[Dovecot] Cannot fill the maildir with mails
by Peter Selter 30 Jan '07

30 Jan '07

Hello! I have installed Dovecot yesterday as a simple connection between a local mailbox and Novell Evolution. I have set up a POP3 service that I can succesfully connect to. I chose the Maildir structure but the whole box is empty. When I try "echo ´test´ | mail -s ´test´ user42" it doesn´t reach the mailbox. What can I do? I could also try the mbox format but Evolution has problems connection to an mbox file, it just says "loading..." and nothing happens. Any help would be appreciated :-) regards, Peter ____________ Virus checked by G DATA AntiVirusKit

[Dovecot] popa3d migration
by FiL ＠ Kpoxa 30 Jan '07

30 Jan '07

Hello, I'm sure there is no good answer to my question, but it doesn't take much to ask, so I will. I am about to migrate my current Dovecot IMAP + Popa3d mailbox server to Maildir. I need to keep both protocols (IMAP and POP3) and will be switching to Dovecot on both. The question is simple - is there any way to keep POP3 UIDs through migration, so people won't get duplicates in their inboxes. Second question is not that important but if somebody has a good answer it will be really nice - is there any way to keep IMAP UIDs? With IMAP it won't create dups, but loosing (changing) UIDs will create extra load on the server. I know, this is more about mailbox->Maildir conversion, not dovecot, but this is the only place I can ask this question P.S. am running dovecot on linux FC5 right now, but will be upgrading to FC6 / dovecot 1.0 release at the time of migration. Won't do it before 1.0 final comes out Thank you, FiL

[Dovecot] dirsize quotas crashing 1.0.rc19
by Dean Brooks 30 Jan '07

30 Jan '07

Hi, I've been trying to get dirsize quotas to work properly with 1.0rc19 and Dovecot consistently crashes when attempting to do file copies once a user is over quota. Dovecot works fine for us for regular mbox based IMAP, but as soon as I add the following two entries in their respective locations in dovecot.conf: mail_plugins = quota imap_quota (in the imap{} section) quota = dirsize:storage=2000 (in the plugin{} section) If a user goes over quota, and they attempt to copy a file to a folder via IMAP, all I get is this: dovecot: [ID 684838 mail.error] child 20868 (imap) killed with signal 10 Is anyone successfully using dirsize:storage quotas with 1.0rc19? If so, can someone else verify if they see crashes like this? As soon as I remove the quota plugin, the crashes go away and all is good, so there's obviously some sort of problem in the quota plugin. Regards, Dean Brooks dean(a)iglou.com

Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by James Garrison 29 Jan '07

29 Jan '07

I reported this against rc7 and rc8, and still see it occasionally. (I'm running the rc8 that comes with Fedora 5). It is always associated with this message in dovecot.log: dovecot: Oct 23 19:26:17 Error: POP3(user(a)domain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 > 4, seq=2, idx_msgs=5) Once this happens, dovecot will refuse to clear out the mbox file when the user retrieves email via POP. Each time the user logs in to retrieve mail s/he gets everything in the mbox, which continues to grow. The only fix I've been able to find is to manually delete the mbox file. I'm using postfix as the MTA. -- James Garrison Athens Group, Inc. mailto:jhg@athensgroup.com 5608 Parkcrest Dr http://www.athensgroup.com Austin, TX 78731 SKYPE callto:jhg-athensgroup (512) 345-0600 x150 PGP Key ID: 0x22E8DA2A

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 29 Jan '07

29 Jan '07

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have since received several reports of dovecot erroneously retrieving older messages as new mail. I've seen this myself intermittently on KMail, and users have reported it on Thunderbird, Squirrelmail, and Outlook. I see some things in the archives that suggest that this was a problem in older 1.0 release candidates, but hadn't experienced the problem myself until just now. Has anyone else seen this problem? Regards, - Brian

