[Dovecot] Dovecot + NFS + FreeBSD breakage ?
by Xavier Beaudouin 04 Jun '14

04 Jun '14

Hi, I am trying to update my old mails servers from dovecot 2.1.15 to 2.2.12 (freebsd ports) and upgrade to FreeBSD 10.0-P3. My mail storage are on NFS with index also. On 2.1.15 everything is ok, and in 10-mail.conf I have the good things to be added as wiki tell me (eg http://wiki2.dovecot.org/NFS) BUT, when I try a single connection like : $ telnet ::1 110 Trying ::1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user test@domain +OK pass thebloodypass Connection closed by foreign host. Looking the log : Jun 4 10:09:10 mail03 dovecot: master: Dovecot v2.2.12 starting up for imap, pop3, lmtp Jun 4 10:09:20 mail03 dovecot: pop3-login: Login: user=<test@domain>, method=PLAIN, rip=::1, lip=::1, mpid=5540, secured, session=<7x47Jf76IQAAAAAAAAAAAAAAAAAAAAAB> Jun 4 10:09:20 mail03 dovecot: pop3(kiwi(a)oav.net): Fatal: nfs flush requires mail_fsync=always This is very strange since : # doveconf -n | grep -E 'sync|nfs' mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes So either there is some breakage somewhere or something that is buggy somewhere...

[Dovecot] Change in LAYOUT=fs between 1.2.9 and 2.0.19?
by Martijn 04 Jun '14

04 Jun '14

While testing an upgrade from Dovecot 1.2.9 (on Ubuntu 10.04 LTS) to 2.0.19 (12.04 LTS) I encountered the following change in behaviour: In both setups, mail_location is defined as follows: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs No other mail_location-related settings are set in the config. On 1.2.9 this leads to new mail being delivered to this example directory: /home/username/domains/example-domain.ext/webmaster/.Maildir/INBOX/new/ On 2.0.19 the exact same mail_location is set, but new mail is now delivered to: /home/username/domains/example-domain.ext/webmaster/.Maildir/new/ Notice the missing /INBOX/ in the path on 2.0.19. I found no mention of this change on http://wiki2.dovecot.org/Upgrading/2.0 which first lead me to suspect this was a bug in 2.0.19. However, while browsing the 2.0-wiki I found a page which sheds some light on the behaviour that is to be expected from Dovecot 2.0.x. Quote from http://wiki2.dovecot.org/MailLocation/Maildir#Directory_layout > "Mailbox directory name": "Without DIRNAME, INBOX will be stored at ~/Maildir/{new,cur,tmp}/, but when DIRNAME is specified, we get an extra path component INBOX/ immediately prior to the DIRNAME value, so in the example above INBOX would be stored at ~/Maildir/INBOX/mAildir/{new,cur,tmp}/." I then changed mail_location to have an empty DIRNAME, like: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs:DIRNAME= It appears this fixes the problem for new mail arriving (haven't tested other folders yet). Questions: 1. Is this a deliberate change in behaviour between the two versions? If so, may I suggest adding this change to the Upgrading to 2.0 wiki page, because I was unable to find the relevant info quickly. If not, is this a misconfiguration on my side, or a (known) bug in one of the two versions? 2. Is the DIRNAME=(empty) a good solution, or is it unusual/hacky to leave DIRNAME empty? Any particular problems I may expect using this configuration? Thanks in advance for your help. -- Kind regards, Martijn

[Dovecot] Info about sharing mail folder
by Gianluca Calloni 03 Jun '14

Hi to all. First of all.. I'm new on the mailing list.. So.. Sorry in advance for any mistake or error on posting here.. The question (or doubt..) is about sharing mail folder. I use a test mail server. Is not the production server (always dovecot + postfix + spamassassin + clamav) Well.. In test mail server i can use the share folder, follow the conf istruction on wiki dovecot. And work fine. But i need to know if is possible for user_a(a)mydomain.com to share only 1 or 2 subfolder (E.g. .INBOX.FOLDER_A and .INBOX.FOLDER_B shared, .INBOX_FOLDER_C not shared) When i do some test sharing folder, the user with wich user_a(a)mydomain.com share the mailbox can view all the subfolder of user_a(a)mydomain.com Following my dovecot versione e config. Thank's in advance My dovecot version is 2.0.19 My dovecot conf is : # 2.0.19: /etc/dovecot/dovecot.conf doveconf: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied calloni@dovecot:~$ sudo -i [sudo] password for calloni: root@dovecot:~# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-49-generic i686 Ubuntu 12.04.4 LTS ext4 dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = acl mail_uid = vmail namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = yes location = maildir:%%h:INDEX=~/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl } postmaster_address = postmaster(a)jodovit.local protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Thi

Not offhand, but if you want a remote tool, it ought to be simple to cobble together some feeder script and netcat (or openssl s_client). It will also be simpler if you configure the master password feature so you don't have access to all user passwords. So something like this for dumping the INBOX contents #!/bin/sh master-user=masteru master-password=masterp while read user server; do netcat --ssl $server 993 <<_EOF_ >${user}.report 1 LOGIN ${user}*${master-user} ${master-password) 2 SELECT INBOX 3 ... 4 LOGOUT _EOF_ done I don't know enough IMAP to fill in "3 ..." to dump all headers, but I'm sure it's not hard to find out. It's even simpler if you don't need to do it remotely: just use doveadm fetch -A hdr MAILBOX '*' Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] list all emails from command line?
by Tomasz Chmielewski 03 Jun '14

03 Jun '14

This is not strictly Dovecot question, but a more general IMAP one. I'm running a Dovecot server and have a user who is claiming that some email sent to him, say, on 30 May, showed up in his mailbox on 02 Jun. I've checked Postfix logs, and the message was correctly received on 30 May and passed to Dovecot. A similar issue happens every few days. This leaves me with two possibilities: 1) Dovecot is somehow not presenting the new mail to the user in a "timely manner" 2) user's email program is broken Therefore, I wanted to do some kind of "IMAP list" of the account, with a command line tool: - specify username, pass and server, - the tool would return a list of all email in their folders (message ID, From, To, Date, Subject). I would run it i.e. daily and this would let me verify when the mail was really visible in the account. Is anyone aware of a tool I could use to achieve that? -- Tomasz Chmielewski http://www.sslrack.com

[Dovecot] dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database
by Christian Hoffmann 02 Jun '14

Hello everyone, I have a small problem with dovecot installed on ubuntu-13.10. I use dovcot as LDA with a LDAP-passdb and a pam-passdb. The userdb is static. A mail to LDAP-user 'foo' is delivered with the error-message dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database A mail to the pam-user 'bar' will deliverd without this error. But both users should work with the static-userdb. Where is my mistake?
