by Steven King 21 Feb '09

I am testing out the new Dovecot 1.2.beta1 software. I am getting reports from people using POP3 that it randomly drops connections.

[Dovecot] Maildir with INBOX and other folders at same level
by Seth Rhudy 21 Feb '09

21 Feb '09

Hello- I have set up Dovecot before and feel fairly comfortable with it but am having some issues with a new setup and have not been able to find a solution via Google or the list archives. I use offlineiimap to sync an IMAP account with an email provider. After the sync is complete, my ~/Maildir is set up with a folder called INBOX (with cur,new,tmp inside) and all my other folders set up at same level as INBOX (also with cur,new,tmp inside): ~/Maildir INBOX cur new tmp Otherfolder1 cur new tmp Otherfolder2 cur new tmp etc.. This email provider says that they use '/' as the IMAP folder separator so '.' can be used in folder names. Anyway, I am using Dovecot 1.0.15 on Debian Lenny and can't seem to get Dovecot to recognize this folder structure and display it in my MUA. In my dovecot.conf, I have: mail_location = maildir:~/Maildir When I fire up my MUA it connects fine but does not display anything -- the INBOX is empty and the other folders are not there. I have tried various configurations with the namespace private {} section but without success. What am I missing? Thank you in advance for your assistance.

[Dovecot] Sendmail + Deliver as an LDA probs
by ben 21 Feb '09

21 Feb '09

Hi, I'm having trouble setting up sendmail to be able to use dovecot deliver as an LDA... I don't want to be able to deliver mail locally, everything should go via deliver (virtual user setup)... And i'm confused about all the procmail/lda entry's in different sendmail config files... When using $# deliver -u testuser < testmail <-- he delivers my mail in the correct mailbox as stated in my dovecot passdb file homedir. So deliver is working fine ! ---- I used the dovecot.m4 from wiki.dovecot.org/LDA/sendmail sendmail.mc fragment (only lines affecting Local delivery) : DOMAIN(`blaat')dnl MODIFY_MAILER_FLAGS(`LOL', `-S')dnl FEATURE(`local_procmail')dnl define(`LOL_MAILER_PATH',`/usr/bin/procmail')dnl define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail')dnl dnl MAILER(`local')dnl MAILER(`smtp')dnl MAILER(`procmail')dnl MAILER(`dovecot')dnl dnl ------ blaat.m4 fragment : define(`LOCAL_MAILER_PATH',`/usr/bin/procmail') define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail') ------ more /usr/local/src/sendmail-x.x/cf/mailer/dovecot.m4 : ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/opt/dovecot/libexec/dovecot/deliver, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=deliver -d $u ------- virtusertable/virtusertable.db : test(a)testdomain.com blaatuser --------- aliases/aliases.db : blaatuser | /opt/dovecot/libexec/dovecot/deliver -d $u ---- sendmail.cw = empty ----- mailertable/mailertable.db : testdomain.com dovecot:dovecot ################# When I run #$ sendmail -bv test(a)testdomain.com sendmail gives : test(a)testdomain.com... deliverable: mailer local, user test (as a matter of fact the user test does exist on my machine, so what he does is stripping of the domainname and he delivers the mail in /var/spool/mqueue/test :-/ ) And I don't see anything in my deliver logfile of course...

[Dovecot] location of temporary files in deliver
by Stuart Henderson 21 Feb '09

21 Feb '09

deliver has the following: -- -- -- /* After buffer grows larger than this, create a temporary file to /tmp where to read the mail. */ #define MAIL_MAX_MEMORY_BUFFER (1024*128) ... static struct istream *create_raw_stream(int fd, time_t *mtime_r) ... input = i_stream_create_seekable(input_list, MAIL_MAX_MEMORY_BUFFER, "/tmp/dovecot.deliver."); -- -- -- On most of my systems, /tmp is relatively small (a few hundred MB, and sometimes on ramdisk), and I like to use /var/tmp for larger temp space. I just had a problem where I exceeded the space available in /tmp while delivering a (multi recipient) message and had to modify the above line to use an alternative location, and recompile. Would it be appropriate to make this a configurable option instead? Thanks.

[Dovecot] How many namespaces for several groups of shared mailboxes ?
by Thomas Hummel 21 Feb '09

21 Feb '09

Hello Timo, let's say you want to implement several distinct groups of shared mailboxes via one (several) public namespace(s) with dovecot-1.1.x/Maildir. For instance, team1, team2 and team3 work on different projects (project1, project2, project3). Obviously, as many public namespaces (#team1, #team2, #team3) would do the trick, but then, any user (including users who don't belong to any above team) would 'see' useless non-selectionable folders #team*. So my idea would be to create only one public namespace (#Public) into which I'd store directories team1, team2, team3, into which I'd put the needed shared mailboxes. Something like /courriel/boites/public/team1/.shared-project1/ /team2/.shared-project2/ /team3/.shared-project3/ with something like namespace public { separator = / prefix = '#Public/' location = maildir:/courriel/boites/public inbox = no hidden = no list = yes subscriptions = yes } I guess if unix right and ACL are set up correctly, other people would only see non-selectionable '#Public'. The only problem is the subscription file : my understanding is that you have only one subscription file per namespace. Maybe unless you specify something like location = maildir:/courriel/boites/public:CONTROL=<some user dependent location> But wouldn't that induce another problem : such a CONTROL directive would put dovecot-uidlist and dovecot-keywords in the same user dependent location. As I want to share the \Seen flag, I have to . put a dovecot-shared file . not specify INDEX (or at least, not to some user dependent location) So I would end up with . uid lists in some user dependant location (as a side effect of having several subscriptions files) . but indexes shared as uid is listed in index : wouldn't that be a problem ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Quota not reporting with getquotaroot

20 Feb '09

I'm running squirrelmail on top of dovecot, and noticed that some of my users display the quota (using the squirrelmail plugin check_quota) and some don't. So I did some digging. For those that do not display the quota, their account also doesn't provide any data with: . getquotaroot inbox * QUOTAROOT "inbox" . OK Getquotaroot completed. When I check the account /Maildir folder it has info in maildirsize 0S 12744423 10 334 1 483685 1 and when I delete the maildirsize file it recreates. any ideas? thx.

[Dovecot] Different protocols with different auth-types
by Morton.Trust 20 Feb '09

20 Feb '09

Hello, I have installed dovecot with MySQL in which the users are stored. Now I want to separate IMAP-Users from POP3-Users. So I added two columns to the user table (imap / pop3) which indicates, whether the user has access to IMAP or not. In order to get dovecot recognizing this separation I put the auth-config into the two protocol-sections and wrote two different dovecot-sql.conf-files. In the dovecot-sql-pop3.conf the query searches for pop3=1 and in the dovecot-sql-imap.conf it searches for imap=1. Done that, I expected POP3-Only-Users getting an error while trying to connect to the IMAP-service. But dovecot first tries to authenticate for IMAP and then uses the POP3-auth as fallback. How can I do this separation? Thanks a lot, Morton -- View this message in context: http://www.nabble.com/Different-protocols-with-different-auth-types-tp22085… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] ACL plugin when file in Maildir is not a directory
by Thomas Hummel 20 Feb '09

20 Feb '09

Hello Timo, On a production (by that I mean many users) dovecot-1.1.8/Maidir server where ACL plugin has been enabled, I ran on a log verbosity problem : For some reason (in fact, due to mbox -> Maildir migration script), some people have in their Maildir a .procmail.logfile file. The problem is that dovecot (or the ACL plugin) wants to find a dovecot-acl file in what it would like to be a directory, and then complains : dovecot: IMAP(xxxxxxxx): open(/courriel/boites/xxxxxxxx/.procmail.logfile/dovecot-acl) failed: Not a directory Such a behavior makes the log file grow too much too quickly. Note that my setup regarding log verbosity is at its minimal/default (except for proctitle) : verbose_ssl = no verbose_proctitle = yes auth_verbose = no mail_debug = no auth_debug = no auth_debug_passwords = no One more thing : would I have a log (or in what verbosity setup would I have one) line complaining about no-acl in the system wide acl directory : acl = vfile:/opt/dovecot/dovecot-acls:cache_secs=300 as a matter of fact, /opt/dovecot/dovecot-acls is empty for me (I don't need it for now). thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] v1.2 can't set ACL to empty string
by Sascha Wilde 20 Feb '09

20 Feb '09

Hi *, according to RfC4314 the rights argument to the setacl command might be an empty string ("zero right characters"): The third argument is a string containing an optional plus ("+") or minus ("-") prefix, followed by zero or more rights characters. existing clients (horde in particular) actually use this to remove all rights from an user. Currently dovecot 1.2 does not accept an empty rights string as argument to setacl. Bernhard Herzog will look into this. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Autocreate plugin
by Harry Lachanas 20 Feb '09

20 Feb '09

I've tried to use the autocreate plugin in order to autosubscribe users to public namespaces. namespace public { prefix = Public2/ separator = / location = maildir:/var/Public2:INDEX=~/Maildir/p-idx:CONTROL=~/Maildir/p-crtl hidden=no subscriptions=no inbox = no list=no } with plugin { autocreate = Spam autosubscribe = Spam autosubscribe1 = Public2/News autosubscribe2 = Public2/Shorewall } the plugin works alright with the Spam maildir, but not with the namespaces. Is this possible ??? Thanks Harry.

[Dovecot] Effects of going read-only on dovecot & pop/imap clients
by Mark Zealey 19 Feb '09

19 Feb '09

Hi all, We need to set our filestore to read-only for quite a while, and I want to mitigate the effects for our clients. First issue; dovecot. If we just change the nfs mounts to read-only, dovecot complains: 2009-02-19T14:03:19+00:00 mail2 dovecot: pop3-login: Login: user=<test2(a)markandruth.co.uk>, method=PLAIN, rip=10.15.10.95, lip=10.15.10.102:11002 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): open() failed with file /var/spool/mail/supplier_2/ma/rk/an/markandruth.co.uk/te/st/2_/test2/Mai ldir/dovecot.index.log: Read-only file system 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): open(/var/spool/mail/supplier_2/ma/rk/an/markandruth.co.uk/te/st/2_/test 2/Maildir/dovecot-uidlist.lock) failed: Read-only file system 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): file_dotlock_create(/var/spool/mail/supplier_2/ma/rk/an/markandruth.co.u k/te/st/2_/test2/Maildir/dovecot-uidlist) failed: Read-only file system 2009-02-19T14:03:19+00:00 mail2 dovecot: POP3(test2(a)markandruth.co.uk): Couldn't init INBOX: Internal error occurred.

Is there any way to make dovecot just do as much as it can under the circumstances ie allow read access to mails? Also, has anyone got experience of how clients handle mailboxes being read-only? My guess is that pop clients would probably break and download the same messages over and over?

[Dovecot] limiting authentication failures
by Eric B. Schorvitz, Ph.D. 19 Feb '09

19 Feb '09

In my log files I occasionally get a huge number of Dovecot authentication failures (see clip below). I wanted to know if there's a way to limit the number of times an IP address can attempt to authenticate, if there's a way to have a timeout between attempted authentications, or if there is a way to limit authentication attempts by a specific username within a certain period of time. My current solution is to permanently block the specific IP, an IP range, or an entire country from accessing my server AFTER I notice the huge number of authentication failures. This is too ad-hoc a process and was hoping dovecot has something more proactive built in. Thank you in advance for spending time considering this inquiry, Eric --------------------- pam_unix Begin ------------------------ dovecot: Authentication Failures: rhost=::ffff:200.111.39.219 : 764 Time(s) root: 25 Time(s) mysql: 6 Time(s) smmsp: 6 Time(s) --SNIP-- Unknown Entries: check pass; user unknown: 764 Time(s) ---------------------- pam_unix End ------------------------- --------------------- Connections (secure-log) Begin ------------------------ **Unmatched Entries** dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user info --SNIP--

[Dovecot] sieve filters
by Ian P. Christian 19 Feb '09

19 Feb '09

Hi all, I'm trying to figure out a way of filtering mail from a commercial anti-spam platform. Unfortunately you need to compare part of one header against part of another header. I figured I could solve this using sieve variables and pattern matching, however I'm having little luck and don't know how to debug sieve issues. # example headers: must compare 0.00799 against 1:0000 (the 2nd number in the 2nd header) # X-pstn-levels: (S: 0.00799/98.42547 CV:99.9000 FC:95.5390 LC:95.5390 R:95.9108 P:95.9108 M:97.0282 C:98.6951 ) # X-pstn-settings: 3 (1.0000:1.0000) s cv gt3 gt2 gt1 r p m c if header :matches "X-pstn-levels" "(S: */*" { set "score" "${1}"; if header :matches "X-pstn-settings" " ? (*:*) *" { fileinto "somewhere"; } } The first if appears to match, as if I move the fileinto up there it works - however it doesn't work as it shown here. Can anyone suggest why? Can I achieve what I'm trying to do with sieve? How can I go about debugging scripts? Thanks, Ian

[Dovecot] kerberos trying to obtain credentials for wrong machine
by Nikolay Shopik 18 Feb '09

18 Feb '09

Hi, I'm currently trying to configure Dovecot to use kerberos. My KDC is Windows 2003 and I successful generated keytab file for Dovecot machine. Problem is when I'm trying to use GSSAPI it told me Obtaining credentials for imap@debian5 - and of course this fails because debian5 isn't KDC, it should look for imap/debian5.inblock.local(a)INBLOCK.LOCAL. What I'm missing?

[Dovecot] Time moved backwards ....
by Harry Lachanas 18 Feb '09

18 Feb '09

OK.. So I synced the clock.... and got .... dovecot: Time just moved backwards by 1 seconds. I'll sleep now until we're back in present. http://wiki.dovecot.org/TimeMovedBackwards ( The first time I did this the clock moved backwards 2 hours after a timezone change and dovecot suicided ) I think I understand the concept ... However a mail server should probably be synchronized to the local time ..... Suggestions ...??? Harry.

