[Dovecot] shared namespace problem
by Patrick Kaiser 08 Jan '10

08 Jan '10

Hi List, I've got a problem, setting up shared namespaces. I am trying to setup a Mailbox (Maildir) which is accessible for some users. (For example mailbox "sales" and only sales representive have access to it) Mailboxes can be found under /var/vmail/<username>, whereas <username> looks like foo.bar or peter.griffin ;) Now, if I connect via telnet, loggin in as foo.bar and run a03 SETACL foobar peter.griffin lwrxk everything seems fine. Under /var/vmail/foo.bar is a acl-file dovecot-acl-list Under /var/vmail/foo.bar/.foobar is a acl-file dovecot-acl The contents looks ok. Also there is a generated file /var/vmail/shared-mailboxes.db. But if i now loggin in as peter.griffin and setup command a03 LIST "" "*" or a03 LIST "" "#shared" I can not find any shared mailbox. Above you can find my actual configuration. I've tried several versions of location: under shared namespace, but without success. Hope someone has a clue and point me into the right direction. Thanks for your help.

[Dovecot] Dovecot Sieve: Vacation Recipient
by Lukas Kolbe 08 Jan '10

08 Jan '10

Hi! I tried to use the sieve vacation plugin, but we're facing a little problem: our user's addresses are <uid>@<domain>, and if they want to use imap and sieve, they can have a forward to <uid>@imap.<domain>. The return-path, and hence the address the vacation message is sent to, is then <uid>@<domain> and not the original sender of the message. Is there any way to circumvent this? Sending a vacation back to oneself doesn't really make sense here :) Oh, and happy new year and thank you all for this great piece of software! -- Lukas

Well, there might be scenarios, when a local user other than root may sniff the connection on localhost, but I think you have no such one. So to encrypt a connection from localhost to localhost is a waste of ressources. In case of Dovecot you'll need one extra file descriptior (and depending on your settings one extra process as well), plus the CPU time to actually do the encryption. > Yeah.

The webmail-frontend _is_ your client in the view of Dovecot. But since the cert is in /etc/ssl/certs, it should work, but if you validate the cert, the webmail may bark, because you access the SSL-cert with the CN "webmail.domain.gr" by another name "localhost". This is a sign of a man-in-the-middle attack, actually. BTW: Do your SSL IMAP/POP clients also use the name "webmail.domain.gr"? Otherwise they will get a warning as well, maybe each time they connect.

[Dovecot] First time Dovecot user, really impressed so far. What is best IMAP enabled webmail package to go with Dovecot?
by Stan Hoeppner 08 Jan '10

08 Jan '10

Greetings everyone, I'm new to the list as of today. I just installed Dovecot a couple of days ago for the first time, Debian Lenny Dovecot v1.0.15-2.3. So far I'm pretty impressed. I'm using mbox format with Dovecot auto-deciding to place mail in user home directories, which is great. It works very well with the Win32 Thunderbird 3 client over a small basic 100FDX switched net. I've got one list mail folder with 10,600 messages and server side body searching that folder via T-Bird is very quick, on the order of 5 seconds. It would probably be quicker if Dovecot threaded the search to use both CPUs, but pegging just the one CPU the search is still very darn quick. And this is on a dual P2-550 class machine with only 384MB RAM and a single 500GB 7200RPM SATA drive. I'd like to install a webmail package on the same host. I used Squirrelmail for this purpose many years ago and I wasn't wholly impressed with the user interface. I'm also not impressed by the fact that I regularly receive spam from compromised Squirrelmail hosts/accounts. I really like the look/feel of the Scalix Web Access AJAX based interface, but I can't/won't use Scalix as it's not supported on Debian, it has more features than I need, and the system requirements are a bit steep. So, what's the best FOSS IMAP enabled web mail front end with a modern look/feel? I'd like to run it on lighttpd, which I'm already using, not apache. Thanks in advance for any advice. My apologies if my first post is a little OT, but I figured there's probably no better place to ask about the best webmail front end for Dovecot than here. -- Stan

[Dovecot] Does Dovecot Sieve plug-in support Dovecot 2.0?

