[Dovecot] Sieve problems (not matching emails expected to match)
by Michael Welsh Duggan 21 Mar '11

21 Mar '11

I have a sieve file that reads like this: require "fileinto"; # Emacs if header :contains "List-Id" "emacs-devel.gnu.org" { fileinto "mail.emacs-devel"; } elsif header :contains "List-Id" "emacs-bidi.gnu.org" { fileinto "mail.emacs-bidi"; } ... Unfortunately the List-Id based lines don't appear to be working, although some other ones do. The attached test message does not get delivered to the mail.emacs-devel list. Why? -- Michael Welsh Duggan (md5i(a)md5i.com)

[Dovecot] dovecot authentication Local + MySQL
by PARTH MONGA 20 Mar '11

20 Mar '11

Hi Friends I am facing an issue with dovecot configuration and i am describing it in a nutshell. We have a dovecot setup under ultramonkey load balancer and in loadbalancer we have a check defined for pop service which queries mysqldatabase for a particular user name/password after every 2 minutes to check if service is live or not.. Things are fine till here . Now The catch is if somehow that particular user info(either password or username) is mistakenly changed in mysql database whole of my pop gets down beacuse load balancer cant login and that is a single point of failure in my setup . Now what i want is I want to know if there is any method that i can setup in dovecot to lookup for a user locally first and then go for a remote search for the user( ie in mysql database) So that we get the user searched locally before querying the mysql database Local + mysql database authetication i want to be in parallel with each other. Please show some light on this . Thanks and Regards Parth Monga

[Dovecot] Strange Dovecot Issue
by Scott Hughes 20 Mar '11

20 Mar '11

Greetings, I am trying to copy email from one server to another server using Thunderbird. The old server is a closed source ModusMail server and the new server is a Qmail server running Dovecot 1.2.3 (yes, I realize this is behind the times a bit). My issue is this: Whenever Thunderbird gets to a message that has been forwarded (has the forward flag set) an error is generated from the new server (dovecot) that it does not know how to handle the forward flag. Is this a known issue or is it simply that my version of Dovecot is behind? Thanks, Scott

[Dovecot] Question about "extracting" unwanted e-mails from mdbox
by Maria Arrea 20 Mar '11

20 Mar '11

Imagine the following scenario Last Saturday, 3:00 AM a big phishing attack hits our e-mail inboxes. Spamassassin does not mark them as spam, and our 50.000+ users have in their mdbox a very credible phishing attack. What doveadm-fu could I use to delete (or move to spam) that e-mail from each user INBOX (let´s imagine the Subject or a Header is known)? I repeat: already delivered e-mail, how to filter/prune it. Regards Maria

[Dovecot] remove old files
by Stéphane Guedon 20 Mar '11

20 Mar '11

Hello I use the dovecot 2.0.10 server and wonder how to clean up correctly the old mails (especially for spam folder). I use maildir storage, and wonder if deleting files with an rm and file command combinaison would be good or would corrupt indexes files/whatever. for exemple, the spam folder is in ~/.mail/.INBOX.spam/ Thus, can I "cd ~/.mail/.INBOX.spam/ && rm 'files older than 2 months' " or something else ?

Re: [Dovecot] Problem with expire plugin and expunge

Hello, > > Big surprise: Something bad must have happened after the messages were > > deleted from Trash; now all messages are zero days old. > > Are you using maildir? Did you run with those patches + mail_debug=yes? Today, the daily cronjob expired some messages. I have attached the output of the job. It seems that the error occurs not when expunging, but when deleting the first message after expunging. Before deleting a message, "doveadm search" showed me messages that were between zero and four days old, but directly after deleting a message, all messages were zero days old. Here is my log entry from when I deleted that message: Mar 18 09:50:28 joseph dovecot: imap(christoph): Debug: expire: Saving first message to Trash, updating timestamp to 1300438228 Regards Christoph