[Dovecot] mbox snarf plugin + idle
by Jonathan Siegle 18 Feb '09

18 Feb '09

I'm having a problem with mbox snarf not looking at /var/spool/mail/ when in idle mode thus never giving me a RECENT line even though there are new messages in /var/spool/mail/ . Here are the imap commands to reproduce the problem: 1 login userid password 2 select inbox 3 idle When I run "select inbox" it does see my messages in /var/spool/mail/ and moves them over fine. When I truss the process, I see it only running stat calls on my "mbox- snarf" file. To get new messages I issue DONE, CLOSE, and SELECT INBOX.

you're using maildir? (I only ask because I am). In that case, no making the change doesn't require changes in the mailboxes.

[Dovecot] Maildir hierarchy sep bug ?
by Thomas Hummel 17 Feb '09

17 Feb '09

Hello Timo, I'm experiencing the following different behaviors with dovecot-1.1.8/Maildir. My Maildir hierarchy separator is the "." (dot) character. My namespaces, when I use them, separator is "/". When I run the server without any namespaces, I can create mailboxes named something like first.name which, of course, are shown to the client as first/ (non selectionnable) first/name For instance in Mutt, if I save a message (the "s" key) from first.name(a)some.domain dovecot happilly creates the .first.name/ Maildir But if I create a public Namespace, then I have to create a private default namespace as well and the server doesn't behave the same way : They're set up like this : namespace private { separator = / prefix = location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot/indexes/%1u/%u inbox = yes hidden = no list = yes subscriptions = yes } namespace public { separator = / prefix = '#Foo/' location = maildir:/courriel/boites/public/foo inbox = no hidden = yes list = no subscriptions = no } Then users cannot create mailboxes with a dot in it : Character not allowed in mailbox name: '.' which seems normal but can be confusing since, a user used to saving his mail in first.name (in Mutt for instance) wouldn't be able to do so anymore if the server goes from the first to the second setting described above. Granted, a user which does so, probably doesn't do what he thinks he does (he probably thinks he save his message in a folder named "first.name" while instead he actually saves it in a subfolder of "first" named "name"). Still it can be confusing. Is that difference of behavior normal ? Which is the correct behavior ? And is there still no way (except to patch the source) to allow dots in mailbox names in Maildir ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] dbox redesign
by Timo Sirainen 17 Feb '09

17 Feb '09

This is about how to implement multiple msgs/file dbox format. The current v1.1's one msg/file design would stay pretty much the same and it would be compatible with this new design. dbox directories with multiple msgs/file would be like: ~/dbox/storage/ has the actual mail data for all mailboxes ~/dbox/mailboxes/ has subdirectories containing mailboxes and their indexes Also since dbox supports already the single msg per file, those files would be stored in the mailboxes/ directory. So the idea would be that either you use multiple msgs per file using a global storage, or you use single msg per file without a global storage (or it's also possible to be in a mixed setup with some mails in storage/ and some in mailboxes/, mainly to allow migration between those configurations). The storage/ directory would have a new "map index" which is a regular dovecot index (dovecot.index and dovecot.index.log). So the mailbox index would point to mails using an intermediary "map UID". This way if mails are moved to another file only the map index needs to be updated. GUID would be a globally unique 128 bit ID for messages. So if map indexes get corrupted for any reason it's possible to rebuild it by finding the mails using GUIDs. v1.1 dbox has this "dbox.index" file which I was originally planning on using with multiple msgs/file. It had complex file range locking stuff. Now I'm thinking that it's pretty much useless. The only reason for its existence with the new design is for listing metadata for files converted from Maildir. Map index record would contain: - 32 bit map UID - 8 bit flags (MAIL_DELETED flag = message marked as expunged) - 8 bit unused wasted space - 16 bit refcount - 32 bit file sequence - 32 bit file offset --> total 128 bits/msg Mailbox index: - IMAP UID, flags, keywords, etc. - 32 bit map UID - 128 bit GUID dbox file metadata: - 128 bit GUID - size, vsize, received time, saved time, etc. - initial mailbox name (if all indexes get trashed, we can still figure out at least one mailbox where to put the mail. copies would get lost though.) (- no map UID, no imap UID) How to save a message with multiple msgs/file: 1. Find dbox file where to append to: 1.1. Look up the last message from map index 1.2. Is the file "too old"? (or doesn't exist at all) - Yes -> Create new dbox file 1.3. Is the file "too large"? - Yes -> Look at the previous file (one sequence less) and goto 1.2. 1.4. Try to lock the file. - Fail -> Look at prev file and goto 1.2. Now we have a locked/new dbox file where we can write to. Because 1.4. step only tries to lock the file, there's no waiting on locks. This also means that if e.g. two processes are writing new messages rapidly they may be appending actively to two different files. I don't think that's a problem, better than waiting for locks. 2a) We're using an existing file and we need to find the append offset. Since we found the file by finding the last msg in the file, we also know the last message's offset. I wasn't really planning on saving the message sizes in the index file, so to get the append offset I guess it needs to do an extra read on the last msg's header to find the size and skip over it. Hmm. Or would it be less disk I/O to store the size on the index so it could be found directly? I'm not really sure.. In any case, after we find the append offset, check to see if it's at EOF. If not, that means that either another process just saved a new message there or a process crashed previously and left garbage lying around. Refresh the map index to see if this file+offset exists in it. If not, truncate the file and just continue writing there. If it exists, figure out the new append offset and see again if the file limit would be reached. If the file would become too large, unlock the file and goto step 1. 2b) We're writing to a new file. No need to worry about anything in 2a) 3. Write the message and its metadata to dbox file (including generated 128 bit GUID). 4. Assign map UIDs for the written mails and write APPEND records to map index's transaction log. The record would contain the map UID, file seq, offset, refcount=1. The transaction is saved with a "weak" flag (wonder if there's a better name for this) and its offset is remembered. - If we're creating a new dbox file, it's assigned the file seq and rename()d to the final file name while the map index is locked. 5. Write APPEND record to mailbox index's transaction log with IMAP UID, map UID and GUID (and flags, keywords, etc). 6. Write "commit offset=x" record where x is the offset remembered in step 4. This marks the 4's weak transaction as being fully finished. 7. dbox file is unlocked (if we weren't creating a new file). When reading the index and we see a weak transaction without a commit record, call a resolve() function in dbox code. It finds the dbox file in the weak transaction and tries to lock it. If it can't lock it, it (probably) means that there's still a process that's going to finish the save. If a locking succeeded, run a fixup code that goes through all files that are referenced in weak transactions and makes sure all the refcounts and such are valid. Then it writes commit records for each such transaction. Copying can be done by locking source dbox file, writing a weak "refcount++" transaction and continuing from saving step 5. The only step I can think of where there's a small problem is if data is written to dbox file, then process dies, but no saving is attempted to the same file later. The data is left there as garbage until maybe some day later when a message is expunged from that file and cleanup code notices that there's extra data. I thought about reordering steps so that the records are written to map index first, but that's less efficient when writing multiple messages, because each one would need to be saved separately to the map index (where each save would be lock + fstat (+ read) + write + unlock). This is probably a rare problem which doesn't really matter.. Expunging: The "expunge" and "cleanup to remove deleted space" are separate steps. Preferably the cleanup would be done when the server is "less busy", but I guess it could also be configured to happen either immediately or during logout (or once an hour or so). 1. Write "want to expunge" record to mailbox's transaction log. 2. Write a weak "refcount--" to map index's transaction log. 3. Write "expunged" record to mailbox's transaction log. 4. Write "commit" for the weak refcount--. (The two-stage want-to-expunge(1)/expunged(3) is already done for maildir/mbox also.) I was also thinking maybe this could be just 3 steps without a weak transaction. Especially since without a fsync() between 2 and 3 there's really no guarantee about the order in which 2 and 3 happen. And fsync()s are kind of annoying. But then again if that isn't done and it crashes between 2 and 3 the expunge is tried again later which now decrements the refcount again. If the message's original refcount was 1 it would now be negative. That's not really a problem. More problematic is if the message had been copied to another mailbox and refcount=2, now the refcount would be 0 and the message in the other mailbox would get unexpectedly lost. Not good. Space deletion cleanup: 1. Check from map index header to see there are any refcount=0 mails. Although having this step probably requires some annoying dbox-specific code in index handling code. I guess I'll have to see later if there's a non-horribly-ugly way to do this. 2. Go through all records in the map index. Get a list of files that have refcount=0 records. Also make a copy of file seq+offsets and sort them (so at step 3 we can easily find what mails exist). 3. For each file that has refcount=0 records: 3.1. Try to lock the file. -> Fail: Skip to next file. Either someone's appending to it or cleaning it up already. 3.2. Refresh map index. Add any newly added records to the sorted records list (rare). 3.2. Find the first refcount=0 mail. 3.3. Copy all mails after that with refcount>0 to a new file. 3.4. Lock map index, assign new file seq for the new file, rename() it, for each mail we just copied, using a weak transaction write the seq +offset updates to map index's transaction log. Unlock map index. 3.5. Depending on if first refcount=0 mail was the first mail, either unlink() the file or ftruncate() it. 3.6. Write "commit" record to finish the weak transaction. That's a bit inefficient when cleaning up multiple dbox files, but I'm not sure if there's a much better way unless the map index is locked for the entire time. Since the copying might take a while, a long map index lock is bad since it prevents messages from being saved. Reading mails can be done without locking. But since a file can be truncated unexpectedly, the code must be able to find the new file and offset in that situation and continue reading from there. If the message we were reading was just expunged+cleaned up, the client will have to be just disconnected. Since the cleanup shouldn't normally happen immediately after expunge, this should happen rarely/never. Oh and about all these new temp files that are created. When dbox is opened the dir is stat()ed and if its atime is older than 1 week (currently hardcoded) it readdir()s through the dir to see if there are any old temp* files and then unlinks them. With the new design flags/keywords would never be written to actual dbox files. This helps with backups and also avoids the horribleness of having to increase metadata area. To avoid complete data loss due to index corruption (which really shouldn't be happening nowadays), the indexes are also once in a while backed up to e.g. dovecot.index.backup file. If Dovecot detects missing/broken index, it uses this backup copy to rebuild the index as well as it can. I'm also wondering if it's better for each mailbox to have its separate dovecot.index.cache file or if there should be one cache file for the map index. The upside with one index is that if a mail is copied there's no need to duplicate its cached data. The downside is that I'm worried it would cause more disk I/O, since mailboxes are typically accessed separately, so it might be better that the cache data for one mailbox is stored together rather than all around one bigger cache file.

[Dovecot] Changing level an error logs at
by Thomas M Goerger 16 Feb '09

16 Feb '09

Hi, I'd like to change the log levels of a few of the errors that Dovecot throws. Our servers throw errors at the console above the 'Error' level, and there are a few that I'd like to change to 'Warn' so that they don't do so. Has anyone out there attempted this and can give me a few pointers? Or is there a doc somewhere about how to do this?

I remember last year we discussed Dovecot replication a bit on this list, e.g. http://www.dovecot.org/list/dovecot/2008-May/030446.html . Has there been any development related to this, and can I help at all? The more I think about the hacks I'm employing to synchronize mail, the more I realize I want this. So hopefully I can put either some money or some time where my mouth is. -- Asheesh. -- Its name is Public Opinion. It is held in reverence. It settles everything.

[Dovecot] unkillable imap process(es) with high CPU-usage
by Arno Wald 15 Feb '09

15 Feb '09

Hello, I am having a problem with my dovecot-daemon. It is forking one or more (I saw up to perhaps 8 of them) imap processes under my user name. These processes are consuming a lot of CPU time and are not killable: > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 8616 arno 20 0 2900 1600 1204 R 98 0.2 1196:38 imap Stopping dovecot does not quit these processes. Killing them (even "kill -9" as root) is not possible. The only solution to get rid of them is to reboot. I have found a mailing list post of one who seemed to have the same problem. He solved it by upgrading to version 1.1. But in my case this did not help. Is this a known problem? What could I check or do? My system: very up to date debian/sid (sidux) kernel 2.6.27-8.slh.1-sidux-686 CPU: Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz Filesystem: ext3fs tried dovecot from sid: 1:1.0.15-2.3 tried dovecot from experimental: 1:1.1.2-3 My dovecot.conf is the original debian configuration with only one line changed into: protocols = imaps # dovecot -n # 1.1.2: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail auth default: passdb: driver: pam userdb: driver: passwd I am using dovecot locally on my system with me as the only user. As client I am using thunderbird alias icedove 2.0.0.17-1. Icedove retrieves the Mails from another imap server and sorts them into Maildir-folders in dovecot. I do not know when the imap-process are going mad. It happens after the system (and the mail-client) is up for a while. Do you need more information? Thanks, Arno

[Dovecot] great disappearing email mystery
by dhottinger＠harrisonburg.k12.va.us 14 Feb '09

14 Feb '09

Have there been any issues with dovecot and using outlook express (imap) as an email client? I have had a couple of users come up with random missing emails. Im trying to figure out if it is user error, or something wacky in my mailserver. I cant find anything telling in maillog files or my messages. Dovecot version is 1.0.3. Its ok to reply to me, I get list messages digest. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

We are having the same problem. It's not a problem with imap, only with pop3. We're using deliver as the MDA. We're also using flock() locking for the mbox: is that what everyone else is using as well? Migrating our servers to maildir globally is also not an option for us. In some cases, even convincing customers to use IMAP isn't going to work. One problem which might be making this worse than it needs to be, is the fact that mbox_lock_flock in mbox-lock.c is not using a blocking flock(); instead, it's polling for a non-blocking lock. This technique can cause lock starvation, if another process is dropping the lock and picking it back up again frequently: other processes will only see the lock as being available if they happen to poll for the lock at just the right instant. A better technique to use here, if it's adequately cross-platform, would be to set an alarm() for the max_wait_time, and use a blocking flock(). If the alarm times out and you don't have a lock, it's a timeout. In the meantime, you're guaranteed to eventually get the lock, if it is dropped. That said: I'm not sure whether this will solve our problem in practice. Why doesn't this happen with imap? Why can't we make pop3 do what imap does? Even if it's inefficient, it's better than hanging all incoming mail delivery while deliver eats up our local concurrency limits. Thanks! Alan Ferrency pair Networks, Inc. alan(a)pair.com

[Dovecot] Smooth mailbox to maildir migration
by Luciano Mannucci 14 Feb '09

14 Feb '09

Hi all, I have a postfix+procmail+dovecot installation, now running basicaly on pop3 hence mailbox format, with few thousand users and less than twenty gigabytes mail. I need to move all of them to maildir, to take advantage of IMAP subfolders that do not work with mbox format (so I'm told :). Of course I cannot safely stop the service for more than a bunch of seconds... What I'm about to do: create a second dovecot instance to cope with imap client configured for maildir (and possibly pop3 on another port for those using both), which means a dovecot launched with -c /path/to/alternate.conf and a new /etc/init.d/dovecot2-theRevenge having the proper -i option given to startproc in order to make it ignore the other instance. for each user: convert the mailbox with some sort of mb2mb (which is the better one?) create a .procmailrc with a proper DEFAULT= bearing the magic trailing slash indicating maildir to procmail for each converted user. And I'm done... Have I forgotten something? Is there a better way? Any one else tryed such a thing? Cheers to all, luciano. -- /"\ /Via A.