Does Dovecot Sieve plug-in support Dovecot 2.0? We have a few servers running Dovecot 2.0 beta1, but the Dovecot Sieve plug-in (version 0.1.4) won't compile against it. Is this on the Sieve TODO list? If so, when do you see it will happen? Thanks Wenjie

[Dovecot] Dovecot not delivering mail.
by Anthony Nedland 08 Jan '10

08 Jan '10

I get no errors when attempting to send or receive. However, my messages aren't showing up in the mailboxes. I am sending between users on the same server. This is my dovecot -n output ------------------------------------------------ # 1.1.11: /etc/dovecot/dovecot.conf Error: Error in configuration file /etc/dovecot/dovecot.conf line 1076: Unknown section type (section changed in /etc/dovecot/dovecot.conf at line 1038) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf ----------------------------------------------- I was under the impression that this would be an irrelevant message, as my actual dovecot configuration file is dovecot-postfix.conf rather than dovecot.conf. The logging shows login/logout and no errors. Thanks.

Unfortunately the Thunderbird developers are not convinced. Maybe somebody on this list can comment on this? Many thanx Harri

[Dovecot] auth, partially resolved
by Spyros Tsiolis 07 Jan '10

07 Jan '10

Hello people, After a lot of wading through the dovecot documentation (which btw, is excellent !, everything lies under "dovecot/doc/wiki"), I managed to authenticate a couple of accounts. For starters, I want dovecot to work as an imap/imaps box and nothing else. So , I went ahead and created a "passwd" file with two users. One user being my name (spyros) and plaintext password and the other user "postmaster" with encrypted password ("/etc/dovecot/passwd" shown) : --- spyros@webmail.domain.gr:{PLAIN}plainpassword postmaster@webmail.domain.gr:{SSHA}SSHAPassword --- Now, if I telnet to port 143 with both users, the system comes back with the following : --- [root@webmail dovecot]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- As I said, it allows login on port 143 for both users. So, the same for "postmaster". Now for port 993 : --- [root@webmail dovecot]# openssl s_client -connect webmail.domain.gr:993 [lots of SSL-related certificate information] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- Again, the same for user "postmaster". I don't paste. So, everything is fine. However, I have an issue with the (?!) issued certificate. If I check the dovecot logs I find nothing. If on the other hand, I do the same check on the Horde application, It comes back with the following : --- * Trying protocol imap/notls, Port 143: SUCCESS - INBOX has 0 messages (0 new 0 recent) * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAIN[SERVERBUG] Internal error occurred. Refer to server log for more information.

However, I would like an opinion before I go ahead and bug them with this. Certificate was created with "dovecot/doc/mkcert.sh" and the relevant certificate file (can't recall its name at the moment). Any help would be appreciated. On the other hand, If I went too far with this I apologize and I'll try to find another way to resolve this. Thank you people, s.

The above filenames are timestamp_hostname.pid, and that seems pretty unique right? Regards, Cor

