autoexpunge=30d does not works :(
by Peter Hodur 16 Dec '16

16 Dec '16

Hello, just upgraded to Dovecot 2.2.27 and altered dovecot.conf to contain autoexpunge directive for Spam mailbox (yes it's migrated from Courier 3 years ago): namespace inbox { prefix = INBOX. separator = . inbox = yes mailbox Archive { auto = subscribe special_use = \Archive } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Spam { auto = subscribe special_use = \Junk autoexpunge = 30d } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } } As I hope, when user logout (POP3 or IMAP) or after Postfix delivers mail via LMTP, Dovecot should check Spam folder for emails, which have ctime older than 30 days and deletes this emails. Recently I have tried this. I have tried login / logout and nothing happend. I have tried turning log verbosity to debug but I can not find any note in debug.log according to this. I would like to kindly ask someone for which this directive works to help me, what is wrong with my config or how can I debug it and find error. Thanks Pete

Possible solr and indexing bug
by Netfront Customer Service 16 Dec '16

16 Dec '16

Bug Report: We had one of our solr server down for a while, then observed a lot of "Warning: fscking index file " actions. Version 2.2.27 with auto fsck. A follow up investigation shows direct one to one relationship between solr error and subsequent fscking. The fscking lasts for quite a long time (for at least an hour) when the mailbox is concurrently accessed. Thank you.

Configuration problem for secure virtual server
by Karsten Malcher 15 Dec '16

15 Dec '16

Hello, i want to configure a virtual mailsystem on an debian server with exim and dovecot. Because it is running on a V-Server, i want to store everythink in a LUKS encrypted contrainer. So i created a group crypt with the members Debian-exim (107), dovecot, (other users with encrypted content) All mails should be stored in /mail in the mounted container. Dovecot has this configuration: ======================================= passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = static args = uid=Debian-exim gid=mail home=/mountpoint/mail/%d/%n } mail_uid = Debian-exim first_valid_uid = 107 last_valid_uid = 107 first_valid_gid = 8 last_valid_gid = 9 mail_location = maildir:/mountpoint/mail/%d/%n ======================================= The /mountpoint has the following rights: drwxrwx--- 5 root crypt 4,0K Dez 13 19:05 mountpoint The subdirectories are all owned by Debian-exim: drwxrwx--- 4 Debian-exim mail 4,0K Okt 23 17:05 mail The group mail has id 8 and the group crypt has id 9 The Problem is that dovecot will not go into the directory with group crypt! I always get the following error message: Dec 15 18:03:25 pop3(karsten@server): Error: user karsten@server: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/mountpoint/mail/server/karsten) failed: Permission denied (euid=107(Debian-exim) egid=8(mail) missing +x perm: /mnt, we're not in group 9(crypt), dir owned by 0:9 mode=0770) Dec 15 18:03:25 pop3(karsten@server): Error: Invalid user settings. Refer to server log for more information. But dovecot is definitely in the group crypt! What i am doing wrong? Regards Karsten

Maildir: do message files need to have a unique name across all directories?
by Gerben Wierda 15 Dec '16

15 Dec '16

While testing a new mail server I created a temporary account and filled its mailbox (Milder, dovecot) with the contents of another account. That means the actual message files in each account have identical names. Is that a problem? (I’m asking because I see some weird behaviour of visible/invisible messages and I wonder if this could have been the reason). G

postlogin script
by Michael Fox 14 Dec '16

14 Dec '16

I'm using the postlogin service, following the examples in the wiki. But I can't find any documentation on the behavior (what's allowed/not allowed) of the script-login binary. So, some questions: Question 1: The examples show the following at the end of the post-login.sh script: exec "$@" My understanding is that this would exec each of the command line arguments to the post-login.sh script. But, there are no arguments sent to the post-login.sh script in the examples. So what is this line supposed to do? Question 2: One of the examples shows exporting some environmental variables, followed by the above exec line: export MAIL=maildir:/tmp/test export USERDB_KEYS="$USERDB_KEYS mail" exec "$@" Now, I'm really confused. Can someone explain step-by-step why this does anything at all? Question 3: I'd like to be able to pass some information to the post-login.sh script, such as the service (%s), as a positional parameter. For example: executable = script-login /path/post-login.sh %Ls Or even more explicitly: executable = script-login /path/post-login.sh imap But it appears that the script-login binary is expecting only script names to be passed to it so that it can handle more than one script. Is there a way to pass arguments to the different scripts? Thanks, Michael

Is there a way to force dovecot to reprocess a user account to refile the m.* files based on new config for max file size. Ive got one account at 22k files due to a 2M split.
