Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) and results in dire performance - plus there's a known crash vulnerability if files are repeatedly renamed in large directories (this bites us regularly...) GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

Re: [Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)

Cool, thank you Patrick! Must have missed that somehow. I put the setting in main.cf, "receive_override_options = no_address_mappings", right after 'content_filter' (running amavisd on a separate port) and it seems to have fixed the problem. -- Darek On Tue, Jan 18, 2011 at 7:05 PM, Patrick Westenberg <pw(a)wk-serv.de> wrote: > Darek M schrieb: > >> Anyone have an idea of what I should be looking at in a situation like >> this?

[Dovecot] Pigeonhole 2.2 build issue on arm
by Tom Talpey 19 Jan '11

19 Jan '11

When building Pigeonhole 2.2 for ARM, the following warnings are produced: uri-mailto.c: In function '_parse_hex_value': uri-mailto.c:139: warning: comparison is always false due to limited range of data type uri-mailto.c:145: warning: comparison is always false due to limited range of data type The problem is a test assuming that char is a signed type : static inline int _decode_hex_digit(char digit) { ... static bool _parse_hex_value(const char **in, char *out) { char value; // <<--- change to "int". if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; *out = value << 4; (*in)++; if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; This is untested, but I changed the "char value" to "int value" to correct the signed comparisons. There are no warnings when building for x86 in either case, btw. Also, the two tests for "**in == '\0'" seem to be unnecessary?

[Dovecot] Problem with seeing mail after Upgrade from Courier
by apettitt 19 Jan '11

19 Jan '11

I created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no issues. The issue I'm having now is that Dovecot is not seeing any mail in the user's directory. If I create a new user, it can send and receive mail with no problems. If I send an email to an existing user, it gets delivered to the new folder but dovecot does not see anything in the new folder. There is also mail in the curr folder that dovecot does not see. I'm using Roundcube as a webmail client but I've also tried using Telnet with the same results. Any ideas? -- View this message in context: http://old.nabble.com/Problem-with-seeing-mail-after-Upgrade-from-Courier-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)
by Darek M 19 Jan '11

19 Jan '11

Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install. - If I set a forward for an account to go to a remote email address, no dupes. - If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address. So if account1(a)domain.com has account2(a)domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message. I will also get a duplicate if I forward mail to account(a)anotherdomain.com, where anotherdomain.com is also hosted on the same system. account1(a)domain.com receives one copy. Here is the Dovecot log: Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here. This is the entry for the account in the 'alias' table ======================== mysql> select * from alias where address='account1(a)domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1(a)domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 | Anyone have an idea of what I should be looking at in a situation like this?

Hi there, I changed postfix to pass email to spamassassin, and then deliver to dovecot LDA. It fails to deliver. The current entry in master.cf now reads: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} smtp inet n - - - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=nobody argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} This is the same as I had to afore I factored in spamassassin. The error message is this:- Jan 18 16:30:44 logout postfix/pipe[28952]: 56AE58230A: to=<test(a)test.info>, relay=dovecot, delay=0.01, delays=0/0/0/0.01, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] ) Does anyone know which options I should have added to dovecot deliver?

http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz.sig I'm still lagging behind in my email, but I guess it's time to release v2.0.9 anyway. - Linux: Fixed a high system CPU usage / high context switch count performance problem - Maildir: Avoid unnecessarily reading dovecot-uidlist while opening mailbox. - Maildir: Fixed renaming child mailboxes when namespace had a prefix. - mdbox: Don't leave partially written messages to mdbox files when aborting saving. - Fixed master user logins when using userdb prefetch - lda: Fixed a crash when trying to send "out of quota" reply - lmtp: If delivering duplicate messages to same user's INBOX, create different GUIDs for them. This helps to avoid duplicate POP3 UIDLs when pop3_uidl_format=%g. - virtual storage: Fixed saving multiple mails in a transaction (e.g. copy multiple messages). - dsync: Saved messages' save-date was set to 1970-01-01.

[Dovecot] Question about indexes and maildir/sdbox/mdbox
by Javier de Miguel Rodríguez 18 Jan '11

18 Jan '11

Hello We are now running dovecot 2.0.9 with indexes in a ram disk and maildir storage in a test system. We have the following questions: - If there is a power outage / kernel crash, we will lose the content of ramdisk. We have tested that indexes are regenerated when a user logs in via imap, so e-mail access will be "slower" after a power outage / kernel crash, but everything should work as expected (TM). Are we missing something? - We are evaluating migrating from maildir to dbox. There are two alternatives: sdbox and mdbox. Reading about dbox in the wiki (http://wiki2.dovecot.org/MailboxFormat/dbox) we see that using a ram disk for indexes for mdbox is a really bad idea: /"Note that with dbox the Index files actually contain significant data which is held nowhere else. Index files for both *single-dbox* and *multi-dbox* contain message flags and keywords. For *multi-dbox*, the index file also contains the map_uids which link (via the "map index") to the actual message data. This data cannot be automatically recreated, so it is important that Index files are treated with the same care as message data files."/ So in mdbox we should not use a ramdisk for indexes. But what about sdbox? sdbox indexes work as maildir indexes? Are sdbox indexes bigger than maildir indexes? Thank you very much for your support Regards Javier

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by Dave 17 Jan '11

17 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

This is pretty much what I do with the mail domain I administer. I've set the INBOX with a modest quota, and a personal mail folder with a generous quota. I encourage users to keep their INBOX as a "working set", and archive the rest using any method they prefer. It forces users to process their Email (or at least their INBOX). and keeps packratting in check. Super-big INBOX quotas seem to encourage wasteful habits. I've helped some users clean out their mailboxes and was surpised at the amount of junk being kept for years and years. Apart from a few users moaning about their meager INBOX, this policy works out fairly well. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual mailboxes do not look into subfolders

Hi all, I have virtual mailboxes set up as "Smart Folders" to show me messages tagged with certain keywords. For example: # ~/Maildir-virtual/fwp/dovecot-virtual File MailingLists/* KEYWORD @fwp Messages get picked up from the File mailbox, but not for the sub-mailboxes inside the MailingLists mailbox. What am I doing wrong? Wrong separator? And how can I debug this? Everything else is working fine. Thanks a lot! Paul

[Dovecot] vpopmail disabled services fix
by Calvin 17 Jan '11

17 Jan '11

I noticed that disabling services using vpopmail was not being recognized by dovecot. Using "vmoduser -swip user(a)domain.com" should disable all services, but both pop and imap logins were still allowed. After a bit of digging in the code and confirming with a few debug lines, it appears that lines 38 and 52 of src/auth/passdb-vpopmail.c are the issue (dovecot 2.0.8). These two lines do a strcmp on request->service. It appears that request->service is in lower case, but the comparison values are in upper case. Either updating the values to lowercase or using strcasecmp should fix the issue.