[Dovecot] Weird Dovecot 1.1.6 + pop3s certificate issues
by Bernhard Schmidt 14 Feb '09

14 Feb '09

Hello everyone, I've been asked by a colleague to have a look at some extremely weird dovecot SSL issue they are seeing on one of the student mailservers. They are running dovecot 1.1.6 (yes, I know, a bit old ...) on SLES 10.2 x86_64 with imap(+starttls), imaps, pop3(+starttls) and pop3s enabled. Every couple of weeks the pop3s and pop3+starttls part bail out out. Clients can't connect, when you try openssl s_client you get this: 15960:error:0407006A:rsa routines:RSA_padding_check_PKCS1_type_1:block type is not 01:rsa_pk1.c:100: 15960:error:04067072:rsa routines:RSA_EAY_PUBLIC_DECRYPT:padding check failed:rsa_eay.c:699: 15960:error:1408D07B:SSL routines:SSL3_GET_KEY_EXCHANGE:bad signature:s3_clnt.c:1414: server logs don't show much except for various SSL_accept() errors, including TLS handshaking: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac TLS handshaking: SSL_accept() syscall failed: Connection reset by peer TLS handshaking: SSL_accept() failed: error:1409441B:SSL routines:SSL3_READ_BYTES:tlsv1 alert decrypt error imaps and imap+starttls work fine during the whole time (and always have), although they are much more used. Restarting dovecot fixes the issue for a couple of weeks. Does anyone have an idea where to start debugging? As far as I understand the whole SSL_accept() thing is a giant blackbox for Dovecot, but how comes it only affects POP3? dovecot -n (paths and addresses altered, not sure how much I can reveal without getting shot): # 1.1.6: /mnt//usr/local/etc/dovecot.conf # OS: Linux 2.6.16.60-0.25-smp x86_64 SUSE Linux Enterprise Server 10 # (x86_64) protocols: imap imaps pop3 pop3s listen(default): [ipv6]:143, ipv4:143 listen(imap): [ipv6]:143, ipv4:143 listen(pop3): [ipv6]:110, ipv4:110 ssl_listen(default): [ipv6]:993, ipv4:993 ssl_listen(imap): [ipv6]:993, ipv4:993 ssl_listen(pop3): [ipv6]:995, ipv4:995 disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /mnt//usr/local/libexec/dovecot/imap-login login_executable(imap): /mnt//usr/local/libexec/dovecot/imap-login login_executable(pop3): /mnt//usr/local/libexec/dovecot/pop3-login login_process_per_connection: no login_max_connections: 128 max_mail_processes: 2500 mail_uid: campus mail_gid: lmu mail_location: maildir:~/Maildir:INDEX=/home/something/indexes/%-1.1n/%n mmap_disable: yes mail_nfs_index: yes mail_executable(default): /mnt//usr/local/libexec/dovecot/imap mail_executable(imap): /mnt//usr/local/libexec/dovecot/imap mail_executable(pop3): /mnt//usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /mnt//usr/local/lib/dovecot/imap mail_plugin_dir(imap): /mnt//usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /mnt//usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: worker_max_request_count: 500 passdb: driver: ldap args: /mnt//usr/local/etc/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: ldap args: /mnt//usr/local/etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: campus group: lmu plugin: quota: maildir quota_rule: Trash:ignore quota_rule2: *:storage=512M Anyone having an idea? bernhard

Re: [Dovecot] Dovecot-antispam does not work
by Jehan Pagès 14 Feb '09

14 Feb '09

Hi all, just to say that finally the patch of Marcin worked great. Just my configuration is different from yours to get it work: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items antispam_spam = SPAM;Junk antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --client;--source=error;--user;%u antispam_mail_tmpdir = /tmp The difference here is in the syntax. You write "--user=somemail" though in the manual, it is written "--user somemail". But also you were proposing 2 lines "antispam_dspam_args" though in all my tests, when I was doing such a thing, the second line seemed to override the first (in the launch logs, only the second line was displayed, so I guess...). Are you sure that it works exactly the way you intend to, Marcin? And that the "--source=error" (your first line) is indeed added as a parameter to the call of dspam? For the patch to the dovecot-antispam, probably it should not be integrated "as is", but I guess that the return code of call_dspam function must probably be checked and fixed if the call can succeed but still give a failure return code. I set Johannes as a main recipient, maybe you will see this email. Bye and thanks all.

[Dovecot] Production server migration from mbox to maildir ( need advice )
by Frank Bonnet 13 Feb '09

13 Feb '09

Hello I'm going to change the raid array of my mailhub in fews days/weeks and I wonder if it would be a good idea to take the opportunity of this migration to also change the storage method from mailbox to maildir. I've never used maildir on my production server only on small satellites. So I really need advice of admins that use maildir format on prod servers. My server has approx 3500 users/mailboxes that is approx 450 Gb of data. The OS is Debian etch amd64 but could change also during the migration Opensuse X86_64, CAOS-NSA, FreeBSD 64 are some options. Any infos/experiences welcome, I'll summarize answers. Thanks a lot.

[Dovecot] Bynari Insight connector
by Maarten Bezemer 13 Feb '09

Hi, Since IMAP support in Outlook is 'somewhat broken', and Bynari has some promising specifications on their website, I might want to try their product. Does anyone here have any experience with their software? Would you recommend it? Or maybe point me at alternatives? (If there are any.. aside from ditching Outlook of course :-P ) Regards, Maarten Bezemer

Re: [Dovecot] Mapping usernames [RESOLVED]

Resolved. For others, this is the simple solution which works for me: /etc/dovecot.conf: auth default { userdb passwd-file { args = /etc/passwd } passdb passwd-file { args = scheme="MD5-CRYPT" /etc/dovecot.passwd } } /etc/dovecot.passwd: bob@vhost.com:$1$yAOjs09l$...::::::userdb_user=vabc_bob (the encrypted password "$1$yAOjs09l$..." comes from /etc/shadow) /etc/passwd: vabc_bob:x:20838:2362:bob:/home/mailusers/vabc_bob:/sbin/nologin "abc" could also be the domain ("vhost"), but this might be too large for really long domain names. So we rather use a short unique prefix for each domain.

[Dovecot] file name missing component in error message
by Mike Abbott 13 Feb '09

13 Feb '09

Hi, we occasionally see this error message from maildir_mail_set_cache_corrupted(): "Maildir filename has wrong W value: %s/%s" but the path it prints is missing a component, specifically, the new/cur/tmp component. For example: /Volumes/Spool/user/maildir/12345.M123P123.example.com.... should be /Volumes/Spool/user/maildir/cur/12345.M123P123.example.com.... This is using dovecot-1.1.10. Now I just have to figure out why the file is corrupted in the first place.

[Dovecot] quota - implement via dovecot or postfix? which is easier ?
by Linux Advocate 13 Feb '09

13 Feb '09

Guys, i m new to dovecot. I m setting up a new mailserver and planning to run dovecot and postfix of a centos 5.2 box. I have been reading of quota management from various sources and understand that mail box quota can be implemented either thru postfix ( with vda patch ) or thru dovecot. i rather not patch postfix and m therefore leaning towards quota via dovecot. But after reading some posts ,etc, it seems that the information on the dovecot wiki is inaccurate. A.Any comments on this? B. Am i right in concluding that its easier and better in the long run to implement and enforce quotas thru dovecot instead of postfix? C. The right instructions for implementing quota thru dovecot? Regards, marco.

[Dovecot] Released Sieve v0.1.3 and ManageSieve v0.11.3 for Dovecot v1.2.beta1
by Stephan Bosch 13 Feb '09

13 Feb '09

Hello Dovecot users, It has been about two months since the last release of the new Sieve implementation and the ManageSieve service for Dovecot v1.2. Therefore, this release contains quite a few changes. It adds new sieve features like the enotify extension and multiscript support. Also, quite a few (user-reported) bugs were fixed since the last release. Changelog Sieve v0.1.3: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= 1.2.beta1 * Made mail address comparison fully case-insensitive. This is particularly noticeable for the :addresses argument of the vacation command. + Finished enotify extension. Currently, only the mailto notification method is implemented. All still needs to be tested thoroughly. + Implemented multiscript support. It is now possible to execute multiple Sieve scripts sequentially. Administrator-controlled scripts can be executed before and after the user's script. Still needs to be tested thoroughly. + Implemented support for configuring the available Sieve extensions. + Made the subaddress extension (partially) configurable using the sieve_subaddress_sep setting, which allows specifying a (multi-charater) separator other than '+'. + Compiler now warns about invalid header field names used for the header and address tests. + Vacation extension now properly generates a References header for the response message. + Added testing of basic result execution to the test suite. Also added support for testing the outgoing messages produced by the Sieve interpreter. + Included execution of the actual result in the sieve-test command line tool. The undocumented sieve-exec tool that existed for this is now removed as planned. + Added support for the now obsolete 'imapflags' extension for backwards compatibility with CMUSieve. This also implements the mark/unmark commands. - Fixed bugs in the regex extension: 1) if an optional match value did not in fact match, subsequent match values would get unexpected indexes. 2) fixed segfault bug occuring when regex is freed. - Fixed bug in the use of the :from agrument for the vacation command. If this address included a phrase part, the response would not be a valid RFC822 message. - Plugged a theoretical security hole occuring when a directory is opened as a Sieve binary. - Cleaned up and fixed various log messages. - Fixed bug in the outgoing address verification. Addresses ending in ',' were erroneously accepted. Changelog ManageSieve v0.11.3: * Changed the SASL service name from "managesieve" into "sieve" as required in the protocol specification. Don't forget to adjust your configuration if your authentication mechanism depends on this service name. * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.beta1. * Adapted to changes in the new Sieve implementation, making this release dependent on Dovecot Sieve >= v0.1.3 if used. The old cmusieve plugin is still supported. + Implemented making the SIEVE and NOTIFY capability fully dynamic, meaning that the sieve_extensions setting that was introduced for the new Sieve plugin properly affects the ManageSieve daemon as well. + Added support for the CHECKSCRIPT command. In terms of the supported commands, the ManageSieve daemon now complies with protocol VERSION 1.0 as listed in the CAPABILITY response. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed handling of ~/ in use of mail-data for script location. - Fixed small problems in the login proxy support. The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.3.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.3.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.3.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.3.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.beta1-managesieve-0.11.3.di… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.beta1-managesieve-0.11.3.di… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] delivering to folder based on recipient_delimiter?
by dovecot＠corwyn.net 12 Feb '09

12 Feb '09

I'm currently running postfix + dovecot, with virtual users In postfix I have set recipient_delimiter = + so that postfix accepts mail for user(a)example.com, user+foo(a)example.com, and user+spam(a)example.com all deliver to inbox. what I would like is to have email directed to user+foo(a)example.com delivered to the IMAP folder foo (and, in the context of amavisd, have amavis configured for recipient_delimited, and add addr_extension_spam_maps add +spam to each mail identified as spam, and thus the mail would go to the spam folder on delivery. The postfix guys say I should be able to do this. can someone point me to how to implement this with dovecot? (as I don't see how to even start). Thx Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Can't remove folder (no thunderbird issue)
by Jan Niggemann 12 Feb '09

12 Feb '09

Hi, first of all: yes, I already dug the internet but didn't find a solution - that's why I'm asking you. My provider uses dovecot, although I can't tell you more about the version - sorry. Mail is stored in mbox format. My trouble: I was unable to create subfolders and googled a bit. A proposed solution was to append a slash at the end of the folder name. I used Thunderbird to create a folder and called it "test/" (yes, with a slash). Now, in both, Thunderbird and Mulberry, I'm unable to delete that folder (that contains neither messages nor subfolders). Mulberry doesn't give an error message, and in Thunderbird I can't find an option to remove this folder (no matter if subscribed or not). My provider uses roundcube as a webmail interface. Trying to delete the folder there seems to work OK, but after refreshing the folder-view it re-appears. I have no (ssh|telnet|...) access to the server, so I can't remove the folder using the shell.. Do I have other options than calling support? Thank you already jan

[Dovecot] sendmail smtp auth using client socket
by EQX 12 Feb '09

12 Feb '09

Hi list I searched the net, but could not find something related. Is it possible to export the client socket to sendmail for smtp auth? What would be the sendmail.mc configuration for this? #client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. #path = /var/spool/postfix/private/auth #mode = 0660 #user = postfix #group = postfix #} It can also be the other way round: can Dovecot use Cyrus SASL for user authentication? I need to use sendmail, ip based solutions like pop-before-smtp or poprelay are not an option. Thanks, Mike

[Dovecot] Mapping usernames
by Henry 12 Feb '09

12 Feb '09

Greets, We're using Dovecot 1.0.7 (which comes with CentOS 5.x). I have successfully configured dovecot to change a username from abc(a)123.com to realname1_abc for a machine which only has a single domain (using auth_username_format=realname1_%Ln). However, I'm pulling my hair out trying to get dovecot to handle multiple domains (the machine has existing /etc/passwd /etc/shadow and /etc/mail/virtusertable users). On an older machine, I simply hacked the source code to perform a berkeley DB lookup in /etc/mail/virtusertable.db for the realname[a-z0-9]_xx. This time round, though, I'm trying to do this cleanly. I've been reading the docs/wiki/etc but I now can't see the forest for the trees. This is what I've got so far: In /etc/dovecot.conf: ... auth default { userdb passwd-file { args = /etc/dovecot.passwd } passdb passwd-file { args = /etc/shadow #args = /etc/dovecot.passwd } } /etc/dovecot.passwd contains: realnamea_abc:{PLAIN-MD5}$1$Vjkfhaa....::::::userdb_user=abc@123.com I've been fiddling around blindly with all kinds of settings in userdb {} above, but I always get the error: "passwd-file(abc@123.com,::ffff:127.0.0.1): unknown user", amongst others. In a nutshell, I want to allow a user to login with abc(a)123.com, this name must be mapped to a real system user (eg, using /etc/dovecot.passwd), then authenticated against /etc/shadow or the MD5 password in /etc/dovecot.passwd I would appreciate any kind of pointers or advise here. It would have been nice if vpopmail allowed me to call an external perl script where I could perform the username mapping, but alas, this is not possible.

