I would like 'some process' to store old mails at a cheap storage. I know how to do it with symlinks, but I don´t know if it is the best option. So, I´m asking if dovecot improves it somehow.

[Dovecot] Mail archive

Hi, I´m using dovecot at our storages, accounts is distributed among many storages (not entire domain), all of them with compression (when message > 30Kb), nightly crontab script. Even though compression and many storages, we always have problems with disk space and need to migrate accounts. Have you ever implemented any archive solution working with dovecot ? Regards, Fernando

[Dovecot] Mail not begin proccessed
by Andre Labuschagne 10 Aug '09

10 Aug '09

Good day all, [Dovecot version 1.2.1] I've set up postfix and dovecot on Centos. I have a problem with the mail, it is begin received but not "processed" by dovecot. I've looked in the maillog file and found two problems; the first is that private/dovecot directory (I think it should be a directory) did not exist and the second problem is "mail transport unavailable". I've create a directory called /var/spool/postfix/private/dovecot but I get the following error in the log file: Connection refused (Is this an ownership issue? I've made the owner postfix) As for the second problem, I've spend the most of the past 3 days googling the error and found very little "useful" information. Do I need to supply more info? Best regards, Andre

[Dovecot] Released Sieve v0.1.11 and ManageSieve v0.11.8 for Dovecot v1.2.3
by Stephan Bosch 10 Aug '09

10 Aug '09

Hello Dovecot users, Apart from unfinished development of the date extension, this is a set of bug-fix releases. A few portability issues were found, a few stupidities were fixed and the ManageSieve proxy now also works with TLS. Most notably, the include extension had an issue regarding the expansion of $HOME in the personal include path. I've built a project site at: http://pigeonhole.dovecot.org Changelog Sieve v0.1.11: + Built skeleton implementation for the date extension (RFC5260). It compiles, but it does not do anything useful yet. Therefore, it is not part of the default compilation. - Fixed ARM portability issues caused by char type not being signed on that platform. Reading optional operands from a binary would fail for action side effects. Also, an accidental mixup of an int return type with bool caused the interpreter to continue on ARM even though an error occured. - Removed direct stdint.h includes to prevent portability issues. - Fixed segfault bug in the handling of script open failures. - Include: improved user error messages and system log messages. - Fixed copy-paste mixup between sieve_after and sieve_before settings in the LDA Sieve plugin. If only a sieve_after script was active, nothing would have been executed. Patch by Mike Abbott. - Include: fixed a bug in HOME substitution in the sieve_dir path. Surfaced in ManageSieve. Changelog ManageSieve v0.11.8: - Fixed TLS support for proxying ManageSieve. The protocol state machine was incorrect. Also added a check that disables ssl when 'starttls' is not enabled for the user. This produces a proper warning in the log file. There is no such thing as a managesieveS protocol which has SSL from the start. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.11.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.11.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.8.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.8.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.3-managesieve-0.11.8.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.3-managesieve-0.11.8.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] virtual plugin and ACL
by Nikita Koshikov 10 Aug '09

10 Aug '09

Hello list, We are using virtual plugin for to provide users two additional folders: Company/all - it contains all messages in user's mailbox Company/favorites - here is flagged messages. Here is namespace part of config file: namespace private { prefix = Company/ separator = / location = virtual:/var/mail/virtual:INDEX=MEMORY:LAYOUT=maildir++ subscriptions = no } Everything works fine, but problem arises when someone rename or delete virtual mailbox. With above config, 1 user make changes to his mailbox, but changes distribute for entire domain. First, I have tried to add :CONTROL=/data/mail/%d/%n/data/virtual to location part of virtual namespace, but I have no luck with such settings. Directory /data/mail/%d/%n/data/virtual not even been created. Then I tried to setup ACL for virtual mailbox. Adding "acl" to mail_plugins in imap and lda section and acl=vfile to plugins config. Under /var/mail/virtual in each mailbox I create dovecot-acl file contaning: user=koshikov.n lrwstiekxa authenticated lrwstipe But this didn't work. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN] Server ready. a login test qwe a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH QUOTA] Logged in a list "" * * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "Company" * LIST (\HasNoChildren) "/" "Company/all" * LIST (\HasNoChildren) "/" "Company/favorites" a OK List completed. a select Company/all * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1249459221] UIDs valid * OK [UIDNEXT 14] Predicted next UID * OK [NOMODSEQ] No permanent modsequences a OK [READ-WRITE] Select completed. a getacl a BAD Error in IMAP command GETACL: Unknown command. a rename Company/all Company/test a OK Rename completed. After "rename completed" in /var/mail/virtual new file dovecot-acl-list is appear with content: 1249457074 test How can I get workaround for this situation ? I just need to restrict my users renaming and deleting virtualboxes.