[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis

[Dovecot] [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
by Christian Wiese 16 Jan '11

16 Jan '11

Hi folks, attached is a trivial patch which is fixing Winbind/NTLM authentication in dovecot 2.0 series. The patch was made against 2.0.8 sources, but there should be no problem applying it onto HEAD, because 'src/auth/mech-winbind.c' wasn't touched for quite some time now ;) I tested the patch with a dovecot 2.0.8 running on linux, authenticating against a WindowsServer 2008R2 Enterprise using ntlm_auth/winbind (from current stable samba 3.5.6). I successfully tested NTLM authentication for IMAP and POP3 (with and without STARTTLS) using following MUAs for the test: - Thunderbird 3.1.7 (Linux X86-64) - Outlook Express 6.00 (Windows XP Pro Qemu-KVM) Cheers, Chris Patch Description: In changeset 9002 a new function named mech_winbind_auth_initial() was introduced, but only the mech_winbind_spnego module part was changed to finally use this function. The mech_winbind_ntlm module part was not properly adapted which leads to a non functioning NTLM authentication mechanism while using winbind, because it will never call the `ntlm_auth` helper. The simple fix is to replace mech_generic_auth_initial() with mech_winbind_auth_initial() as auth_initial "hook" when setting up the mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module. References: - Changeset 9002: http://hg.dovecot.org/dovecot-2.0/diff/9d0037a997f4/src/auth/mech-winbind.c

[Dovecot] Seeing other people subscribed non-shared mailboxes
by Thomas Hummel 16 Jan '11

16 Jan '11

Hello Timo, With dovecot-2.0.8/Maildir, in a simple shared mailboxes setting I noticed the following : - user "doveimap" has 2 mailboxes : "Common" and "Private" - he shares only the "Common" mailbox to user "dovepop" doing : x setacl "Common" dovepop lrwstipekxacd x OK Setacl complete. - he subscribed to both x lsub "" * * LSUB () "." "Trash" * LSUB () "." "Common" * LSUB () "." "Private" x OK Lsub completed. I'm not realy sure if the fact that "dovepop" can see doveimap's subscribed "Private" mailbox in the "#Shared" namespace is legitimate or not : x login dovepop xxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in x list "" * * LIST (\HasNoChildren) "."

"#shared.doveimap.Private" x OK Lsub completed. x logout Is this the way it's supposed to work ? My setup is : namespace { type = shared separator = "." prefix = "#shared.%%u." location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-2/indexes/%1u/%u/shared/%%u:CONTROL=/courriel/meta/%%u # Use the default namespace for saving subscriptions. # subscriptions = no # hidden = no # list = no list = children } # pwd /courriel/boites/doveimap # cat dovecot-acl-list 1294755382 Common # cat .Common/dovecot-acl user=dovepop akxeilprwts # cat .Private/dovecot-acl cat: .Private/dovecot-acl: No such file or directory Also, I'm not sure I correctly understand what "Use the default namespace for saving subscriptions." option is. Is it just the location of the subscription file for mailboxes subscribed in the shared namespace ? Where would it be if set to "yes" ?

Hi, I have a user called archive that gets a BCC of all incoming/outgoing email. I would like to have the email in the new/cur directories setup to be read only, is there a way to do this in dovecot 2.0.8. I know you can set the umask in the dovecot config but I believe this is a global setting. Thanks, Paul

[Dovecot] Rename public folders
by Burian, John 16 Jan '11

16 Jan '11

I've got a number of public mailboxes configured for my users. We pretty much have to use Entourage for a client, which insists on creating all new subfolders with the name 'Untitled Folder'. When they try to rename these subfolders with useful names, Dovecot returns A028 NO [CANNOT] Renaming not supported across non-private namespaces. I guess this is because renaming a subfolder could potentially break subscriptions for other users? Or is it a hard requirement from IMAP RFC? If the former, is the problem merely very complicated, but eventually fixable, or is it just intractable? We're using Dovecot 2.0.7 from the atrpms RPM, Redhat EL 5.0. The public mailbox namespace is configured with: namespace { type = public prefix = Public/ separator = / hidden = no list = yes inbox = no subscriptions = no location = maildir:/data/imapmail/public:LAYOUT=fs } -- John Burian Systems Programmer Battelle Center for Mathematical Medicine The Research Institute At Nationwide Children's Hospital 614-355-5686 John.burian(a)nationwidechildrens.org ----------------------------------------- Confidentiality Notice: The following mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

In the real world of an ISP, killing 99% of all spam before it hits the storage is unthinkable. We only block spam that is guaranteed to be unwanted, mostly based on technical facts that can't ever happen in normal email. But email that our scanning system flags as probable spam, is just that, probable spam. We can not just throw that away, because in the real world, there are always, and I mean always, false positives. It is unthinkable to throw false positives away. So we have to put these emails in a spam folder in case the user wants to look at it. We block about 40% of all spam on technical grounds, our total spam percentage is 90%, so still about 80% of all customer email reaching the storage is spam. > > But in other environments throwing away all probable spam may be perfectly fine.

Currently mostly in database servers, but our experiences have been good enough that we're slowly starting to add them to more systems as even boot drives. But we're not using them yet in email storage. Like Brad we're using Netapp filers because as far as I know they're one of the few commercially available HA filesystem companies. We've looked at EMC and Sun as well, but havent found a reason to move away from Netapp. In 12 years of netapp we've only had 1 major outage that lasted half a day (and made the front page of national news papers). So, understand that bit. Major outages make it to national news papers for us. HA, failover, etc are kind of important to us. > > So why not build something ourselves and use SSD? I suppose we could, but it's not as easy as it sounds for us. (your mileage may vary). It would take significant amounts of engineering time, testing, migrating, etc etc. And the benefits are uncertain. We dont know if an open source HA alternative can give us another 12 years of virtually faultless operation. It may. It may not. Email is not something to start gambling with. People get kind of upset when their email disappears. We know what we've got with Netapp. > > I did dabble in using SSD for indexes for a while, and it looked very promising. Certainly indexes are a prime target for SSD drives. But when the director matured, we started using the director and the netapp for indexes again. I may still build my own NFS server and use SSD drives just for indexes, simply to offload IOPS from the Netapp. Indexes are a little less scary to experiment with. > > So, if you're in the position to try out SSD drives for indexes or even for storage, go for it.

