[Dovecot] Sieve during read or login?
by Rick Romero 29 Sep '10

29 Sep '10

I was wondering if anyone thought of applying filters to email post delivery, pre-read. Basically the idea would be to head off Spam, Malware or Phishing for already delivered email. Malware would probably be the least likely target, as (knock on wood) user workstations would be updated, but a targeted phishing scam would not create a public signature that would be downloaded, yet an admin may have a regex that could be used to remove that email before it left the server. I used to run find and grep on my Maildirs, but that's no longer practical. I think maybe an 'on connect', or 'on read' might be an option. Thoughts? Rick

[Dovecot] Doubts with email copying
by Alex Baule 28 Sep '10

28 Sep '10

Hi Timo..... Trying to resolve my problem with the references in copying a email between Folders (when i move from inbox -> sent for example), i got some doubt. My plugin create a new ostream in v->save_begin, and i start a function from my library to create the reference, but when the email is been copying, the new email don't pass in this function, and i don't start my function to create a reference. My doubt is, if copying a email is a "copy + paste", why the s->save_begin it's not called ? I search in the iostream-internal.h to rewrite some "open stream" but the only one available is the close. There is a place to call my function every time that one ostream is opened, including the copy ?

[Dovecot] v2.0.4 released
by Timo Sirainen 28 Sep '10

28 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.4.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.4.tar.gz.sig multi-dbox users: Be careful about the INDEX change. Maildir users: I hope v2.0 is now finally stable. * multi-dbox: If :INDEX=path is specified, keep storage/dovecot.map.index* files also in the index path rather than in the main storage directory. WARNING: if you specified :INDEX= with earlier mdbox installation, you must now manually move the storage indexes to the expected directory! Otherwise Dovecot won't see them and will rebuild the indexes, possibly unexpunging some mails. - Maildir: Copying messages with hard links sometimes caused the source maildir's entire tmp/ directory to be renamed to destination maildir as if it were a message. - Maildir: v2.0.3 broke expunging copied messages sometimes - Maildir: INBOX whose tmp/ directory was lost couldn't be opened - single-dbox: Messages weren't copied with hard links - vpopmail support is hopefully working again. - dsync: POP3 UIDLs weren't copied with Maildir - dict file: Fixed fd leak (showed up easily with LMTP + quota)

[Dovecot] dsync is seriously broken when syncing maildir and mdbox
by interfaSys sàrl 28 Sep '10

28 Sep '10

Hello, I thought mdbox was production ready, but it seems to me that (in 2.0.4) it's quite broken. 1) The documentation only running this to convert from maildir to mdbox: *dsync mirror maildir:~/Maildir* but based on my experience and on posts on the mailing list, it's not enough. A namespace has to be defined and it's not clear whether / or . should be used as a separator. I tried with a dot first and the INBOX folders were empty. It seemed to work better with / 2) After having defined a namespace, running dsync again makes it spit tons of errors Error: Can't rename mailbox INBOX_28c716242e53784cc9030100d3b51c5c to INBOX: Target mailbox already exists Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and INBOX_4536121fce3ca14cf8c40c Info: INBOX/spam: only in dest Info: INBOX: only in source Each run will create more folders with GUIDs attached to the folder name. 3) Deleting these folders after having moved their content to the properly named ones seems impossible. I see a long list of folders in the bin and when I hit "Empty bin" in Thunderbird, nothing happens. There must must be a caching issue, because if I click on the folder, I'm told these folders don't exist. If I dsync again, I still have conflicts, with folders that are in the bin and then with new copies of INBOX Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and Trash/INBOX_4536121fce3ca14c Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX_4536121fce3ca14cf8c40000d3b51c5c At that stage, the newly created INBOXes cannot be deleted because they already exist in the bin. I renamed those folders, moved them to the bin, emptied the bin And it's still not fixed when running dsync Error: Mailboxes don't have unique GUIDs: 1a6f000a9751784c12030100d3b51c5c is shared by Sent and Trash/5 Info: Trash_INBOX_bb088f159336a14cc6bf0000d3b51c5c: only in dest Error: Can't rename mailbox INBOX to Trash_3: Renaming INBOX isn't supported. Why can't folder properly be deleted? I never had that problem with Maildir. Cheers, Olivier

