[Dovecot] Plugin trash does not work
by Nicolas Letellier 08 Apr '08

08 Apr '08

Hi. I use dovecot 1.0.13 on FreeBSD 7.0. I want my Junk mail will be deleted if my quota is exceeded. So, I configured trash plugin (with Dovecot wiki). In my dovecot.conf: protocol imap { mail_plugins = quota trash } plugin { trash = /usr/local/etc/dovecot-trash.conf } In my /usr/local/etc/dovecot-trash.conf: 1 Junk 2 Trash Emails in there mailboxes are never deleted. My mailbox is like this: .Junk dovecot-uidlist dovecot.index.log.2 tmp .Trash dovecot.index maildirsize cur dovecot.index.cache new dovecot-keywords dovecot.index.log subscriptions I want my .Junk directory be emptied when quota is exceeded. May i forgot something? Could you help me? Thanks very much! - Nicolas.

[Dovecot] Strange dmesg messages
by Raphael Bittencourt S. Costa 08 Apr '08

08 Apr '08

Guys, I'm getting strange messages on my new server with dovecot-1.1rc4 + lda + sieve + ldap + postfix + suse10. This server is in production since monday, and worked fine until today. The only thing I had changed was dovecot from 1.1rc3 to 1.1rc4. I already enabled mail_debug, but I got any erros after that. Does anyone have any idea of what is happening?

[Dovecot] dovecot and postfix virtual mailbox domains
by Dave 08 Apr '08

08 Apr '08

Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username, there's a maildir under that. In this case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account and being completely virtual. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd I'd appreciate any pointers. I think i am close, but am not seeing it. Thanks. Dave.

[Dovecot] feature request: deny IP address via database
by Dave McGuire 08 Apr '08

08 Apr '08

Hey folks. One feature I'd really like to see in dovecot is the ability to point it at a database (with a configurable query) and have it allow or deny a connection based on looking up the source IP address in that database. I run Postfix, and I've got it configured to use a database server for its smtpd_client_restrictions checks. Ideally I'd like to point dovecot at the same database table. I have external tools that maintain that table. I was thinking of writing it myself, but I'm running 1.0.10; I'd assume that any such modifications would need to be rewritten for 1.1. Then I got to thinking that such functionality would likely be useful to people other than just me, so.. Thoughts? -Dave -- Dave McGuire Port Charlotte, FL

I understand that the behaviour requested is similar to that of allow_nets (http://wiki.dovecot.org/PasswordDatabase/ExtraFields/AllowNets) but modified to explicitly deny some IPs (individually or in the range form). If so, probably some of the work should be already done. Sorry, I do not have the programming abilities enough to face this. Incidentally, I would like to notice that I opened a thread a few days ago regarding allow_nets and database (Bill's request needs to make use of an external database too) because I am not able to make allow_nets work properly when using an external DB *and IP ranges*. Maybe Bill would like to block single IPs so this bug? wold not apply to his case if an extension or adaptation of allow_nets is done. (My request, in case someone out there is curious: "Allow_nets + MySQL failing when using range notation") Regards, Javier

[Dovecot] A little assistance with Sieve
by cam＠ellisonpsychology.ca 07 Apr '08

07 Apr '08

With all the mess that my email has become, it makes sense for me to try to make use of Sieve, but I'm having quite the time finding out how to make it work. I'm running 1.0.13 on a Debian machine. Sieve appears to be compiled with it. I can access managesieve, and I have set up dovecot.conf with lda. I do not get a NO response when I PUTSCRIPI, but LISTSCRIPTS produces no result, so I assume it's not working properly, though if I try with a non-existent script I get an error message. Questions: 1. Is anyone else seeing this, or am I doing something wrong? 2. I have seen through Googling some dovecot.conf examples that suggest I should be using managesieve instead of lda (or in addition? - it's not clear), as in protocol managesieve { ... Any advice will be gratefully received.