Hi all, Is there anywhere a complete list with the build dependencies for Dovecot? A list with all the libraries/binaries that are required to build dovecot from source with support of all its features. Thank you, Buzai

[Dovecot] Can I get rid of the fchown log messages?
by Maarten Bezemer 16 Jan '11

16 Jan '11

Hi, Since upgrading dovecot version (from somewhat ancient to 1.2.16), I see messages in the logs like these: Jan 15 00:55:17 srv0303 dovecot: POP3(obm03): fchown(/home/obm/obm03/mail/.imap/INBOX/dovecot.index.tmp, -1, 8(mail)) failed: Operation not permitted (egid=1033(obm), group based on /var/mail/obm03) I know that this is because the mailbox in /var/mail has ownership username:mail. However, in this setup this is intentional, and quota-related (quota on inbox is enforced by Exim, not Dovecot, and kernel does group-quota but not for group mail). Also, group read rights for group mail are intentional. >From what I read on this list, it has something to do with shared folders. I did not (at least it wasn't my intention) configure users' inboxes as shared folders. So, is there a way to disable these log messages, or, to disable Dovecot's attempts to try to change the owner/group of the index/cache/log files when these are inside the user's private ~/mail folder? More specifically, is there a way to do this without changing anything to users' inbox permissions? Thanks, Maarten

[Dovecot] fs quota backend bug
by Jan Škoda 16 Jan '11

16 Jan '11

Hi, I maintain postfix mailserver with sudo enabled dovecot LDA using multiple uids. I want to enforce quotas per-unix-user (which can have multiple domains with multiple emails set up using postfixadmin), so I have set up a FS quota backend with imap_quota plugin. Unfortunately, the quota appears to work (when i disable chrooting) according to dovecot-info.log, but doesn't send anything over IMAP.

I've checked my setup - the guest is not set to sync with the VMware host. NTP is running with local clock server commented out & 'tinker panic 0' set. It sounds like this is not a Dovecot issue so I'll stop posting to this list now and seek help elsewhere. What negative effects to Dovecot would I expect to see where the system clock is constantly changing?

[Dovecot] Check if a message has attachments
by Antoine Nguyen 14 Jan '11

14 Jan '11

Hi all, my question is not specific to Dovecot but to the IMAP protocol in general. I'm working on a web based software that provides a simple webmail ( http://modoboa.org/) I'm wondering what would an efficient way to detect if a message (or a group of messages) has attachments. I know it certainly consists in checking for specific MIME constructions but how to achieve that without fetching the whole body for each message? Thanks in advance, Antoine Nguyen

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by David Salisbury 14 Jan '11

14 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

Thanks, I've read through that document a couple of times now & I'm fairly sure my system 'ticks all the boxes' yet the warning messages continues. I can see no noticeable time discrepancy when I do periodic time checks from the command line comparing against another system's clock - certainly not 2 minute error margin Could this be a time mismatch between imap client & server?

[Dovecot] email addresses as usernames with Kerberos
by Peter Mogensen 14 Jan '11

14 Jan '11

Hi, I was trying out Kerberos authentication with som sample users for Dovecot and stumbled into this problem: The user names are of the form local-part@domain, so the Kerberos principal becomes "local-part\@domain@REALM". But it seems Dovecot (1.2.9) doesn't understand that syntax. Looking at the 2.0.8 sources I guess it's not supported. But isn't this a valid Kerberos principal? Is it a bug, or a missing feature or is there a special reason for not supporting it ? kind regards, Peter

Running Dovecot 2.0.8 on 32bit Centos5.5. The machine is a VMWare ESX VM.

NTP is running and not complaining about clock drift. Vmware recommend appending 'divider=10 clocksource=acpi_pm' kernel boot options to prevent timekeeping issues, which I've done. Has anyone else encountered this message? Is it something to be concerned about? Thanks, Ian.

Re: [Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

Well, I just noticed this in my logs after I re-loaded the latest Dovecot config I tried: Jan 13 15:09:45 mail dovecot: SIGHUP received - reloading configuration Jan 13 15:09:45 mail dovecot: read(imap dump-capability process) failed: Interrupted system call Jan 13 15:09:45 mail dovecot: Invalid configuration, keeping old one Jan 13 15:09:45 mail dovecot: child 2085 (unknown) returned error 82 (Internal logging error) It's apparently been doing this every time I've reloaded the config, so this is probably why none of my changes with the ACLs are working. :/ Any thoughts on what could be causing this kind of error?? Does that error just basically mean something's set wrong somewhere in dovecot.conf? David

The 3.x branch is rock solid. There have been no crashes (yet!) Would DRBD + GFS2 work better than NFS? While NFS is simple, I don't mind experimenting with DRBD and GFS2 is it means fewer problems?

[Dovecot] Denying authentication
by Romer Ventura 13 Jan '11

13 Jan '11

Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can close everything since there are a few users that need to get emails from outside the company via cell phone of email clients. I was thinking if there was a way to lets say create a group in AD named: "remote-email" that will allow connection and authentication from any network, any user not in that group will only be able to authenticate if the source is 192.168.xx.xx/24. Is this possible? Maybe not with Dovecot, but maybe someone else has any ideas..? Thanks -------- Romer Ventura

[Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

I have set up an area of shared folders with Dovecot 1.2 that is accessed by several people (by way of one account, and everyone who logs in sees these same folders), and the only problem with this setup is that occasionally somebody moves one of the folders underneath another folder or somewhere else in the folder structure, and this sometimes disrupts some automatic procmail filters and the like. Is there a way to keep folders in a shared setup such as this "static" or "unmovable" so that the users can't disrupt the structure? Like, where the folder structure itself can't be changed, but new messages can still come in to the folders? David

