[Dovecot] kmail-error: can't upload folder (imap-account on dovecot-server)
by cool.chris65＠web.de 17 Oct '10

17 Oct '10

Hello, I've some trouble with my kmail (Version 1.13.5 / KDE 4.5.1, Kubuntu 10.04 and a dovecot-imap-server on debian etch (dovecot 1.0.rc15-2etch5). Everytime I try to create a folder under my imap-inbox, I get an error like "can't upload folder...", but after this message I can see a new folder under my inbox-folder, but I can't use it ... With a thundermail-client I can create a subfolder without any erro and I can use it r (but only first level). My conf: # /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot.log disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: Herzlich Willkommen, %u. mail_location: mbox:~/mail imap_client_workarounds: outlook-idle tb-extra-mailbox-sep auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd The reason for using debian etch and dovecot 1.0 is the hardware: it's running on a Fritzbox-Router, and there is actual a littlebit trouble with lenny (often crashing, reboots of the whole box etc.) I hope, someone can help me ... Thanx and greetz, Christoph -- GPG-Fingerprint: 171A 6F66 52E5 A6CE D664 2427 832F E711 7442 8261

[Dovecot] Quota, Postgres + Postfixadmin
by Roman 17 Oct '10

17 Oct '10

Hi everybody, i am currently testing dovecot-1.2.9 together with postfix, postgres and postfixadmin. After setting up the basics, i wanted to get the quotas working... So i edited the dovecot.conf: mail_plugins = quota imap_quota mail_plugins = sieve quota quotadict = pgsql:/etc/dovecot/dovecot-dict-quota.conf quota = dict:user::proxy::quotadict and dovecot-dict-quota.conf: connect = host=localhost dbname=postfix user=yyy password=xxx map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } After moving some mail on and off the account and finally cleaning out any mail (verified via console) quota2 looks like this: username bytes messages test(a)testdomain.de -1009339 -1 So it seems to me its calculating sth. wrong? Or am i doing sth. wrong? greetings, Roman -- printk(KERN_ERR "happy meal: Transceiver and a coke please."); linux-2.6.6/drivers/net/sunhme.c

[Dovecot] Dovecot 2.0.5 and BSDI 4.3 again

[Dovecot] Convert plugin
by Egbert Jan van den Bussche 15 Oct '10

15 Oct '10

Hi, I'm trying to get old mail from /var/mail/<user>, where <user> is the (sometimes) huge mailfile, not a directory, converted to the maildir INBOX in ~/Maildir. Users have no ~/mail directory; they were supposed to use pop3 only. I'm trying the example from the wiki: plugin { convert_mail = mbox:~/mail:INBOX=/var/mail/%n } but have still not succeded. I tried /var/mail/<user> where <user> is a file and /var/mail/<user>/<user> where user is first a diredtory en the second <user> a file. I also used the filename 'inbox', since the logging suggested that to me. Other logging seems to indicate that the right maildir++ info is composed. I'm in vor any advise!

[Dovecot] Weird glitches with public folders - Dovecot not using per-user INDEX?
by Kádár Tamás (KTamas) 15 Oct '10

15 Oct '10

Hi I have this public folder: namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } Access is controlled by ACLs, everyone who has access is 'lrwstipek' except for some people who also have 'xa' privileges. As you can see it is set to put its index to the user's Maildir so they can have per-user \Seen flags. And that is the case -- most of the time anyway. But for some folders, and I can't figure out why those, they just don't work: if someone sets a message read it immediately becomes read for everyone else, too, and vice versa if someone marks a message unread, it becomes unread everywhere. Further investigation shows that in these problematic folders, indeed all users directly manipulate the flag of the email (i.e. X marks email Z read, ",S" appears immediatelly in the filename). Anyone knows what I'm doing wrong? I can't seem to find anything different with these problematic folders, ACLs look right etc. Thanks in advance, Tamas