[Dovecot] v1.2: Can't subscribe to shared user folder
by Sascha Wilde 12 Feb '09

12 Feb '09

Hi *, I stumbled across a small bug (missing feature?) in the new shared name space stuff: a001 list "" "*" * LIST (\Noselect \HasChildren) "/" "user" * LIST (\Noselect \HasChildren) "/" "user/bob(a)example.com" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/bar" * LIST (\HasNoChildren) "/" "user/bob(a)example.com/brooklebookle" * LIST (\HasNoChildren) "/" "user/bob(a)example.com/foobar" a001 OK List completed. a002 lsub "" "*" a002 OK Lsub completed. a003 subscribe "user/bob(a)example.com/foobar" a003 NO Unknown subscription namespace. I'm quite sure this once worked in our original code (but of cause I could be mistaken). cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] (Somewhat urgent) Problem with maildir++ quota
by Santiago Romero 12 Feb '09

12 Feb '09

Hi. I have an strange problem with dovecot's maildir quota and postfix. I've tested quota and it works fine but sometimes there are users that having their Maildir/ empty, they trigger the "quota exceeded" message when someone sends email to them. Some config / version info: ### Versions: ii dovecot-common 1:1.0.10-1ubuntu5.1 ii dovecot-imapd 1:1.0.10-1ubuntu5.1 ii dovecot-pop3d 1:1.0.10-1ubuntu5.1 ### From dovecot.conf: (...) # SQL database <doc/wiki/AuthDatabase.SQL.txt> userdb sql { # Path for SQL configuration file args = /etc/dovecot/dovecot-mysql.conf } (...) dict { #quota = mysql:/etc/dovecot-dict-quota.conf } (...) plugin { quota = maildir:storage=51200 } ### dovecot-mysql.conf (splitted to be readable): user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ### Database "mailbox" record example: | prueba(a)domain.com | Password | prueba | domain.com/prueba/ | 51200000 | domain.com | 2009-02-02 10:01:24 | 2009-02-02 10:07:46 | 1 | The symptons: users are working nicely, and quota works (If I create a new user and set it a quota of, say, 1MB, I can send him msgs until Maildir reachs 1MB, after that I get "quota exceeded" messages). But sometimes there are users with the Maildir empty that can't receive messages and trigger the "quota exceeded" warning. Users always download messages by POP. Removing "maildirsize" file in their folder fixes the problem. Also fixes it changing the quota to any value (maildirsize is then removed and recreated after a new message arrives for the user). Sometime that I don't know if it's strange is that I don't see "removing" messages in the maildirsize file after user downloads messages. I mean that I can't see "-1" lines in maildirsizes: # cat prueba/maildirsize 51200000S 0 0 615 1 1540 1 11446 1 46085 1 2623 1 21218 1 2815301 1 15110 1 21289 1 18330 1 (and so). Any idea of what's going on? Shouldn't appear "MSGSIZE -1" lines in maildirsize file to "restore" space in Maildir after POP RETRs? Currently I'm fixing the problem with a regular: # find /home/vmail/vhosts -name "maildirsize" -exec rm {} \; But there must exist a better solution (or maybe my config is wrong). Thanks a lot for any help. -- Santiago Romero

[Dovecot] Panic in dovecot 1.2.beta1
by Mark Sapiro 11 Feb '09

11 Feb '09

I tried Dovecot 1.2.beta1 yesterday. I had been using 1.1.11. I started getting "Panic: POP3(xxx): Trying to allocate 0 bytes" There are two kinds of pop3 users. In the attached log.txt file, user u1 is using a pop3 MUA. For users u2, u3, u4 and u5 fetchmail is coming through an ssh tunnel and retrieving their mail. u1 is able to interact normally with dovecot, but the fetchmail users encountered the panics in the log. dovecot -n is attached as dovecot-n.txt. At first I thought it was a locking issue as .lock files were being left behind, so I changed pop3_lock_session to no, and restarted dovecot, but this didn't help so I reverted to 2.1.11. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Adding new storage
by Romer Ventura 11 Feb '09

11 Feb '09

Hello, I am about to add more storage to the mail server and would like to know if it is as simple as it sounds..? I have: dovecot.conf mail_location: maildir:~/Maildir/ and /etc/dovecot/dovecot-ldap.conf with: user_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln/Maildir/ So all the mail gets stored at /home/vmail/%Ud/%Ln/Maildir/ so if i add a new volume to the VM lets say /dev/disk3 and mount it to /srv/ vmail and then change the user_attrs = sAMAccountName=mail=maildir:/ home/vmail/%Ud/%Ln/Maildir/ to user_attrs = sAMAccountName=mail=maildir:/srv/vmail/%Ud/%Ln/Maildir/ would it work with no problem..? I would also need to move all the mailboxes already in the old location... I just want to make sure before i do anything.. Thanks

[Dovecot] Understanding dovecot ACLs
by Achim Hut 11 Feb '09

11 Feb '09

Hello List I am running a Cyrus IMAP that needs to be replaced. Geting a Dovecot IMAP up and running was surprisingly simple. My configuration is close to Johnny Chaddas Howto at http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wi… Its a Dovecot 1.1.10 on FreeBSD 6.4 Anyway, while basic setup was easy, i stuck in a couple of details like quota, managesieve, etc. Actual major problem and showstoper is understanding the ACLs the confuses me. So i need a hint to be guided in the right direction. What i need is a scenario, where user1 can get (for example) full access to the folders of user2, read-only access to user3 etc. A real world example: Secretary has full access to the mailfolders of her boss, boss has read-only acces to the sales-department folder. My questions: 1) is the possible? 2) can it be done with dovecot-acl files? 3) Namespaces: is it enough to have the private namespace for the job or do i need another namespace? 4) if yes, how should this namespace look like? Thanks for the help Achim

[Dovecot] dovecot logs to audit.log not to maillog

Hello, I have a curious phenomenon. Dovecot logs normally to /var/log/maillog. If I restart my server, dovecot loggs to /var/log/audit/audit.log. If I restart dovecot, dovecot loggs to /var/log/maillog again. And I think, wenn logrotate is restarting, dovecot logs to audit.log. But I don't know why. Any Ideas? greetings Ralf

[Dovecot] mailing lists and Dovecot deliver (lda)
by Roderick A. Anderson 11 Feb '09

11 Feb '09

I'm trying to figure out a way, or if it is even possible, to use mailing list software (majordomo2) on a Postfix + Dovecot + virtual mailboxes system. And where I should be looking. The examples on the Postfix site don't seem to address a purely virtual mailboxes system and I haven't found anything about doing it with deliver. I think I'm at the wrong tree (Dovecot deliver) and should be pestering the Postfix list. FTR, I host some sites for not-for-profits and they have asked about setting up lists. So far I've dodged the question but would like to attempt it now. Thanks, Rod --

I thought about saying this in v1.2.beta1 release annoouncement, but looks like it'll take a few more days. So I've moved to Blacksburg, Virginia and I'm now working for Mailtrust the rest of this year. Here's some talk about it: http://mailtrust.com/blog (A bit stupid looking picture, but then again all my pictures seem to be that way so I didn't bother getting a new one taken.) And if it's not clear from that blog: Pretty much everything I do here will be Dovecot improvements that will be released as open source. Mailtrust has actually been paying for Dovecot features for about 3 years now.

[Dovecot] redelivered mail results in mail-forwarding-loop
by Reto Glauser 10 Feb '09

10 Feb '09

I try to redeliver mail for the following reason: Once in a while a user receives a mail which isn't correctly recognised as SPAM/HAM. He'll move the mail into a specific folder (say: retrain-as-spam/retrain-as-ham) and a script will retrain the mail. What I'd like to do is to redeliver the mail in order for correct (re)delivery (e.g. sieve scripts). Using sendmail to redeliver the mail I'm able to re-run the spam tests which will add it's SPAM headers and dovecot/sieve will be able to correctly file the message. I tried to just resend the mail: # /usr/sbin/sendmail -f foo@bar -v -oi foo@bar < mail but this results in a Diagnostic-Code: X-Postfix; delivery via dovecot: mail forwarding loop for foo@bar The problem is that the mail already has a "Delivered-To: foo@bar" line. The above is working when the "Delivered-To" line is being removed, and my question is if this can't be done automatically?

[Dovecot] Dovecot 1.1.11 segfaults on auth configuration error
by Sebastian Kayser 10 Feb '09

10 Feb '09

Hi, i have compiled & packaged Dovecot 1.1.11 on Solaris 8 x86 with Sun Studio 11 and installed the result on Solaris 10 x86 zone. When i now configure auth mechanisms other than "login" or "plain" while only providing pam as the passdb, Dovecot segfaults on startup. I know that my configuration is wrong here, but i guess this still qualifies as a bug. Remedy would be appreciated. # /opt/csw/sbin/dovecot -F dovecot: Feb 06 22:56:24 Info: dovecot v1.1.11 starting up dovecot: Feb 06 22:56:25 Error: child 26870 (auth) returned error 89 (Fatal failure) Segmentation Fault (core dumped) # /opt/SUNWspro/bin/dbx -f /opt/csw/sbin/dovecot core (dbx) where =>[1] hash_lookup(table = (nil), key = 0x68f6), line 159 in "hash.c" [2] child_process_lookup(pid = 26870), line 31 in "child-process.c" [3] log_it(log_io = 0x80b8598, line = 0x80b7d4a "DIGEST-MD5 mechanism can't be supported with given passdbs", continues = 0), line 129 in "log.c" [4] log_write_pending(log_io = 0x80b8598), line 52 in "log.c" [5] log_read(log_io = 0x80b8598), line 191 in "log.c" [6] log_deinit(), line 331 in "log.c" [7] auth_process_destroy(p = 0x80b86f8), line 357 in "auth-process.c" [8] auth_process_input(process = 0x80b86f8), line 244 in "auth-process.c" [9] io_loop_handler_run(ioloop = 0x80b3518), line 204 in "ioloop-poll.c" [10] io_loop_run(ioloop = 0x80b3518), line 336 in "ioloop.c" [11] main(argc = 2, argv = 0x80478dc), line 599 in "main.c" # /opt/csw/sbin/dovecot -n # 1.1.11: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc log_path: /dev/stderr login_dir: /var/opt/csw/run/dovecot/login login_executable: /opt/csw/libexec/dovecot/imap-login auth default: mechanisms: plain digest-md5 debug: yes passdb: driver: pam userdb: driver: passwd Please let me know in case there is any other information required to nail down the culprit.

[Dovecot] [patch] 'c' and 'd' in setacl
by Sascha Wilde 09 Feb '09

09 Feb '09

Hi Timo, Hi *, I just recognized that the new imap-acl plugin in dovecot 1.2 does not know the obsolete rights 'd' and 'c' when setting. According to RFC 4314 section 2.1.1.: If a client includes the "d" right in a rights list, then it MUST be treated as if the client had included every member of the "delete" right. and If a client includes the "c" right in a rights list, then it MUST be treated as if the client had included every member of the "create" right. Unfortunatly there are actually clients which depend on this behavior. I attached a rather rough[0] patch which implements this. cheers sascha [0] I don't like the use of static indexes witch imap_acl_letter_map but currently I wasn't able to decide on a more elegant solution. -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Rebuild folder listing?
by Roderick A. Anderson 09 Feb '09

09 Feb '09

I don't know what to call what I'm trying to do so I'll explain the situation. I had a total complete crash of the Linux-Vserver system that was hosting a Postfix+Dovecot guest with a three domains and 1-5 accounts per domain. Lots of mail though. Before it completely melted down I as able to get to the data (messages) and save them and the configuration files for both Dovecot and Postfix. I now have a replacement system up and running and have copied the directories onto it. I can log in to the accounts but I don't see the folders (I use Thunderbird as a MUA). Attempts to "subscribe" and "refresh" the list give me no results. No list of folders. What should I do? I'm thinking I could delete the dovecot files: dovecot.index, dovecot.index.cache, dovecot.index.log, dovecot-uidlist, subscriptions, and while I'm at it possibly dovecot-keywords. Then access the account(s) and Dovecot will rebuild them with the true/correct information. Am I heading anywhere near the right direction? TIA, Rod --

[Dovecot] Maildir structure question

Hello, About the INBOX location when using maildir, in the wiki, http://wiki.dovecot.org/MailboxFormat/Maildir, I can read: " Directory Structure ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX. The tmp directory is used during delivery, new messages arrive in new and read shall be moved to cur by the clients. " But in my Maildir, I see this: niko@petole:~$ ls -la Maildir/ total 144 drwxr-xr-x 35 niko niko 4096 2009-02-06 08:37 . drwxr-xr-x 25 niko niko 4096 2009-02-06 10:26 .. drwxr-xr-x 5 niko niko 4096 2009-02-06 09:16 .INBOX ...

[Dovecot] Best Imap Transfer Tool?
by Neil 08 Feb '09

08 Feb '09

So I'm looking to do a migration of my IMAP mailboxes, and I'm looking for the best tool to use. I used to use the uw-mailutil tool, a while ago, but that was a bit coarse of a tool. More recently I've used imapsync, but that was giving me some errors. I've sort of tracked those down; but I was wondering if anyone else had any other recommendations...? Thanks.

[Dovecot] Info regarding conversion of mbox to maildir
by Scott Silva 06 Feb '09

06 Feb '09

When I finally decide to convert to maildir, will I have to set up namespaces during the conversion, or will dovecot figure out where everything is by itself? Should I set up deliver to go to maildir/ globally, or per user? I have considered using the convert plugin, if there are not a lot of negatives. -- MailScanner is like deodorant...