[Dovecot] How do folk . . . Aggregate system mail from LAN machines?
by Ron Leach 12 Jan '11

12 Jan '11

List, good evening, Running Dovecot for external email, but not yet worked out how (best) to aggregate 'system' mail from other machines on the LAN. By system mail, I mean mails generated by the OS or by applications, and addressed to root, or 'some admin user', etc. Ideally, these would be seen by 'root' or 'some admin user' or whoever on our existing Dovecot/IMAP system. Our scale is not large, we only have 5 servers on the LAN doing various things. I wondered how other Dovecot users do this. I've thought of 3 possibilities: 1. Install Dovecot on each LAN machine, and use Fetchmail to retrieve the messages using POP so that local mail stores were emptied. 2. Perhaps, use a 'forwarding' mechanism of some sort on each LAN machine, but that would require an MTA on each LAN machine, would it not? 3. I wondered whether /etc/alias, mentioned in a recent post by Simone Caruso, might help though again, presumably, requiring an MTA on each LAN machine. What do you do? regards, Ron

[Dovecot] Question about lda & auth_socket_path
by Jahnke-Zumbusch, Dirk 12 Jan '11

12 Jan '11

Hi all, storing e-mails (using postfix) via dovecot-lda fails and I assume this is related with a auth_socket configuration problem. But I am at a dead end, so perhaps anybody has got a hint for me: This is dovecot-2.0.8 on Solaris 10: 10-auth.conf and its include: ----------------------------- ... userdb { driver = static args = uid=104 gid=104 home=/some/path/%u } Relevant parts of 10-mail.conf: --------------------------------- ... auth_socket_path = /var/run/dovecot/auth-userdb Relevant parts of 10-master.conf: --------------------------------- ...service auth { unix_listener auth-userdb { mode = 0644 user = vmail #group = } } service auth-worker { user = root } Relevant parts of 15-lda.conf: --------------------------------- ... protocol lda { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins } # ls -l /var/run/dovecot/auth-userdb srw-r--r-- 1 vmail root 0 Jan 12 15:49 /var/run/dovecot/auth-userdb Using dovecot-lda for mail delivery or doveadm for user inquirement fails: via debug_log_path: ------------------- Jan 12 16:04:14 auth: Debug: Loading modules from directory: /dovecot/code/dovecot-2.0.8/lib/dovecot/auth Jan 12 16:04:14 auth: Debug: passwd-file /store1/db/masterusers.passwd: Read 1 users Jan 12 16:04:14 auth: Debug: master in: USER 1 djahnke service=lda Jan 12 16:04:14 auth: Debug: password(djahnke): passdb doesn't support credential lookups Jan 12 16:04:14 auth: Debug: master out: FAIL 1 Jan 12 16:04:14 lda: Debug: auth input: via syslog: ----------- Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] auth: Error: static(djahnke): passdb doesn't support lookups, can't verify user's existence Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] lda: Error: user djahnke: Auth USER lookup failed Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.crit] lda: Fatal: Internal error occurred. Refer to server log for more information. When I use "allow_all_users=yes" everything works fine, so I think somehow the communication with the socket fails. I cannot see what I have missed :-( Any suggestions what I should look for / configure ?

[Dovecot] mail quota dovecot 1.2.15-3
by J4 12 Jan '11

12 Jan '11

Dear all, I am attempting to enforce quota with Dovecot 1.2.15-3 using LDA for deliver. I use smtp-source (postfix) to deliver large messages but the quota is never noticed. The webmail interface is Roundcube, and the admin is performed using Postfixadmin. I have not looked into the postfix portion for quota, yet. Is there something that I have missed from the configuration?

[Dovecot] Refilter Mailboxes via Sieve - Missing delivered-to header
by Dieter Knopf 12 Jan '11

12 Jan '11

Hello, i already read http://wiki.dovecot.org/HowTo/RefilterMail but it won't work here :( I have many old mails in my folders and need to refilter many of them. But there are many mails without a delivered-to-header. What can i do? Error: Configuration error: envelope_recipient specified header missing (delivered-to:1) Would be okay if getmail would just skip the mail, but it cancels. Not sure if there is any way around. This is the config: [retriever] type = MultidropIMAPSSLRetriever envelope_recipient = delivered-to:1 server = foo port = 993 username = foo password = foo mailboxes = ("INBOX.REFILTER",) move_on_delete = INBOX.trash [destination] type = MDA_external path = /usr/lib/dovecot/deliver arguments = ("-e", "-f", "%(sender)", "-d", "%(recipient)") user = vmail group = vmail [options] delete = true recieved = false delivered_to = false verbose = 2 I'm using virtual users, so i must use Multidrop. Thanks

[Dovecot] Connection queue full on my directors
by Jan-Frode Myklebust 11 Jan '11

11 Jan '11

I finally upgraded to v1.2.16 on my backend servers, with ldap instead of previously mysql, and put a couple of dovecot v2.0.8 directors in front of them (used haproxy previously). It seemed to work OK initially, but after a few hours we got bit by "Connection queue full" problems on the directors. So I now set default_process_limit=512 and also: service anvil { client_limit=1027 } since dovecot said that was now required. Things seems to be working, but I'm afraid default_process_limit=512 is too low: $ ps -ef|grep dovecot/pop3-login|wc -l 192 $ ps -ef|grep dovecot/imap-login|wc -l 472 so looks like I'm quite close to hitting this limit for my imap logins. We will eventually put up some webmail servers (using imapproxy to keep connections alive), that will be connecting over these directors. Then we will expect to have a lot more active imap sessions over these directors. Should we just keep increasing default_process_limit, or per service process_limit, and follow dovecots warnings about client_limits for auth/anvil.. or will we be getting into other problems like running out of file descriptors? Are there any max'es we should expect to run into ?

