[Dovecot] install question
by Gerard Ranke 04 Apr '11

04 Apr '11

Dear list, I'm trying to build a dovecot-2.0.11 package for our systems, and so I would like to install it to a temporary directory. But when I use "gmake DESTDIR=/tmp/build install", instead of binaries, it's wrapper scripts that get installed for dovecot, doveconf and doveadm. When I install to the default location all is well. Does anybody know how how to install to a temp location? Thanks in advance for your answer! Best regards, Gerard Ranke

Hello Switching for Dovecot 1 to 2, I noticed the machine respond slower to users requests , of course it works but response times are a bit longer. Does Dovecot 2 need more system ressources ? ( the machine is the same ) Thanks

[Dovecot] Segmentation fault with vpopmail auth
by Samuel Montosa 04 Apr '11

04 Apr '11

Hi. I am new in the list. First, excuse my english. I am not native speaker. A few hours ago I had a problem with process dovecot-auth and vpopmail. Versions I had using, working, were: vpopmail 5.4.28 dovecot-1.1.12 I tried to compile dovecot-1.2.16. Compilation was well but in execution system said: kernel: dovecot-auth[2842]: segfault at 645f20 ip 0000000000645f20 sp 00007fff69bd3708 error 15 in dovecot-auth[645000+1000] and so. Then, I tried to recompile dovecot-1.1.12 (original version I had working) but system said the same. After investigation, I saw I had mixed of vpopmail versions. Problem was I had /home/vpopmail/lib/libvpopmail.so in my system. When this file is present, compilation of dovecot link dovocot-auth to dynamic library libvpopmail.so, but it is not necessary since I had my system working using vpopmail without this .so. What I recommend is to compile a fresh vpopmail. Now I am using vpopmail-5.4.32 (at now, stable version) and dovecot-1.2.16. First, compile vpopmail and make sure you purge /home/vpopmail/lib/ of libvpopmail.so. Fresh installations of vpopmail, from tar.gz (not from SVN) _doesn't_ build libvpopmail.so, so make sure this file doesn't exist before you compile dovecot. For me, library dependencies are: mymachine:/usr/local/src/dovecot-1.2.16# ldd src/auth/dovecot-auth linux-vdso.so.1 => (0x00007fff63df5000) libpam.so.0 => /lib/libpam.so.0 (0x00007f9f925e1000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f9f923aa000) libdl.so.2 => /lib/libdl.so.2 (0x00007f9f921a5000) librt.so.1 => /lib/librt.so.1 (0x00007f9f91f9d000) libc.so.6 => /lib/libc.so.6 (0x00007f9f91c3c000) /lib64/ld-linux-x86-64.so.2 (0x00007f9f927f7000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f9f91a1f000) I hope this helps. It was a strange "bug". Regards. -- Samuel Montosa

[Dovecot] Maildir
by Walt Shekrota 01 Apr '11

01 Apr '11

I noticed in Cyrus they seem to address maildir++ recognised by IMAP. I need to know does Dovecot recognise this format? Procmail has an ability to deliver mails to different folders which if unrecognised renders the whole process useless. Does Dovecot have a similar deliver method? Thanks. -Walt

[Dovecot] inotify and network/cluster filesystems
by Jan-Frode Myklebust 01 Apr '11

01 Apr '11

(dovecot v1.2.16) I've notice the log notices about increasing /proc/sys/fs/inotify/max_user_instances on my servers, and started wondering if inotify works for network/cluster filesystems.. I found this: http://www.ibm.com/developerworks/forums/thread.jspa?threadID=311194 which says that there's no mechanism for one node to tell another node that a directory changed for GPFS.. And I would assume the same applies for NFS and other network filesystems. (Yes I know, we should use director to make users sticky to one host -- but we're not yet ready for that for lmtp). So, are there any recommendations for what settings one should use for for filesystems where inotify woun't work ? Are there settings for disabling it (without recompiling)? And does mailbox_idle_check_interval happen in addition to inotify, so that clients will be notified even with a broken inotify ? -jf

[Dovecot] Sieve: unknown tagged argument ':create' for the fileinto command
by mailing＠securitylabs.it 01 Apr '11

