[Dovecot] Create IMAP folders on first login?
by Andreas Ntaflos 23 Jan '08

23 Jan '08

Hello list, I am currently playing around with a virtual domain/virtual user setup and thanks to the documentation on both the Dovecot and the Postfix websites things are going swimmingly (apart from an oddity I will post separately about). On trying things out with different newly created virtual users I wondered if it was possible for Dovecot to create certain IMAP folders on the first login of the user? So that folders such "Drafts", "Sent" and "Trash" are created automatically for each new user (upon login). Or is this a job for the mail client, or for the admin who creates the new users? TIA!

[Dovecot] Problem with quota support on debian etch
by Sascha Bendix 22 Jan '08

22 Jan '08

Hi, sorry but I'm new to dovecot and this list and don't know how to proceed with my dovecot installation. I was trying to set up an Mailserver with Postfix, Dovecot and PostgreSQL. Everything was working fine till I wanted to integrate quota support. When I activate it by adding quota to the the imap plugin section (like described in the wiki) I get the following error every time I try to login: Jan 20 19:32:07 kauket dovecot: IMAP(user(a)dmain.de): Unknown quota backend: quota=maildir Jan 20 19:32:07 kauket dovecot: child 11288 (imap) returned error 89 Jan 20 19:32:07 kauket dovecot: imap-login: Login:user=<user(a)domain.de>, method=plain, rip=::ffff:1.2.3.4, lip=::ffff:1.2.3.5, TLS I tried to set quota = maildir:storage=10240 in the plugin section, too and got the same error. I already talked to some dovecot users bot nobody could help me and I hope you can give me an advice what could be the mistake. Here is my Config: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: [::] ssl_cert_file: /etc/ssl/certs/kauket.maedness.de.crt ssl_key_file: /etc/ssl/certs/kauket.maedness.de.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: dovecot-auth mail_extra_groups: mail mail_location: maildir:/var/mail/%h mail_plugins: quota imap_quota auth default: user: dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf # grep -ve '^[ ]*#' -e '^$' dovecot-sql.conf driver = pgsql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 10000 AS uid, 8 AS gid, quota=maildir:storage=' || quota AS quota, maildir AS home FROM mailbox WHERE username = '%u' The system is a debian stable (etch) with package version 1.0.rc15-2etch1 and dovecot --version tells 1.0.rc15. I know the this version of dovecot is a little bit ancient but I hope you can still help me. I even don't know if it's only a bug in the package or if it's a bug in dovecot itself. I thank you for all clues and advices. Sincerly yours, Sascha

[Dovecot] Virtual Users and permission denied on POP3 Authentication - cur directory
by John Dubchak 22 Jan '08

22 Jan '08

Hi, I've been working on configuring a new Postfix+Dovecot+Cyrus-SASL +Postgres server to perform multi-domain virtual hosting with non-unix accounts. I believe I have everything working correctly and have tested both the SASL portion and POP authentication through telnet and all works as expected, with one exception. When I authenticate using POP3: # telnet mail.host 110 Trying 192.168.XXX.XXX... Connected to mail.host. Escape character is '^]'. +OK Dovecot ready. user user1(a)domain1.com +OK pass secret +OK Logged in. -ERR No INBOX for user. And the maillog reports the following: Jan 21 13:42:32 mail.host dovecot: pop3-login: Login: user=<user1>, method=PLAIN, rip=192.168.XXX.XXX, lip=192.168.XXX.XXX Jan 21 13:42:32 mail.host dovecot: POP3(user1): mkdir(/var/spool/ virtual_mailbox/domain1.com/user1/cur) failed: Permission denied Jan 21 13:42:32 mail.host dovecot: POP3(user1): mkdir(/var/spool/ virtual_mailbox/domain1.com/user1/cur) failed: Permission denied Jan 21 13:42:32 mail.host dovecot: POP3(user1): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-01-21 13:42:32] Jan 21 13:42:32 mason dovecot: POP3(user1): No INBOX for user top=0/0, retr=0/0, del=0/0, size=0 The directory structures for the virtual mailboxes are: /var/spool/virtual_mailbox/domain1.com/user1 /var/spool/virtual_mailbox/domain2.com/user1 And the entire tree from virtual_mailbox down is owned by vuser:vuser. The directories have permissions 700. What I believe is happening is that Dovecot is trying to use the uid and gid of user1, who doesn't have a system account, rather than vuser's when writing to the virtual_mailbox folders. I'm not sure how I can configure Dovecot to use the vuser information. Here is my dovecot.conf: ------------------------------------------------------------------------- protocols = imap pop3 listen = [*] disable_plaintext_auth = no syslog_facility = mail mail_location = maildir:/var/spool/virtual_mailbox/%h # Default umask to use for mail files and directories. #umask = 0077 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_debug_passwords = yes auth_debug = yes auth_verbose = yes auth default { # SQL database passdb sql { args = /etc/dovecot-sql.conf } userdb sql { args = /etc/dovecot-sql.conf } user = root } ------------------------------------------------------------------------- Any insight will be appreciated, I've been working on this non-stop for several days now and can't seem to figure it out. Thanks, John

[Dovecot] Problem downloading mail with "large" attachment using Thunderbird....
by Bjørn T Johansen 22 Jan '08

22 Jan '08

We have a user that is using Thunderbird on Windows to read mail over IMAP and it works ok, except for downloading mail with "large" attachment.. When opening a mail with a attachment with a size of 14-15MB, TB downloads the attachment seemingly ok, but TB stops when reaching 99%. After TB has stopped, if the user tries to select another mail, TB just hangs and it has to be closed and started again to work again... I have checked the dovecot log, but I can't find anything there... We have also tried to create a log in TB but everything looks ok there also... Is there a known problem with TB and "large" attachment or does anyone know how to fix this, if possible?

