[Dovecot] Strange Login / Timeout Sessions
by Carlos Mennens 20 Dec '11

20 Dec '11

I have my webmail application tied to Postfix / Dovecot server & now for some reason the IMAP sessions oddly time out throughout the day and then logging back into the mail system over the web is painfully slow. The only thing I've seen that fixes it is to reload the Dovecot daemon in Linux: /etc/init.d/dovecot reload Once that command is ran, my webmail login is super fast and moving from folder to folder is extremely fast again. Then in about a few hours, the session will time out and this problem repeats. The problem is the same for everyone and not just a few user accounts. Anyone have any idea what I should be looking for or looking at? My Dovecot logs or mixed in /var/log/maillog which is extremely hard to watch live & gets mixed with Postfix, Amavisd, and Postgrey. Any ideas or suggestions to narrow this problem out? I'm running Dovecot-1.0.7-7.el5_7.1. I saw this load on the console today: Error: Dovecot is already running with PID 2334 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf Below is my configuration file: [root@mail ~]# dovecot -n # 1.0.7: /etc/dovecot.conf protocols: imap ssl_ca_file: /etc/ssl/certs/digicert.crt ssl_cert_file: ***OMIT*** ssl_key_file: ***OMIT*** login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] Two important new Pigeonhole v0.3 features
by Stephan Bosch 19 Dec '11

19 Dec '11

Hello Dovecot users, Pigeonhole v0.3 for Dovecot v2.1 has two new features I would like you to play with before I make a first release: 1) The new Sieve editheader extension (http://tools.ietf.org/html/rfc5293) This allows modifying the headers of the message before delivery. This is actually the first implemented extension that can modify the message itself in any way. This feature adds quite a bit of new code that I'd like to see tested more thoroughly. 2) The new sieve-filter tool (documented in the sieve-filter(1) man page upon installation). This allows (re-)filtering messages that are already stored in a particular mailbox. It preserves the assigned IMAP flags and keywords and using the imap4flags extension these can also be modified. It also plays nice with the editheader extension. Judging by postings in this mailing list from the last few years, this is a highly-demanded feature and I'm glad that I finally got around to finish this thing. If the new sieve-filter tool is lacking certain features in your opinion, just let me know. Needless to say: read the man page carefully and watch out with important mail. This is currently only available from the mercurial repository, but if you prefer to have an .rc1 release first, just tell me and I'll make one. The automatic Debian repository already includes these features. Regards, Stephan.

[Dovecot] IMAP and sieve
by moozer 19 Dec '11

19 Dec '11

I am currently setting up an IMAP server for archiving purposes. The goal is to drag an email to the IMAP folder, and then have a server-side sieve script to put it in the right folder. One of the sources used was this wiki entry http://wiki.dovecot.org/LDA/Sieve/Dovecot I added the mail_plugins = sieve to /etc/dovecot/15-lda.conf and after some exim4 fiddling, mails delivered are filtered by my sieve script. Doing the same for imap delivery (in /etc/dovecot/20-imap.conf) give the following error Dec 19 10:22:09 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:09 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:09 leon dovecot: imap: Fatal: Couldn't load required plugins Dec 19 10:22:10 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:10 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:10 leon dovecot: imap: Fatal: Couldn't load required plugins I notice this part: "plugin is intended to be used only by binaries: lda lmtp (we're imap)" So the question is if it is possible to run sieve server-side sieve scripts on emails copied using IMAP. Suggestions are most welcome. Moozer -- I am running debian testing # dovecot --version 2.0.15