[Dovecot] Dovecot - AllowGroups option
by Jacob Neergaard Pedersen 11 Jan '11

11 Jan '11

Hi, I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage. Services like proftpd have: "AllowGroup ftpgroup" sshd have "AllowGroups sshgroup" And samba have "valid users = @smbgroup" But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf) Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password? (I know its needed for samba but besides that) /Neergaard

[Dovecot] utility to copy/sync IMAP mailboxes
by Don Buchholz 11 Jan '11

11 Jan '11

Well, my Dovecot server (v2.0.8) is up and running, and now it's time to migrate mailboxes from the old mail server [Lotus Domino Release 5.0.8] running on Windows NT 4.0 [ancient -- been the mail server since Aug-2000]. I saw "dsync(1)" and thought my troubles were over. Only I can't figure out how to make it work with the NT/Domino server as a source for mailboxes. I guess dsync(1) works only in completely *nix environment. I've been trying the imapcopy.pl script from the IMAP Tools web page (http://www.athensfbc.com/imap_tools/) but it is having problems with Notes' choice of the backslash (\) character as a mailbox (namespace?) delimiter. Any suggestions for a stable, reliable (copy/duplicate/mirror/sync) tool that can do the job using only IMAP access? (No SSL support required.) Thanks in advance, - Don

[Dovecot] Max number of mail processes
by Patrick Nudo 11 Jan '11

11 Jan '11

Dovecot version 1.1.11. Error: Maximum number of mail processes exceeded (see max_mail_processes setting). I can't seem to get rid of these errors. I get batches of these errors about 4 or 5 times a day. I have a cron-job checking for the existence of this error and then I reboot dovecot when I see this error, but what is causing this error ? What I am reading on the Internet about this particular issue has not helped to resolve the issue. I would really like to know how many mail processes it thinks that it is using at any one instant in time. Is this possible ? Maybe then I can track the reason for the error.

[Dovecot] enforce STARTTLS on port 110 with POP3?
by Zhou, Yan 11 Jan '11

11 Jan '11

Hi there, We are using DoveCot 1.0.7. User will use POP3 or POP. We want to force user to securely send their credential and keep a secure connection between us and them. We can do TLS/SSL on port 995, or STARTTLS on port 110. The problem is that we have no way to enforce STARTTLS on 110, user can connect to DoveCot on port 110, sending user credential without STARTTLS (thus insecure). Reading DoveCot documentation does not sound it supports this. Here is what I got from documentation. Dovecot supports: * IMAP (including TLS/STARTTLS) * IMAP+SSL ("imaps") * POP3 (including TLS/STLS) * POP3+SSL ("pops") My only option to enforce securely sending user credential is to enable port 995 and disable port 110, sound right?

[Dovecot] Multiple Authentication Databases
by Jonathan Tripathy 11 Jan '11

11 Jan '11

Hi Everyone, I wish to run Dovecot on my "Front End" outbound mail relay, and use Dovecot purely for authentication purposes. However, each mysql database for each domain will be on a separate server. Is there a way for dovecot to authenticate against different databases depending on domain name? Thanks

[Dovecot] OS X Server Partition Problems
by Bryan Harrison 11 Jan '11

11 Jan '11

I'm a nube to Dovecot and this list. Please be kind. ;) I'm running Dovecot 1.1.20 and Postfix 2.5.5 on OS X Server 10.6.6. I've moved accounts from another, older cyrus-based server (thank god), and used fetchmail to imap the existing mail to the new server. At some point, I developed a problem with my partition map being semi-ignored. Mail is stored in multiple places, and I'm not sure why or entirely clear how it ended up there. My log is overflowing with entries such as… Jan 10 15:44:57 gilded-bat dovecot[65]: auth(default): od(john_doe_com): unable to find partition for tag=johndoe: using default mail location: /var/spool/imap/dovecot/mail …referring to each of my defined partitions. Here's what I semi-understand. /etc/dovecot/partition_map.conf.default contains: default:/var/spool/imap/dovecot/mail /etc/dovecot/partition_map.conf contains correct entries like default:/Mail JohnDoe:/Groups/JohnDoe/Mail [etc.] dovecotd -n is below. It's configuration with regard to mail store locations look ok to me, but then I'm a virgin. In practice, mail is being stored in three different locations. They're all full of mail directories and are busy. /var/spool/imap/dovecot/mail /Mail /Groups/JohnDoe/Mail …with of course the third entry being many entries for each client. The directories described definitely exist. Clients started out being able to see old mail that was transferred from the retired server, but no longer do. I'm not actually clear which of the three mail stores in use are being accessed by whom or for what. (And let's not even ask why none of this showed up in testing.) In short, I'm over my head and the villagers are outside with the usual pitchforks and torches. Thanks, Bryan dovecotd -n # 1.1.20apple0.5: /private/etc/dovecot/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 356).

[Dovecot] dsync not copying all mail
by Nick Rosier 10 Jan '11

10 Jan '11

Hi, I'm still trying to migrate from Dovecot 1.2.16 to 2.0.7 on FreeBSD. Previous attempts have failed with mails not being visible after the upgrade. Version 1.2.16 was migrated from maildir to dbox about a year ago via the convert-plugin. After previous attempts to "clean" the hybrid maildir-dbox situation I used imapsync to copy all mails from the old account to a new account. I would assume in this case I get a clean dbox-mailmap. I tried to run dsync on this new map but noticed a lot of mails are not syncing: [vmail@mail ~]$ find /vmail2/new/bunbun.be/nick | wc -l 5329 [vmail@mail ~]$ find /vmail2/old/bunbun.be/nick | wc -l 6134 Any ideas? N.

[Dovecot] Last login
by Egbert Jan van den Bussche 10 Jan '11

10 Jan '11

Hi, I'm trying to find a way to find inactive users. Is there a simple way to deduct the last login date of a user from that users Maildir files? Are the timestamps on the index files reliable? I ask because the system and dovecot logs are not available to me but I can search the whole .../vmail/domain/user/Maildir tree. I'n running 1.2.9 on ububtu 10.04 LTS with posttfix and postfixadmin. The users (all are virtual) reside in the postfixadmin MySQL tables. TNX Egbert Jan (NL)

[Dovecot] Urgent problem: Dovecot fetches the same mails multiple times per POP
by Andi Meier 10 Jan '11