[Dovecot] Problem with dovecot under Vmware Server
by Marvin Raab 06 Apr '08

06 Apr '08

Hi all, Recently installed dovecot and postfix under Fedora8 and it works great. Then I installed both postfix and dovecot under VMWare Server (different machine) copying the same configuration files but changing the hostname and domain as appropriate. When testing the installation using: telnet hostname 143, I receive * OK Dovecot ready But when I telnet on port 25, I receive: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Instead of: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 mail.kickspam.net ESMTP Postfix Naturally, I cannot send email. Outlook responds with Server timeout. I've rebooted and restarted services. I've checked poermissions and postfix master.cf How can I troubleshoot or does anyone have a quick answer? Thanks! Here's the output of dovecot -n and postconf -n The same config files are on both hosts and only the installation under VMWare Server has the problem.

[Dovecot] Broken Debian package
by Thing 06 Apr '08

06 Apr '08

Hi, I have run Dovecot via Debian for some years but in the last few weeks something has broken....I have been upgrading Debian but today rebooted it to try and sort out a failed DLT....now I find dovecot is non-functional.... So, Where to look for faults please? ie logs? can I make dovecot verbose? Thunderbird if telling me Dovecot is not imap4 compliant........and I cannot connect to it... I have tried re-installing Dovecot but the Debian package contains no dovecot.conf....so I have dovecot imap-d and dovecot common installed but no config. So I copied back the config files from a safe location....

[Dovecot] Leave mail on server leads to dup messages
by Arliss Jameson 05 Apr '08

05 Apr '08

Hi. I'm a dovecot newbie. I've set my pop client to leave messages on the server for 7 days. I'm downloading the same messages over and over as dovecot appears to be overwriting X-UID's in the mbox's. I can't think of any other program on the system that might write to the mbox other than postfix (and that program doesn't appear to be writing X-UID). My setup has one user (system account: vmail) that owns all mbox's. The user_query always returns vmail's home, uid and gid (you can view the SELECT's in the log snippet below).I have a total of four pop3 virtual mbox's. The example below illustrates what happens to one of them (though this problem extends to the others as well).

[Dovecot] Dovecot and stale nfs-locks hanging processes
by Søren Schrøder 05 Apr '08

05 Apr '08

Greetings dovecot mailing list. I have implemented a relatively big dovecot setup (250k users) and overall I am very pleased with dovecot functionality and performance. Setup description: * dovecot 1.0.x * FreeBSD 6.3 * Postfix (using dovecot deliver as LDA). * OpenLdap backend * Storage is NFS (Clariion EMC NFSd for Maildir, and FreeBSD NFSd for Indexes). * Locking is fcntl using RPC.lockd. * Users are accessing mail using POP3 and IMAP (IMAP mainly via Squirrelmail, but also direct) * 3 frontends for POP/SMTP and 2 frontends for IMAP (webmail). Round Robin DNS My problem: I am having issues where POP3, IMAP and DELIVER processes gets stuck, apparently waiting for device. fstat shows: bash# fstat -p 93522 USER CMD PID FD MOUNT INUM MODE SZ|DV R/W 302870 pop3 93522 root / 2 drwxr-xr-x 512 r 302870 pop3 93522 wd /home/mnt5 51592 drwxr-xr-x 80 r 302870 pop3 93522 text /usr 121619 -r-xr-xr-x 436616 r 302870 pop3 93522 0* internet stream tcp 302870 pop3 93522 1* internet stream tcp 302870 pop3 93522 2* pipe c778aa48 <-> c778a990 0 rw 302870 pop3 93522 3 /dev 24 crw-rw-rw- random r 302870 pop3 93522 5* pipe ce440b28 <-> ce440be0 0 rw 302870 pop3 93522 6* pipe ce440be0 <-> ce440b28 0 rw 302870 pop3 93522 7 /home/mnt5 9010290 -rw------- 1493 rw 302870 pop3 93522 8 - - bad - 302870 pop3 93522 9 - - bad - 302870 pop3 93522 10 - - bad And the inode in question on /home/mnt5 is a dot-nfs file, indicating stale lock: bash# ls -li | grep 9010290 9010290 -rw------- 1 302870 42 1493 Apr 3 18:05 .nfs.0668c236.6d524.4 ktrace on the pid shows absolutely no activity. The pop3 process is un-killable, and I end up stacking up pop3 processes from the user, as well as deliver to the user. Not healthy.. I was under the impression that POP3 would exit when a lock is set, preventing more than one pop3 processes pr. user, but it doesn't seem to be the case. Stopping dovecot entirely, leaves these stale pop3/imap/deliver processes hanging, even with shutdown_clients = yes The windows-problem-solution (reboot) seems to be the only way to get rid of the locked processes. So: Has anyone else observed this behavior, and eventually found the magic cure ? I wonder if there was a way to implement a "max wall-clock time" per dovecot process type (i.e.. terminate process after for example 120 sec. delivery, 600 sec pop3 etc...), as a crude "garbage-collector". Any hints/suggestions is welcome. -- Søren Schrøder