[Dovecot] Public namespace permissions documentation/questions
by Thomas Hummel 06 Feb '09

06 Feb '09

Hello Timo, In my trials to setup a shared namespace with dovecot-1.1.8/LDAP passdb/userdb (prefetch)/Maildir, I found out that : 1) ACL are mandatory (at least if the acl plugin is triggered in dovecot.conf) Am I correct ? I'm still not sure if we can do without ACL at all (only with unix permissions and system_user userdb extra field). 2) the system_user userdb extra field is supposed to be ...the logname of the user the secondary groups of whom we want to check ! i.e. if user foobar belongs to secondary groups foogid, zgid, wgid and doveshared uid=xxx(foobar) gid=yyy(foogid) groups=zzz(zgid),www(wgid),vvv(doveshared) and we dovecot to take them into account, we have to make the usedb return the system_user extra field with the value foobar. Seems obvious now and said this way, but looking at the wiki : "system_user: If this is given, the user's groups are read from /etc/group (or wherever NSS is configured to taken them from)." I thought 'system_user' was a flag (a boolean) which, when triggered made dovecot look for the secondaries group of the user (user whose name is already known). a) am I correct ? b) why isn't system_user such a boolean ? Is there a case where we'd want system_user to be different than the user dovecot runs as at the moment the check takes place ? 3) same idea with acl_groups : since this extra_field holds a list of groups for the ACL plugin, why not rely on the native unix groups of the system the user belong to ? Thanks (and sorry for the 2 previous threads where I was blindly confused by the system_user thing). -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] dovecot-shared file
by Thomas Hummel 06 Feb '09

06 Feb '09

Hello Timo, About the dovecot-shared file, the wiki says : "Unless you're using a single UID for all the users, you'll need to have a dovecot-shared file in each shared maildir. The group and the file permissions for new files inside the maildir are taken from the dovecot-shared file." but says the following too : "With Maildir dovecot-shared file controls if the \Seen flags are shared or private. If you don't have the file, they're shared." The question is "does it make sense (or is it even possible) not to have the file ?". Why would one not have the file and how would it work then ? By relying on the set-gid bit and umask ? Finally, the wiki says : "If you do have the file, the \Seen flag state is stored only in the user's index files. By making each user have their own private index files, you can make the \Seen flag private for the users." So, my undersanding is that : 1) you have the file 1.a) if INDEX points to the same place, flags are shared but are lost if indexes are lost 1.b) if INDEX points to some user dependant place, flags are private but are lost if indexes are lost 2) you don't have the file flags are shared, whatever INDEX points to and, since they're stored in filename, survive indexes lost. but does shared-mailboxes even work if we don't have that file ? maybe only if the set-gid bit and umask does what the file would have done ? So maybe, if you want to share flags, 2) is safer dans if you want them private, 1.b) is the only choice ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Shared subscription, acl-list and uidvalidity(s)
by Thomas Hummel 06 Feb '09

06 Feb '09

Hello, I'm running dovecot-1.1.8/Maildir/ACL plugin. I sucessfully set up a Maildir shared between users of the unix group 'doveshared' via a public namespace, unix permissions and ACL files. The location of my public namespace is /path/to/public. I tried 2 sub-setups : First setup ---------- drwxrws--- 4 root doveshared 4096 Jan 30 13:39 public -rw-r----- 1 root doveshared 18 Jan 30 13:38 public/subscriptions I first connect (in Thunderbird) to dovecot with user 'hummel', then with user 'doveimap'. The following files are created in /path/to/public/ : -rw------- 1 doveimap doveshared 40 Jan 30 14:03 dovecot-acl-list -rw------- 1 hummel doveshared 8 Jan 30 14:03 dovecot-uidvalidity -rw------- 1 hummel doveshared 0 Jan 30 14:02 dovecot-uidvalidity.4982fa7a I've got my own idea about what they're used for, but can you explain what they are supposed to be ? I guess the uidvalidity files are UIDVALIDITY, not for the mailboxes the namespace holds (since my understanding is that the uidvalidities of mailboxes are stored in the first line of dovecot-uidlist files), but for the namespace itself (in case it is destroyed and then recreated for instance). Am I right ? Why 2 files ? Second setup ------------- I follow the 'Shared subscriptions' section of the wiki : drw-r-s--- 4 root doveshared 4096 Jan 30 14:19 public -rw-r----- 1 root doveshared 18 Jan 30 13:38 public/subscriptions As expected, dovecot (and it shows in the logs), has not sufficient permissions to create the files above (dovecot-acl-list, dovecot-uidvalidity, dovecot-uidvalidity.4982fa7a). What are the consequences ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] NFS - inotify vs kqueue
by Jack Stewart 06 Feb '09

06 Feb '09

Hi, I've seen some chatter on NFS boards about kqueue being more reliable than inotify when used in NFSv3 and NFSv2. The chatter is a bit old so I don't know if it is true anymore. Anyone have pro/con experience with dovecot on the inotify/kqueue question when using NFS storage? I realize that kqueue is probably a bit slower and causes some delay with IDLE. Also, it may not really make any difference which is why I ask the question. ---Jack

[Dovecot] Hi all,
by Jehan Pagès 06 Feb '09

06 Feb '09

Hi all, as I told earlier, I am installing an email server with postfix/dovecot/dspam (for now that's all, though some programs may come later). For now, what works good enough is that I receive mails and spams are tagged. Dovecot version 1.1.7-r1 compiled from the gentoo depository with debug. The path of a mail is 1/ to be passed to dspam by postfix as a virtual transport with this in master.cf: dspam unix - n n - - pipe flags=DRhu user=vmail argv=/usr/bin/dspam --client --deliver=innocent,spam --user ${recipient} and this in main.cf: virtual_transport = dspam 2/ Then in dspam.conf, I have: TrustedDeliveryAgent "/usr/libexec/dovecot/deliver -d %u" UntrustedDeliveryAgent "/usr/libexec/dovecot/deliver -d %u" QuarantineAgent "/usr/libexec/dovecot/deliver -d %u -m Junk" Now dspam is tagging a lot of my spams, with [SPAM] on the subject and in the header stuffs like this: X-DSPAM-Result: Spam X-DSPAM-Processed: Thu Feb 5 23:49:02 2009 X-DSPAM-Confidence: 0.5232 X-DSPAM-Probability: 0.9869 X-DSPAM-Signature: 498b6cde61901804284693 X-DSPAM-Factors: 27, Subject*watch, 0.99000, a+loved, 0.99000, Subject*for+all, 0.99000, ... ... But I wanted spam to go in my Junk folder (using maildir, this is the directory .maildir/.Junk for my configuration. Hence the above configuration of QuarantineAgent. But it doesn't work as my emails are still deliverd to INBOX. How could I check that dovecot deliver is taking into account the option "-m Junk"? Or maybe I don't use it well? (I tried also "-m .Junk" as it it the name of the directory but it is the same) Note also that I use maildir format, so maybe this option works only with mailbox? The doc says: -m <mailbox>: Destination mailbox (default is INBOX). In my dovecot.conf, I have: protocol lda { hostname = mydomain.tld log_path = /home/vmail/dovecot-deliver.log info_log_path = /home/vmail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master } And when a deliver occures, that's all I have in dovecot-deliver.log: deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: recipient(a)mydomain.tld deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: home=/home/vmail/mydomain.tld/recipient/ deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: uid=1004 deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: gid=1004 deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: maildir: data=/home/vmail/mydomain.tld/recipient/.maildir deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: maildir++: root=/home/vmail/mydomain.tld/recipient/.maildir, index=, control=, inbox= =/home/vmail/mydomain.tld/recipient/.maildir deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Warning: Growing pool 'Cache fields' with: 2048 deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: msgid=<000d01c987ed$879c82f0$6400a8c0@biancauj3>: saved mail to INBOX Is there a way to check the options set on parameters in the logs, so that I check that dspam runs indeed QuarantineAgent? Or would you have other solution/hints? Someone on the dspam ml told me that maildrop or sieve are more flexible. So I explain here that my "reason" was simply that I thought it would be better not to install another software/component to remain simple. Moreover with the "-m" option, dovecot-deliver seemed to do just what I needed (I don't need much more complicated). But maybe I am wrong or it is really better not to use dovecot-deliver. If so, just tell me. Thanks. Jehan

[Dovecot] ¿DC won't start? "leaked file fd 5:"
by mathemat＠gmx.net 06 Feb '09

06 Feb '09

Hi Gents, (apologizes, new here...) I didn't find any hint on G**gle nor in the Dovecot archieve (maybe due to the lack of a search function :), so: I installed Doovecot, but can't get it going. The logfile states: > mail.info dovecot: Dovecot v1.0.15 starting up > mail.err dovecot: auth(default): Panic: Leaked file fd 5: dev 0.10 inode 3 > mail.err dovecot: Auth process died too early - shutting down I tried many obscure things to recover, but had no luck so far. As long i am just guessing around (auth? dev 0.10?? maybe SSL config?), i have no clue what happens here :(. To make things more interesting: the installation lives on an embedded device (xscale, aka arm w/4MB RAM), where are no extended debug features available (like ltrace, ldd,...), and no newer packages (if exist) available. Tried so far: * uninstall (ipkg remove) * rm'd all files listed in the package description + /var/run/dc/* * reinstall (ipkg install) * changed the config file (in many ways... but what??) The init-script does mainly "/opt/sbin/dovecot", so i tried that command on the CLI(bash) to be sure no script mangles fd's around. "echo $?" gives "0" then, but no DC process is running- log messages as above. I have no clue what to do abt that- where's the point?? Can this hopefully be done whithout installing the complete gcc toolchain and compiling a newer version from source, but by just adapting the config? 8-| Any helpful hints appreciated!, acend -- -- Psssst!

[Dovecot] Dovecot performance on GFS clustered filesystem
by Allen Belletti 06 Feb '09

06 Feb '09

Hello All, We are using Dovecot 1.1.3 to serve IMAP on a pair of clustered Postfix servers which share a fiber array via the GFS clustered filesystem. This all works very well for the most part, with the exception that certain operations are so inefficient on GFS that they generate significant I/O load and hurt performance. We are using the Maildir format on disk. We're also using Dovecot's deliver from Postfix to handle local delivery. As best I can determine, the worst problems occur when certain users with very large Inboxes (~10k messages) receive new mail and their client looks up information about that message. GFS doesn't seem to efficiently handle the large directories that contain folders like this. As a result, lots of I/O ops are generated and performance suffers for everyone. I am beginning to wonder if it might be more efficient to revert to the old mbox format, with one file per folder (plus whatever indices are creates.) It seems that this ought to work better with GFS which is geared toward smaller numbers of larger files. Is anyone on the list currently doing that? Alternately, any thoughts regarding tuning or other options would be appreciated. Thanks, Allen -- Allen Belletti allen(a)isye.gatech.edu 404-894-6221 Phone Industrial and Systems Engineering 404-385-2988 Fax Georgia Institute of Technology

[Dovecot] The 'dbox' Format
by Alexander Beisig 05 Feb '09

05 Feb '09

I'd like to give the dbox format a try, but I could not find any information on how to enable it. There's information on how to set mail_location for the Maildir and mbox formats in the wiki and also in the commented configuration file, but how to set it for dbox is strangely missing. I took a guess with 'mail_location = dbox:~/dbox', but that didn't work, so it's probably not the right way. Also, the version of Dovecot that Debian installed was 1.0.15, which is kinda old. Should there any serious reasons why I should manually install a newer version if I'm going to use dbox? __________________________________________________________________ Deutschlands größte Online-Videothek schenkt Ihnen 12.000 Videos!* http://entertainment.web.de/de/entertainment/maxdome/index.html

[Dovecot] Deferred emails on alias emails
by Jehan Pagès 05 Feb '09

05 Feb '09

Hi, I am currently making a fresh install of email server. I am having some issue with dovecot-antispam (cf. other emails), and noticed that I was having issues on aliases, which apparently where not forwarded to the actual SMTP server after passing through dspam. Still don't figure why but temporarily disable the dspam filter, which anyway is not useful in the current state of this installation. Now the email to an alias are well forwarded to the real finale server. But I still have many emails which were deferred in the last days and I cannot have them decrease. # ls -l /var/spool/postfix/defer/* | wc -l 297 If I run "postqueue -f" to flush this all, I can see the number down, but fastly comes back to 297. Reading the logs, they are passed to dovecot, which was probably the issue before I disabled dspam. It was trying to deliver a message after filtering it, but in the case of aliases, of course, it cannot because the account is not local (so it does not find the account and defers the email forever)! So it should give it back to postfix so that this one contacts the aliased server (gmail.com in the example below). Feb 4 13:33:18 ks34186 postfix/lmtp[31100]: 82769869FA: to=< someemail(a)gmail.com>, orig to=<someemail(a)mydomain.tld>, relay=mail.mydomain.tld[/var/run/dspam/dspam.sock] conn use=28, delay=142296, delays=142277/19/0/0.41, dsn=4.3.0, status=deferred (host mail.mydomain.tld[/var/run/dspam/dspam.sock] said: 421 4.3.0 <someemail(a)gmail.com> Auto-Whitelisted (in reply to end of DATA command)) Feb 4 13:33:18 ks34186 dovecot: auth(default): master in: USER 1 someemail(a)gmail.com service=deliver Feb 4 13:33:18 ks34186 dovecot: auth(default): passwd(someemail(a)gmail.com): lookup Feb 4 13:33:18 ks34186 dovecot: auth(default): passwd(someemail(a)gmail.com): unknown user Feb 4 13:33:18 ks34186 dovecot: auth-worker(default): sql( someemail(a)gmail.com) SELECT maildir as home, 1004 as uid, 1004 as gid FROM mailbox WHERE username = 'someemail(a)gmail.com' AND active = '1' Feb 4 13:33:18 ks34186 dovecot: auth-worker(default): sql( someemail(a)gmail.com) Unknown user Feb 4 13:33:18 ks34186 dovecot: auth(default): master out: NOTFOUND 1 So is there a way please to flush this whole spool so that it now uses the new method (which is stop using dspam until I figure how to use it) and so that I can forward these emails to their recipient? Thanks. Jehan P.S.: this is maybe more a postfix issue than a dovecot issue though... but you probably all know well postfix as well.

[Dovecot] dirsize quota in sql pass db?