[Dovecot] Custom Flags
by qmail＠top-consulting.net 15 Oct '10

15 Oct '10

I have modified my delivery agent to deposit files in my Maildir already containing custom flags. For example, x is appended for files that are sent from local users, y is for e-mails from Contacts and z is for e-mails from Whitelisted sources. A file will thus be delivered in the Maildir and be called something like: filename:2,yz Also in the Maildir I created a file called dovecot-keywords and have added these 3 flags in there as so: #cat dovecot-keywords 23 Local 24 InContacts 25 Whitelisted I went ahead and erased all the dovecot-uid* dovecot.index* files but Dovecot won't recognize the flags - furthermore, it labels z as 'unknown-25'! - for both old messages or new messages. Here is a bit of IMAP conversation: a02 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted ) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted \*)] Flags permitted. a03 SEARCH KEYWORD Whitelisted * SEARCH * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted \*)] Flags permitted. a03 OK Search completed (0.004 secs). a04 SEARCH KEYWORD unknown-25 * SEARCH a04 OK Search completed (0.004 secs). I know for sure there are files with the z letter in their name in the Inbox. What is going wrong ?

[Dovecot] Limit access to dovecot by domains?
by Jobst Schmalenbach 15 Oct '10

15 Oct '10

Hi. Is there any way to limit access to dovecot by domains. I only need to give access to a well known set of domains, all from Australia and all networks are known and used either from people at home or mobile access (phones, laptops etc). iptables is not possible as e.g. OPTUS does not give away all of the networks mobile phones are connected to. I know some, but not all. It would be much nicer and easier to allow optusnet.com.au bigpond.com.au tpg.com.au and I have given 100% of our users access. I know there is an extra field called "allow_nets", I tried this and failed. I did a search and found that this only works with SQL? Maybe I could include a script that would check the reverse DNS record of a connected IP and then I could filter?????

The problem is when doing doveadm stuff. I do not know ldap (learning as I go). I need to set the uid/guid to vmail (500 in this case if vmail can't be used). Any help would be greatly appreciated. I do not have sfu or rfc2xxx enabled as this requires changing things with Samba 4 that I would rather avoid at the moment.

[Dovecot] Master user sees empty folder list
by interfaSys sàrl 15 Oct '10

15 Oct '10

Hello, I'm having a "path" problem with master users. When logged on as a master user, I can't see the user's folders. I'm trying to use system users as master users, so I'm using something like this: # Master password auth_master_user_separator = * passdb { driver = passwd master = yes pass = yes } # System users passdb { driver = passwd } # Virtualusers users passdb { driver = passwd-file args = username_format=%n /etc/virtual/%d/passwd } mail_location = mdbox:~/mdbox System and virtual users see their folders fine, including the shared namespaces, but as a master user, I see an empty mailbox. I've turned on debugging and watched things like root= and fs= and they're normal. Permissions should be OK since the system user has the same uid:gid as the virtual user. What could it be? Cheers, Olivier

[Dovecot] dovecot-lda segfaults (debug)

[Dovecot] "doveadm mailbox create" oddities
by Andre 15 Oct '10

15 Oct '10

Hi to all! I’m trying to understand the usage of "doveadm mailbox create”. If I do, as root: # doveadm mailbox create -u __public__ sys/test doveadm(__public__): Error: Can't create mailbox sys/test: Permission denied but if I do: # doveadm mailbox create -u __public__ test every thing is OK. “sys" is a shared maildir folder, that is visible in the client as "#Public/sys”. __public__ is the user that owns Public folders, here is the complete details: userdb: __public__ uid : 10002 gid : 8 home : /var/mail/domainname/__public__ mail : maildir:~/maildir:INBOX=~/maildir/INBOX:LAYOUT=fs:INDEX=~/indexes/ Do I have to add root with proper permissions to ACL? TIA Andre

