Hi Aki, first thanks for the quick fix. Unfortunately, it only resolves the issue partially. For the ?To: undisclosed-recipients:;?, it works now. For ?To: ? it still crashes (i. e. what I did with my manual lmtp dialog). Michael > On 13.

Hallo Aki, the affected code location seems to be concerned with parsing to ?To:? header. I checked all the mails causing the crash, the To: header is either empty (but present) or contains ?undisclosed-recipients:;?. I checked this manually and sure enough lmtp crashes: nc -C -U dovecot-lmtp 220 keira.mike2k.de Dovecot

Hello, since the upgrade from 2.3.8 to 2.3.9 (using the Ubuntu 18.04 packages from dovecot.org), lmtp crashes for me for some mails. Currently I have three pending mails in my postfix deferred queue since the upgrade a couple of days ago. I did not observe these issues with 2.3.8. The backtrace from one of the coredumps: Reading symbols from /usr/lib/dovecot/lmtp...Reading symbols from

Hello, I am using Dovecot 2.2.19 with the solr backend for full text search and experience the following issue. When I issue a search that includes characters that are part of lucene's query syntax (e.g. the double quote character), dovecot does not escape the special characters and issues a request with invalid syntax to the solr server. For example, I search for foo"bar, then

Hi, Our setup: - 4 hosts with director and mailbox instance - delivery via director lmtp into mailbox lmtp - mailbox format: mdbox - storage on NFS - OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS - Dovecot 2.1.10 - Pigeonhole 0.3.3 We're getting strange "out of memory" lmtp errors/backtrace with dovecot 2.1.10 accompanied by high load caused caused by a lot of lmtp

Hi, I am using dovcot on a Fritz!Box (Linux fritz 2.6.19.2 #1 Fri Apr 18 16:00:34 CEST 2008 mips unknown) And after upgrading from 1.0.9 to 1.0.15 I am getting above assertion, when I do some action like moving or deleting on the IMAP mail box using MailDir on ext2 fs. I use --with-ioloop=epoll and --with-mem-align=4 as build configuration. For dovecof configuration see below details. Thanks

Hi, I'm using dovecot 2.0.13 that ships with Ubuntu 11.10. I tried setting up a shared namespace as documented in the wiki to enable the sharing of a mailbox between two users. I have a Maildir(++) directory for each user. Each user has a system account. The Maildir of each user is owned by the user's system account and group read/writable by the group mail (hence

Hi everyone, I feel like I am missing something obvious here. I have dovecot up and running and every piece of mail is given user read/write permission. I see the option mail_gid, but I do not see anyplace to set the group permissions. I see the below wiki talking about new home directories getting their permission from the parent directory, but this does not seem to work. Any

I'm trying to set up dovecot on a Fedora box for about 5 users, I have a raid 5 array that is used for home folders etc mounted on /home, and I've created a directory /home/mail, which I have used a sym link to map /var/mail to. I've created folders for each of the users with relevant permissions and edited the dovecote config with:- namespace private { separator = / prefix =

Hello, as I need to store a lot of messages on my IMAP server (order of 900K-1000K; this is an archive for some time, maybe a year or so), I see some "slowness" in dealing with such a huge amount. I mainly need to do searches like "get all messages from user1 at domain1.com to user2 at domain2.tld recieved between date1 and date2". So I really interested will it be wise

Hello Dovecoters, I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4 When I backup mdboxes (using SIS) using this command doveadm -Dv -o plugin/quota= sync -1f -u user1 at user.com mdbox:/mailbackup/user1 mails get backedup but all m files are not copied. Last file copied is m.4 If I run the command again I get below error I tried with doveadm backup command as well (many times).

Hello, We are deploying shared mailboxes in our mail system. We are running 2.1.9 and mail backend is maildir. As described at http://wiki.dovecot.org/SharedMailboxes/Shared when shared namespace is configured as namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } each user

OK, gurus, I've spent the last 2 days crawling through all of the posts and web postings regarding shared folders, and I simply cannot get it to work. I'm sure that there is something simple that I've overlooked, but cannot for the life of me see it :) Here's my current config: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-46-generic x86_64 Ubuntu