Is there a way to return a per user dirsize quota from a passdb sql lookup? If so, what is the syntax? maybe "select quota as userdb_quota"? ..and in mysql table, quota column would be: "quota=dirsize:storage=10240" ?

I'm sure I'm missing something obvious :-( Dovecot version 1.1.6, pam authentication via ldap (openldap). basicly, we use: passdb pam userdb passwd which work fine, except for Outlook/OL Express users that are asked for their password whenever they "send/receive"... We've had also "passdb shadow" that somehow "fixed" this but allowed also users with expired passwords to login :-( re-added for now, untill the correct configuration is achived).

[Dovecot] Script: Moving Maildirs between servers

Hi, I just migrated from dovecot 1.0.rc29 to 1.1.7, from Sparc platform to Intel, it went very well. In the process I merged folders and excluded folders from being copied.

[Dovecot] pop3_lock_session question
by Mark Costlow 04 Feb '09

04 Feb '09

Hello, I'm preparing to convert from qpopper + UW-IMAP to dovecot. So far testing has gone very well. One problem we haven't figured out is that long-running POP sessions keep the mailbox locked, so that the MDA times out while trying to deliver. We're using "maildrop" as our MDA if that matters. We don't see this issue for dovecot IMAP sessions. During long-running IMAP sessions, incoming messages are deilvered tot he user's INBOX without delay. But with POP, the MDA times out and the messages go back to sendmail's queue for later delivery. We though this setting would address the issue: # Keep the mailbox locked for the entire POP3 session. pop3_lock_session = no But it doesn't seem to. Any ideas? Here is our "dovecot -n": ---------------------------------------------------------------------- # 1.1.8: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.1-RELEASE-p2 i386 base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/mail/certs/mail.swcp.com.pem ssl_key_file: /etc/mail/certs/mail.swcp.com.pem ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 100 mail_privileged_group: mail mail_location: mbox:~/:INBOX=/var/mail/%u:INDEX=/var/dovecot/%u mail_full_filesystem_access: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock mbox_lock_timeout: 120 dbox_rotate_days: 0 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 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_reuse_xuidl(default): no pop3_reuse_xuidl(imap): no pop3_reuse_xuidl(pop3): yes pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login username_format: %Lu winbind_helper_path: /usr/local/bin/ntlm_auth verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: session=yes dovecot userdb: driver: passwd args: blocking=yes socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 ---------------------------------------------------------------------- Thank, Mark -- Mark Costlow | Southwest Cyberport | Fax: +1-505-232-7975 cheeks(a)swcp.com | Web: www.swcp.com | Voice: +1-505-232-7992 abq-strange.com -- Interesting photos taken in Albuquerque, NM Last post: Cruising San Mateo I - 2009-01-04 15:20:30

[Dovecot] Starting using LaunchDaemons

I've figured this one out... Just wanted to get it into the dovecot mailing list archive so that somebody in the future might find it if they need it. Running Dovecot on Mac OS X 10.4.11 and using LaunchDaemon to start. Following a system crash, dovecot failed to restart with this in the system log... Feb 4 10:04:29 G520X2 launchd: org.dovecot: exited with exit code: 89 Feb 4 10:04:29 G520X2 launchd: org.dovecot: respawning too quickly! throttling Feb 4 10:04:29 G520X2 launchd: org.dovecot: 7 more failures without living at least 60 seconds will cause job removal Feb 4 10:04:29 G520X2 launchd: org.dovecot: will restart in 10 seconds Feb 4 10:04:39 G520X2 launchd: org.dovecot: exited with exit code: 89 Feb 4 10:04:39 G520X2 launchd: org.dovecot: respawning too quickly! throttling Feb 4 10:04:39 G520X2 launchd: org.dovecot: 6 more failures without living at least 60 seconds will cause job removal Feb 4 10:04:39 G520X2 launchd: org.dovecot: will restart in 10 seconds Feb 4 10:04:49 G520X2 launchd: org.dovecot: exited with exit code: 89 Feb 4 10:04:49 G520X2 launchd: org.dovecot: respawning too quickly! throttling Feb 4 10:04:49 G520X2 launchd: org.dovecot: 5 more failures without living at least 60 seconds will cause job removal Feb 4 10:04:49 G520X2 launchd: org.dovecot: will restart in 10 seconds The problem turned out to be an old master.pid file (/usr/local/var/ run/dovecot/master.pid) that was left over from the crash. Deleting the file allowed dovecot to restart. Actually, dovecot told me what the problem was when I attempted to start it from the command line as opposed to starting it with the LaunchDaemon...

[Dovecot] auth_debug_passwords
by Josh Gentry 04 Feb '09

04 Feb '09

Hi. I'm new to Dovecot and about to start using it in production. In the config file, I set the option, auth_debug_passwords, to yes. I do not see any failed passwords logged, however.

I was using the RoundCube web client on my server and had no such message. It was just telling me that it could not move the message. I configured a Thunderbird then and it displayed indeed this message 'Failed to call dspam'. So I made your trick, I compiled myself the dovecot-antispam library and now I can move messages... But are you sure that it is the right method and that the dspam training is indeed called? Because if I read well this piece of code, it looks like it was checking if the dspam training was successful. We commented out this check, so now maybe it fails and we copy the messages anyway to Junk/ even though no training really occurred. And when I check the logs or the dspam_stats, I don't see any change, even though I guess this retraining should be seen as a change in the stats, no? > > Antispam plugin is easy to understand: when you configure antispam_spam > = SPAM it will set SPAM folder as his special folder to observe.

[Dovecot] Latest CentOS rpms.

Along with my post about authentication I was wondering if anyone was building RPMs for the later versions of dovecot (and postfix) than I can find in the usual and not-so-usual yum repos? I already pull from rpmforge but would prefer something later than 1.0.7 Say the 1.1 series. Thanks, Rod --

[Dovecot] Dovecot on Mac - Entourage cannot fetch emails
by Bijo 03 Feb '09

03 Feb '09

Hi, Dovecot 1.1.3 is running on Mac OS X 10.5 latest version, with Maildir (LAYOUT=fs). I have following issues when Entourage 2008 connects it, over imap/imaps. Entourage does not cache the mails. After every restart the folder contents are fetched fresh. I have enabled the Entourage option to get entire messages. Entourage caches the gmail IMAP folders fine. Also Outlook 2007 does not have this problem while connecting to the same IMAP server. I have some big folders with a few thousands of emails. Entourage fails with Error: 4362 (Mail could not be retrieved this time) while fetching mails from these folders. Restarting and rebuilding the Entourage database did not fix this issue. Any tips to resolve these issues or to debug what is going on would be greatly appreciated. Thanks, Bijoy -- View this message in context: http://www.nabble.com/Dovecot-on-Mac---Entourage-cannot-fetch-emails-tp2175… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 1.1.10 and chroot
by Michal Soltys 03 Feb '09

03 Feb '09

As it's been a while since I upgraded (1.1rc10, jump to 1.1.10), this might be present in earlier versions as well. Anyway, if one enables mail_chroot in global config file, dovecot will try to access /tmp there. Per-user overrides behave correctly. For example, with: mail_chroot=/home/vmail dovecot will abort with: Fatal: chdir(/home/vmail/tmp) failed with uid 65534: No such file or directory Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot.conf

[Dovecot] Dovecot-antispam does not work
by Jehan Pagès 03 Feb '09

03 Feb '09

Hi, I have installed dovecot-antispam and configured it this way (as in the doc) with the dspam exe: protocol imap { mail_plugins = antispam mail_plugin_dir = /usr/lib64/dovecot/imap } plugin { # For dovecot-antispam: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items antispam_spam = SPAM;Junk #antispam_unsure = unsure antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --deliver=;--user;%u antispam_mail_tmpdir = /tmp } But it does not work and really I cannot figure it out for two days, because I can find no log wherever, where it writes it does (or try to do) something, nor in the dovecot logs, nor in the dspam logs. But I know something is happening because when I try to move a spam from my inbox to the Junk folder, it fails with an error telling it could not move the email. At the opposite, when I deactivate the antispam plugin, I can move normally the emails. So what could I do to fix my issue or at least diagnose it (where would I find logs of what is happening?)? Thanks. Jehan

[Dovecot] Mail undeliverable error
by jan gestre 03 Feb '09

03 Feb '09

Hi Guys, I've already posted this to the postfix mailing list and they made sure the error as the title suggest was generated by dovecot and not the other way around. I have an almost perfectly working multi domain mail server running dovecot+postfix+mysql+postfixadmin behind pfsense, when we transferred office, issues arose, suddenly users using email clients like thunderbird/outlook suddenly can't send mail when outside the office and instead gets an smtp denied or worst a mail undeliverable error. The mail undeliverable error was that the postmaster user is unknown yet I've created the alias using postfixadmin. I've made repeated test and sent mail directly to the postmaster and the email was received by the intended user, I'm stumped and have no idea to fix this. Hope you can help me, TIA.

[Dovecot] sieve 0.1.2 problem with address and :regex

[Dovecot] cram-md5 problem re-post
by Richard Stockton 03 Feb '09

03 Feb '09

I apparently did not post enough information the first time, so I am re-posting the original email with the requested configs. I just updated to dovecot 1.1.10 from 1.1.2 and now anyone using cram-md5 can't get authenticated. I am using mysql for passwords (in plain text) and home directories. Per some googling I tried to set (in /usr/local/etc/dovecot.conf): # SQL database userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } but that didn't help. And in any case people NOT using cram-md5 can authenticate just fine, both before and after I made that change. This worked "out of the box" under 1.1.2, but is broken now. Here's an example I pulled from the logs. dovecot: Jan 29 16:35:03 Info: auth-worker(default): sql(jennshinjo,xx.xx.xx.xx): SELECT home, uid, gid FROM users WHERE username = 'jennshinjo' AND domain = '' dovecot: Jan 29 16:35:03 Info: auth(default): prefetch(jennshinjo,xx.xx.xx.xx): success dovecot: Jan 29 16:35:03 Info: auth(default): master out: USER 1490 jennshinjo home=j/e/jennshinjo/Maildir/ uid=5000 gid=5000 home=j/e/jennshinjo/Maildir/ uid=5000 gid=5000 dovecot: Jan 29 16:35:03 Info: pop3-login: Internal login failure (auth failed, 1 attempts): user=<jennshinjo>, method=CRAM-MD5, rip=xx.xx.xx.xx, lip=10.255.0.11 Here is the "dovecot-sql.conf": :> more /usr/local/etc/dovecot-sql.conf driver = mysql connect = host=10.211.1.3 dbname=mail user=postfix password=p0stf1x9 default_pass_scheme = PLAIN password_query = SELECT password, home as userdb_home, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox where userid = '%n' Here are the results of "dovecot -n": :> dovecot -n # 1.1.10: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-128.el5 i686 Red Hat Enterprise Linux Server release 5.3 (Tikanga) ext3 base_dir: /var/run/dovecot/ log_path: /var/log/pop.log info_log_path: /var/log/dovecot-info.log protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_cert_file: /etc/ssl/certs/server.crt ssl_key_file: /etc/ssl/private/server.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no verbose_ssl: yes login_dir: /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 login_greeting: Dovecot on mail-pop01.xxxxx.com ready. verbose_proctitle: yes mail_location: maildir:/mail/%h:INDEX=MEMORY mmap_disable: 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_plugins(default): mail_log mail_plugins(imap): mail_log mail_plugins(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 mail_log_max_lines_per_sec: 0 auth default: mechanisms: plain cram-md5 debug_passwords: yes process_size: 1024 passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: prefetch Any ideas appreciated.

[Dovecot] About behavior when I used mysql for dict quota backend
by hideck 03 Feb '09

03 Feb '09

Hi List, I of present dovecot 1.1.10 use it, and test dict quota backend and mysql. However, I am troubled so that it is IMAP4, and behavior when mysql fell is different from POP3. I become the error in Copy of Mail in IMAP4, but do not become the error in DELE of the POP3. Therefore I think that contradiction happens in database and real storage when mysql fell. I want an error to do it at the time of the DELE command of the POP3 if possible, but how will be it? Thank you for keeping company at my clumsy English. ---------------------------------------------------- # dovecot -n --------------------------- # 1.1.10: /etc/dovecot.conf # OS: Linux 2.6.18-92.1.22.el5xen i686 CentOS release 5.2 (Final) protocols: imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_max_userip_connections(default): 100 mail_max_userip_connections(imap): 100 mail_max_userip_connections(pop3): 10 last_valid_uid: 65000 mail_location: maildir:~/Maildir mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/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/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: cache_size: 10 cache_ttl: 300 passdb: driver: pam userdb: driver: passwd socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: dict:user::proxy::quotadict quota_rule: *:storage=1536M quota_rule2: Trash:ignore dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf --------------------------- mysql status --------------------------- mysql> SELECT username,current,path FROM quota WHERE username="test"; +----------+---------+----------------+ | username | current | path | +----------+---------+----------------+ | test | 1 | quota/messages | | test | 1460 | quota/storage | +----------+---------+----------------+ 2 rows in set (0.00 sec) --------------------------- # /etc/init.d/mysqld stop Connectting my server (IMAP4) syslog --------------------------- Feb 3 08:38:40 hideck dovecot: imap-login: Login: user=<test>, method=PLAIN, rip=192.168.31.72, lip=192.168.0.1 Feb 3 08:38:46 hideck dovecot: dict: mysql: Connect failed to localhost (dovecot): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) - waiting for 75 seconds before retry Feb 3 08:38:46 hideck dovecot: dict: dict sql lookup failed: Not connected to database Feb 3 08:38:46 hideck dovecot: IMAP(test): Internal quota calculation error Feb 3 08:38:51 hideck dovecot: IMAP(test): Disconnected: Logged out bytes=357/1211 --------------------------- Connect Clients Log(IMAP4) --------------------------- * OK Dovecot ready. 0114 CAPABILITY * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN 0114 OK Capability completed. 0115 LOGIN ******** ******** 0115 OK Logged in. 0116 NAMESPACE * NAMESPACE (("" "."))