[Dovecot] LDAP auth_bind hangs and times out
by Jack McKinney 04 Apr '08

04 Apr '08

I have _almost_ got Dovecot working! One little snag... My users login using their email address as username. Each domain has their own LDAP subtree. Each user has an entry in the ou=users subtree of the domain subtree, and has a mail: field (inetOrgPerson) listing their email address/login name. I am trying to use auth_bind: when I login with jackmc(a)lorentz.com, dovecot should search for mail=jackmc(a)lorentz.com in the onelevel below ou=users,dc=lorentz,dc=com and find me as "cn=Jack McKinney,ou=users,dc=lorentz,dc=com". I have created an entry in LDAP (varmail) that should be able to do this query. Indeed, from the command line, it works: ldapsearch -h ldap.lrtz -b 'ou=users, dc=lorentz, dc=com' -D 'cn=varmail,ou=users,dc=lorentz,dc=com' -x -W -s onelevel '(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))' Enter LDAP Password: # extended LDIF # # LDAPv3 # base <ou=users, dc=lorentz, dc=com> with scope oneLevel # filter: (&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) # requesting: ALL # # Jack McKinney, users, lorentz.com dn: cn=Jack McKinney,ou=users,dc=lorentz,dc=com objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson cn: Jack McKinney givenName: Jack McKinney sn: McKinney mail: jackmc(a)lorentz.com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 ' However, it appears that dovecot performs the above query successfully, but then never uses the password and retrieved DN to attempt to bind and authenticate the user. Instead, it just times out. My dovecot-ldap.conf is: hosts = ldap.lrtz dn = cn=varmail,ou=users,dc=lorentz,dc=com dnpass = ********* ldap_version = 3 auth_bind = yes pass_filter = (&(objectClass=inetOrgPerson)(mail=%Lu)) base = ou=users, dc=%Dd scope = onelevel The dovecot log shows: Apr 3 08:13:21 fourier dovecot: auth(default): new auth connection: pid=15774 Apr 3 08:13:30 fourier dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=x.x.x.x^Irip=y.y.y.y^Iresp=<hidden> Apr 3 08:13:30 fourier dovecot: auth(default): ldap(jackmc(a)lorentz.com,y.y.y.y): bind search: base=ou=users, dc=lorentz,dc=com filter=(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) Apr 3 08:16:30 fourier dovecot: imap-login: Disconnected: Inactivity: method=PLAIN, rip=y.y.y.y, lip=x.x.x.x, TLS The OpenLDAP log shows that the query is received and that it returns a match: Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH base="ou=users,dc=lorentz,dc=com" scope=1 deref=0 filter="(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))" Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH attr=uid Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SEARCH RESULT tag=101 err=0 nentries=1 text= When I do the query from the command line, there is an additional pair of lines: Apr 3 08:18:10 fourier slapd[16106]: conn=22 op=2 UNBIND Apr 3 08:18:10 fourier slapd[16106]: conn=22 fd=28 closed I thus conclude that Dovecot is not closing the connection. -- Jack McKinney GPG 1024D/99C6A174 jackmc(a)lorentz.com YM:lfaatsnat2006 AIM:jackmclorentz "There is no parameter that makes it impossible for you to perform still more excellently." -Mario Cuomo, on the lack of a clock in baseball