[Dovecot] Dovecot chgrp actions on new files/folders
by David Ford 14 Oct '10

14 Oct '10

Timo, I did further study of the user/group permissions. Applying the below patch will make no difference to virtually everyone out there. Those that have default uid/gid ownership won't see any change as the gid already matches so the fchown() action won't be attempted. Those that have sgid will still see the normal expected fchown() enforced by the kernel which becomes a duplicated action by dovecot. In the last case, those with an unknown 3rd party gid were used to seeing fchown() failures and those will now go away. It is only this third group that will see anything change as all other cases are already handled. Anyone who wishes to create new files with another group ID should make their directories sgid or stgid as per normal filesystem ACL semantics. The original net effect of this only turns on an fchown() that will fail and emit numerous error messages. This patch fixes that. Technically the fchown is unneccessary extra code already since any directory that is sgid or stgid will have ownership enforced by the kernel already. I simply made it #if 0 below, the correct patch would be to delete the extraneous block. --- src/lib-storage/mailbox-list.c.orig 2010-09-14 11:03:18.000000000 -0400 +++ src/lib-storage/mailbox-list.c 2010-10-08 13:02:54.000000000 -0400 @@ -450,7 +450,7 @@ } if (S_ISDIR(st.st_mode) && (st.st_mode & S_ISGID) != 0) { - /* directory's GID is used automatically for new + /* directory is sgid, so GID is used automatically for new files */ *gid_r = (gid_t)-1; } else if ((st.st_mode & 0070) >> 3 == (st.st_mode & 0007)) { @@ -460,9 +460,13 @@ } else if (getegid() == st.st_gid) { /* using our own gid, no need to change it */ *gid_r = (gid_t)-1; - } else { + } +#if 0 +#warning this code makes dovecot attempt to chgrp files to wrong ownership + else { *gid_r = st.st_gid; } +#endif } if (name == NULL) {

[Dovecot] lazy_expunge and moving messages
by Lutz Preßler 14 Oct '10

14 Oct '10

Hello, testing the lazy_expunge plugin (with 2.0.5), I realized the following effect, which users may not expect/understand: As moving messages from one folder to another has to be done by clients with the IMAP command sequence COPY STORE EXPUNGE, every moved message is also put into the "shadow folder" of the source folder. Maybe it's possible to extend the plugin to optionally hook into the COPY operation, remember it somewhere with the message (simply as special/ configurable IMAP flag?), and then really expunge messages with this flag set. What do you think? I haven't looked into the plugin interface yet. Of course, if a user manually copies a message and deletes the source message later (maybe having the copy deleted inbetween...), the consequence may not be expected either...

[Dovecot] limits to serve sure a number of users
by Schmidt 14 Oct '10

14 Oct '10

Hi, lets say dovcot should serve 1000 user (only imaps) without rejecting a users connection because of to short resources. With version 1.x I had to increase login_max_processes_count = ... With 2.x I'm not sure which parameters I have to set. So Thunderbird 3.x has a default value of 5 connections to cache. "dovadm who" shows quite often 5 connections: userx 5 imap (11154 11152 11158 11156 11150) ... So dovecot has to be configured for 5000 connections/imap-login's? Within 10-master.conf these defaults are shown #default_process_limit = 100 #default_client_limit = 1000 Is it right process_limit is not generally a problem because oldest imap-login process(?) will be closed? (With this expected number of users this value should be increased too.) But what about client_limit? Does it has to be increased to 5000? (There have been some hints by Timo concerning "doveconf -a service" to see how limits will be used for different services.) Any advices? thanks -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] userdb syntax
by suzuki 14 Oct '10

14 Oct '10

Hello, I have a question about userdb lookup when using expire-tool. Dovecot version 1.2.15 In dovecot.conf, mail_location = maildir:/var/mail/%u:INDEX=/var/indexes/%u I run dovecot expire-tool, target user's directory becomes executing user's one. According to wiki, userdb setting overrides mail_location. userdb passwd { mail=maildir:/var/mail/%u:INDEX=/var/indexes/%u } With this setting, it seems working. But, there are no examples with ":INDEX=.." setting. Is this syntax right? Regards

[Dovecot] Problem with dovecot-acl was not solved
by dss 14 Oct '10

14 Oct '10

Problems with acl in dovecot-1.2.15 was not solved! See my configs below. And I see the new bug - still something wrong with configs: cat dovecot-acl: user=t1 lrwsti #user=oper-olegs lrwsti #user=oper-antona lrwsti user=operdss lr #user=operdss lrwsti User t1 can't create subfolers in inbox. He can only create subfolders in the first levels: Inbox test3 test4 Outbox Sent Trash Test1 - test folder created by t1 user Folders test3 and test4 can't be deleted by t1 - why? Owner of the test3 and test4 - annother user, but but with group rights everething is fine. User operdss also can create folders in the same level with such permissions.