[Dovecot] DKIM Verification failures
by Nikolaos Milas 18 Dec '11

18 Dec '11

Hi, -- This message refers to the maillist itself rather than to dovecot software -- I have noticed that when I post to this list (only), I get DKIM Verification failure reports from: root(a)moncton.sidefx.com (e.g. for my last post: "DKIM failure report for job 4D27B5DC4E on mail.sidefx.com") root(a)mail.rmacd.com (e.g. for my last post: "DKIM failure report for job B69B3187F1 on mail.rmacd.com") root(a)mx0.roessner-net.de (e.g. for my last post: "DKIM failure report for job 6103B52092 on mx0.roessner-net.de") I have not had other DKIM failure reports from anywhere and I know that we should not have issues with it. An example from gmail: Authentication-Results: mx.google.com; spf=pass (google.com: best guess record for domain of nmilas(a)noa.gr designates 195.251.204.235 as permitted sender) smtp.mail=nmilas(a)noa.gr; dkim=pass header.i=(a)noa.gr So, whom should I contact to investigate this problem? Thanks, Nick

[Dovecot] logging deletion of emails through IMAP?
by John Brock 16 Dec '11

16 Dec '11

Version 1.2.16: Is there some way to enable logging for when emails are deleted via IMAP? All I see are log entries for users logging in/logging out. It would be nice to know when an email is deleted, and from which IP address the user was logged in when s/he deleted the email. -- John Brock Adeptive Software 303-554-0301 x1

[Dovecot] simultaneous scripts not running via sieve_before
by Scott Lewis 16 Dec '11

16 Dec '11

Hi again everyone, So I've finally got sieve integration happening on my REHL Postfix/Dovecot server, with private user scripts happily running when users create them. (we user SquirrelMail, so the avelsieve plugin runs the sieve integration). Now I'd like to utilise additional per-user scripts (probably via sieve_before), but I've not been able to get my additional scripts to execute. I am doing the following: a) getting avelsieve to write my redirect script (ie. logging on as user, completing private script wizard, and activating it) b) compiling .dovecot.sieve with sievec c) copying the resultant .dovecot.svbin to sieve/ directory (and renaming it eg redirect.svbin still, it appears that each /home/%u/.dovecot.sieve file is the only one taking effect. Any thoughts on how to make the other ones active? (The idea behind this is to automatically forward all of joeuser@mydomain's incoming mail to somewhere like joeusersbackup(a)gmail.com, for backup reasons. One day, I'll work out how to configure postfix to do this for all outgoing email too, but that's for another day :) Below are what my .conf files look like. Thanks in advance, Scott /etc/dovecot.conf: [code] protocols = imap imaps managesieve listen = * protocol imap { #mail_plugins = sieve quota } ## ## ManageSieve specific settings ## protocol managesieve { # debugging mail_debug = yes #login_executable = /usr/libexec/dovecot/managesieve-login #mail_executable = /usr/libexec/dovecot/managesieve #managesieve_max_line_length = 65536 #managesieve_logout_format = bytes ( in=%i : out=%o ) #managesieve_implementation_string = Cyrus timsieved v2.2.13 } protocol lda { mail_plugins = sieve quota sieve=~/.dovecot.sieve sieve_extentions = +include sieve_dir=~/sieve sieve_before = /home/%u/sieve/redirect.svbin sieve_global_path = /etc/globalsieverc.svbin [/code]

[Dovecot] dovecot-antispam: pipe backend with spamc failing to parse args
by Micah Anderson 15 Dec '11

15 Dec '11

I'm trying to get the pipe backend to work with the new dovecot-antispam (I was very pleased to see the new version, thanks Johannes!) Before I would run the following over the maildir: spamc -d 10.0.1.109 -L ham < $file 2>&1 > /dev/null now, i'm using dovecot-antispam and mdbox and have the following configured: antispam_backend = pipe antispam_signature = X-Spam-Flag antispam_signature_missing = error antispam_trash_pattern = trash;Trash;Deleted * antispam_spam_pattern_ignorecase = SPAM antispam_pipe_tmpdir = /var/tmp antispam_pipe_program_spam_arg = -L spam antispam_pipe_program_notspam_arg = -L ham antispam_pipe_program = /usr/bin/spamc antispam_pipe_program_args = -d 10.0.1.109 Now, when I move a message to Spam, dovecot-antispam detects it and attempts to run, but it fails: Dec 14 16:22:45 grosbeak [username 10.0.1.74 uid]: antispam: run program failed with exit code 64 Exit code 64 is spamc's exit code for "command line usage error" - but I can't see exactly the command that is being constructed by dovecot-antispam to know where the error is. Any ideas? micah --