[Dovecot] "Dumb" proxying?
by Dan Bongert 04 Apr '08

04 Apr '08

I'm a database noob, and it really seems like it would be overkill for my setup: I just want to proxy all connections from my DMZ to my internal mail server -- same internal server for all users. I used to use perdition for this set up, but am having issues getting it to play nicely with my new servers. Can I bypass all of the SQL stuff and just have dovecot forward all POP/IMAP connections to a specific server? Or perhaps set up a wild card lookup in the database (preferably something serverless like sqlite) so that no matter the query, it'll return one server? I don't really want to add "database management" to my list of jobs I have to do, especially for ~1000 users, and when I don't handle user creation/deletion. -- Dan Bongert dbongert(a)ssc.wisc.edu

[Dovecot] outlook2007 shows frequent imap disconnect no matter what outlook-idle setting in dovecot.conf
by Kielbasiewicz, Peter 04 Apr '08

04 Apr '08

Hello, I saw the problem quite often in various posts but could not find a real solution . Problem is that I frequently get annoying popups from outlook 2007 about imap idle timeouts which block working with outlook until the popup is acknowledged. The popup says: Your IMAP server closed the connection. This can occur if you leave the connection idle for too long. Protocol: IMAP Server: testhost Port: 143 Error Code: 0x800CCCDD I tried to run dovecot with or without "imap_client_workarounds = outlook-idle" but do not see any difference. I am running dovecot on Red Hat Enterprise Linux Client release 5.1 (Tikanga). Below is the output of some commands to get a clue about my config. Background info: Our primary mailboxes are on exchange servers. As there is a size limit on the server mailboxes I am evaluating a local storage solution for our users. Thus I set up an additional mailbox in outlook using IMAP. Local .pst files can not be backuped easily (especially when outlook is running) and I am investigating a local IMAP server where users can move their mails to. This server can easily be backuped (even incrementally when using Maildir) and users do always have access to their mails. The drawbacks are that users must have an extra login to the imap server because I have no ldap access to the company AD server from our local site domain. The solution will not be accepted though if I can not prevent the frequent disconnect popups.

[Dovecot] Confusion of Sieve filter scripts and the file separator. (Amatuer Siever)
by Jack 04 Apr '08

04 Apr '08

Hello, I have just been playing around with sieve filters to split up all my incoming mail into the correct directories. I have created some subdirectories to put mailing list emails in and just want to check if my thinking is correct. I am using namespaces with the '/' character as the separator. When creating the fileinto line on my sieve scripts I thought I would have to use the '/' character to separate the folders (as horde mail also does), but that doesn't work (and produces a "Invalid folder" error) instead I must use the '.' character. I am using the dovecot deliver module and managesieve for my sieve stuff (dovecot 1.0.13). I am just wondering if this is the correct behaviour or if it is a bug of sorts. Cheers. From, Jack

[Dovecot] Icedove (Thunderbird) crashes when reading IMAP messages
by Cam Ellison 04 Apr '08

04 Apr '08

This is a Debian lenny/sid installation. Dovecot has been installed on it for over a year, with no problems. Lately (i.e. the past few months), if I attempt to read a message, Icedove crashes. It does not do this when I read a message downloaded from the ISP's POP3 server (not that I do this very often - almost all my mail goes through Dovecot). I am now having to read email with KMail, but cannot send from it - that's another story. Googling for the past month or so reveals nothing: there seems to be no bug filed for this, and indeed I think it is an odd communication problem with dovecot that has not been seen before. Has anyone any experience with this, or any ideas how I should go about resolving it? I have not done so (because I don't know how to use the data, not being a coder), but can run strace and/or valgrind on icedove if that will help.