Hello, I've upgraded from dovecot 1.2.x with sieve to dovecot 2.0.11 with sieve. I've noticed that folders are no more created at delivery time now. I've read that I have to do two things: lda_mailbox_autocreate = yes in dovecot.conf and fileinto :create in the sieve script. Now the error message I receive is: error: unknown tagged argument ':create' for the fileinto command (reported only once at first occurence). My sieve script: require ["date", "variables", "fileinto"]; if header :contains "subject" "Bacula:" { if currentdate :matches "month" "*" { set "month" "${1}"; } if currentdate :matches "year" "*" { set "year" "${1}"; } fileinto :create "INBOX.Bacula.${month}-${year}"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } My dovecot conf: papua:/usr/local/bin# dovecot -n # 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 auth_cache_negative_ttl = 2 mins auth_cache_size = 1000 M auth_cache_ttl = 2 mins auth_mechanisms = plain cram-md5 apop auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& disable_plaintext_auth = no first_valid_uid = 100 last_valid_uid = 105 lda_mailbox_autocreate = yes lock_method = dotlock log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_fsync = never mail_gid = Debian-exim mail_location = maildir:~/Maildir mail_privileged_group = Debian-exim mail_uid = Debian-exim managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } plugin/mail_log_events = delete expunge plugin/mail_log_group_events = plugin/quota = maildir plugin/quota_warning = storage=80%% /usr/local/bin/dovecot-quota-warning.sh 80 plugin/quota_warning2 = storage=90%% /usr/local/bin/dovecot-quota-warning.sh 90 plugin/sieve = ~/.dovecot.sieve protocols = imap service auth { unix_listener auth-userdb { group = Debian-exim mode = 0600 user = Debian-exim } } service imap-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service imap { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } service pop3-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service pop3 { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } ssl_cert =</usr/local/etc/dovecot.crt ssl_key =</usr/local/etc/dovecot.key userdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify quota imap_quota mail_log" } protocol lda { mail_plugins = quota sieve postmaster_address = postmaster(a)me.com }

[Dovecot] Mail_location and formats
by Walt Shekrota 31 Mar '11

31 Mar '11

Hi, Ok I know that the Maildir hierarchical structure works because I saw it intermittantly in my setup. At times I could look at ALL folders in my client. mail_location = maildir:~/Maildir:LAYOUT=fs http://wiki1.dovecot.org/MailLocation/Maildir this says 1.1 only? My maildir folder has a collection of maildir folders ie each has cur new tmp folders. As an experiment I took the cur new tmp out of my INBOX folder and put it in the root of Maildir. This worked with dovecot using the inbox only or the standard maildir++ format. Although it would not see the old mail in the folder not sure why. mail_location = maildir:~/Maildir This setup also ignores the remainder of folders. I know the dovecot support of maildir is shakey due to standards compliance but this is crazy ... and unusable. Does ANYONE have a working maildir setup in the hierarchical layout? Maildir/ inbox mail-sent outbox otherfolder Fred Sue Thanks. -Walt

[Dovecot] POP3 connection issue & SASL not compiled in
by sunhux G 31 Mar '11

31 Mar '11

After I've configured dovecot for SSL according to the info given in the link below: https://access.redhat.com/kb/docs/DOC-6671 (tried both POP3 & secure POP3 & got the same result) I tested POP3 access from my unblocked (no firewall rule for outgoing) broadband PC's Outlook to connect to the postfix/dovecot server & got the following : Tasks Status ===================== ======== Establish network connection Completed Find outgoing mail server (SMTP) Completed Find incoming mail server (POP3) Completed Log onto incoming mail server (PO... Send test e-mail message Completed (yep, this email was received in postfix mailbox) & seconds later, the following messages returned: Log onto incoming mail server (POP3): The specified server was found, but there was no response from the server. Please verify that the port and SSL information is correct. To access these settings close this dialog, then click More Settings and click on the Advanced tab. Find incoming mail server (POP3): Outlook could not connect to the incoming mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSL settings in More Settings under the Advanced tab. Q1: What do I need to provide to this list for further troubleshooting? Q2: I have the following log entry in /var/log/mailog : Mar 31 10:48:36 hostname postfix/smtpd[22258]: warning: smtpd_sasl_auth_enable is true, but SASL support is not compiled in Is this related to my POP3 connection issue? Q3: Is the following related to the sasl issue in Q2 & the POP3 connection issue ?

[Dovecot] How to grant a kerberos ticket after successful imap authentication from dovecot
by André Rodier 31 Mar '11

31 Mar '11

Hello everybody, I hope this question is appropriate for this list. Apologies if not. I am running a set of virtual machines under debian 6, to build a mail/collaboration server. I am mainly using dovecot, postfix, openldap and heimdal. Mails are stored using maildir, on a NFSv4 share. My users are system users, but using LDAP and libpam-ldap and libnss-ldap for caching credentials information. Everything is working as expected, well, /almost/. Since NFS is using kerberos, by defaults, my users are not able to access their mail storage if they have not received their kerberos ticket. For instance, if I do nothing, this is the errors I have from dovecot when trying to logon using any imap client: Mar 31 09:33:07 titan dovecot: imap-login: Login: user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 31 09:33:07 titan dovecot: dovecot: Fatal: chdir(/home/emails/team/arodier/) failed: Permission denied (euid=1003(arodier) egid=1001(red2team) missing +x perm: /home/emails) Mar 31 09:33:07 titan dovecot: dovecot: child 5089 (imap) returned error 89 (Fatal failure) However, if I just login on a console for the user "/arodier/", I see that I have received a ticket, and I can see it with klist: Credentials cache: FILE:/tmp/krb5cc_1001_ywvktf Principal: arodier(a)RED2.SRV Issued Expires Principal Mar 31 09:25:55 Mar 31 19:25:53 krbtgt/RED2.SRV(a)RED2.SRV Mar 31 09:25:57 Mar 31 19:25:53 nfs/ananke.red2.srv(a)RED2.SRV Once I have simply logged myself on a console, I can access my emails using any IMAP client. The question is: How should I configure libpam (or dovecot ?) to initialise/receive a kerberos ticket after successful authentication ? Thanks for your answers.

