[Dovecot] replacement for IMAP_EMPTYTRASH=Trash:7
by Rody 08 Feb '08

08 Feb '08

While running dovecot on debian etch using version 1.0.rc15-2etch3, i wonder the following: If i read the config files correctly, dovecot seems to have no equivalent of courier's IMAP_EMPTYTRASH=Trash:7 setting. Therefore, i wrote a script that dives into the user's directories and their maildirs. It looks like this: ============================================= #!/bin/bash for pad1 in $(ls /home) do if [ -e "/home/$pad1/Maildir/.Prullenbak" ] then find "/home/$pad1/Maildir/.Prullenbak/cur" -mtime +2 -type f -delete find "/home/$pad1/Maildir/.Prullenbak/new" -mtime +2 -type f -delete fi if [ -e "/home/$pad1/Maildir/.Allerlei.Spam" ] then find "/home/$pad1/Maildir/.Allerlei.Spam/cur" -mtime +2 -type f -delete find "/home/$pad1/Maildir/.Allerlei.Spam/new" -mtime +2 -type f -delete fi done ============================================ Now, can i just put a script like this in /etc/hourly or do i have to add things like stopping the dovecot deamon (i sure hope not!) in order to prevent file-corruption? Or has dovecot in the meantime got a config option that does this just like courier does? Rody

[Dovecot] location of .subscriptions
by Jochen 08 Feb '08

08 Feb '08

Hello, I just installed dovecot (1.0.10) to replace UW-IMAP. So far almost everything works. But I need shared folders (mbox format). I hope I've set up everything but when a user subscribes to one of the shared folders a file .subscriptions with perm 600 is created in the parent directory of the shared mailboxes ("namespace public" below). As I understand the docs that file should go to the user's home directory, right? What did I wrong? Thank you in advance. Here is my dovecot.conf (comments and blank lines stripped): ---- snip ---- protocols = imap imaps pop3 disable_plaintext_auth = no ssl_disable = yes mail_location = mbox:~/mbox:INBOX=/var/mail/%u:INDEX=/var/mailindexes/%u namespace private { inbox = yes } namespace public { prefix = Public/ location = mbox:/var/spool/imap:INDEX=/var/mailindexes hidden = no } mail_full_filesystem_access = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol lda { } auth default { mechanisms = plain passdb shadow { } userdb passwd { } user = root } dict { } plugin { } ---- snip ---- --

[Dovecot] Thunderbird can't see a maildir named .Inbox (yeah I know, poor name)
by Adam McDougall 08 Feb '08

08 Feb '08

I discovered by chance while migrating some user email to dovecot, one of them had a mailbox called "Inbox" and my script migrated it to a Maildir called .Inbox but Thunderbird could not see it at all, even in subscription lists. I tested with my account and it looks like mutt CAN see it. This seems like a client issue so I'll just make my migration script rename anything called Inbox to avoid it, but I thought I would send a note incase anyone else trips on it.

[Dovecot] Can't get apop to work.

Hi Folks, I'm fairly new to linux so this message may reflect that. dovecot info (running on CentOS 5.0): protocols: pop3s listen: ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.pem login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_uidl_format: %v.%u auth default: debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd If I select apop as one of the allowed protocols (in order to avoid having to use ssl) I get this error message in the mail log : "APOP mechanism can't be supported with given passdbs" I tried fiddling with PAM by adding an /etc/pam.d/apop file with these contents : auth required pam_unix.so nullok account required pam_unix.so makes no difference, in anycase as much reading as I;ve done to understand PAM I still have not much clue: the docs are quite obscure. My /etc/pam.d/dovecot file looks like this : #%PAM-1.0 auth required pam_nologin.so auth include system-auth account include system-auth session include system-auth At this point I seem to be out of options.

[Dovecot] Editing sieve scripts via webmail?
by Tobias Balle-Petersen 07 Feb '08

07 Feb '08

Hello... I have dovecot 1.0.10 running with the sieve plugin and virtual users (LDAP). My webmail is squirrelmail. I want to allow the users to create sieve-scripts via a squirrelmail-plugin. The plugins seems to require that the IMAP-server is cyrus. What are the options for dovecot? Thanks, Tobias

[Dovecot] Static list of users with passdb pam
by Koen Vermeer 07 Feb '08

07 Feb '08

Hi, On my system, I want to provide imap access for some of the users listed in /etc/passwd. The list of users should be provided by me, and should just be a list in a text file. All the userdb options are static (uid, gid, home directory). Unfortunately, I cannot think of a way to configure Dovecot to do this. The closest I get is with: passdb pam {} userdb passwd-file { args = /path/to/passwd-file } However, the passwd-file is now more complex than it really needs to be, as it includes fields for password, uid, gid and home directory as well. Is there some way to handle this? Or am I trying to do something stupid? Thanks! Koen