The end result would be something like what follows: Dovecot implementation (proposed): ------------------------------------- <dovecot.conf> dict { dict_sieve = ldap:/etc/dovecot/dovecot-sieve-ldap.conf } plugin { # TODO: proxy this dict? sieve_extsrc = dict } </dovecot.conf> then I'm not sure how you specify multiple hosts with the dict-sql format, so I'm using the postfix convention. there's probably a better way for dovecot. <dovecot-sieve-ldap.conf> map { name = responder_mode server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_mode result_scope = sub bind = no version = 3 } map { name = responder_text server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_text result_scope = sub bind = no version = 3 } map { name = forward_keep server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardKeep result_scope = sub bind = no version = 3 } map { # in this case we can have many responses name = forward_addresses server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardAddress result_scope = sub bind = no version = 3 } </dovecot-sieve-ldap.conf> Sieve language: --------------------- then with proposed new functions of the sieve language (all names plucked out of my head 2hrs ago, would have to think about the semantics some more): 1. a “:list” argument that expects a string-list 2. a “:extsrc” argument that expects an <ext-name: string> and returns a string-list 3. a “:extsrc1” argument that expects an <ext-name: string> and returns a string 4. a new test that uses information that is not in the message, say “arbitrary [comparator] string string” (syntax needs work) sample uses in scripts are then: 1. redirect to a mailing list sourced from ldap (or wheverver): # mailForwardAddress attribute can be present >=0 times redirect :list :extsrc “dict:forward_addresses” 2. decide whether to keep or discard forwarded messages (eg: after the above rule) # mailForwardKeep attribute should only be present once, if at all if arbitrary :is :extsrc1 “dict:forward_keep” “TRUE” { keep; } 3. decide vacation action and text based in information in an ldap dir: # mailResponderMode & mailResponderText attrs should only be present once, if at all if arbitrary :is :extsrc1 “dict:responder_mode” “alwaysreply” { vacation :days 1 :extsrc1 “dict:responder_text"; } if arbitrary :is :extsrc1 “dict:responder_mode” “holiday” { vacation :days 30 :extsrc1 “dict:responder_text”; } ... where the "dict:mapname" syntax would be dovecot implementation specific. could also support the URL & TAG-URI schemes as proposed by draft-ietf-sieve-external-lists. This would allow query URLs as a more general case, using whatever's configured in /etc/ldap/ldap.conf (or whatever the platform's ldap client lib uses). Doing this does raise some resource consumption concerns, hence there should probably be a means of restricting external queries to global scripts only (or sieve_before, sieve_after), and a means of providing timeout values, etc. eg: if arbitrary :is :extsrc1 “ldap:///o=myorg?mailForwardKeep” “TRUE” { keep; } I'll keep on thinking about the design, staring intently at the dovecot sources and http://wiki.dovecot.org/Design for another couple days before attempting to write some code to test this. Feedback on the design of both the sieve language extension, & dovecot interface very appreciated. Cheers, -Martin Foster

[Dovecot] Failed IMAP Login Attempts in Logs
by Carlos Williams 06 Jan '10

06 Jan '10

I had a user telling me that they can't login to the Postfix email server via Webmail (RoundCube) and I decided to see if I could locate this issue in the logs and understand if the user was simply using a wrong password credential and or something more serious. More than likely the person is just using a wrong password but in search of this on my logs, I don't understand why Dovecot doesn't log failed login attempts. When I attempted to login with a wrong password, I show the following in my logs: [root@mail log]# cat /var/log/maillog | grep 'Jan 5' | grep -i 'dovecot' | grep -i 'carlos' Jan 5 11:00:13 mail dovecot: imap-login: Disconnected: user=<carlos>, method=PLAIN, rip=::ffff:192.168.0.10, lip=::ffff:192.168.0.10 Is there a log level or something I am not searching for that will allow me to see failed or invalid logins for Dovecot (IMAP)? Thanks!

[Dovecot] Sorting in IMAP list command?
by Ronald Johnson 06 Jan '10

06 Jan '10

Hi All, I'm running Dovecot 1.2.9 and have noticed the IMAP list command does not appear to send a sorted list of folders with list command. For example on our Cyrus server I get a sorted list of folders (with INBOX listed first): 2 list "" "*" * LIST (\Noinferiors) "/" "INBOX" * LIST (\HasNoChildren) "/" "CalProject" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "Drafts" ... while on our Dovecot server I get seemingly random listing: 2 list "" "*" * LIST (\HasNoChildren) "/" "lsf" * LIST (\HasNoChildren) "/" "mrg" * LIST (\HasNoChildren) "/" "studiosysadmins" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "TriTeam" * LIST (\HasNoChildren) "/" "systemupdates" * LIST (\HasNoChildren) "/" "bb" * LIST (\HasNoChildren) "/" "nagios" * LIST (\HasNoChildren) "/" "server" ... Is this intentional, or have I done something wrong? I didn't see any option in the dovecot.conf to set the behavior of the list output.

[Dovecot] Dovecot quota not working
by Bruno Guimarães Sousa 05 Jan '10

05 Jan '10

Hi everyone, I'm trying to make quota to work in dovecot 1.0.rc15 in a Debian machine. Setting the limit to 1GB and starting to fill up the mailbox and nothing stopped me. It just kept growing and nothing happened. Restarted the service and nothing. I had already exceeded the 1 GB limit and nothing happens, the mailbox still goes bigger and bigger... The *"check_quota"* plugin for squirrelmail shows "0.0% of 1.0GB" in my browser. 1GB is exactly what it is defined in dovecot.conf by maildir. Is it necessary to configure something in postfix?