[Dovecot] Command to get proxy connection count
by Brad Davidson 28 Sep '10

28 Sep '10

Timo, I'm trying to get a count of active proxy sessions on a given Director. I can of course enable verbose_proctitle and parse the 'N connections' string out of ps output or /proc/pid/cmdline. Is there a better way to do that, perhaps with doveadm? Goes back to needing a command for proxy and director ring status, I guess. -Brad

[Dovecot] Can't delete certain messages
by Karl Davenport 28 Sep '10

28 Sep '10

Running Dovecot version 1.0.10 on Ubuntu Server 8.04 amd64 (ext3). Some users have emails that will not go away. They delete them and the message is moved to the trash folder only to reappear when the mailbox is refreshed. Moving the message manually to another folder has the same effect. We are running Thunderbird as our email client, though I have tried using other clients to remove the messages. Here is my config: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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_privileged_group: mail mail_location: maildir:/home/%u/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 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): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd #End dovecot.conf Thanks in advance. -- Karl Davenport WaveCom Communications karl(a)wavecom-it.com 435-656-0972

Hello, I've tried to set the above in Dovecot 2.0.3, but according to ktrace (FreeBSD) it still fsync()s a lot (pop3 processes for example). Is this switch useful at all?

[Dovecot] Statistics
by Pierre 28 Sep '10

28 Sep '10

HI list, According to this: http://webcache.googleusercontent.com/search?q=cache:QMGLz9SVNdwJ:www.dovec… << # Use statistics to automatically distribute heavy users to different servers * v1.2 can export very detailed statistics via plugin >> I can't find this "detailed statistics" plugin, I only found this: http://www.dovecot.org/patches/2.0/stats-plugin.c But it only seems to add a "stats" IMAP command. Please can somebody confirm or give me a link to this plugin ? I really need to identify "heavy" users,so this plugin may be really usefull for me. Thanks a lot, Pierre

[Dovecot] Fixed mailbox id?
by Dieter Knopf 28 Sep '10

28 Sep '10

Hello, I have many Sieve rules and searching for a way to "track" renamings/moving of mailboxes (folders) on my IMAP server. Is there a unique ID for every folder available? I don't think there, i found no ID inside my folders :( If not, it think i need to create a ID-file for every folder and after that i can track the folders and update the rules =) Thanks

[Dovecot] Meaning of mail_max_userip_connections?
by Harald Strack 27 Sep '10

27 Sep '10

Hi, I set mail_max_userip_connections in our IMAP configuration to mail_max_userip_connections = 10 to allow users 10 parallel connections. It seems that this also limits the amount of parallel connections from one IP but different users?! Our users mostly accessing the IMAP server by a webmailer or proxies. Thus, all users (>10000) come from only 5 different IP. However, I got a lot of complaints about denied connections after setting mail_max_userip_connections = 10. Am I right with the meaning of this parameter? Thanks in advance Harry

[Dovecot] password_query, user_query and unrelated userid and emails
by Axel Luttgens 26 Sep '10

26 Sep '10

Let's say one has a SQL table with following fields for John Doe: login: u0007 password: {SHA1}... mailhome: /path/to/joeshome email: john.doe(a)example.com To log in, for internal policy reasons, John MUST make use of his userid "u0007". So, in the password_query, one would need something like: ... WHERE login = '%u' ... On the other hand, for receiving mail thru say, LMTP, one would need something like this in the user_query: ... WHERE email = '%Lu' ... With such a simplistic setup, this works fine: $ doveadm auth u0007 Password: passdb: u0007 auth succeeded but this one obviously fails: $ doveadm user u0007 userdb lookup: user u0007 doesn't exist and one has to do: $ doveadm user john.doe(a)example.com userdb: john.doe(a)example.com home : /path/to/joeshome I can't manage to devise a way to systematically refer to users thru their login, nor to avoid such messages: prefetch(u0007): passdb didn't return userd entries, trying the next userdb There sure must be a way thru adequate "SELECT ... AS ..." clauses. Could someone show me the light? Many, many TIA, Axel