[Dovecot] dovecot LDA: "temporary failure"
by David Koski 18 Mar '11

18 Mar '11

This really has me stumped and desperate. I upgraded Debian from 5 to 6 (squeeze) and now Dovecot LDA fails. I have checked permissions and the usual. Postfix SMTP, Dovecot POP3 and Dovecot IMAP work. Having to upgrade MySQL from 5.0 to 5.1 made me question that. Logging is of little help. I have turned on logging for LDA to a separate file. When I try to run the deliver command it returns nothing and appears to do nothing: ~$ cat /etc/hosts | /usr/lib/dovecot/deliver -f root@localhost -d dkoski(a)[domainhidden].com $ ..but then I don't know what to expect. The log files are owned by dovecot. I tried chmod'ing them to 777 in desperation. This was working before the upgrade to 1.2.15-4 from 1.0.15-2.3+lenny1. Postfix reports this stuff: Mar 17 22:37:38 host-mail postfix/smtpd[22160]: connect from mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:39 host-mail postfix/smtpd[22160]: 9D80C12AF610: client=mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:39 host-mail postfix/cleanup[22163]: 9D80C12AF610: message-id=<201103172237.29223.dkoski(a)[another-domainhidden].com> Mar 17 22:37:39 host-mail postfix/qmgr[21877]: 9D80C12AF610: from=<dkoski(a)[another-domainhidden].com>, size=1257, nrcpt=1 (queue active) Mar 17 22:37:39 host-mail postfix/smtpd[22160]: disconnect from mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:42 host-mail postfix/smtpd[22168]: connect from localhost[127.0.0.1] Mar 17 22:37:42 host-mail postfix/smtpd[22168]: 480D912AF612: client=mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:42 host-mail postfix/cleanup[22163]: 480D912AF612: message-id=<201103172237.29223.dkoski(a)[another-domainhidden].com> Mar 17 22:37:42 host-mail postfix/qmgr[21877]: 480D912AF612: from=<dkoski(a)[another-domainhidden].com>, size=1873, nrcpt=1 (queue active) Mar 17 22:37:42 host-mail postfix/smtpd[22168]: disconnect from localhost[127.0.0.1] Mar 17 22:37:42 host-mail postfix/pipe[22169]: 480D912AF612: to=<dkoski(a)[domainhidden].com>, relay=dovecot, delay=0.04, delays=0.02/0.01/0/0.01, dsn=4.3.0, status=deferred (temporary failure) Mar 17 22:37:42 host-mail postfix/smtp[22164]: 9D80C12AF610: to=<dkoski(a)[domainhidden].com>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.4, delays=0.84/0.01/0/2.5, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=11197-13, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 480D912AF612) Mar 17 22:37:42 host-mail postfix/qmgr[21877]: 9D80C12AF610: removed And /var/log/dovecot/deliver.info: 2011-03-17 22:43:43 auth(default): Info: new auth connection: pid=22232 2011-03-17 22:43:59 auth-worker(default): Info: sql(dkoski(a)[domainhidden].com,127.0.0.1): query: SELECT email as user, password FROM view_users WHERE email='dkoski(a)[domainhidden].com'; 2011-03-17 22:43:59 auth(default): Info: client out: OK 1 user=dkoski(a)[domainhidden].com 2011-03-17 22:43:59 auth(default): Info: master in: REQUEST 73 22061 1 2011-03-17 22:43:59 auth(default): Info: master out: USER 73 dkoski(a)[domainhidden].com uid=5000 gid=5000 home=/home/vmail/[domainhidden].com/dkoski 2011-03-17 22:44:00 auth(default): Info: new auth connection: pid=22234 I tried reinstalling the package dovecot-common.

[Dovecot] Migrating to mdbox
by Chris Wilson 17 Mar '11

17 Mar '11

Hi all, I think it would be a good idea for me to move from mbox to mdbox, as I have 57,000 messages in my inbox, and clients hang for a minute whenever they request a CHECK, or Dovecot feels the need to run one itself. Looking at past threads: http://www.mail-archive.com/dovecot@dovecot.org/msg35212.html http://comments.gmane.org/gmane.mail.imap.dovecot/53936 it seems that the safest way is to run: sudo dsync -v -u chris backup mdbox:/home/chris/mdbox eliminate any errors that it reports, test the new mdbox access temporarily, and then switch my config in Dovecot. Ideally I'd like to do that just for me, without disrupting other users of this server (that I help to admin). This error occurs every time I run dsync, and I understand it, so I've elided it: dsync(chris): Error: open() failed with mbox file /home/chris/mail/admin: Permission denied dsync(chris): Error: Failed to sync mailbox admin: Internal error occurred.