[Dovecot] Two recent issues
by Brad Schuetz 14 Dec '11

14 Dec '11

I've been using dovecot for years, been working great. However recently I've come across two issues. The first issue unfortunately I have little information on, mail_debug hasn't provided anything useful either (in fact it looks like the login request that fails doesn't even get logged at all). During the morning rush of email, this server has around 11k mailboxes on it, it *appears* that one of the auth processes dies resulting in "dovecot: imap-login: Error: read(imap) failed: Connection reset by peer" errors followed by "dovecot: imap-login: Internal login failure ..." in the logs. I've yet to get any useful debugging information on this error so I'm not expecting much/any help on this one, but if anyone has any ideas on how I can get more debug besides running strace 24/7 in the hopes it catches something before the hard drive is full of strace output I'd love to hear it. The best I've gotten was a lucky strace once (at the time I didn't realize it was so lucky or I would have saved the output) that indicated the imap-login daemon was failing to connect to the auth process. The second issue is lmtp/lda (tried both) delivery to a mailbox that has filesystem quotas enabled and the group quota is maxed is resulting in the below panic and crash. This issue happens with 2.0.13, 2.0.15 and 2.0.16. Here's the logs showing that it knows the disk quota is exceeded and then a subsequent zlib panic. Like it's trying to deliver it anyway. --------------------- 11:21:07 [err] dovecot: lmtp(29691, admin(a)[redacted].com) Error: o_stream_send_istream(/email/d/r/[redacted]/[redacted]/admin/Maildir/tmp/1323458467.M245978P29691.fenrir.omnis.com) failed: Disk quota exceeded 11:21:07 [crit] dovecot: lmtp(29691, admin(a)[redacted].com) Panic: file ostream-zlib.c: line 144 (o_stream_zlib_send_flush): assertion failed: (zs->avail_in == 0) 11:21:07 [err] dovecot: lmtp(29691, admin(a)[redacted].com) Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x345443ca90] -> /usr/lib64/dovecot/libdovecot.so.0 [0x345443cae6] -> /usr/lib64/dovecot/libdovecot.so.0 [0x345443c4a3] -> /usr/lib64/dovecot/lib20_zlib_plugin.so [0x2ba2d31547f6] -> /usr/lib64/dovecot/lib20_zlib_plugin.so [0x2ba2d315481b] -> /usr/lib64/dovecot/libdovecot.so.0(o_stream_flush+0x2a) [0x345444f0ea] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_save_finish+0x6b) [0x3451c63b6b] -> /usr/lib64/dovecot/lib10_quota_plugin.so [0x2ba2d2f4ce7a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_save_finish+0x30) [0x3451c2fbb0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0xb3) [0x3451c2aae3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_copy+0x56) [0x3451c6fd36] -> /usr/lib64/dovecot/lib10_quota_plugin.so [0x2ba2d2f4d0ba] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_copy+0x5a) [0x3451c301ba] -> /usr/lib64/dovecot/li 11:21:07 [err] dovecot: master: Error: service(lmtp): child 29691 killed with signal 6 (core dumps disabled) --------------------- Attached is the current "doveadm config" output. -- Brad Schuetz

Re: [Dovecot] Questions about single intance storage
by Maria Arrea 13 Dec '11

Hello Timo. If we can not safely restore from backup a user's mailbox with SiS enabled, we can not enable SiS. Any plan to include this backup recovery tool in dovecot 2.0.X or 2.1? Regards Maria > 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Hm. Yes, that is problematic.. Even if you knew what SIS files were used, there's no simple way to restore those with proper refcounts. I think what really should be done is writing a tool that can create/restore backups, possibly de-SISing the attachments..