Some of our users need to use the same Mailbox with all folders: Inbox (with subfolders), Outbox, Send and Deleted, (some users need in full righs, some - readonly) so I choosed Symlinking mailboxes and tried to use dovecot-acl file. cat dovecot-acl: user=t1 lrwsti user=operolegs lrwsti user=operantona lrwsti user=operdss lr User operdss have lrwsti rights in this shared mailbox unstead of lr! But if I comment out other users in the dovecot-acl: #user=t1 lrwsti #user=operolegs lrwsti #user=operantona lrwsti user=operdss lr User operdss have lr rights. Whats wrong? It seems, that dovecot-acl is working only for one user and for one line in config. How can I fix it? === Here is my configs. imap:/usr/local/dovecot# /usr/local/dovecot/sbin/dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.6 log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /usr/local/dovecot-1.2.15/var/run/dovecot/login login_executable: /usr/local/dovecot-1.2.15/libexec/dovecot/imap-login mail_privileged_group: mail mail_plugins: acl imap_acl auth default: debug: yes passdb: driver: pam userdb: driver: passwd ---- imap:~# ls -l /home/t1/Maildir lrwxrwxrwx 1 root root 21 2010-09-22 16:03 /home/t1/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operolegs/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operolegs/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operantona/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operantona/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operdss/Maildir lrwxrwxrwx 1 root root 16 2010-09-28 16:32 /home/operdss/Maildir -> /home/t1/Maildir --- imap:/home/t1/Maildir# ls -l total 112 drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 cur -rw-rw---- 1 t1 mshare 99 2010-09-29 15:56 dovecot-acl -rw-rw---- 1 operdss mshare 312 2010-09-29 16:43 dovecot-acl-list -rw-rw---- 1 operolegs mshare 1144 2010-09-24 12:16 dovecot.index -rw-rw---- 1 t1 mshare 41984 2010-09-28 16:39 dovecot.index.cache -rw-rw---- 1 t1 mshare 25068 2010-09-28 16:38 dovecot.index.log -rw-rw---- 1 operantona mshare 17 2010-09-23 16:41 dovecot-keywords -rw-rw---- 1 operantona mshare 1941 2010-09-27 10:46 dovecot-uidlist -rw-rw---- 1 t1 mshare 8 2010-09-29 16:43 dovecot-uidvalidity -rw-rw---- 1 t1 mshare 0 2010-09-22 10:54 dovecot-uidvalidity.4c99a82f drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 new -rw-rw---- 1 operdss mshare 327 2010-09-29 16:43 subscriptions drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 tmp ----- dovecot packages - dovecot-1.2.15 --- Linux: Debian Lenny up2date

[Dovecot] Dovecot 2.0 lock upgrade assertion failure
by Ryan Murray 14 Oct '10

14 Oct '10

Hi! I've now seen this assertion failure from lmtp (most frequent), pop3 (next frequent), and imap (rarely). It didn't start happening until the number of accounts on the server was increased into the 10k-25k range. It happens when index->file_lock is a read lock and mail_index_lock is called asking for a write lock. Dovecot 2.x dies at the assertion on line 62 of mail-index-lock.c If that assertion were removed, it would likely die at the assertion on line 80. Looking at the mail-index-lock.c from dovecot 1.2.15, it looks like the 1.2 series would enter the else case of the "kind of kludgy" block, and end up calling file_lock_try_update(), which seems like what needs to happen. Dovecot 2.x only does a file_lock_try_update() when unlocking, to demote a write lock to a read lock (according to grep). # 2.0.5 (6ea01abfaea9): /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.6 x86_64

[Dovecot] managesieve fileinto folder with international characters
by Edward Carraro 14 Oct '10