[Dovecot] how secure is Dovecot when exposed to the Internet?
by Florin Andrei 10 Aug '09

10 Aug '09

$ dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-11-server x86_64 Ubuntu 9.04 protocols: imap imaps managesieve I need to make an IMAP (actually imaps) server available over the Internet. Unfortunately, VPN is not available (not all clients support VPN), so I will have to expose the imaps port to the Internet. My question is: how reliable is Dovecot in such a setup? I am not talking about encryption (protecting the traffic between server and client). I am talking about having the daemon exposed to anything coming in from the Internet, buffer overflows and stuff like that. What's the security history of this software in situations like this? -- Florin Andrei http://florin.myip.org/

[Dovecot] Wiki entry for expire plugin, PostgreSQL trigger needs update
by Stefan Förster 09 Aug '09

09 Aug '09

The wiki entry at http://wiki.dovecot.org/Plugins/Expire needs an update for Dovecot 1.2 and PostgreSQL: -- v1.2+: CREATE OR REPLACE FUNCTION merge_expires() RETURNS TRIGGER AS $$ BEGIN IF exists(SELECT 1 FROM expires WHERE username = NEW.username AND mailbox = NEW.mailbox) THEN UPDATE expires SET expire_stamp = NEW.expire_stamp WHERE username = NEW.username AND mailbox = NEW.mailbox; RETURN NULL; ELSE RETURN NEW; END IF; END; $$ LANGUAGE plpgsql; CREATE TRIGGER mergeexpires BEFORE INSERT ON expires FOR EACH ROW EXECUTE PROCEDURE merge_expires(); At least that's what I think after looking at the code: iter = dict_iterate_init(dict, DICT_EXPIRE_PREFIX, DICT_ITERATE_FLAG_RECURSE | DICT_ITERATE_FLAG_SORT_BY_VALUE); /* We'll get the oldest values (timestamps) first */ while (dict_iterate(iter, &key, &value) > 0) { /* key = DICT_EXPIRE_PREFIX<user>/<mailbox> */ userp = key + strlen(DICT_EXPIRE_PREFIX); [...] T_BEGIN { username = t_strdup_until(userp, p); If this code does somehow iterate usernames which are not present in the dict, I apologize.

[Dovecot] User Auth
by Richard Harwood 09 Aug '09

Hello all, I am new to the mailing list and I'm in the process of setting up a LAMP + mail server. I have configured my MTA (Postfix) to deliver messages to: /var/spool/mail/vhosts/domain.tld/name I have configured Dovecot as follows: -- # 1.2.2: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:/var/spool/mail/vhosts/%d:INBOX=/var/spool/mail/vhosts/%d/%n mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)example.com auth default: debug: yes passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd -- Password excepted, my passwd.dovecot file containing a single virtual user looks like: richard:{plain}password:504:505::/home/vmail The uid/gid is the same as used by Postfix (a dedicated vmail user/group). That user/group owns the mbox I am trying to manipulate in this example. When I attempt to login via telnet on port 110 I get the error: +OK Dovecot ready. user richard(a)richardaharwood.com +OK pass password -ERR Authentication failed. It seems to dislike the fact I specify the domain as part of the login username. If I repeat and login as: user richard - I am authenticated, however I get the error: -ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information. Tailing the maillog, I see the following: Aug 8 17:19:01 richardaharwood dovecot: auth(default): client in: AUTH 1 PLAIN service=pop3 secured lip=83.170.110.193 rip=83.170.110.193 lport=110 rport=58115 resp=<hidden> Aug 8 17:19:01 richardaharwood dovecot: auth(default): passwd-file(richard,83.170.110.193): lookup: user=richard file=/etc/passwd.dovecot Aug 8 17:19:01 richardaharwood dovecot: auth(default): client out: OK 1 user=richard Aug 8 17:19:01 richardaharwood dovecot: auth(default): master in: REQUEST 4 3603 1 Aug 8 17:19:01 richardaharwood dovecot: auth(default): passwd(richard,83.170.110.193): lookup Aug 8 17:19:01 richardaharwood dovecot: auth(default): master out: USER 4 richard system_groups_user=richard uid=500 gid=500 home=/home/richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): Effective uid=500, gid=500, home=/home/richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): mbox: data=/var/spool/mail/vhosts/:INBOX=/var/spool/mail/vhosts//richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): fs: root=/var/spool/mail/vhosts, index=, control=, inbox=/var/spool/mail/vhosts//richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): open(/var/spool/mail/vhosts//richard) failed: Permission denied (euid=500(richard) egid=500(richard) missing +x perm: /var/spool/mail/vhosts/) Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): Couldn't open INBOX: Internal error occurred.

I also notice the effective uid/gid is not that specified in the passwd file? The uid/gid appears to be that of my own ssh account which is not connected to the mail account that I wish to simply access as a virtual user. Would anyone be kind enough to point me in the right direction? In a nutshell, where am I going wrong with my authentication? This is a basic setup for the time being, until I get my head around it, but any pointers would be really appreciated. Have spent quite a few hours but I don't feel much closer to getting to the bottom of it! :) Many thanks, Richard