[Dovecot] Saving archive copy of all mail sent/received w/Dovecot+Postfix?
by Andrew M 12 Dec '11

12 Dec '11

I'm running Dovecot 2.0.15 and Postfix 2.7.7 with postfix handing off to Dovecot's LDA. I am hosting multiple virtual domains with multiple users and everything is working. I would now like to create a permanent archive of all sent/received mail with each virtual user's mail saved to its own sent file and received file. This needs to be independent of the user's regular Maildir store since he can't delete or modify the permanent archive. Any suggestions on how to best accomplish this either via postfix or dovecot? Postfix has in main.cf virtual_transport = dovecot and in master.cf dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/libexec/dovecot /dovecot-lda -d ${recipient} -f ${sender} dovecot uses this: [root@xxx andrew]# dovecot -n # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.14-103.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 disable_plaintext_auth = no mail_location = maildir:/home/vmail/%d/%n/Maildir mbox_write_locks = fcntl passdb { args = scheme=plain username_format=%u /etc/postfix/passwd driver = passwd-file } protocols = imap lmtp service auth { inet_listener { port = 12345 } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 } } ssl_cert = </etc/pki/tls/certs/xxx.com.crt ssl_key = </etc/pki/tls/private/xxx.com.key userdb { args = username_format=%u uid=5000 gid=5000 home=/home/vmail/%d/%n driver = static } Thanks, Andrew

[Dovecot] mail_max_userip_connections=10
by Tom Clark 12 Dec '11

12 Dec '11

Hi, A couple of questions rather than a problem for once! We've got our Dovecot server running smoothly now apart from our MD. He's having problems with mail_max_userip_connections. He has 3 (Phone/Laptop/Tablet) items that all connect to the server at about the same time. Which means he's frequently running over the max_userip_connections. My questions are: Is there anyway of whitelisting an IP so that it can ignore mail_max_userip_connections=10? What should we set mail_max_userip_connections too realistically? 10 seems a bit low? Thanks Tom

[Dovecot] question regarding postfixadmin
by oni-neko＠gmx.net 12 Dec '11

12 Dec '11

Hello! I hope someone here is already using postfixadmin with dovecot and can help me out =) the install-readme for postfixadmin mentions, that the mail-home should be set to default_mail_env = maildir:/var/mail/vmail/%u/ but my dovecot is already installed and working with another config, namely mail_location = maildir:/var/dovecotmail/%n/Maildir. Do i have to change this, or is postfixadmin able to read this or can i set this value in postfixadmin somewhere? i´d rather avoid moving all mailfolders around just because of that, and unfortunately the paths don´t really lend themself to an easy solution via symlink ^_^ thanks for any replies best regards sil -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Documentation clarifiction on mmap_disable
by Marcio Merlone 12 Dec '11

12 Dec '11

Greetings, On http://wiki.dovecot.org/MainConfig I read: "mmap_disable = no Don't use mmap() at all. This is required if you store indexes to shared filesystems (NFS or clustered filesystem). " Does that mean: 1. mmap is required when using NFS or 2. it is required to don't use mmap at all when using NFS? Sorry if this is obvious. Best regards. -- *Marcio Merlone*

[Dovecot] database failover
by Nick Edwards 12 Dec '11

12 Dec '11

Trying to get dovecot to _only_ use local copy of database, only querying another database server (same database, just replicated) if local copy is not responding, I have google fu'd a bit and found my only answer in so far as dovecot did this once upon as time, but it was only due to a dovecot bug, that has since been fixed, is that so? The wiki shows no information of failover, just load sharing, or is it an undocumented feature, or can dovecot not do failover, if not, can it be made so? Trying to cut down on network traffic, postfix does this nicely, I thought dovecot did too.