[Dovecot] Doubt on adding support for new mailbox format
by Armando Adami Zaro 07 Feb '08

07 Feb '08

Hi! I'm starting to read and play with dovecot since a month ago. But my mailboxes' format is hashdir, which has been implemented here by my team. Here: http://wiki.dovecot.org/MailboxFormat I've noticed that "Adding support for new formats for Dovecot isn't very difficult, although it can be time consuming. Dovecot exposes a nice and simple API which needs to be implemented" But I couldn't find that API. I've read the documentation so many times but have not found. Can you help me? Thanks a lot! -- Armando Adami Zaro Canopus Informática Ltda Porto Alegre - RS - Brasil +55 51 3062-2404

[Dovecot] Convert plugin question
by Dmitry Filonov 06 Feb '08

06 Feb '08

Hi, Is it possible to change convert plugin, so it would keep old UIDVALIDITY and UIDNEXT after conversion from mbox to Maildir? As far as I can tell, this shouldn't be a big problem as this information already exists in the mbox. Well, at least for mboxes, that have that information. The problem is easy, if UIDVALIDITY changes during conversion, then client has to reload whole mailbox from the server. And this is not easy for users with 5+ Gb of mail. Thanks, FiL

[Dovecot] Sieve
by Fred Newtz 06 Feb '08

06 Feb '08

Alright, so I know I need to get sieve installed. Seems fairly easy to make happen. However, in the documentation it tells me to find dovecot-config and supply that directory into the --with-dovecot= configuration option. For some reason I do not have that file on my machine. I have used find / -name 'dovecot-config' to search for it and it is not there. Is it going to be a problem that the file is not on my machine? Thanks, Fred

[Dovecot] LDA postfix + deliver, problem lookup, accepting email for everyone
by Sylvain Viart 06 Feb '08

06 Feb '08

Hi, I'm setting up dovecot pop3 deamon for a small set of mailbox. I want to be able to set a small set of mailbox simply, so I've used "passdb passwd-file" + virtual mailboxes with "userdb static". My problem is that it seems that postfix accept and create mailbox for every address I post. It is configured to use local delivery through dovecot's deliver. How do I force deliver to retrun an error if the destination is not defined in the passwd-file? The doc said that "userdb static" should do a lookup automatically. But no luke for me. Is it really a deliver problem, or a postfix configuration problem? Any, hint?

Hi Charles Charles Marcus a écrit : >> dovecot --version >> 1.0.rc15 > > Please upgrade first - this is very old. Yep, you're right, but it's debian etch package version. Is it known to be broken, using this version? I've fought with other software compilation, if I can avoid to do it one more time... Thanks noticing that. Regards, Sylvain.

[Dovecot] High availability strategies?
by Ed W 06 Feb '08

06 Feb '08

Anyone here trying any "high availability" strategies for mail servers? (Ralph what do you do?) I am reading up a little on DRBD + OCFS for a master/master setup but this doesn't seem to address how to avoid having a single master proxy process (assuming that we are running on rented equip and don't have ability to shift IP addresses around servers). It appears to be possible to play games with DNS and short expiries, but this causes extra DNS traffic for the general case when we are up and running? We had some bad ram in a server recently and it's the worst possible situation. Server locking up, downtime, but it's not easy to repro and fix... (only happens every few days. Memcheck found nothing...) How could we redesign our setup to be resilient against this? (How does Google or Yahoo do it?) For reference I am using vservers to host dovecot and this is working very nicely and makes it real simple to chuck the config onto another host and test things (upgrades, etc). Highly recommended. Any suggestions (from people who have tried stuff)? Cheers Ed W

[Dovecot] IMAP quotas - Reasonable size?
by Tobias Balle-Petersen 05 Feb '08

05 Feb '08

Hello... I'm setting up dovecot (IMAP only) at an ad-agency (Lots of big files attached to mails). I'm wondering... What would you consider to be reasonable mail quota? My concern is, that some client-software will have problems with huge mailboxes. I was going to give everyone 2GB, but some users demand 15GB+. Does dovecot "prefer" mailboxes within a certain size? Looking forward to hear your thoughts on the subject. Thanks, Tobias Balle-Petersen