[Dovecot] imap default separator ignored?
by Harald Dunkel 03 Jan '10

03 Jan '10

Hi folks, I have configured the imap folder separator to '/' (see below). AFAIU the separator character does not affect the internal folder representation managed by Dovecot, but just the communication between client and imap server. Question is: What is supposed to happen if I try to create a folder named "a.b" in this configuration? Since '.' is not a separator character anymore, and since the client doesn't know anything about the internals of Dovecot, I do not see why Dovecot complains about an invalid character? Shouldn't it hide its internal Maildir structure?

[Dovecot] What auth ?
by Spyros Tsiolis 03 Jan '10

03 Jan '10

Hello people, First of all a Happy New Year and best wishes to you all. I've managed to setup dovecot v1.2.9 on a CentOS 5.4 system and I am now, trying to make it auth. I would prefer virtual users and only want to make the IMAP/ IMAPS part work. I don't need POP3 or anything else. The rest will be handled by another SMTP/POP3 application. Now, I almost managed to make dovecot auth a virtual user with his password. However, when it seems it has passed the auth stage (either via IMAP _or_ IMAPS), the command line kicks me out. Here's roughly what I did : 1. Created /etc/dovecot/users and /etc/dovecot/passwd 2. filled in a couple of usernames/passwords encrypted in MD5 format 3. Ran dovecot from command line (service dovecot start [after I created the service ofcourse]) 4. telneted to localhost via port 143 or 993 (with the help of openssl: "openssl s_client -connect the.system.name:993") 5. typed : . login username@fqdn <password> Something worth noticing for step "5". If I do this logging-in with the "user@fqdn" format, the systems kicks me out. I, then, check the latest on "/var/log/dovecot/errors" to find that the system does not complain about the auth. If I do the same logging-in but instead use "user@localhost" (and not the fqdn), the system fails the authentication stage and does _not_ drop me into the shell. Go figure !! Anyway. My question, in essence, is this; Which type of auth should I use ? The manuals (that i've been sinking my head for the last couple of weeks) suggest I should use PAM. PAM, I cannot understand. At the moment, I _think_ I am using MD5. Any pointers here ? I've been reading the /doc/wiki directory for quite some time until it made no sense to me anymore (too much info makes me loose perspective). Any help would be greatly appreciated. TIA, spyros

[Dovecot] disable lazy_expunge for some mailboxes?
by Frank Cusack 03 Jan '10

03 Jan '10

How to disable lazy_expunge for certain mailboxes? My problem is I have a public namespace, whose mail is on a different filesystem than user mails. Some users are allowed to expunge on this shared mailbox, but lazy_expunge is stopping that from working since the mail has to cross a filesystem boundary to make it into the lazy_expunge namespace (location is under the user's home directory). As a workaround can I run a daily cron job to remove messages with the \Deleted flag on them? If so how do I find them? thanks -frank

by Michael 02 Jan '10

02 Jan '10

I would a method for Dovecot to recalculate the quota usage and rewrite it to the quota DB (Called on demand by a non-Dovecot POP3 daemon) I don't want the line deleted in the DB as this would only recalculate next time the Dovecot LDA or IMAP handles a message, and I want to keep the data availability contiguous. Can this be done?

[Dovecot] nested folders
by Jim Pazarena 02 Jan '10

02 Jan '10

using both thunderbird and roundcube with dovecot IMAP, I can create all the folders I desire, but cannot create subfolders; I also cannot delete a folder once created. I get a very un-informative error message from each. Is there a special setting required to permit sub-folder creation? folder deletion? I've got 770 mail:mail virtual_user_home 770 mail:mail mail_sub-directory 770 mail:mail .imap 660 mail:mail .subscriptions 700 mail:mail Drafts 700 mail:mail INBOX 700 mail:mail Junk 700 mail:mail Sent 700 mail:mail Trash Suggestions would be appreciated. Thanks!