[Dovecot] Best small server config
by - 29 Jan '07

29 Jan '07

Hi, Busy with dovecot on a linux server with not very much RAM in it (512 MB max total). On this server dovecot will only handle about 12 users, with never more than 3 IMAP webmail users at a time, and a maximum of 2 POP3 users at a time using it. I'm going all secure later on, but first I would like your opinion on what configuration best to use with, say, max 5 users busy at one time, and have it use as little RAM and CPU as possible. (Same machine is also running httpd, squirrelmail, php5, postfix, clamd, clamsmtpd, sshd.) Here's my /etc/dovecot.conf now: # protocols = imap pop3 imap_listen = * pop3_listen = my.servers.ip.address (hidden for this list) ssl_cert_file = /etc/ssl/certs/imapd.pem ssl_key_file = /etc/ssl/private/imapd.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat ssl_parameters_regenerate = 320 login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/home/%u/Maildir mailbox_idle_check_interval = 40 mail_full_filesystem_access = yes login_user = dovecot login_process_size = 64 login_process_per_connection = no login_processes_count = 4 login_max_processes_count = 4 login_max_logging_users = 5 max_mail_processes = 140 imap_process_size = 192 pop3_process_size = 64 first_valid_uid = 500 last_valid_uid = 520 mail_cache_fields = MessagePart mbox_locks = fcntl mbox_read_dotlock = no mbox_lock_timeout = 380 auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_process_size = 64 auth_user = root # Any insight or advice welcomed!

[Dovecot] Benchmarking
by Timo Sirainen 29 Jan '07

29 Jan '07

I wasted too much time today doing this, but they do show a few interesting things: 1) mmap_disable=yes is faster than mmap_disable=no. I didn't expect this. I'm not yet sure why this is, but possibly because then it updates the mail index by reading the changes from dovecot.index.log, instead of reopening and re-mmaping dovecot.index. At least that's the biggest difference between them. 2) Dovecot is faster than Cyrus, at least in test. I didn't really expect this either, because with maildir Dovecot has to do extra rename() calls for all flag changes. I'm guessing it's expunges that are slowing Cyrus down the most (that causes it to rewrite its cache file). 3) fsync_disable=yes + mmap_disable=yes almost doubles the performance with 1 client, and over quadruples the performance with 10 clients. Why fsync_disable=yes + mmap_disable=no doesn't give that big of a performance difference? I've no idea. This is anyway such a large performance increment that I'll probably go and backport this setting to v1.0 too :) 4) Dovecot's mbox code kicks maildir's ass. 5) dbox is surprisingly slow. I'll have to find out why. I don't think it should be that slow. 6) Courier.. Well, it probably doesn't come as a shock that Dovecot is almost twice as fast. Note that Courier doesn't call fsync(), so it can't be compared to Dovecot's fsync_disable=no numbers or to Cyrus. Oh, one other difference between Courier and others was that it didn't support LITERAL+ extension, so it maybe could have done a bit less appends than others. 7) CVS HEAD and branch_1_0 don't seem to have that big of a performance difference. All the tests were done using my IMAP tester: http://dovecot.org/tools/imaptest.c The mailbox data that was being appended was Dovecot's mailing list: http://dovecot.org/archives/dovecot.mbox The linefeeds were converted to CR+LF. However, for the Dovecot CVS HEAD runs the mails contained also those extra X-UID, Status, etc. headers which I had to remove before Cyrus would accept them (the lines didn't contain CRs). So CVS HEAD was actually doing a bit more work than the others.

[Dovecot] POP3 logging in wrong timezone
by - 27 Jan '07

27 Jan '07

I have dovecot running on a CentOS 4.4 server, and it is logging IMAP entries just fine, in the right timezone (GMT+1), which the server itself is running on (CET), but pop3 is being logged in GMT 0, so 1 hour too early. pop3 log-entries are at the right position in the maillog, but with the wrong time next to it. Now I've read some messages in this list about this bug (or feature), but have no clue as to how to solve it. Anyone? Thanks in advance, Ben

[Dovecot] Advice, Converting a Live/Production server.
by Michael Dilworth 26 Jan '07