10 Jan '11

I have a problem since a couple of hours: I manage several mboxes on a virtual server using Dovecot (over POP3). Until a few hours ago, it worked well, but since 11:50, the e-mail clients which access Dovecot's mailboxes, receive all e-mails new each time the mailbox is queried. For example: 15:40 fetches 22 new mails 15:41 fetches the same 22 mails again as new 15:42 fetches the same 22 mails again as new etc. Dovecot version is 1.0.15 on Debian Lenny. How can I fix this? How can I diagnose what's wrong? The mailbox files themselves seem ok, no dupe messages. I noticed that in the /var/log/mail.log Dovecot says: ------- START --------- Jan 10 15:27:08 lvps87-230-81-99 dovecot: POP3(office): Disconnected: Logged out top=0/0, retr=23/6273313, del=23/23, size=6272894 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): Effective uid=1002, gid=1002 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox: data=/var/mail:INBOX=/var/mail/office Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox: root=/var/mail, index=/var/mail, inbox=/var/mail/office Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: Expunged message reappeared in mailbox /var/mail/office (UID 3234 < 3261, seq=2, idx_msgs=0) Jan 10 15:40:02 lvps87-230-81-99 dovecot: pop3-login: Login: user=<office>, method=PLAIN, rip=80.122.113.70, lip=87.230.81.99 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3261 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3285 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:22 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3309 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:22 lvps87-230-81-99 dovecot: POP3(office): Disconnected: Logged out top=2/0, retr=24/6274745, del=24/24, size=6274309 ------- END --------- What puzzles me: Each time the retr=XX value is never decreasing. Shouldn't it be 0/xxxxx the next time when the mails are not kept on the server? Apparently Dovecot does not manage to remove the mails form the mbox, although the email client tells it so (=> del=24/24) Is this the problem? How can I check this? I am very thankful for any hints! Cheers, Andi

[Dovecot] size of "m.XXX" in mdbox
by Joan Moreau 10 Jan '11

10 Jan '11

Hi, How to tune the size of each "m.xxx" file in mdbox format , in order to optimize the ratio size/number of files ? (I can see for instance more than 100 000 files in one directory due to very large mailbox size) If such parameter exists, what is the typical value ? Thanks Joan

Or use sendmail binary from something else than Courier. Yes i'm using sendmail from Courier. When i changed sendmail_path to original sednmail binary it's working and vacation is sent, but i can see some errors from sendmail.

[Dovecot] CatchAll virtual user removes spamheaders
by Peter Reinhold 09 Jan '11

09 Jan '11

Hi all, I am having a small problem with a catch-all user I have setup in my Postfix/Dovecot setup. I am not 100% sure this is Dovecot related, but, logic tells me it is. I have a virtual user called @reinhold.dk setup to redirect to my main account, peter(a)reinhold.dk. If I send a spam mail (GTUBE) to peter(a)reinhold.dk, the mail is marked with Amavis x-headers as it should be. If I send the same mail to peterpeter(a)reinhold.dk, I can see in my maillog that the mail is PASSED SPAMMY, just as the first one, but when I check the mail, all amavis x-headers are missing. (Except one, X-Spam-Virus-Scanned:, which just informs me that the mail has passed through the scanner) Does anyone know if this is a Dovecot issue? (It seems so to me), and if so, any hints on how I can change this behaviour? Kind Regards, Peter Reinhold - peter(a)reinhold.dk > http://www.reinhold.dk & http://www.geekhouse.dk < -- QOTD : Mit internet er der ikke noget porn på .. Det er helt vildt nederen. ..

[Dovecot] can not receive external emails
by Daminto Lie 09 Jan '11

09 Jan '11

Hi, I am new to Dovecot. Recently I have got a new server running on Ubuntu Server 10.04 with Postfix, Dovecot (for IMAP) and Squirrelmail. During the test, I was able to send & receive emails internally, and can send emails externally. However, I got a problem when it comes to receiving emails externally. The emails I sent from yahoo never arrived to my local inbox. Anyway, I checked the mail.log and found the following dovecot: auth-worker(default): dovecot-auth: /usr/locallib/liblber-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap_r-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap-r-2.4.so.2" no version information available (required by /usr/lib/libpq.so.5) I was wondering if anyone might be kind to explain the above error messages and how to work around this so that it could send/receive emails coming from external mail server. Thank you in advance

[Dovecot] IMAP Clients can not see 3rd tier nested IMAP directories
by jjs87＠cornell.edu 08 Jan '11

08 Jan '11

I have a very bizarre problem that I hope someone can help me with. I am not sure if this is a Dovecot problem, or IMAP client problem. I recently used Transend's Migrator to move mail from Exchange 2007 to my Dovecot 1.0.7 server. The program seems to have moved the nested IMAP dirs properly as seen below in a directory listing of the maildir dir. The nested dirs have indexes, cur, new dirs as expected. However, when the account is viewed in Windows Thunderbird 3.1.6 or Outlook 2010 the 3rd tier dirs are not seen, nor can they be subscribed to. On a whim, I decided to try Apple Mail 4.3 to view the account and all the IMAP dirs can be seen and accessed as expected. Any idea what is going on? Is this somehow an IMAP client problem (bug) or an issue with Dovecot and these clients? Listing of the Maildir dir: [root Maildir]# ls -al total 92 drwx------ 17 andrew andrew 4096 Dec 6 17:06 . drwx------ 9 andrew andrew 4096 Dec 6 15:58 .. drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox.mail drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues drwx------ 5 andrew andrew 4096 Dec 6 17:02 .mailbox.mail.colleagues.amy drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues.aslan drwx------ 2 andrew andrew 4096 Dec 6 16:31 cur -rw------- 1 andrew andrew 144 Dec 6 16:31 dovecot.index -rw------- 1 andrew andrew 10272 Dec 6 16:31 dovecot.index.cache -rw------- 1 andrew andrew 128 Dec 6 16:31 dovecot.index.log drwx------ 2 andrew andrew 4096 Dec 6 16:31 new drwx------ 5 andrew andrew 4096 Dec 6 16:53 .Sent Items -rw------- 1 andrew andrew 32 Dec 6 17:06 subscriptions drwx------ 2 andrew andrew 4096 Dec 6 16:31 tmp drwx------ 5 andrew andrew 4096 Dec 6 16:32 .Trash PROBLEM: When viewed in Thunderbird 3.1.6 or Outlook 2010: These nested dirs are seen: ..mailbox ....mail These nested dirs are NOT seen or can be subscribed: ......colleagues ........amy ........aslan OBSERVATIONS: When viewed in Apple Mail 4.3, all dirs are seen correctly.