[Dovecot] Settings for unlimited quota for some mailboxes
by Patrick Westenberg 26 Sep '10

26 Sep '10

Hello, I´m using Dovecot 2.0.1 with quota support (quota and imap_quota) which works perfect. However, I´d like to give some mailboxes unlimited quota. What quota setting (in the backend (SLQ)) is needed to tell Dovecot as LDA that the mailbox has unlimited quota? 0 or NULL or -1 or something else? Regards Patrick

[Dovecot] mdbox
by Daniel L. Miller 25 Sep '10

25 Sep '10

Reviewing some mailing list archives and the wiki, I still don't have a real clear picture of why I'd want to use mdbox. What I've taken from the info I've reviewed says mdbox is more complicated (than sdbox), has greater potential for breakage (simply because it's more complex), and has a theoretical performance impact depending on the exact filesystem/hardware used. Was that an accurate summary? Is mdbox something that was desired to solve a particular problem? -- Daniel

I'm running that doveadm command as root, with the -u <user> parameter, where <user> is a virtual user. Anyway, I've just read the wiki2 again, and noted that I don't really need the expire plugin, because it is only needed for the -A option. If I specify the -u parameter, it doesn't utilize the plugin. So I'm now using only the doveadm expunge -u ... command, which now gives me this output: # /usr/local/bin/doveadm -D expunge -u <user> mailbox sa.* SAVEDBEFORE 1d doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object ^^^ I'm curious about this error message.

[Dovecot] LDA + Postfix + LDAP + Sieve (Vacation): Wrong Domain in Reply
by Kendall Gifford 24 Sep '10

24 Sep '10

Hello everyone. I'm running dovecot (1.2.9) with postfix (2.7.0) on an ubuntu 10.04.1. I'm hosting mail for several domains and using the dovecot local delivery agent. Everything has been working great. However, today I set up a sieve script to send out-of-office replies (vacation) for one of our users. I tested it and got the response just fine. However, when looking at the "From" header of the auto-reply, I noticed that the domain name was wrong. My postfix master.cf line for doing local delivery is: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} My LDA configuration is: protocol lda { postmaster_address = postmaster(a)our-primary-domain.com hostname = our-primary-domain.com mail_plugins = sieve quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } So, our main "administrative" domain is: my-primary-domain.com, the mail server being mail.my-primary-domain.com. I sent an email to a user: janedoe(a)my-other-domain.com and the LDA with Sieve successfully sent me a reply. However, the "From" was: janedoe@mail instead of janedoe@my-other-domain. According to: http://wiki.dovecot.org/LDA/Sieve#Vacation_auto-reply > Vacation uses envelope sender and envelope recipient ... taken from: > ... > V 1.1+ > ... > Envelope recipient: -a parameter to deliver if given, otherwise -d parameter to deliver. If neither is given (delivering to system users), the $USER environment is used. Just for kicks I tried changing my master.cf to use -a instead of -d but then all mail delivers to user "mail" completely breaking all mail delivery. Anyhow, vacation auto-responders are fundamental to operations here and we manage mail for several separate companies. We need the "From" address to reflect the domain of the actual company. I'm stumped as to why sieve isn't getting/using the envelope sender's domain. I'm hoping someone here can point out (a hopefully obvious) mistake. I've attached my four pertinent config files as etc.tgz only slightly scrubbed. Any help is greatly appreciated. -- Kendall Gifford zettabyte(a)gmail.com