26 Jan '07

I want to mess with a live server. (a Bad thing). I have googled until my eyes boogled, wiki'ed until my fingers are wonked, have read as much as I can read, however I'm left with a few questions/worries. Issue: I am currently running Dovecot as a pop3 server with standard /var/mail mbox's I would like to run a mixed Imap/Pop3 server with ~/maildir inbox's The thread http://www.dovecot.org/list/dovecot/2006-February/011304.html is fairly close to what I want to do, but I would like to go ahead and convert to maildir. (Mixed pop3/imap access for each user) I don't have a system to test, "I used have one but it's now the production server... PW/Disk failed, thank G-D(s) for rsync/backups". Setup: procmail, dovecot 1.0 beta 8.2 (fc5), squirrelmail. all users use outlook (2000,2003) or outlook express (random versions) (^^^^ not my choice, I just have to deal with it {and use it} ^^^^^) the majority of users will continue to use pop3, however some would like to convert to imap and have all mail stored on the server. Questions: /etc/procmailrc? just set default to ~/maildir? do I need to define "INBOX"? aka $MAILDIR=~/maildir/, $ORGMAIL=~/maildir/, $DEFAULT=~/maildir/ Same as above, what about new/cur should I set up a /etc/skel? close to above, if I create rules, for spam, etc. do I need to worry about cur/new. close to above, what about Sent Items, Drafts etc... for imap users, I do understand that client rules would likely be needed to store sent items. conversion, anything to look for? mb2md seems to work, but some users have "don't delete from server set", will they get dups? (I can live with this) archiving, can I (or a script) mess with the files in the maildir? aka keep the number of files/messages less than 16k for the outlook users. Bugs, should I cool my heals, and wait for rc16 or 1.0 final? I am currently running problem free, and I do hate to mess with something which is not busted. TIA Michael.

[Dovecot] Dovecot POP3 fails to chdir under FC6
by James A. McDonald 26 Jan '07

26 Jan '07

I started the Dovecot POP3 server under Fedora Core 6 (rpm dovecot-1.0-1.1.rc15.fc6), but some users couldn't connect, with /var/log/maillog show the message Jan 24 13:20:00 mmace dovecot: chdir(/branch/home/mmace) failed with uid 205: Permission denied Jan 24 13:20:00 mmace dovecot: child 18792 (pop3) returned error 89 (I had already edited first_valid_UID in /etc/dovecot.conf to allow UID's >= 200.) However, only users who had their home directory under /branch/home couldn't connect. Users with homedirs under /home connected via POP3 just fine. I found out POP3 connection failures also logged an error to /etc/messages: Jan 24 13:20:00 mmace kernel: audit(1169662800.479:160): avc: denied { search } for pid=18792 comm="dovecot" name="/" dev=sda3 ino=2 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:mnt_t:s0 tclass=dir So, selinux was the culprit. My home directories had the right selinux security context, but the root of the disk holding those home directories (/branch is a separate disk drive) had a security context (system_u:object_r:mnt_t) that Fedora's selinux rules for dovecot did not allow. I changed the context of /branch to system_u:object_r:usr_t, and dovecot POP3 access worked for all users.

[Dovecot] X-UID gaps cause Dovecot/IMAP to hang
by Benjamin Howell 25 Jan '07

25 Jan '07

Hi, When the Dovecot 1.0.rc19 IMAP server encounters X-UID headers with gaps in them, it hangs indefinitely. I've attached a sample mailbox (in mbox format) which repeatably exhibits this behavior. The mbox contains only three messages with the following X-UIDs in order: 774, 785, 787. If I remove the X-UID headers from each message, Dovecot handles the mailbox without any problems. UW-IMAP is able to handle the sample mbox _with_ X-UID headers. A full backtrace is also included. When Dovecot hangs, it appears to continually lock and unlock the mailbox. I'm using dotlocking so a mailbox.lock file appears and disappears constantly. I have to kill the process to log back in. I'm not familiar enough with Dovecot to offer a patch, but if anybody feels they can fix this or needs more information, please let me know. Regards, Benjamin Howell bhowell(a)iglou.com