17 Mar '11

Getting ready to redo our mail server setup and I'm trying to wrap my head around the ins and outs and pratfalls involved in SSL, multiple domains, and Dovecot. I've taken a look at: http://wiki2.dovecot.org/SSL/DovecotConfiguration My basic understanding at this point is that: - With SSL for IMAP/POP3, it is limited to one certificate per IP address, because the SSL process starts as soon as the client opens the socket to the IP address. In order to support multiple domains / server names, you have to rely on SAN (Subject Alternative Names) in the server's SSL certificate. - If I use STARTTLS for IMAP/POP3 and Dovecot 2.x, then the SNI process will allow the client to specify that they want to talk to mail server XYZ and Dovecot will hand the correct certificate to the client. However, a lot of devices don't support SNI yet so this is fraught with peril and incompatibilities. So it seems like if I have fewer IP addresses then mail server names, I should stick with a single SSL cert and use SANs. (Wildcard certs are not an option due to the top level domain being different.) How big of an issue is a cert with half a dozen or a dozen SANs attached? Do most mail clients handle that sort of certificate properly in order to access their mailboxes? Reference links: http://www.digicert.com/subject-alternative-name-compatibility.htm

[Dovecot] problems with public (sub)folders

Hi, i am trying to share a maildir++ mailbox to other users but i can only subscribe to the root directory. The subfolders of the public mailbox do not appear in the exported list. Does anyone has an idea how i can share the subfolders too without creating symlinks for every single folder?

[Dovecot] dict crashes with multiple map definitions
by Birger Brunswiek 17 Mar '11

17 Mar '11

Hi, I get a crash in dict if I use multiple map sections. Each one of them works fine by their own. I managed to convince dovecot to create dump files to debug this, but I can't figure out how to do the same for dict. How can I do this? Anyway, perhaps someone already know's what's wrong by looking at what I do in the sql dict configuration.

[Dovecot] dovecot 1.2 quota with local users
by iti＠promax.media.pl 17 Mar '11

17 Mar '11

Hello, I got problem with setting quota from mysql for local users. In database are only information with quota. Password are store in passwd/shadow. My database have only simple info like in wiki description. Table created with: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 0, messages integer not null default 0, primary key (username) ); In dovecot.conf like in description is: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { # v1.2 + SQL: quota = dict:user::proxy::quotadict # v1.2 + file: quota = dict:user::file:%h/Maildir/dovecot-quota quota_rule = *:storage=10M:messages=1000 } File dovecot-dict-sql.conf has: # v1.2+ only: connect = host=localhost dbname=mails user=sqluser password=sqlpass map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } With corrected values about databasename, user and password. Where should to add information about sql query when autorization is not via myqsl (only shadow/password). There are in description info about additional file with user_query: dovecot-mysql.conf. Can anybody know how it should it look like and where to add it in config?

[Dovecot] inetd config - dovecot doesn't exits

Is there any option for dovecot to exit when is unneded? I mostly use dovecot via shell process (ie. something like /usr/sbin/dovecot --exec-mail imap) But sometimes I want to use it remotely via tcp and I run dovecot via inetd. --8<---------------cut here---------------start------------->8--- localhost:imap stream tcp nowait root /usr/sbin/tcpd /usr/lib/dovecot/imap-login --8<---------------cut here---------------end--------------->8--- in inetd.conf works good, but dovecot stays, even if all clients ended their connections. How can I make dovecot to exit after last client disconnects?

[Dovecot] Attachment file size error in SIS
by Daniel L. Miller 17 Mar '11

17 Mar '11

I've got an attachment that triggers a "smaller than expected" error. It was a pdf I received some time ago. I copied the file from the dovecot storage, renamed it to something close to the original name (I don't remember what that was), then created a new mail with this as an attachment and saved it to the server. This created a new file, identical file size to the other - but continues to have the "smaller than expected" error. -- Daniel
