07 15:13:47 imap(58317): Warning: Time moved forward 48.803640 seconds > Feb 07 16:30:27 master: Warning: Time moved forward by 694.039203 seconds - adjusting timeouts. > Feb 07 16:52:47 imap(61246): Warning: Time moved forward 293.443011 seconds > Feb 07 16:52:47 master: Warning: Time moved forward by 1279.423507 seconds - adjusting timeouts. > Feb 07 17:25:39 imap(61286): Warning: Time moved forward 1942.575589 seconds > Feb 07 17:25:39 imap(61288): Warning: Time moved forward 172.563346 seconds > Feb 07 17:25:39 master: Warning: Time moved forward by 1912.666999 seconds - adjusting timeouts. > Feb 07 17:49:32 imap(61286): Warning: Time moved forward 1402.761862 seconds > Feb 07 17:51:13 master: Warning: Time moved forward by 1473.582569 seconds - adjusting timeouts. > Feb 07 17:51:13 imap(61286): Warning: Time moved forward 70.823888 seconds > Feb 07 17:53:07 master: Warning: Time moved forward by 53.843767 seconds - adjusting timeouts. > Feb 07 18:44:22 imap(61286): Warning: Time moved forward 1386.259444 seconds > Feb 07 19:11:41 master: Warning: Time moved forward by 615.609964 seconds - adjusting timeouts. Note the very large jump dovecot claims is happening in all of these, up to half an hour, with a minimum of 48 seconds in this bunch. You can see that it even does a pair of these in rapid succession, like at 17:25:39 above, and will do >10 within the space of an hour. These seem eventually to be followed by a crash ("eventually" because I'm running this on my laptop which isn't always open and running). The crash log entries all start with something like this: > Feb 07 16:17:53 imap(58315): Panic: file ./time-util.h: line 40 (timeval_add_usecs): assertion failed: (usecs >= 0) The reports will end with one of these: > Feb 06 17:45:07 log(48089): Warning: Killed with signal 15 (by pid=1 uid=0 code=unknown 0) > Feb 07 16:17:53 imap(58317): Fatal: master: service(imap): child 58317 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) One more detail, I usually do `sudo brew services start dovecot` to run dovecot and this results in the crashes. When I was testing this on Saturday, I started it with `sudo dovecot -F` instead, so that I would see problems in the terminal. It went all day without crashing and I finally stopped and restarted it with the brew method. That's not a rigorous test, but it is suggestive. Happy to provide more info, but I'm hoping this is sufficient to suggest a course of action. dovecot 2.4.0 installed via homebrew macOS 13.6.9 J

Pigeonhole: sieve_redirect_envelope_from orig_recipient results in mail bombs
by doobry 28 Feb '25

28 Feb '25

Dear Dovecot community, we changed `sieve_redirect_envelope_from` to `orig_recipient` recently to fix sieve redirects in case the forwarded mail comes from a DMARC-enabled domain. While this works well, it creates a new problem: if the receiving mail server (the one in charge of the redirect destination) reacts with a bounce mail, the bounce now will go to `orig_recipient` - the mail address that has the redirect in place, which means no less than creating a mail bomb (endless mail loop). See the following example: 1. alice(a)sender.org sends mail to jane(a)our-domain.org 2. jane(a)our-domain.org has a sieve redirect to jane(a)redirect-target.org 3. jane(a)redirect-target.org replies with a bounce because their mailbox is full. 4. The bounce mail gets sent to jane(a)our-domain.org. 5. The loop starts again at step 2. Is it possible to configure dovecot/pigeonhole to *not* forward the bounce mails from step 4 again? Probably it would work to add manual extra checks to the sieve redirect rules, but that would need to be followed by any user who configures a redirect. So I'm more looking for a server-wide configuration change that fixes this problem. Looking forward to hear about your thoughts on the problem. Kind regards doobry

Dovecot 2.4.0 multiple hosts SNI configuration regression
by Julius Kriukas 27 Feb '25

27 Feb '25

Hello everyone. We are testing out Dovecot 2.4.0 and noticed a regression in how the `local_name` filter with multiple space-separated host names works. For example, having the following dovecot.conf: ``` ... ssl_server_cert_file = /etc/dovecot/global.cert ssl_server_key_file = /etc/dovecot/global.key ssl_server_dh_file = /etc/dovecot/dh.pem ... local_name "server.example.com mail.example.com" { ssl_server_cert_file = /etc/dovecot/example.com.cert ssl_server_key_file = /etc/dovecot/example.com.key } local_name "good.example.org" { ssl_server_cert_file = /etc/dovecot/example.org.cert ssl_server_key_file = /etc/dovecot/example.org.key } ... ``` Connection to server.example.com:993 (with SNI support) does not work as expected. The global certificate from the `global.cert` file is used, and validation fails. However, connection to good.example.org:993 (with SNI support) works fine. The `example.org.cert` file is used. The `doveconf` tool thinks the example configuration should work, hinting that this is likely to be a bug. Example: ``` # doveconf -f local_name=mail.example.com ssl_server ssl_server { cert_file = /etc/dovecot/example.com.cert dh_file = /etc/dovecot/dh.pem key_file = /etc/dovecot/example.com.key } ``` The results show correct file paths, but the `dovecot` server is not using them. Any confirmation if this is really a bug, or maybe an intended configuration syntax change (to force repeating the local_name blocks for each hostname) would be really appreciated. Thanks. -- Julius