If I run the user_query of: user_query = SELECT 1000 AS uid, 1000 AS gid, maildir AS home FROM mailbox WHERE username = '%u' AND active = '1' Everything works fine but if I run the user_query of: user_query = SELECT 1000 AS uid, 1000 AS gid, maildir AS home, concat('quota=maildir:storage=', floor( mailbox.quota / 1024 )) AS quota FROM mailbox WHERE username = '$u' AND active = '1' if I were to run the query from MySQL the I get: +------+------+----------------------------------+------------------------------+ | uid | gid | home | quota | +------+------+----------------------------------+------------------------------+ | 1000 | 1000 | mattrude.com/lists@mattrude.com/ | quota=maildir:storage=512000 | +------+------+----------------------------------+------------------------------+ If I run the above query I am unable to log into the server: Feb 4 20:06:11 dovecot: imap-login: Internal login failure: user=<lists(a)mattrude.com mythtv(a)mattrude.com From=akstcaloprestimnsdgs(a)alopresti.com File=/tmp/clamav/virus.7Q >, method=PLAIN, rip=192.168.1.10, lip=192.168.1.1, TLS ## Dovecot configuration file #protocols = imap imaps pop3 pop3s protocols = imap imaps login_user = postfix listen = ssl_listen = ssl_disable = no ssl_cert_file = /etc/pki/dovecot/certs/dovecot.pem ssl_key_file = /etc/pki/dovecot/private/dovecot.pem auth_cache_size = 128 auth_cache_ttl = 600 mail_location = maildir:/var/spool/virtualmailboxes/%d/%u/imap/:INBOX=/var/spool/virtualmailboxes/%d/%u/:INDEX=/var/spool/virtualmailboxes/%d/%u/imap/index/ protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)mattrude.com hostname = samantha.mattrude.com mail_plugins = cmusieve mail_plugins = quota sieve_global_path = /var/spool/sieve/dovecot.sieve mail_plugin_dir = /usr/lib/dovecot/lda auth_socket_path = /var/run/dovecot/auth-master } auth default { mechanisms = plain digest-md5 cram-md5 userdb sql { args = /etc/dovecot-mysql.conf } passdb sql { args = /etc/dovecot-mysql.conf } user = root count = 2 } dict { } plugin sql { quota = maildir:storage=1048576 quota = maildir:ignore=Trash } If anyone sees what im missing please let me know Thanks -Matt

[Dovecot] NULL for password and proxy fields
by bill-dovecot＠carpenter.ORG 04 Feb '08

04 Feb '08

In the course of experimenting with getting dovecot proxying to work, I took a guess at two things. These work fine for me, but now I'm wondering if they are "as designed" or just a lucky accident that might stop working in the future. (I'm using dovecot 1.0.rc17, which is the included version in Ubuntu Feisty. (I am aware that some details change in v1.1, and I'm not worried about that right now.) http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy 1. The wiki page says about password forwarding, "Make sure that the authentication succeeds with any given password. You can do this by using empty passwords." I didn't know exactly now to interpret that last part, so I tried returning NULL as the value of the "password" field for proxy cases. That seems to make dovecot skip the password check will forwarding the user-submitted password to the proxy target host. Is that the intent of that part of that wiki page? 2. It looks like any value at all for the "proxy" field in the passdb lookup turns proxying on. The one exception is a value of NULL for "proxy", in which case proxying is not turned on and proxy-related other fields are ignored. Is that how it's intended to work? If someone can give and informend confirmation that this is as-designed, I can add some clarifying remarks on those points on the wiki page. Thanks. -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] appending domain based on port
by Eric Hester 04 Feb '08

04 Feb '08

I am looking for a way to append a domain to unqualified user names based on the port that the client connected to. Like this: port 9110 - @test.com port 9111 - @other.com port 9112 - @third.com it looks like auth-default-realm does this, but you can only specify it once for the whole process. I know I could do this by running a separate copy of dovecot attached to each port in question, but I would like to do it all in one process if possible. Other questions I have, if I use the auth-default-realm: 1) does it happen before auth lookup I assume? 2) do I have to define the domain i use here as an auth-realm in addition to default?

[Dovecot] Postfix, mailbox_command, Dovecot deliver, LDAP and mail_location
by Patrick Ben Koetter 02 Feb '08

02 Feb '08

I am trying to tell Dovecot deliver to use $mail_location as the location to store mail for system users. From the docs I've read <http://wiki.dovecot.org/MailLocation> I believe this is possible, but mail to my system users always gets delivered to their /home/<USERNAME> homedirectory. Here's what I've done so far: # Postfix main.cf mailbox_command = /usr/lib/dovecot/deliver # Dovecot # dovecot-ldap.conf user_attrs = mailHomeDirectory=home,mailUidNumber=uid,mailGidNumber=gid,mailQuota=quota=maildir:storage,mail=mailHomeDirectory Above you can see, I query for $mail as documented in <http://wiki.dovecot.org/UserDatabase>. # dovecot.conf # dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/mail.state-of-mind.de.crt ssl_key_file: /etc/ssl/private/mail.state-of-mind.de.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: maildir:~ mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(imap): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 ntlm passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: virtual group: virtual What am I missing?