[Dovecot] rc18->rc19: read/unread/reply flags broken
by Jeff A. Earickson 25 Jan '07

25 Jan '07

Timo, This might be a bit vague, but I have noticed that rc19 seems to have broken the read/unread/reply flags in imap. My officemate has had problems with messages that are read and marked as read then mysteriously get remarked as unread the next time email is checked. I've had problems where I reply to a message and it does not get marked as "answered". We didn't see this with rc18 and earlier. My setup: Solaris 10, sparc, T2000 system. rc19 (now back to rc18), using mbox format. system mailbox is NFS mounted from another Sun Solaris 10 system, homedirs and dovcot cache files are on local zfs filesystems.

Re: [Dovecot] X-UID: 4085788205 != 2147483647

On 24.1.2007, at 2.49, Stephen Gowing wrote: > It *is* possible to force a large X-UID, if the user has an empty > inbox > (tested on rc15). Yes, but only if it's the very first message for the user. Afterwards even if user expunges all the messages, there are two things that prevent this from being possible: index files and the UW-IMAP style "FOLDER INTERNAL DATA" message. You could also prevent this completely by stripping the X-UID header in your SMTP server or LDA. For example Dovecot LDA strips all the Dovecot's internal metadata headers. I guess the UID renumbering could be done some day, but for now I think it's just way too much trouble with not that much benefits.

[Dovecot] dovecot LDA 'deliver' and aliases
by Michael Pulk 25 Jan '07

25 Jan '07

Dovecot LDA (deliver) aliases question. I have a multiple virtual domain setup using sendmail, username/domain, password, home directory all stored in mysql,Set-UID/GID for dovecot 'deliver' setup as referenced in Dovecot LDA wiki. Delivery, and POP/IMAP work just fine, serving a mail store in /home/vmail/domain/username type of setup. My problem comes from what may be a misunderstanding on my part on how to setup aliases for some virtual users. I have the mailer specification for dovecot defined, and my mailertable and (access) tables setup for each domain, with an entry like this for each domain in mailertable: domain.com dovecot:dovecot and since I also function as SMTP relay for each customer, I also have an entry in in access domain.com RELAY and the tables are made with hash... this all appears to work just fine, except when I want to alias a certian email address. Lets say that I have one email in the domain that needs to be forwarded to another remote account (on another server), I would normally accomplish this with an entry in virtusertable something like this: sales(a)domain.com <mailto:sales@domain.com> user(a)otherdomain.com <mailto:user@otherdomain.com> but when using dovecots' deliver as the LDA specified for domain.com in mailertable, this appears to be ignored, with the email being returned undeliverable (if sales(a)domain.com <mailto:sales@domain.com> doesn't exist), or being delivered to sales(a)domain.com <mailto:sales@domain.com> (if the account exists in the mysql table). I have also tried creating the account, and placing a .forward file in the appropriate /home/vmail/domain/user directory, but this also appears to be ignored. Does anyone have some advice on how to implement such an ability? I am running dovecot-1.0.rc17, sendmail-8.13.1-3.RHEL4.5, mysql-4.1.20-1.RHEL4.1 on Centos 4.4 Sincerely Michael P.

[Dovecot] NEWBIE: configuring all virtual users...
by AJ Weber 24 Jan '07

24 Jan '07

OK, I'm trying to filter-through all the different WiKi and docs about how to configure all virtual users. Now, there's only going to be a few, and it's a secure env, so I'm going to try and configure a custom passwd file (or whatever trimmed-down version I can do), basically to do usernames, passwords, and MBOX dirs. I'm only planning on serving POP3 mail to my clients. I have a location to create MBOX files -- it will be in a specific directory, with sub-dirs for each user; sort of a /home/VU/%u/mbox . I'm really confused as to what add'l info I need to include like "INDEX" and "INBOX" on the mail_location info. Does anyone have any info and/or examples on how to configure my .conf file and create a minimal passwd file for these virtual users? Thanks in advance, AJ