Issue with ACLs in Dovecot 2.4
by Andrea Gabellini 27 Feb '25

27 Feb '25

Hi, I'm trying to migrate my setup to Dovecot 2.4, but I'm experiencing an unusual issue with ACLs. After multiple tests, I’ve stripped the configuration down to the bare minimum to pinpoint the root cause of the problem. Basically, if I set "owner lr" as the permissions for a folder, I am unable to move any messages, yet I can still create subfolders. Here’s the relevant configuration: ini Copia Modifica protocol imap { mail_plugins { acl = yes } } acl_driver = vfile acl_globals_only = yes namespace inbox { inbox = yes separator = / mailbox Test { acl owner { rights = lr } } } Am I missing any configuration, or have I encountered a bug?

Strange problem with iPhone Mail
by Simon Hoffmann 27 Feb '25

27 Feb '25

Hey list, I am experiencing a strange problem where I don't even know where to begin to debug. I am running my own email server in my office. The server itself works fine. In my office firewall, I have set up DNAT/port forwarding to be able to access the server from outside. With my Android phone and my iPad I have no problems accessing the mails from anywhere, including my home WiFi. However with my iPhone, I have problems accessing my inbox when I am on my home WiFi. The problems only started a few weeks ago, it worked fine for years before. I have not changed any network related settings. Now, when I am on my home WiFi, I cannot use the "pull down to refresh" gesture. It just is not fetching any emails. The automatic sync/fetching is also not fetching the newest emails. Eventually, some emails will come through, but they are from ~6-7 hours ago. Same WiFi as my other devices that work fine. As soon as I disable WiFi on my iPhone and switch to mobile data and do the "pull down to refresh" gesture, all mails from the last 6-7 hours immediately come in. Has anyone ever experienced something like this and can help me analyse the problem? root@mx01:~# uname -a Linux mx01 5.10.0-33-amd64 #1 SMP Debian 5.10.226-1 (2024-10-03) x86_64 GNU/Linux root@mx01:~# cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 11 (bullseye)" NAME="Debian GNU/Linux" VERSION_ID="11" VERSION="11 (bullseye)" VERSION_CODENAME=bullseye ID=debian HOME_URL="https://www.debian.org/" SUPPORT_URL="https://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/" root@mx01:~# dpkg -l dovecot* ||/ Name Version Architektur Beschreibung +++-======================-========================-============-=============================================== un dovecot-abi-2.3.abiv13 <keine> <keine> (keine Beschreibung vorhanden) un dovecot-common <keine> <keine> (keine Beschreibung vorhanden) ii dovecot-core 1:2.3.13+dfsg1-2+deb11u2 amd64 secure POP3/IMAP server - core files un dovecot-gssapi <keine> <keine> (keine Beschreibung vorhanden) ii dovecot-imapd 1:2.3.13+dfsg1-2+deb11u2 amd64 secure POP3/IMAP server - IMAP daemon un dovecot-ldap <keine> <keine> (keine Beschreibung vorhanden) ii dovecot-lmtpd 1:2.3.13+dfsg1-2+deb11u2 amd64 secure POP3/IMAP server - LMTP server un dovecot-lucene <keine> <keine> (keine Beschreibung vorhanden) ii dovecot-managesieved 1:2.3.13+dfsg1-2+deb11u2 amd64 secure POP3/IMAP server - ManageSieve server un dovecot-mysql <keine> <keine> (keine Beschreibung vorhanden) un dovecot-pgsql <keine> <keine> (keine Beschreibung vorhanden) un dovecot-pop3d <keine> <keine> (keine Beschreibung vorhanden) ii dovecot-sieve 1:2.3.13+dfsg1-2+deb11u2 amd64 secure POP3/IMAP server - Sieve filters support un dovecot-solr <keine> <keine> (keine Beschreibung vorhanden) un dovecot-sqlite <keine> <keine> (keine Beschreibung vorhanden) un dovecot-submissiond <keine> <keine> (keine Beschreibung vorhanden) Thanks!

Thunderbird IMAP Problem
by wertstoffe＠nurfuerspam.de 26 Feb '25

26 Feb '25