[Dovecot] Using Push IMAP to trigger POP3 download
by Aaron Whitehouse 02 Jan '10

02 Jan '10

Hello all, I have an HTPC connected 24/7 to the Internet running Mythbuntu. I also have a web/email host that runs Dovecot for email and provides IMAP and POP3 access. I understand that Dovecot supports Push IMAP and I could, for example, use Thunderbird to connect to my email host to receive instant email as it arrives. I would like to add a Dovecot IMAP server on my HTPC (for increased storage, to aggregate multiple email accounts, to process messages with SpamAssassin and to provide a better webmail interface) and retrieve email from my webhost to my HTPC by POP3. To set up POP3 on my HTPC, I understand that the norm is to set a time interval (say, every 10 minutes) for clearing email. What I would prefer to do, if possible, would be to have Dovecot on my HTPC keep a Push IMAP connection with Dovecot on my webhost. When a new message is available on the webhost, my HTPC would be "pushed" a notification and it could do a POP3 download. This would allow it to clear emails with POP3 (and reduce storage requirements on my webhost), mean that I received emails instantly and not require me to have it poll for messages on a very-regular basis. Does anybody know if this is possible? As an alternative (not solving my space problem on the webhost, but solving the others), is it possible to set up Dovecot to "piggy back" off an existing IMAP server? In my example, my webhost does not offer good spam-checking and webmail. Would it be possible for me to set up a Dovecot server on my HTPC that received messages by Push IMAP, processed them with SpamAssassin (say, moving all of the spam messages to a subfolder) and provided a good web interface, all the while providing updates to the webhost's server? In some ways, this is almost more like an IMAP client than a server. I apologise if these questions are stupid! Happy New Year and thanks in advance, Aaron -- FSF Associate Member: 5632 http://www.fsf.org

[Dovecot] Deliver virtual user's mail to a specific namespace?
by Brian Schang 02 Jan '10

02 Jan '10

Hello: I have virtual users set up for the various mailing lists that I subscribe to. Everything has been working well in both Postfix and Dovecot. Postfix is configured to deliver to a specific mbox file within my mbox mail root. I can access retrieve and read email via Dovecot without any issues. Now I want to make my setup more robust and have these messages delivered to a maildir namespace. I have configured the LDA within the Postfix master.cf file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} I have configured the 'dovecot' transport within Postfix in the transport file: test(a)lists.schang.net dovecot: In dovecot.conf I have set up the namespace as follows: namespace private { separator = / prefix = "Lists/" location = maildir:~/MailLists subscriptions = yes } I'm having a hard time specifying the "Lists/" namespace in my userdb passwd-file: test:{PLAIN}linux:2000:200::/home/brian::userdb_mail=maildir:Lists/test I can't get the userdb_mail portion to work. For this user, 'test(a)lists.schang.net', how do I tell Dovecot/deliver to put the message in the 'test' mailbox within the 'Lists/' namespace? I'd appreciate any insight. Thank you. -- Brian Schang

[Dovecot] Issue Authenticating to a new dovecot-postfix installation
by Anthony Nedland 02 Jan '10

02 Jan '10

(Apologies if this is a resend, but I thought I had received a bounceback message.) I have installed dovecot-postfix and postfixadmin on an Ubuntu 9.10 machine. The userdb and passdb are both mysql. If I set up a user in postfixadmin they are able to send. I can successfully telnet into the server remotely by name on 110 and 25. I'm not looking for any authentication encryption/ssl any of that, just POP3/SMTP. When I telnet into 110 I can enter a username with user [username] then when I do pass [password] I get -ERR Authentication failed. I know the user info is correct. When I set up an account in Outlook Express I get "There was a problem logging onto your mail server. Your Password was rejected:" Also saying -ERR Authentication failed.'. (0x800ccc90,0x800ccc92) So basically the same thing. I can attach the tutorial I used in as a .doc if that would help.