14 Oct '10

I have a folder created in dovecot entered by the user as "ññoéé" On the file system it appears as "&APEA8Q-o&AOkA6Q-" (mUTF7) When creating a sieve rule, to file into the folder ññoéé, I am converting the name from UTF8 into UTF7, the rule becomes require ["fileinto"]; if header :contains ["From"] "user(a)domain.com" { fileinto "&APEA8Q-o&AOkA6Q-"; } however when executed, a sieve log is generated saying: failed to store into mailbox '&APEA8Q-o&AOkA6Q-' (&-APEA8Q-o&-AOkA6Q-): Mailbox doesn't exist: &-APEA8Q-o&-AOkA6Q-. If I directly modify the sieve file and place the actual utf8 version of the folder in it require ["fileinto"]; if header :contains ["From"] "user(a)domain.com" { fileinto "ññoéé"; } I get the following error: main_script: line 1: error: folder name specified for fileinto command is not utf-8: ññoéé.

[Dovecot] Outlook FLAGS bug
by qmail＠top-consulting.net 14 Oct '10

14 Oct '10

I believe I have uncovered an Outlook bug. I've searched on the Internet a bit but I didn't find much on this particular topic. Basically it seems that Outlook (I'm using 2007) is overwriting message flags at least when replying to messages. I have seen the following behavior in the dovecot logs, first for only viewing a message, second when replying to a message. urfh UID STORE 65998 +FLAGS (\Seen) 3fxj IDLE DONE ejm4 UID STORE 65998 FLAGS (\Seen \Answered) The second STORE effectively wipes out any other flags on the message and replaces them with \Seen & \Answered I tried the same operation in Thunderbird and it performs properly. Anyone else encountered this bug ? Anyone knows if it's fixed in 2010 ?

[Dovecot] Error on mailbox file
by augustocasagrande＠gmail.com 14 Oct '10

14 Oct '10

Hi! I'm running Postfix 2.2.9 as MTA. I have several mail clients , such as Outlook 2000/xp/2007. The clients comunicate to the MTA using pop3/smtp protocols. I have also installed Webmail Squirrel for the internet users. Squirrel needs an Imap server, so i have utilized Dovecot 1.2.6. To authenticate users , i use pam_winbbind to validate users to my NT domain. Here is my problem : Today i checked my /var/log/mail log and this took my attention : Sep 29 08:25:07 host1 dovecot: imap-login: Login: user=<USER>, method=PLAIN, rip=172.20.22.12, lip=172.20.22.14 Sep 29 08:25:07 host1 dovecot: IMAP(user): mail_location: mbox: mkdir(/home/NT-DOMAIN/user/mail) failed: Permission denied (euid=10188(user) egid=10001(domain users) missing +w perm: /home) Sep 29 08:25:07 host1 dovecot: IMAP(user): Fatal: Namespace initialization failed Here , i assume the user put his user name in CAPS (USER), and that i generating an error. Then Dovecot tries to create the directory /home/NT-DOMAIN/user/mail. In my dovecot.conf file , i have : mail_location = mbox:~/mail:INBOX=/var/mail/%u Now , the log continues : Sep 29 08:25:18 host1 dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=172.20.22.12, lip=172.20.22.14 Sep 29 08:25:18 host1 dovecot: IMAP(user): mail_location: mbox: mkdir(/home/NT-DOMAIN/user/mail) failed: Permission denied (euid=10188(user) egid=10001(domain users) missing +w perm: /home) Sep 29 08:25:18 host1 dovecot: IMAP(user): Fatal: Namespace initialization failed Here the user re-enters the user, now correctly, but the problem persists . Finally , a could see this new log entry : Sep 29 10:50:43 host1 postfix/local[19663]: 50B98441E0: to=<user(a)domain.com>, orig_to=<user(a)domain.com>, relay=local, delay=0, status=bounced (cannot access mailbox /var/mail/user for user user. cannot open file: Permission denied) Here some user tries to send an email to this user , and a permission denied error occurs. Watching the permissions on the file : -rw------- 1 user users 1499655 2010-09-29 02:18 /var/mail/user Maybe some Dovecot process is blocking the file access ? List of Dovecot process: ps ax | grep dovecot 25997 ? Ss 0:07 /usr/sbin/dovecot 15399 ? S 0:02 dovecot-auth 20614 ? S 0:00 dovecot-auth -w How can i fix this issue? Thank you very much ! Augusto