[Dovecot] Lmtp between hosts? (postfix/dovecot/ldap)
by k bah 02 Apr '08

02 Apr '08

I have 2 hosts: (a) - dovecot-1.0.5-6 - postfix-2.4.5-20 -> It's not the mx record for the domain, just holds the mailboxes -> Postfix uses LDAP for user lookup, dovecot too. -> Works ok if I set it to be the final mail destination, with Cyrus and Dovecot LDA (mailbox_transport). -> Has no domain associated (dns) with this ip address (b) - postfix-2.3.2-28 -> Has the mx record for that domain, has ip address that the domain points to. (users @ domain.org) -> Works ok if I install dovecot and set the mailbox_transport to be on this machine, both with dovecot and cyrus. What I'm trying to do: Have host (b) to receive mails for that domain, and by setting it's transport_maps to be /etc/postfix/transport, and there (tranport maps) point to host (a), using ltmp: "domain.org lmtp:ip_address_machine_A:24" ("domain.org lmtp:inet:ip_address_machine_A:24" does not work, gives me "fatal: valid hostname or network address required in server description: inet:ip_address_machine_A:24") Both machines have /etc/services with lmtp to port 24 tcp/udp. http://www.postfix.org/transport.5.html was not so clear to me. Ok, when I took out the "inet" part on the transport maps file, it connected to the host (a), which has this on master.cf: "machine_A_ip_address:24 inet n - n - - lmtp" it "worked", since machine (b) (received the mail and has mx record) delivered the mail to machine (a) (holds mailboxes, runs dovecot), but that stopped, machine (b) connects to port 24 on machine (a), and stays there, connected, without saying nothing (sniffed it). When I kill the connection (kill postfix on machine (a)), machine (b) complains on the log file: postfix/lmtp[704]: msg_id: to=<xx(a)xx.yy>, relay=machine_A[machine_A]:24, delay=223, delays=0.08/0.01/223/0, dsn=4.4.2, status=deferred (lost connection with machine_A[machine_A] while receiving the initial server greeting). -- questions -- I don't know if I'm doing things wrong (configuration error) or the wrong thing (should try other ways), so my questions: 1) Is this setup going to work ever, or it's wrong to try to get it to work? I want to hold mailboxes on a different host, and now I got to use dovecot (in case I hear: "try it with cyrus instead" =o)). 2) Viewing from the machine that receives the mail, and has mx record, the transport should be lmtp, right? Since it's now a matter of "delivery". Postfix: <...> -> <qmgr> -> (<local> or <smtp> or <pipe>) When using lmtp, I'm in <local>?? I mean, to get the message to the other machine (just mailboxes, no mx) I SHOULD USE LMTP(?) 3) Viewing from the machine holding the mailboxes, is there a way to make dovecot listen on that port? Or should I continue to use Postfix, and use postfix on this machine to deliver to dovecot (dovecot lda config works ok if using 1 and only 1 machine for everything - mx record, mailboxes). With Cyrus I talked lmtp directly, Postfix receives the mail and uses lmtp to talk to cyrus, using a unix socket. If anyone replies to the topic, and the discussion goes deeper on some of the alternatives, I paste my configs and come with further details, since what's working isolated I didn't paste here. Previous tests with just Cyrus or Dovecot on 1 machine setup worked, so I think it would just "bloat" the mail with information. thanks = -- Powered by Outblaze

[Dovecot] Alert when quota is warning

Hello. Is it exist a plugin to alert when a POP/IMAP account has a warning quota (like 90%)? Or, do you know a solution to do it? The alert could be an email sent. Thanks. - Nicolas.