[Dovecot] Dovecot LDA with SetUID
by Michael 02 Jan '10

02 Jan '10

Has anyone been able to get Dovecot LDA working where each user has a different UID? All the howtos on the Internet I have found set the UID of a mailbox as fixed for all users. However I have tried to run it on the current SQL database we have (with different UID per user) and I get the following: Jan 1 16:25:40 HOST dovecot: deliver(EMAIL): Fatal: setgid(1000(stdusers)) failed with euid=8(mail), gid=12(mail), egid=12(mail): Operation not permitted I am calling this from Postfix with: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

[Dovecot] Quota with Dict + SQL not updating
by Michael 01 Jan '10

01 Jan '10

Hello all, I have a Dovecot server deployed with a MySQL back end. If the user logs in and there is no quota set for them in table 'quota', the system will automatically inset a line with their username and current messages/storage. However after this it fails to update the information when to reflect new messages coming to their inbox after the original insert of the information. It will only update the information when a user deletes a message. Why is it not updating this information every time their mail is checked with IMAP? Cheers, Michael

[Dovecot] Oracle SQL driver
by Alexander Bukharov 31 Dec '09

31 Dec '09

Hi all. Recently I was looking for an IMAP-server with Oracle support and unfortunatelly I couldn't find one. It was a surprise for me but there is no such functionality at all. So I've chosen an IMAP-server with most flexible and convinient architecture that was Dovecot-1.2.9 and written a driver for Oracle RDBMS support. I used Oracle Pro*C so a Pro*C preprocessor is needed to compile the driver. There is a lot of logging there that should be removed. It would be great if you consider to include this driver to mainstream so Dovecot will be the first IMAP server supporting Oracle as auth backend. All related files are attached. Cheers.

[Dovecot] A Dovecot Sieve spam filter question.
by aja-lists＠tni.org 31 Dec '09

31 Dec '09

Hi, I'd like to make a filtering threshold for users to let them deal with spamassassin spam-level starred < 8 themselves, but spam-level starred higher than 8 should be discarded how can one do that with the "anyof" option ? the following doesn't work with a test email with "gtube", which scores > 999 : # require "fileinto"; if header :matches "X-Spam-Level" "\*\*\*\*\*\*" { fileinto "discard"; } and I think it would be nice to have not so many lines in the globalsieverc file. TIA, Regards, Adrian

[Dovecot] Pigeonhole Sieve IMAP flag question
by Julian Cowley 31 Dec '09

31 Dec '09

Hello, Here is a small script that I've been running to test a problem I've been seeing. Shouldn't this result in the mail being delivered to the inbox as a new message (ie. without the \Seen flag)? require "imap4flags"; addflag "\\Seen"; removeflag "\\Seen"; Every message gets delivered to the inbox as though it's already been read. Using Dovecot 1.2.9 and Pigeonhole Sieve 0.1.14.

[Dovecot] Hostname setting defaults
by Timo Sirainen 30 Dec '09

30 Dec '09

Any thoughts about the following? hostname setting currently defaults to system's host name, without the domain part. It's used (in v2.0): - dovecot-lda (new deliver): If -a parameter isn't specified and there's no Envelope-To: header, the destination address is generated as <username>@<hostname setting> - lda/lmtp: In generated Message-Id: headers ("dovecot-stuff@<hostname>") for rejects, vacation, etc. - lda/lmtp: in reject messages as part of MIME boundary, and also in "Reporting-UA: <hostname>; Dovecot mail delivery agent" header. - lmtp: In the protocol, e.g. "220 <hostname> Dovecot ready" or "421 4.4.2 <hostname> Disconnected for inactivity" - lmtp: In added Received: header Seems pretty clear to me that it should be host.domain.org, not just host. So I suppose I'll change that default. The other thing is postmaster_address. That's accidentally been postmaster(a)example.com in dovecot-example.conf and uncommented. So who knows how many installations have their postmaster address set to that.. I'm thinking of just commenting it out in next v1.2 release so admins needs to change that. But for v2.0 maybe there could be a good default for postmaster_address? "postmaster@<hostname setting>" I think? Because it's postmaster(a)host.domain.org instead of postmaster(a)domain.org, it might not be correct in most installations, but I'm thinking that maybe it's safer. Someone trying out Dovecot on testbox.biguni.edu probably doesn't want bounces going to postmaster(a)biguni.edu..