[Dovecot] Migrate dbox 1.2 virtual mail to 2.0
by Nick Rosier 08 Jan '11

08 Jan '11

Hi, I'm trying to migrate from Dovecot 1.2.16 to 2.0.7. Initially the mails were stored in Maildir format but I changed them to dbox using "fast Maildir migration" and some mails are still in the old maildir format. I'm trying to migrate these mails using dsync but dsync panics: % dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror dbox:/var/spool/vmail2/bunbun.be/nick ...... dsync(vmail): Panic: file mail-storage.c: line 1351 (mailbox_save_set_guid): assertion failed: (guid == NULL || *guid != '\0') zsh: abort (core dumped) dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror Any ideas?

[Dovecot] Pointers for developing a proper encryption plugin?
by dovecot＠moorooboorai.com 07 Jan '11

07 Jan '11

Hi all, One thing that's always itching when I think about mail-servers, is the storage of e-mail messages in (rather) plain-text. Meaning, any administrator with sufficient privileges would be able to read messages not meant for them. Of course, PGP alike solutions exist, but that's not for the masses. In my opinion I would like to have e-mail messages stored encrypted using a (strong) user-supplied password. That password would ideally be the same as the one the user logs in with. So for me it's okay to place and enforce that requirement on any of the users. Having this in place would for sure reassure external auditors/accountants of any kind. Having Google'd from here to 'yonder and consulting experts on Experts Exhange, I have come up with only this pointer: http://dovecot.markmail.org/search/?q=dovecot+encrypt#query:dovecot%20encry… It mention the same issue, and also mentions the non-existence of a solution (back in May 2010). But, beforing diving into developing solutions myself, I have to be absolutely sure that there isn't any solution yet. And, in consequence of non-existence: what would allow me to fasttrack any development efforts on this? Is there an overview available where I could learn the best approach for plugin development? Tutorials maybe? Kind regards, Jeroen Zuijderhoudt.

Hi, Sorry. This is what I find when I try to run Dovecot. # dovecot -F Segmentation fault If I comment out the SSL configuration values, then: # dovecot -F doveconf: Fatal: Error in configuration file /opt/etc/dovecot/dovecot.conf: ssl enabled, but ssl_cert not set These are the configure options, "--enable-maintainer-mode" & "--enable-devel-checks" were added with the hope that dovecot would produce a more verbose error message. ./configure --prefix=/opt --with-ssl=openssl --disable-dependency-tracking --enable-maintainer-mode --enable-devel-checks None of the log files have been touched since before this version of Dovecot was installed (logging was initially part of the configuration).

[Dovecot] dovecot can't see mail that is there
by Joachim Ferreira 07 Jan '11

07 Jan '11

I used to install dovecot on any Fedora fresh installation and I could fetch my internal mail few minutes later. Now I've been struggling for two days and I haven't got my mail working yet. I have Fedora 14 with sendmail. Some application on the same machine send mail to an account on the same machine (hence all is confined to one machine) and I want to retrieve it from a laptop on the same LAN via Outlook. If I login into the account and check the mail with the alpine (ex pine) client, I see that there are 10 mails. When I "telnet localhost pop3" and login into the account, the "list" command says there are 0 mails. Various suggestions found on the internet for slightly different configuration did not help. All the help will be very much appreciated.

[Dovecot] dsync backup errors with maildir -> mdbox
by Patrick McLean 06 Jan '11

06 Jan '11

Hi, In preparation for a migration from maildir to mdbox, I am using dsync backup to do initial mailbox copies (at this point I do not want to risk any changes to the maildir). The initial run of dsync runs fine, but a second run to migrate any changes since the first run produces errors for many users. Here is an example of the type of error produced: > # dsync -u user backup mdbox:~/mdbox > # dsync -u user backup mdbox:~/mdbox > dsync(user): Error: Can't delete mailbox INBOX: INBOX can't be deleted. > dsync(user): Error: Can't delete mailbox directory XXXXXX.courses: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX.XX1: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX.XX2: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXXXX: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXX: Mailbox has children, delete them first > dsync(user): Error: Trying to open a non-listed mailbox with guid=c0204a140fdd254d1a770000743562c1 > dsync(user): Error: msg iteration failed: Couldn't open mailbox c0204a140fdd254d1a770000743562c1 > dsync(user): Error: Trying to open a non-listed mailbox with guid=c0204a140fdd254d1a770000743562c1

[Dovecot] Alternative storage vs. Self healing (losing flags?)
by Marczisovszky Daniel 06 Jan '11

06 Jan '11

Hi, We are going to set up an environment for our customers where the storage is provided by two servers. First one stores the new emails, second one stores all the others using Dovecot's alternative storage feature (mailbox format is mdbox). The servers are connected via NFS. If, for any reason, the alternative storage is not mounted, Dovecot will see only an empty folder and due to its self-healing functionality flags for messages stored on alternative storage will be lost. Is there any way to prevent regenerating indexes (and especially flags as a side-effect) if the alternative storage seems to be completely empty? (like a dummy file in the root of the alternative storage and an option to enable/disable this check) Thanks in advance, Daniel Marczisovszky

[Dovecot] Login with firstname.lastname instead of loginname - WORKING
by Ralf Hildebrandt 06 Jan '11

06 Jan '11

3 years ago (!) I aksed about this and finally I implemented it today: >> # NEW >> passdb { >> driver = passwd >> # firstname.lastname@charite.de:password:uid:gid:(gecos):home:(shell):user=realloginname >> args = /usr/local/etc/dovecot.login_via_email >> } >If you're only using it as a passdb, you don't need the uid/gid/home. So >an example field would be: > >firstname.lastname@charite.de:password::::::user=realloginname But now I'm encountering problems with users writing Firstname.Lastname(a)charite.de instead of firstname.lastname(a)charite.de (capitalized first letters) How can I "normalize" the usernames by lowercasing them? The coolest solution would be to strip realms AND force lowercasing of usernames in one pass -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Upgrade from 1.2.16 with sieve/managesieve to 2.0.8 with pigeonhole
by Nick Rosier 06 Jan '11