[Dovecot] Using dovecot sasl for authenticating in openldap
by Nathan Huesken 02 Feb '09

02 Feb '09

Hi, I am using dovecot imaps and exim, both authenticating using dovecot-sasl. To keep passwords in one place I would like to authenticate openldap users over dovecot-sasl. So looking at this page: http://www.openldap.org/doc/admin24/security.html I figure it could be done using Pass-Through authentication. For this, I need to create /usr/lib/sasl2/slapd.conf And adding a few config paremeters. This is a example mech_list: plain pwcheck_method: saslauthd saslauthd_path: /var/run/sasl2/mux I understand the mech_list parameter, but I have no Idea what to put in for the rest. Any help? Thanks! Nathan

[Dovecot] Phone cannot receive mail suddenly

Starting at midnight Feb 1 my phone can no longer fetch mail from Dovecot. It endlessly connects and reconnects as you can see in the log below. I have restarted dovecot, the phone, deleted /home/robinmail/mail, all to no avail. I have turned on debug output but it does not tell me anymore. I can connect and see the folder using the KMail imap client. Any idea how I can proceed with this? The phone is 192.168.1.57 (LAN) or 202.91.19.194 (GPRS) and Dovecot and KMail are on 192.168.1.2.

[Dovecot] Bug in Deliver v1.2

[Dovecot] Config rewrite for v1.3
by Timo Sirainen 02 Feb '09

02 Feb '09

Still broken, but I committed the current changes to http://hg.dovecot.org/dovecot-config-rewrite/ The idea is something like: - src/config/ contains a doveconf binary which can be used to dump the current configuration. It's the only binary that reads dovecot.conf directly. Currently the code is kind of ugly because I wanted it to be able to parse the existing v1.2 dovecot.conf which required some kludging around. Perhaps in v2.0 the dovecot.conf could have larger changes and these kludges could be removed. - master currently executes doveconf 3 times: for default settings, for imap settings, for pop3 settings. The result is saved into an array of KEY=value pairs in an array. Eventually they're still sent to child processes via environment. This sending via environment is again mainly for backwards compatibility with post-login scripts. Although they are useful there, so I'm not sure if it should be kept that way. Although post-login scripting doesn't really work anymore with Apple's multiple-connections-per-mail-process code, so perhaps that needs some rethinking in any case.. - deliver also currently forks and executes doveconf. I hate this. But I don't like the alternative of having a libconfig that deliver could use to read the configuration inside the binary as is done now, because then it's not as easy anymore to update the doveconf binary (or replace it entirely). But I'm thinking about making doveconf a long running process and deliver could ask configuration from it via UNIX socket if it's running and fallback to forking doveconf. The last possibility would be not to fork, but instead just have doveconf exec() deliver, so either something like "doveconf -e deliver -deliver-params" or if calling deliver directly it could exec() doveconf which would then exec() deliver back. Hmm. Perhaps this is actually better than forking? - %variable expansion is somewhat broken with imap/pop3, but works with deliver. The annoying thing about this is that %vars from doveconf should be expanded, but if userdb returns anything containing %vars they shouldn't be (because e.g. home directory could contain %). So either master should expand everything internally or it should somehow tell child processes about what to expand and what not. It can't really expand everything because it doesn't know all the settings that should be expanded. So that only leaves the possibility of telling child process what to expand. One possibility is to prefix each environment with e.g. 0 or 1 specifying if it should be expanded. This would break all existing postlogin scripts and in general would make it kind of ugly. Another possibility would be to have an environment that lists the settings that shouldn't be expanded. Perhaps that would work better, although if postlogin script changes/adds environments they'd also potentially have to modify that environment too. - Plugins will probably have to keep using something similar to getenv() to get their settings. It would be possible to have them use the nice new pre-filled settings structures, but that would require configuration changes. For example instead of quota=.. quota2=.. you'd have two quota {} blocks. Probably better to leave that change to v2.0. - I'm not entirely sure where all the setting verifications should go. Having them done by master when starting up is nice because it can give error messages immediately and write them to screen, instead of having to look them up from the log. Or when reloading configuration it can cancel it if the new configuration isn't ok. Maybe doveconf could do the checks. Maybe the verifications could go to all the different *settings.c files where they logically belong to, and then the build scripts would copy those functions to doveconf code where it could check all of them when the config is being read. The only annoying thing is that this then required doveconf to be run as root so that it can do all the access() etc. checks. But maybe that's not too bad.

[Dovecot] mbox to maildir batch conversion
by Mike Hobbs 02 Feb '09

02 Feb '09

Hello, I'm upgrading my mail server from UW to Dovecot and I'd like to convert from mbox to maildir. I've successfully convert myself and a few other users with the mb2md script. All is well. My question is, I have somewhere around 500 users and about 122gb of mail folders to convert (this does not include the inbox at /var/mail). mb2md needs to be run as each user to convert. Are there any programs or scripts out there that will allow me to convert everyone at the same time? I know there is a Dovecot plugin to convert mail, but we didn't want to use this option. I'm sure someone on this list was in the same situation as me, how did you handle a massive conversion? Any help or suggestions is much appreciated!

[Dovecot] managesieve/README sieve_storage doc confusion
by Steffen Kaiser 30 Jan '09

30 Jan '09

However, this is provided only for backwards compatibility and you should always use the sieve_storage setting in stead. Additionally, the ManageSieve service uses the following settings from the plugin section of the config file. These settings are the ones used by the Sieve plugin. sieve_dir = This specifies the path to the directory where the uploaded scripts are stored. Scripts are stored as separate files with extension .sieve, all other files are ignored when scripts are listed by a ManageSieve client. If this setting remains unspecified, the mail_location setting is used as explained above. " Because sieve_storage is not mentioned anywhere else in the document and because of this discussion: http://dovecot.markmail.org/message/kzjpwdhyqhdn53zd , I suspect that sieve_dir is the older naming of it.

Or was it you? Anyway, dovecot-auth doesn't know how many users are logged in so if the problem really is 21 *concurrent users* instead of n logins/ second, I find it highly unlikely that the problem is with authentication.

[Dovecot] cram-md5 problem
by Richard Stockton 30 Jan '09

30 Jan '09

I just updated to dovecot 1.1.10 from 1.1.2 and now anyone using cram-md5 can't get authenticated. I am using mysql for passwords (in plain text) and home directories. Per some googling I tried to set (in /usr/local/etc/dovecot.conf): # SQL database userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } but that didn't help. And in any case people NOT using cram-md5 can authenticate just fine, both before and after I made that change. This worked "out of the box" under 1.1.2, but is broken now. Any ideas appreciated. Thanks. - Richard

[Dovecot] Killing Dovect, an unpleasant surprise
by Stewart Dean 30 Jan '09

30 Jan '09

When it came time to upgrade DC or replace the certificate, I would find the root instance of dovecot and do a kill -7 of it. Within 20-30 seconds, all the hundreds of DC related processes would go away, I would swap the executable or certificate/key and restart DC. Very clean and quick. Surprise. After switching from 1.0.15 to 1.1.8 and doing the kill, I found that all the imap-login instances had been inherited by the root (1) process and did not go away. Yikes! An Unpleasant Surprise. So instead of being down for a minute, I was out for a much more noticeable 5-7 minutes, while I QUICK did an awk of the ps list to give me the pids and then xarg killed them. My boss asked me if this was a pink slip notice. :( Is this The Way Things Will Be? Is there a new way to kill everything DC related quickly and cleanly? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035 "Resolve then, that on this very ground, with small flags waving and tinny blasts on tiny trumpets, we shall meet the enemy, and not only may he be ours, he may be us." === From the introduction to the original Pogo Papers

[Dovecot] deliver and qmail
by Tim Traver 29 Jan '09

29 Jan '09

Hi all, ok, after looking at all of the posts that I've found, and trying numerous settings, I am a little stumped as to how to set up the deliver program with qmail to get everything correct. Ultimately, I really don't want to do a lookup of the home dir if I don't have to. I'd rather specify the stuff in the .qmail-user file for that particular user to avoid the extra step. In looking in the wiki, it says for users without a lookup to use HOME=/path/to/user/homedir deliver -f $FROM_ENVELOPE but I can't do that in the .qmail file, which would normally look something like this : |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -f ${SENDER:-<>} I would rather not do the master authentication socket as described for obvious reasons. is there a format in the .qmail file that I can use with deliver to achieve what I want??? Thanks, Tim.

[Dovecot] Confused about permissions needed for shared mailbox
by Thomas Hummel 28 Jan '09

28 Jan '09

Hello, let me re-state, hopefully in clearer terms, what I tried to described in a previous thread : With dovecot-1.1.8/Maildir/LDAP pass/userdb (prefetch), I'm trying to set up a Maildir ".box" shared in rw between 2 users in a "Public" namespace. I can't get it to work unless I chmod 777 everything, which obiously is not what I want. 1) am I correct thinking that the system_user userdb extra_field and unix permissions should be enough to achieve that and that ACLs is only if I want to fine tunes mailbox permissions ? 2) let's say that my public namespace prefix is Public/, that the .box/ maildir is in /path/to/public/.box and my 2 users belong to the doveshared unix group. I thought it would be enough to have drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public/.box -rwxrws--- 1 root doveshared 0 Jan 26 18:25 public/.box/dovecot-shared provided that my prefetch userdb returns system_user, as I think the following says in dovecot-ldap.conf : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and providedt that in LDAP shadowMax: 80 (whatever value). But this doesn't seem to work. By the way : Am I supposed to have a dovecot-shared file in public as well (that is not only in public/.box) ? 3) let's say I try ACLs with the same setup (anyone <all permissions> for starters) would pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user.title=userdb_acl_groups and title: group1,doveshared be a correct setup ? Do I need an dovecot-acl file only in .box or in public too ? My understanding is that my setup doesn't work because for some reason, dovecot doesn't see my users secondary groups or doesnt take them into account... Any thoughts which might help ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

The Maildir layout goes like this : /courriel/boites/foobar : Maildir of user foobar (nfs) /courriel/meta/foobar : control files of user foobar (nfs) /var/dovecot/indexes : indexes (locally stored) I created : /courriel/boites/doveshared/.box/ : the Maildir I want to share /courriel/boites/foobar/.box -> /courriel/boites/doveshared/.box (symlink) /courriel/boites/foobaz/.box -> /courriel/boites/doveshared/.box (symlink) the unix and LDAP group doveshared, so /etc/group holds : doveshared:*:<gid>:foobar,foobaz the permissions on the real Maildir are ok for that group : drwxrwx--- 3 root doveshared 4096 Jan 26 18:58 /courriel/boites/doveshared drwxrwx--- 5 root doveshared 4096 Jan 26 18:58 .box (in /courriel/boites) I made the userdb (prefetch) return the system_user extra_field (for now, I'm using an used LDAP attribute - I will create a new attribute in my schema later) : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and it seems to be actually returned : Jan 27 09:34:10 munster3 dovecot: auth(default): ldap(foobar,157.99.64.42): result: uid(user)=foobar uidNumber(userdb_uid)=xxx gidNumber(userdb_gid)=xxx homeDirectory(userdb_home)=/home1/xxx/foobar userPassword(password)=<hidden> shadowMax(userdb_system_user)=380 But I can't subscribe to the mailbox : stat(/courriel/boites/doveshared/.box/tmp) failed: Permission denied (euid=xxx egid=<primary gid>) as a matter of fact, the egid seems to be the primary gid. What am I missing ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] (imap) killed with signal 9 on Linux/OpenVZ VPS
by Adam Flott 28 Jan '09

28 Jan '09

I'm trying to get dovecot running on my VPS and the main imap process is receiving a SIGKILL from what I presume to be the Linux Kernel and/or OpenVZ. This happens after I login and my client(s) just sit their idling. The mailbox is empty. I'm not running out of memory. stracing the process doesn't show anything interesting... ... gettimeofday({1233024777, 844804}, {420, 0}) = 0 gettimeofday({1233024777, 844912}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 3, 10000) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ This is on a CentOS 5.2 VPS. I haven't changed much other than installing a few packages. I've also had this exact same problem on Debian 4.0 VPS (OpenVZ) under the same machine. Turning off SSL and logging in plain old IMAP didn't change anything. Under the Debian installation I tried the latest version of dovecot (1.1.8 or so), different I/O loop methods, turning them off, on, etc. The only other reference via Google I can find to this sort of problem is: http://www.dovecot.org/list/dovecot/2007-December/027440.html But that was with the login process, whereas mine is with the imap daemon. Any help is greatly appreciated.

[Dovecot] Old Thunderbird problem - need a fix
by Marc Perkel 28 Jan '09

28 Jan '09

I've been having a Dovecot/Thunderbird problem for about a year now and I need a fix. When I restart dovecot everything is fine but as the day progresses thing start deteriorating. When I empty my trash folder it doesn't empty. I get an indication that email has arrived in my inbox by the unread message count but can't access it. Messages arrive by appear to be empty. Folders that should be empty still have message counts showing. With all of the above problems - restarting dovecot make them all go away. I am doing something unusual in that I use Exim to directly deliver (maildir) to the inbox and other folders. And I have processes that take email out of certain folders (spam learning). Whatever the problem is I think that when I restart Dovecot I'm forcing Thunderbird to reconnect. Perhaps the solution is to somehow force Thunderbird to have to reconnect every time rather than have a persistent connection? Looking for suggestions. Thanks in advance.

[Dovecot] Store sent email
by pierre.casenove＠almerys.com 28 Jan '09

28 Jan '09

Hello all, I've set up a webmail solution based on RedHat EL 5, sendmail, spamassassin, clamAV and dovecot by following this tutorial: http://www.redhat.com/magazine/025nov06/features/email/index.html I have configured everything without any problem, I can send and receive emails, using Maildir store format. Now, what I don't know how to set up: I would like to store the emails sent by the users in a dedicated store (Like Sent Emails in many webmails).... and I've got no idea on how to do this! By googling a little, I found this thread ( http://www.dovecot.org/list/dovecot/2007-April/021447.html) where a plugin is mentionned. Has it been developped or is there another solution? I'm using dovecot 1.0.7, shipped with RHEL 5 distribution. I am really discovering all the products around the email so I'm a bit confused. Thanks a lot for your answer, Pierre

[Dovecot] dotlock timestamp trouble

Hi there, I'm getting a lot of this message in production log: Created dotlock file's timestamp is different than current time (1232468644 vs 1232468524): /path/to/dovecot.index.log The IT guy swears the clocks are sincronized.