[Dovecot] Maildrop script to sieve
by Raphael Bittencourt S. Costa 21 Jan '08

21 Jan '08

Hi, I'm working on a system that have about 350K e-mail users and 100k users that uses maildrop scripts to make filters on their delivery. So, changing scripts by hand can't be a choice. I "googled" so much and I wasn't able to find any script that converts maildrop scripts to sieve. Does anyone knows where can I find it? By the way, does anyone uses dovecot-1.1-beta on a production system with sieve+maildir+lda? Thanks, Raphael Costa

[Dovecot] Exim Dovecot Authentication Problem
by Marc Perkel 21 Jan '08

21 Jan '08

Having a hard time figuring out something that is supposed to be easy. Tryiong to configure Dovecot so that it provides authentication to Exim for outgoing smtp. Tried different things and getting authentication socket protocol error dovecot_plain: driver = dovecot public_name = PLAIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth1 auth default { # Space separated list of wanted authentication mechanisms: # plain digest-md5 cram-md5 apop anonymous mechanisms = plain # # Password database is used to verify user's password (and nothing more). # You can have multiple passdbs and userdbs. This is useful if you want to # allow both system users (/etc/passwd) and virtual users to login without # duplicating the system users into virtual database. # # http://wiki.dovecot.org/Authentication # # PAM authentication. Preferred nowadays by most systems. # Note that PAM can only be used to verify if user's password is correct, # so it can't be used as userdb. If you don't want to use a separate user # database (passwd usually), you can use static userdb. passdb passwd-file { # Master users that can log in as anyone args = /etc/dovecot.masterusers master = yes pass =yes } # Linuxconf passwd-like file with specified location passdb passwd-file { args = /etc/exim/control/vmail/shadow.%d } # Linuxconf passwd-like file with specified location userdb passwd-file { args = /etc/exim/control/vmail/passwd.%d } # User to use for the process. This user needs access to only user and # password databases, nothing else. Only shadow and pam authentication # requires roots, so use something else if possible. Note that passwd # authentication with BSDs internally accesses shadow files, which also # requires roots. Note that this user is NOT used to access mails. # That user is specified by userdb above. user = root # Number of authentication processes to create count = 10 } # It's possible to export the authentication interface to other programs, # for example SMTP server which supports talking to Dovecot. Client socket # handles the actual authentication - you give it a username and password # and it returns OK or failure. So it's pretty safe to allow anyone access to # it. Master socket is used to a) query if given client was successfully # authenticated, b) userdb lookups. # listener sockets will be created by Dovecot's master process using the # settings given inside the auth section auth default_with_listener { mechanisms = plain passdb passwd-file { # Master users that can log in as anyone args = /etc/dovecot.masterusers master = yes pass =yes } passdb passwd-file { # Path for passwd-file args = /etc/exim/control/vmail/shadow.%d } userdb passwd-file { # Path for passwd-file args = /etc/exim/control/vmail/passwd.%d } socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } } } auth external { mechanisms = plain passdb passwd-file { # Master users that can log in as anyone args = /etc/dovecot.masterusers master = yes pass =yes } passdb passwd-file { # Path for passwd-file args = /etc/exim/control/vmail/shadow.%d } userdb passwd-file { # Path for passwd-file args = /etc/exim/control/vmail/passwd.%d } socket listen { client { path = /var/run/dovecot/auth-client mode = 0666 } } }

[Dovecot] Squirrel Mail (unknown date) in subject and zero size of messages shown
by Niki Spassov 21 Jan '08

21 Jan '08

Hello, I'm having the following problems with a Squirrelmail and Dovecot. with option SERVER SIDE SORTING in Squirrel, only the first page with e-mails is shown in user's inbox, the mails in all the next pages are listed with subject: "(unknown date)" and size 0. The other similar problem, independent from that option (SERVER SIDE SORTING) is: when THREAD VIEW is chosen, we have the same behavior, normal first page and damaged all the others. with option SERVER SIDE SORTING = FASE, and UNTHREADED, everything is OK Has anyone seen this behavior, any help will be greatly appreciated. Thank you in advance :) P.S. Squirrel's version is 1.4.7 and Dovecot is 1.0-stable

Re: [Dovecot] Time just moved backwards error even with ntpd
by Alexander Moisseev 21 Jan '08

21 Jan '08

On some FreeBSD 6.2 systems I was solved this problem just by adding to crontab: @hourly /sbin/sysctl `/sbin/sysctl -e machdep.adjkerntz` >/dev/null 2>&1 For some explanation, see: http://lists.freebsd.org/pipermail/freebsd-hackers/2005-August/013383.html Quote follows: ... It seems that CMOS clock is updated using resettodr(9) function. There seem to be only a few occasions when this function is called: 1. clock_settime(ClOCK_REALTIME) // through kern_time.c:settime() 2. settimeofday() // through kern_time.c:settime() 3. machdep.adjkerntz sysctl is set I believe that ntpd calls *settime-family* functions *only* if time offset is *larger* than *128ms* (or maybe I am thinking about ntpdate), but normally it uses ntp_adjtime() to adjust time keeping. Obviosuly, a system running ntpd with good enough hardware clock and good enough connection to good enough ntp server(s) would use the latter method all of the time after some initial stabilization period. But it seems that time changes are *never propagated to CMOS* in this case, ... Alexander