[Dovecot] dovecot-shared
by Frank Cusack 30 Dec '09

30 Dec '09

I'm confused about dovecot-shared. If the file exists, \SEEN flags are NOT shared? So if dovecot-shared exists, flags are actually private. The doc seems clear on this (albeit not worded very well). I only question it because intuitively you would think the opposite. If backwards compatibility is the reason for this reverse behavior, the file should have been named dovecot-private-flags. In fact that's a great name to stick a list of flags (one-per-line) that are private. -frnak

Re: [Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 30 Dec '09

30 Dec '09

Thanks for the reply. I won't be changing any files, or even accessing them, i'll simply be passing the filename along to "another system". I'm not allowed to change this other system or any of its interfaces. The other system has been in place and is "off limits" as far as changes go (I'm told). To make it simple, this other system needs to be notified of any flag changes on emails. So, when we detect a flag change (in our plugin), we need to pass the message filename along to this other system. I hope this makes sense...and again...i'm not justifying the need for it, but I have to play the hand i'm dealt....Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040-----Original Message-----From: "Timo Sirainen" [tss(a)iki.fi]Date: 12/29/2009 04:02 PMTo: "Tony Rutherford" CC: dovecot(a)dovecot.orgSubject: Re: [Dovecot] Retrieve Physical Message FilenameOn Tue, 2009-12-29 at 15:50 -0500, Tony Rutherford wrote: > Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm > overriding "update_flags":void my_mail_update_flags(struct mail > *_mail, enum modify_type modify_type, enum mail_flags flags)For this > email which is having its flags updated, I need to retrieve the > physical filename of the message.

I've looked around, and I'm guessing > it exists, but I don't see it offhand. The problem is that by the time you're trying to access the file, its flags may have already changed, which also means its filename could have changed. So even if you got it, your code would probably randomly fail. What exactly are you going to do with the filename? Maybe you should instead be opening the file with mail_get_stream() and doing something with the fd. This message is intended solely for the individual(s) to whom it is addressed. If you are not the intended recipient, any dissemination or copying is strictly prohibited. If you believe you received this message in error, please notify the sender and delete from your system.

Hello, What does this information mean and how is it relevant? I cannot find documentation other than a brief description in dovecot.conf: %t - number of TOP commands %p - number of bytes sent to client as a result of TOP command %r - number of RETR commands %b - number of bytes sent to client as a result of RETR command Thanks in advance, Cliff

[Dovecot] Mail storage creation fails with virtual users
by Scott H. W. Snyder 30 Dec '09

30 Dec '09

So I have recently set up dovecot with a virtual users dovecot.passdb file, but when I attempt to telnet in, it fails because my virtual users don't have proper permissions to create mailboxes. I don't want to have to create actual users for each email account. Any idea as to what to do? The error that dovecot logs: dovecot: Dec 28 13:06:28 Error: IMAP(user1): mkdir_parents(/var/mail/ folders/user1) failed: Permission denied dovecot: Dec 28 13:06:28 Error: IMAP(user1): Mail storage creation failed with mail_location: mbox:/var/mail/folders/user1/:INBOX=/var/ mail/user1 dovecot: Dec 28 13:06:28 Error: child 27667 (imap) returned error 89 my [test] passdb file: user1:{PLAIN}pass1:2001:2001:User 1 Name:/var/mail/folders/user1:: mail_plugins=cmusieve user2:{PLAIN}pass2:2002:2002:User 2 Name:/var/mail/folders/user2:: mail_plugins=cmusieve user3:{PLAIN}pass3:2003:2003:User 3 Name:/var/mail/folders/user3:: mail_plugins=cmusieve user4:{PLAIN}pass4:2004:2004:User 4 Name:/var/mail/folders/user4:: mail_plugins=cmusieve Conf settings: -bash-3.2# /usr/local/sbin/dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /usr/local/var/run/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.info.log protocols: imap listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run//login login_executable: /usr/local/libexec/dovecot/imap-login login_greeting: Hi buddy, have an account ? max_mail_processes: 2048 verbose_proctitle: yes first_valid_uid: 1000 last_valid_uid: 5000 mail_location: mbox:/var/mail/folders/%u/:INBOX=/var/mail/%u mail_debug: yes mbox_read_locks: dotlock fcntl auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /usr/local/etc/dovecot.passdb userdb: driver: passwd-file args: /usr/local/etc/dovecot.passdb socket: type: listen master: path: /usr/local/var/run/dovecot-auth-master mode: 432 user: dovecot group: mail