[Dovecot] No Spaces in Directory names
by Matt Rude 27 Jan '09

27 Jan '09

How can I make it so my users can not create folders with spaces in them? Or allow them to create such folders but rewrite them on the hardrive with a "_" or some other symbol. I have looked threw the wiki but couldn't find anything about folder name restrictions or folder name rewriting (rewrite the space to a "_"). Im having problems with some of the expire and compress scripts when it hits these types of folders. Is dovecot able to restrict or rewrite the names of imap folders? dovecot -n # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.27.9-159.fc10.i686 i686 Fedora release 10 (Cambridge) ext3 listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/postfix/SSL/mail.mattrude.com.cert ssl_key_file: /etc/postfix/SSL/mail.mattrude.com.key login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: postfix mail_location: maildir:/var/spool/virtualmailboxes/%d/%u/imap/:INBOX=/var/spool/virtualmailboxes/%d/%u/ mail_plugins: quota imap_quota zlib auth default: mechanisms: plain login cram-md5 cache_size: 128 cache_ttl: 600 master_user_separator: * passdb: driver: sql args: /etc/dovecot-mysql.conf passdb: driver: sql args: /etc/dovecot-sql-master.conf pass: yes master: yes userdb: driver: sql args: /etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: virtualmail group: virtualmail plugin: sieve: /var/spool/virtualmailboxes/%d/%u/dovecot.sieve sieve_storage: = /var/spool/virtualmailboxes/%d/%u/ quota: maildir quota_rule: *:storage=10M quota_rule2: Trash:storage=20% Thanks -Matt

[Dovecot] Dovecot discards mail over quota
by Gary V 27 Jan '09

27 Jan '09

I'm new to Dovecot, using 1.1.8 and I just wanted to verify that what I am observing is the intended behavior. I'm using Maildir++ quota. When a message is delivered to a mailbox that cannot accept the message because it would place them over the quota limit, deliver states to the MTA that the messsage was delivered successfully (example using postfix): Jan 17 12:05:31 msa postfix/pipe[13983]: 088C5B9D47: to=<test(a)example.com>, relay=dovecot, delay=0.72, delays=0.34/0.02/0/0.36, dsn=2.0.0, status=sent (delivered via dovecot service) But in actuality the mail is discarded (dropped). Then a bounce is created stating the mail was rejected: Your message to <test(a)example.com> was automatically rejected: Quota exceeded (mailbox for user is full). Question: is it possible (without changing code) to alter this to where deliver would instead tempfail or something. Somehow it seems wrong to me to tell the MTA that everything is good, and then silently discard messages - regardless of the fact dovecot creates a bounce. This is not necessarily ideal either, but I _am_ wondering if this is configurable or not. deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: save failed to INBOX: Quota exceeded (mailbox for user is full) deliver(test(a)example.com): 2009-01-17 12:05:31 Info: sieve runtime error: Keep: Generic Error deliver(test(a)example.com): 2009-01-17 12:05:31 Error: sieve_execute_bytecode(/var/sieve/global.sievec) failed deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: rejected: Quota exceeded (mailbox for user is full) deliver(garyv(a)example.com): 2009-01-17 12:05:31 Info: msgid=<dovecot-1232219131-401523-0@msa>: saved mail to INBOX -- Gary V

[Dovecot] behavior of dovecot with Openldap
by Masaharu Kawada 27 Jan '09

27 Jan '09

Dear team, I'm sorry if this is a stupid question, but I'd like to know the behavior of dovecot in a particular stuation. My questions are as follows. In /etc/dovecot-ldap.conf, 'hosts=' field is the one which can be used to specify availabled ldap server to access from the clients to authorize. And also sevral ldap servers can be specified in 'hosts =' field as shown like below. hosts = ldap-server1.example.com ldap-server2.example.com ※both server have the same configuration and available to replication ldap-server1(master) to ldap-server2(slave). If this is right, how does dovecot know which ldap server is currently used? and if the master dies, how does dovecot know and switch to slave one? In addition, which one is the exact behavior of dovecot in case master server dies? 1. only swithcing to the slave server 2. switching to the slave server, and once the master server is reactive then switch back to the master server automatically OS：RHEL4 U3 kernel 2.6.9-34.ELsmp openldap-2.2.13-12.el4 Thanks in advance, Masaharu Kawada ------------------- Masaharu Kawada Associate Global Support Engineer Red Hat K K Ebisu Neonato 8F 1-18 Ebisu 4-chome, Shibuya-ku Tokyo 150-0013, Japan Direct: +81-3-5798-8482

[Dovecot] FOLDER INTERNAL DATA (uw pine header)
by Charles Gregory 26 Jan '09

26 Jan '09

Hello! I run Dovecot on CentOS 4 (dovecot-1.1.4-0_81.el4), and I *also* run the "Alpine" mail system that comes with that OS. Alpine still writes out the 'FOLDER INTERNAL DATA' pseudo-message at the beginning of each user's mbox, but dovecot does not. I make use of that record as a simle/quick way to verify when a user actually last read their e-mail (for administrative purposes, identifying stale/unused accounts), so is there any way to configure/command dovecot to write (or update) these hidden messages? (Note: I tried looking in the archives, but most references seemed to be about this message being a 'side effect' of transferring *from* UW IMAP, and how to get 'rid' of it. Not what I need. :) Apologies if this was covered before in a different thread.) - Charles

[Dovecot] uint_cmp bug

In reviewing the differences between 1.1.8 and 1.1.9 I saw a probable bug in the new function uint_cmp() in src/lib-storage/index/maildir/ maildir-sync-index.c: if (*i1 < *i2) return -1; else if (*i1 > *i2) return -1; else return 0; The second case should return 1 not -1.

[Dovecot] Released ManageSieve v0.10.5 for Dovecot v1.1.9
by Stephan Bosch 26 Jan '09

26 Jan '09

Hello Dovecot users, Because there was a crash bug in the ManageSieve v0.10.4 login daemon, I made a new release of the ManageSieve service for Dovecot v1.1. This release includes two other small fixes as well. Changelog v0.10.5: - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed handling of ~/ in use of mail-data for script location The following files are released: ManageSieve package: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] userdb didn't return a home directory with v1.1.7
by Ivars Strazdiņš 26 Jan '09

26 Jan '09

Hi all, I am running Dovecot v1.1.7 in a relatively quiet and calm environment.

Hello I noticed a problem after upgrading to 1.1.8 Users that access to their mailboxes using webmail squirrelmail and HTTPS using HTTP seems to work correctly but it not safe enough ... There is an error message saying the imap server send a BYE command ... I downgraded our Dovecot server to 1.1.7 then it works again ...

[Dovecot] Shared Mailboxes (symlink) and kmail: known issues?
by Wilhelm Meier 26 Jan '09

26 Jan '09

Hi, are there any known issues with symlinked-shared-mailboxes and kmail? I use virtual users (LDAP), so there are no unix-permissions related problems here: all mailboxes are owned by the local user vmail. Each user maildir has some symlinks to shared mailboxes. This works fine if I use squirrelmail as a MUA. kmail instead seems to have some problems: if I save a mail into the shared-folder, the other users are seeing this new mail almost immediately. But if I delete(!) a mail from the shared-folder, the list of the other kmails remains untouch. Refreshing does nothing. I have to close kmail and restart. Is this related to some sort of wrong config of the shared mailboxes or is this a (known) dovecot <-> kmail problem? -- Wilhelm

[Dovecot] Shared mailboxes support status
by Thomas Hummel 26 Jan '09

26 Jan '09

Hello Timo, I'm running dovecot-1.1.8 and I'm about to play with namespaces and shared mailboxes. I've read on the list that the Kolab people did contribute to that, and I read at http://dovecot.org/doc/NEWS-1.2 "+ Full support for shared mailboxes and IMAP ACL extension." I'd like to know the differences between shared mailboxes support between 1.1. and 1.2 branches and if it may be considered "safe" to use shared mailboxes on a production server running 1.1.8+ dovecot version (i.e. is it working and how, compared to the upcoming 1.2 release). I guess part of the answer is in the diffences between shared and public namespaces handling.

[Dovecot] Postfix and Dovecot
by Leonardo Coelho 25 Jan '09

25 Jan '09

Hi Everybody, I'm mount two failover servers which use Postfix and Dovecot but the hostname of the machines r diferent: first node # uname -n # mail secound node #uname -n #mail2 So far so good, the real problem is that the e-mail file name on server is like this: 1232449377.P31789Q0M963611.mail2 and when I using the server called mail the file stay like this: 1232449377.P31789Q0M963611.mail I'm using drbd disk for the mailboxes and when I'm using the server called mail the files with mail2 on the end is not read for the dovecot when the user turn on the mail client but if I change the end from mail2 to mail that's ok the dovecot can read. How can I make dovecot read both files or any name on the end?

[Dovecot] Dovecot upgrade broke per-user Sieve scripts
by John Reese 25 Jan '09

25 Jan '09

Hi all, I'm migrating my private mail server from Dovecot 1.0.10 to Dovecot 1.1.4 (both the latest package in Ubuntu Hardy and Intrepid, resp.). I'm using Postfix with Postfixadmin virtual users , passing mail to Dspam, which in turn passes email to the Dovecot LDA. The relevant configuration section is attached below. When running on the old version of Dovecot, the LDA correctly executed either the user's personal sieverc script, or the global sieverc, as expected. However, after the upgrade to 1.1.4, Dovecot will not execute any per-user Sieve scripts, although the configuration and file permissions hasn't changed. I've added debug logging to Dovecot, and the relevant portions of the log file are also attached below. What am I missing here? Why can't cmusieve find the user's script? Did the configuration for Sieve change? I've read and re-read the Dovecot wiki page for Sieve, and I can't see why my configuration should be causing any troubles. All help or suggestions are greatly appreciated. Thank you. ### dovecot.conf protocols = imap imaps disable_plaintext_auth = no mail_debug = yes log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log mail_location = maildir:/srv/mail/%u/Maildir first_valid_uid = 900 ssl_cert_file = /srv/ssl/dovecot.pem ssl_key_file = /srv/ssl/leetcode.net.key auth default { mechanisms = plain login passdb sql { args = /srv/etc/dovecot/dovecot-mysql.conf } userdb sql { args = /srv/etc/dovecot/dovecot-mysql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0600 user = postfix group = postfix } } } protocol lda { log_path = /srv/mail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)leetcode.net mail_plugins = cmusieve sieve_global_path = /srv/mail/sieverc plugin { sieve = /srv/mail/%u/sieverc } } ### end dovecot.conf ### dovecot.log deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: jreese(a)leetcode.net deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: maildir=jreese(a)leetcode.net/ deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: uid=900 deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: gid=900 deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: maildir: data=/srv/mail/jreese(a)leetcode.net/Maildir deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: maildir++: root=/srv/mail/jreese(a)leetcode.net/Maildir, index=, cont> deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: /srv/mail/%u/sieverc doesn't exist deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: Using sieve path: /srv/mail/sieverc deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: Executing script /srv/mail/sievercc ### end dovecot.log -- John Reese LeetCode.net

[Dovecot] v1.1.9 released

23 Jan '09

http://dovecot.org/releases/1.1/dovecot-1.1.9.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.9.tar.gz.sig Lots of small dbox fixes, hopefully migrations from Maildir are now working correctly. I'm also planning on releasing v1.2.beta1 in a few days. + Sending SIGUSR2 to dovecot-auth now also logs statistics about cache inserts. This could help figuring out auth cache size. + deliver: Added rejection_subject setting, which is used for rejected mails. + pop3: Prevent clients from looping forever trying to fetch an expunged message. + If login process crashes, log the IP address that (maybe) caused it. + If core dump limit is 0, add "core dumps disabled" to startup log line. + Log better messages for "Permission denied" errors - mbox: Fixed assert-crash with pop3_lock_session=yes - dbox: Fixes to handling maildir-converted files. - Auth cache wasn't working correctly for all fields (e.g. allow_nets) with blocking passdbs (e.g. mysql). - pgsql: Handle reconnecting to server without failing auth lookups. - Berkeley DB memory/resource leak fixes. - maildir: Fixes to handling over 26 keywords.

Thanks Brandon. It seems I should try it out, especially given that using the dovecot LDA includes W= in the filename. I'll report back on this thread once testing is done.

[Dovecot] Sieve regex match problem
by Andy Howell 22 Jan '09

22 Jan '09

I'm trying to make a regex to match common mailing list addresses and file messages to corresponding folders. I'm using sieve-test to try and understand what is happening. The sieve script is: require [ "fileinto", "regex", "variables" ]; if header :regex ["Sender"] ["(.*>[ \\t]*,?[ \\t]*)?([^-@]*)-([^-@]*)(-bounces)?@antlr.org"] { fileinto "${0} :: 1:${1} 2:${2} 3:${3} 4:${4} 5:${5} 6:${6} 7:${7}"; } The email contains: Sender: antlr-interest-bounces(a)antlr.org I'm trying to form a folder from the first two parts of the sender. In the real script, that will do a "fileto antlr.interest;" Running sieve-test, I get: * store message in folder: antlr-interest-bounces(a)antlr.org :: 1: 2:antlr 3: 4:interest 5: 6:-bounces 7: I don't understand why parts 3 and 5 are empty. From the regex grouping, I expected Part 2 "antlr" Part 3 "interest" Part 4 "-bounces" The regex groups break done as: 1: (.*>[ \\t]*,?[ \\t]*)? - match leading name, comma or spaces 2: ([^-@]*) - match first part: 'antlr' in his case - - Hyphen between parts 3: ([^-@]*) - match second part: interest in this case 4: (-bounces)? - When cc'd, -bounces part isn't used The same regex tested with perl works as I expected. Without the first group of the regex '(.*>[ \\t]*,?[ \\t]*)?', it works correctly. That group isn't getting matched anyway, so it shouldn't matter. This is with 1.2alpha5. What am I missing? Thanks, Andy

[Dovecot] Migration question: .INBOX?
by Peter Lindgren 22 Jan '09

22 Jan '09

Hi, Not much left to fix in my migration script (moving between two dovecot servers). However, I discovered a mail folder .INBOX without cur, new and tmp subfolders, and the .imap.index files were rather old (feb 2006). Is this an old relic from early dovecot versions (I once ran 0.99 on this old server)? Or is it old client software? There are no data in it. TIA, Peter -- Peter Lindgren http://www.norrskenkonsult.com