[Dovecot] doveadm doesn't seem to honor mail_location, mail_uid, mail_gid
by Trever L. Adams 14 Oct '10

14 Oct '10

I am adjusting the recommended ldap configuration to match active directory instead of the standard posixaccount layout. The problem is that doveadm seems to ignore mail_uid and mail_gid along with (possibly) mail_location. This is a setup with all virtual users (all ldap, not system accounts). Everything works in postfix and standard dovecot operation, it is only doveadm which doesn't work. Ldap queries return everything but these entries (as they do not exist in AD). These items I have tried setting in the configuration and in environment variables. Any help would be GREATLY appreciated. Thank you, Trever -- "The three Rs of Microsoft support: Retry, Reboot, Reinstall." -- Unknown

[Dovecot] Why deliver+usercheck? deliver+MTA?
by Lukas Haase 14 Oct '10

14 Oct '10

Hi, I successfully configured dovecot using virtual users (and LDAP/AD). deliver is the LDA and verifies if the user exists (as recommended in the WIKI). However, the howtos in the Wiki say *nothing* about the case that the recipients should be verified *before* receiving the messages (prevent backscatter, ...). All configurations in the dovecot-Wiki (postfix and exim) just accept the mails and pass them to deliver. Also, all howtos which I found on the web. If the user does not exist, the mail is bounced because the mail was already accepted by the MTA. Nowadays this is an unacceptable configuration! Is there a special reason why there is no discussion about this? However, as postfix seems to be really too unflexible I have set up exim to handle incoming mail and do the usercheck in the router (with an LDAP query). But now the user is doubled-checked: Once when receiving with exim and a second time in deliver. This is not necessary, so I guess I can disable the LDAP query for deliver and set up a static userdb. Why does the Wiki recommened to verfify with deliver when the user needs to be checked at the MTA anyway? Regards, Luke

[Dovecot] Pigeonhole feature request: automatically copy sieve_global_path (default script) to user's sieve_dir
by Jerrale G 14 Oct '10

14 Oct '10

We have used the great managesieve you have merged together, with sieve, to create pigeonhole. However, when a user creates a custom script through a GUI of ours, the default, as we expected, would be ignored. Maybe you could add a retain_sieve_global=yes|no setting OR be more complex by having the sieve_global_dir copied to the users sieve_dir on first managesieve script save, if another setting to do this was set to yes. This way the administrators can create a skeleton directory and the users can retain the default skeleton settings. Maybe, in the future, you can do, just like the master auth for logging into users' imap accounts, you could have the master=yes allow login to each user's managesieve. Just some suggestions but, until a new feature comes around, I will have a cron job or a imap-login script do the trick. Timo has said that you are a separate developer from dovecot. I just want to thank you for the great job on sieve as well, Kudos, Jerrale G -- Jerrale G. SC Senior Admin

[Dovecot] Qmail+Vpopmail+Mysql+Dovecot 2.x (Notes on a successful conversion)
by Aaron 12 Oct '10