[Dovecot] debugging mail_location issues
by Walt Shekrota 31 Mar '11

31 Mar '11

Type of Maildir structure I am using came from KDE. No '.'s just folders. something like Maildir/ INBOX mail-sent outbox other where each has cur new and tmp folders. if I access this directory with IMAP it creates cur new and tmp in the root. ie Maildir/ INBOX cur new tmp mail-sent outbox other This implies to me 1. it finds the Maildir directory 2. it apparently does not have access to the directories like INBOX so it makes its own in the root? or is this a side effect I'm misunderstanding? The resulting IMAP session shows an empty INBOX only (this must be the cur new tmp it added) The real INBOX is not accessible but still intact. In a session this morning I could access all the folders just not the real INBOX. INBOX was as is here empty with cur new tmp in the root of the Maildir folder. This behavior makes no sense. I'm using the hierarchical structure as pointed to in. http://wiki1.dovecot.org/MailLocation/Maildir It appears my grief surrounds dovecot's detection of mailbox. This is kind of what I said days ago. Setting up requires you to know expected states. Something in my environmment I haven't been able to identify (yet) is influencing recognising that hierarchical maildir structure. -Walt

[Dovecot] Message file prefetching to memory
by Timo Sirainen 31 Mar '11

31 Mar '11

I added a new mail_prefetch_count setting to Dovecot v2.1 (http://hg.dovecot.org/dovecot-2.1/) Its main purpose is to avoid unnecessary latency while waiting for replies from remote server with imapc, i.e. instead of doing (FETCH, wait, FETCH, wait, ...) it can do (FETCH, FETCH, .., wait). For the same reason it's also going to be very useful once I add support for key-value databases / other high latency cloud filesystems. It also works with Maildir, single-dbox and cydir backends by calling posix_fadvise(POSIX_FADV_WILLNEED) for the files. This syscall is apparently only implemented by Linux. It should tell the kernel to start reading the files from disk to page cache. By calling this for multiple files, it should help the kernel optimize disk I/O. For example if 10 files are prefetched, the kernel might figure out that it should read them in a different order to avoid extra disk seeks. Perhaps it also does something useful with NFS, I don't know. I'm not sure if it would be a good idea to use this for mbox or multi-dbox files, since they already have multiple messages in same file so kernel probably already did some prefetching. With mdbox I guess it could be useful if the message file changes.. This optimization currently works only for FETCH command (and POP3 RETR and TOP). SEARCH/THREAD/SORT commands will hopefully implement it soon also. I'd be interested in knowing what the effects of this setting are if anyone tests this some day.

[Dovecot] v1.2.12 and debug
by Walt Shekrota 30 Mar '11

30 Mar '11

Is there some kind of extended debug that might show why my maildir is not foundat login? It has worked off and on, once briefly today then no more. I'm going around twiddling knobs guessing at this point which is foolish. I need some real bread crumbs to indicate what is going wrong. I've tried all kinds of .conf file ... example file etc. I figured using the least number of settings should get me somewhere but I still have no luck. I'd love to just give up and load that PPA for 2.x but I have no idea what package to install in debian. (I have the PPA update) Thanks. -Walt

In 1.2.12 or there abouts how do changes in the dovecot.conf happen? After doing the sig HUP I have noted there is generally a delay in the recognition of items in my .conf. An example I had logging set off, turned it on and it was several restarts before I again saw logging? This delay is driving me nuts in trying to figure out what needs to change. Thanks. -Walt

[Dovecot] migrating to dovecot
by Alexandre Chapellon 30 Mar '11

30 Mar '11

Hello, I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons: - The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir) - I don't have direct access to the filesystem where the mails are stored. The best I could do would be a snapshots of the filesystem - I have about 1,5TB of mail data. - Having users to be forced to empty their mailbox before migration or re-download their whole mailbox after migration would be something hard for me to present as a correct option. Am looking for advices that would avoid me loosing time searching in bad directions. Or even point me to a miraculous tool thatdoes all magic while i have a beer :) Best regards. -- horoa: la voie est libre

To elaborate, if there is a database associated with this setup it is really fubar. note: tail of dovecot -n lda: postmaster_address: postmaster mail_plugins: sieve quota_full_tempfail: yes deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 504 socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve This in no way represents the settings in my dovecot.conf. It seems to have rembered old .conf settings and mixed them. At no time was mode 504 set or even 432. What am I doing wrong? Thanks. -Walt I'm also toying with the idea of loading 2.x if I can figure out the PPA stuff.