06 Jan '11

Hi, I would like to upgrade my server from 1.2.16 with sieve and managesieve to 2.0.8 with pigeonhole. Will I get all functionality I was having before? Should this migration be painless or will it require some additional work? I've read the Upgrading guide so I know I need to create an additional user. I've migrated the mails from Maildir to dbox in the past (using the convert plugin); does that mean I'm fully dbox or am I in a maildir-dbox hybrid situation? I've noticed that there are still some maildir-formatted mail (e.g. 1259960330.M322229P62710.mail,W=2195:2,S) in some of the maps. root@mail /usr/local/etc # dovecot -n # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-PRERELEASE amd64 zfs protocols: imap imaps managesieve ssl_ca_file: /etc/ssl/cert.pem ssl_cert_file: /etc/ssl/mail.crt ssl_key_file: /etc/ssl/mail.key version_ignore: 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(managesieve): /usr/local/libexec/dovecot/managesieve-login valid_chroot_dirs: /var/spool/vmail mail_max_userip_connections(default): 50 mail_max_userip_connections(imap): 50 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_uid: 5000 first_valid_gid: 5000 mail_privileged_group: mail mail_location: dbox:/var/spool/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): acl imap_acl fts fts_squat autocreate mail_plugins(imap): acl imap_acl fts fts_squat autocreate mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve 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(managesieve): dict_db_config: /usr/local/etc/dovecot-db.conf namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)xxx.xxx mail_plugins: sieve acl mail_plugin_dir: /usr/local/lib/dovecot/lda deliver_log_format: msgid=%m: %$ sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login cram-md5 username_format: %Lu passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.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: vmail group: vmail plugin: acl: vfile:/usr/local/etc/dovecot/acls:cache_secs=300 acl_shared_dict: file:/var/db/dovecot/shared-mailboxes.db convert_mail: maildir:/var/spool/vmail/%d/%n expire_dict: proxy::expire expire: Trash 365 sieve: /var/spool/vmail/%d/%n/dovecot.sieve sieve_dir: /var/spool/vmail/%d/%n/sieve sieve_global_dir: /usr/local/etc/dovecot/sieve fts: squat fts_squat: partial=4 full=10 autocreate: Trash autocreate2: Drafts autocreate3: Spam autocreate4: Sent autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Spam autosubscribe4: Sent dict: expire: db:/var/db/dovecot/expire.db

[Dovecot] RFC: grouped (f)sync
by Attila Nagy 06 Jan '11

06 Jan '11

Hello, Currently Dovecot (and any other application, which cares about e-mail delivery) does at least one fsync per mail delivery. Given that hard disk drives have a very limited IOPS, this effectively limits the maximum mail delivery performance to a very low value, under utilizing the available storage IO capacity. Calculating with an average mail size of 50 kB and an average consumer HDD with 120 IOPS, the theoretical mail delivery performance will be 50 kB*120 IOPS=5.85 MBps. But if we could write 500 kB with every transaction, the delivery speed would be nearly 10 times as well. Dovecot have two process models: separate processes for each client connection and an async in-process multiplexing method. This works for each one, albeit the timing is somewhat different. So here's the idea: instead of fsyncing immediately in the LDA (lmtpd) every time when the client says "\r\n.\r\n" after the DATA phase, let's introduce a user settable timer (let's call that sync_delay from now on) and only sync in every sync_delay seconds. This would introduce an up to sync_delay seconds delay in lmtpd returning "250 Ok" to the client, but that's generally not a problem, because in high traffic setups there is a great amount of concurrency, so you could use a lot of client connections easily. Take an example setting of sync_delay = 100 ms. With this, 10 syncs would happen in every second from Dovecot LDA processes, meaning if a client connects in t=0 it will immediately got the response 250, if a client connects in t=0.05, it will get the response in 50 ms (in an ideal world, where syncing does not take time), and the committed blocks could accumulate for a maximum of 100 ms. In a busy system (where this setting would make sense), it means it would be possible to write more data with less IOPS needed. I can see two problems: 1. there is no call for committing a lot of file descriptors in one transaction, so instead of fsync() for each of the modified FDs, a sync() would be needed. sync() writes all buffers to stable storage, which is bad if you have a mixed workload, where there are a lot of non-fsynced data, or other heavy fsync users. But modern file systems, like ZFS will write those back too, so there an fsync(fd) is -AFAIK- mostly equivalent with a sync(pool on which fd is). sync() of course is system wide, so if you have other file systems, those will be synced as well. (this setting isn't for everybody) 2. in a multiprocess environment this would need coordination, so instead of doing fsyncs in distinct processes, there would be one process needed, which does the sync and returns OK for the others, so they can notify the client about the commit to the stable storage. Any opinions on this?

[Dovecot] virtual user problems
by G.Nau 06 Jan '11

06 Jan '11

dovecot 2.0.8 with postfix; transfer postfix -> dovecot by lmtp is fine Now i have to redirect a couple of virtual email names (like admin(a)mydomain.com, postmaster@, webmaster@, info@, sales@ ...) to a single user postbox named xxx@mydomain. As I use mysql for the auth-sql, it's returning userhome /home/<name>/maildir for all sql requests to <name>=admin, postmaster etc. I also verified that "doveadm user info" is returning the maildir/home: /home/xxx/maildir So I assumed, that all mails to admin, postmaster etc. are transfered to user xxx mailbox. But it isn't. Dovecot is creating the maildirs /home/admin/maildir, /home/info/maildir and so on. What do I miss here to get that virtual users mapped to the correct user xxx? Regards Birte

[Dovecot] case (non-)sensitivity for folder names
by Phil Howard 06 Jan '11

06 Jan '11

Is IMAP supposed to be case sensitive or case in-sensitive? It seemed it would be case sensitive because I've had different cases of folders. But today I found I had two folders "Spam" and "spam", with directories ".INBOX.Spam" and ".INBOX.spam" on the server. Messages existed in each directory on the server and they were different. The messages could be read from Evolution. However, the list of messages had info mixed up between the folders. I then selected all messages in one of the folders and trashed them (click on trash icon). Messages disappeared in BOTH folders. On the server, after a couple minutes delay, messages in BOTH directories were flagged "T". That doesn't seem right. But I don't know enough about what IMAP is supposed to do, or on which end the names of folders get remapped into directory names, to even guess which is messed up here. I do know Evolution keeps a track of what it thinks the folder has, because in the past I have just "rm -fr" on a folder directory and Evolution still showed each message in its list, although it could not access them. Anyone know what's the deal with that? Unfortunately, there seems to be no operation in Evolution to tell it to discard its own cache. I'm also wondering if life would be any better if I used Thunderbird. -- sHiFt HaPpEnS!