12 Oct '10

SoI had a hell of a time converting my qmail install to dovecot 2.0.5, so I thought I'd pass on what I learned. 1. When using vpopmail, do not use " --disable-many-domains". If you do, you'll need to recompile vpopmail without that setting and use the script found at http://qmailrocks.thibs.com/downloads/scripts/migrate-vpopmail-many-domains to collapse the tables. 2. Switch to mysql authentication. The following snippet works well. driver = mysql connect = host=/var/run/mysqld/mysqld.sock user=vpopmail password=YOURPASS dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 1008 AS uid, 1003 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' 3. When integrating Sieve, vpopmail apparently needs to own auth-master and authdb. (example available on request) 4. If coming from maildrop as the LDA, you can put the following in your maildroprc to allow a gentler transition (or to keep maildrop's ability to call external applications) `test -r /usr/libexec/dovecot/deliver` if ( $RETURNCODE == 0) { `test -r $HOME/$EXT/.sieve` if ( $RETURNCODE == 0) { to "| /usr/libexec/dovecot/deliver -d $EXT@$USER" } } 5. When completely switching, you can either replace the .qmail files or use one of the following in qmail/control/defaultdelivery |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $EXT@$USER |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d ${EXT/-*}@$USER -a $EXT@$USER -- This should allow a final conversion to vpopmail 5.5 (from 5.4.30) with dovecot 2.0.x.. I haven't done that final step yet, but it should now work. Anyhow, I hope this saves someone a few days of head scratching. a.

[Dovecot] Dovecot Version 1.2.12 Slow IMAP LIST Question
by Dave Shanefelter 11 Oct '10

11 Oct '10

We are using Dovecot 1.2.12, FreeBSD 8.1 Stable, & SquirrelMail 1.4.21 Our problem is that SquirrelMail works fine inside our Network, but from the outside SquirrelMail times out before it can display the inbox contents. SquirrelMail times out for everyone, all of the time. In troubleshooting we have observed the following: >From the inside, if I telnet into Dovecot IMAP and issue ? LIST "" "*" I get an instant list of my folders. If I do the above from the outside, the LIST command slowly lists 10 - 15 entries and stops, then pauses for what seems to be 30 seconds to a minute, then lists another 10 - 15 entries. After about 5 minutes of this it finally times out. An interesting note is, when it stops listing and pauses, it doesn't stop at the end of a line (folder entry), it stops half way through a line entry. For example, say the folder entry is mailfolder/folder1/folder2, when it stops I see mailfolder/fol I don't think this is a SquirrelMail issue because of the IMAP LIST problem. We have turned on debugging, but the logs really don't show much, just the timeout. Can anyone offer additional troubleshooting to help us track down this issue? Thanks

[Dovecot] ATTN TIMO: Man pages of "deliver"
by Jerrale G 11 Oct '10

11 Oct '10

The man pages of "man deliver" do not explain the "-n" option which is confusing a lot of people as to why mailboxes and mail folders aren't being automatically created; yet, the dovecot wiki's both say to use "-n" in postfix's master.cf which keeps dovecot's lda from automatically creating the folders. People are pulling hair over this! The default should be to not use -n as most will want their directories automatically created. The dovecot wikis, at least wiki1, also do not include the -e option to be more verbose to postfix, on error. Jerrale G.Jerrale G. SC Senior Admin

[Dovecot] login_* options for 1.0.15
by Hugo Monteiro 10 Oct '10

10 Oct '10

Hello all, Although i'm aware that version 1.0.15 is rather old, that's what is used in Lenny, so... Either way, the setup is rather simple, regular dovecot install, with maildirs residing on a "local" ext3 filesystem accessed through FC to a SAN (2Gbps link). The server has 2 cores (with HT), so "almost" 4 cores and 3GB of ram. A couple weeks ago we had a major number of account migrations, from POP to IMAP. We started to notice that in times of peaks, specially after lunch hour, dovecot started to get REALLY slow and closing client connections. A restart to the service was enough to get things working again. Firstly i thought about the max fd number per process, but after checking it turned out it was already rather large, 8192 in our case. I cannot observe any concerning I/O load either. Besides upgrading, are there any suggestions?

[Dovecot] Visible temp files as Imap Folder in INBOX

Hi all, I'm using dovecot-1.2.15 and NFS as storage of Maildir . When I try over IMAP and Evolution to move a mail to another Imap Folder, a file like .nfs000000000159816c0000245 is created and when move operation is finished, the file is deleted. Sometimes, this file isn't deleted and then, you can see a new imap folder called .nfs000000000159816c0000245 when you restart your Evolution or another Imap Client. Is this file created by dovecot? maybe, must dovecot delete this file on login? I think thats is easy fix this with a Post-Login script but I think that dovecot must delete it
