expunge not removing attachments?
by Ralf Hildebrandt 12 Feb '19

12 Feb '19

I have a large mail backup folder backup(a)backup.invalid; I'm cleaning up daily like this: infimum=`date -d "-4 day" +"%Y-%m-%d"` doveadm expunge -u backup(a)backup.invalid mailbox INBOX SAVEDBEFORE $infimum doveadm purge -u backup(a)backup.invalid yet I see this: # find attachments/ -type f -ctime +5 | wc -l 7522 # find attachments/ -type f | wc -l 127579 # find attachments/ -type f -mtime +5 | wc -l 14361 # find attachments/ -type f | wc -l 127793 About 5.9% of the files in attachments and below are older than 5 days. Why? Is that normal? using dovecot 2:2.3.1-1 from the official repos. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | https://www.charite.de

SELinux policy to allow Dovecot to connect to Mysql
by Robert Moskowitz 05 Feb '19

05 Feb '19

As I have noted in previous messages, I been getting the following on my new mailserver: Apr 7 10:17:27 z9m9z dovecot: dict: Error: mysql(localhost): Connect failed to database (postfix): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) - waiting for 25 seconds before retry They go away when I setenforce 0. It is not a timing issue as I earlier thought. So I googled dovecot mysql selinux and the only worthwhile hit was: http://zszsit.blogspot.com/2012/12/dovecot-mysql-selinux-issue-on-centos6.h… that provides a /etc/selinux/dovecot2mysql.te and other selinux stuff. Is there a simpler way like a setsbool option? With all the howtos on dovecot with mysql, it is interesting that none of them seem to have this problem. Maybe because they connect to mysql through TCP port 3306 which has ITS set of problems (like MariaDB defaults to not listening on TCP). thanks!

auth: Error - Request timed out
by Hajo Locke 01 Feb '19

01 Feb '19

Hello List, i use dovecot 2.2.22 and have the same problem described here: https://dovecot.org/pipermail/dovecot/2017-November/110020.html I can confirm that sometimes there is a problem with connection to mysql-db, but sometimes not. Reasons for failing are still under investigation by my mates. My current main problem is, that this fail seems to be a one way ticket for dovecot. Even if mysql is verifyable working again and waiting for connection dovecot stucks furthermore with errors like this: May 29 07:00:49 hostname dovecot: auth: Error: plain(mail(a)example.com,xxx.xxx.xx.xxx,<HGI4FVFt2Oy80j3P>): Request 999.7 timed out after 150 secs, state=1 When restarting dovecot all is immediately working again. Is there a way to tell dovecot to restart auth services or reinitialize mysql-connection after these hard fails? I could insert "idle_kill = 1 mins" into service auth and service auth-worker, but i dont know if this would work. Unfortunately i am not able to reproduce this error and there are always a couple of days between errors. Thanks, Hajo

Dovecot Submission Proxy Auth
by Paul Hecker 12 Jan '19

12 Jan '19

Hi, Dovecot 2.3.1 (8e2f634). Could not get Dovecot to forward the (plain) authentication to the SMTP server using submission. Reason why I need it is sender spoofing (do not want my employees to send messages in behalf of me). In exim I can disable sender spoofing with the authenticated user. When sending through dovecot, exim either does not accept the email (need auth) or relay every sender address (because relaying from localhost). Am I missing a setting or do I need any additional field in the (MySQL) user_query/password_query to forward the password? You can find my config here: https://gist.github.com/lluuaapp/7daddf761131da47237b0f45e6bab5a8 Thanks, Paul

Hello! dsync SSL still doesn't work for replication, so I've disabled it and tried to sync without. But I have a problem with temp directory. Is it possible to change path to temp folder?

outlook idiocy - IMAP folders with /
by Wojciech Puchar 20 Dec '18

20 Dec '18

user attempts to create folders with / dovecot naturally cannot create it so it returns error but outlook of course "create" it and keep data in local store only. data is lost when you remove local store .pst file. The question is - can dovecot be configured so it will automatically replace slash in name with something else?
