sieve and antispam
by Andrew McN 17 Aug '15

17 Aug '15

I have a fairly standard antispam/dspam setup: postfix delivers to dspam, which classifies and tags the mail, and then passes it to postfix which uses sieve to put mail into the appropriate folders based on dspam's classification. I also have the antispam plugin watching mail being moved between folders and re-training dpsam accordingly. If I now add some sieve filter rules which put incoming mail into appropriate folders, possibly overriding what would normally result from dspam's classification, will that be seen by the antispam plugin and used for training dspam?

Hi, I want to say hello and here is my big problem ;D Iam trying to archive a Postfix/Dovecot 2.2.10 CentOS7 Multidomain Setup with multiple (valid StartSSL Certs), but iam only able to run a single Domain Cert server only. ps: I need a multiple domainssetup for every customer and it is not an option for me redirecting any email to a single domain server.

ipv4 imap not accepting connections in mixed ipv4/ipv6
by djk 15 Aug '15

15 Aug '15

I have two installations of dovecot 2.18, apart from the necessary changes to allow them to replicate amongst themselves the configs are identical. Both are running Ubuntu 14.04 and are kept up to date. One is running 64bit and the other 32 bit (for historical reasons). Both have ipv4 and ipv6 addresses. The 64 bit installation allows access on port 143 and 993 on both ipv4 and ipv6. The 32 bit installation does not allow access on 143 on ipv4, but allows ipv4/ipv6 on 993. Both installations happily allow connections to any other ports that dovecot might be using on both ipv4/ipv6, as well as everything else that is running (on other ports) on those machines. There are firewalls, but no warning messages. Switching firewalls off makes no difference. Tcpdump shows the SYN packets arriving on the (correct) interface. Any suggestions? Dirk

IMAP folder separator issue
by Alex 15 Aug '15

15 Aug '15

Hi, I'm using dovecot-2.2.18 on fedora22 and having a problem with Thunderbird. I reported this problem some time ago, and received some tips, but no solution that's worked. I'm now trying to fix this in earnest, and having problems. The problem is sub-folders are created with a caret in them, instead of a new folder below the parent folder. So instead of folder/sub-folder, folder^sub-folder is created. I'm using mbox folders, and it worked under previous versions of fedora and dovecot. I believe it has to do with the separator character that's used, based on this wiki page: http://wiki2.dovecot.org/Plugins/Listescape The problem is that those instructions cause errors: Aug 14 20:00:01 orion dovecot: pop3(cerberus): Error: User initialization failed: namespace configuration error: Duplicate namespace prefix: "" Aug 14 20:00:01 orion dovecot: pop3(cerberus): Error: Invalid user settings. Refer to server log for more information. I've also had to change the "namespace private" to "namespace { type=private }" as that's apparently a deprecated syntax. Perhaps there's an updated page with more instruction and correct information? I'm unsure where this duplicate namespace is that it's talking about... I've included my doveconf output below, in hopes someone can help. I should also point out that "separator = $" is quoted in the original doveconf.conf but apparently doveconf doesn't properly print it. # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.0.7-300.fc22.x86_64 x86_64 Fedora release 22 (Twenty Two) default_client_limit = 2000 mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_plugins = " listescape" mail_privileged_group = mail mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = $ type = private } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 } process_min_avail = 20 service_count = 0 } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { address = 192.168.1.100 port = 995 } } ssl_ca = </etc/pki/dovecot/certs/ca-bundle.pem ssl_cert = </etc/pki/dovecot/certs/orion-2015.pem ssl_key = </etc/pki/dovecot/certs/orion-2015.key userdb { driver = passwd } userdb { driver = passwd }

backing up email / saving maildir on external hard drives
by Kevin Laurie 15 Aug '15

15 Aug '15

Hello, Yesterday I tried to back up a 40GB maildir . I tried to move the maildir from home to external HDD but failed. Decided then to compress it(which took several hours). Now changing the disk format from FAT to exFAT to allow the transfer for the large compressed file. How does one back up emails on a external drive? Some advice would be greatly appreciated.

need help debugging deleted mails
by Vu Ngoc VU 13 Aug '15

13 Aug '15

hello, one of our users complained about the fact that he doesn't receive some messages (randomly) that his teamates have. Grepping for the message-ID in the mail.log, I can see lmtp says it is saved : Aug 12 15:23:23 imap-01 dovecot: lmtp(4943, johndoe(a)example.net) fFuCO09Hy1VPEwAA2t/0+w: sieve: vsize= msgid=<037e01d0d502$0e3687d0$2aa39770$(a)example.net>: stored mail into mailbox 'INBOX' The only difference with others recipients is the 'sieve:... stored mail' instead of 'saved mail to' when there is no sieve. But when he asked me, the message was no more in his maildir (I checked with doveadm search). As we have checked and disabled all the filters in his MUA and on the server (sieve) and this issue still continue, I did mkdir a dovecot.rawlog inside his home. With the help of rawlog, I can see that the message can be found in a .out file (by grepping the Message-ID). And by reading this .out log raw log, the entire message were sent to the client. So I guess that : * the message was written to disk * it was sent to the MUA But I need your help because I don't get how this message disappear from his maildir. My assumptions was that the client must do some commands like : * STORE the \Deleted flag to this message UID * and then, later do EXPUNGE but I did : * grep -i expunge * 20150812* => no match * grep -iE '\+flags .*\\deleted' => a few matches but not with the appropriate UID snippet from the 20150812-133858-13317.in file: 8nk1 UID FETCH 208209 (UID FLAGS RFC822.SIZE BODY.PEEK[HEADER] INTERNALDATE) p7uv IDLE DONE 6yk3 NOOP 83g6 IDLE DONE yhbd UID FETCH 208209 (UID FLAGS BODY.PEEK[]) fy16 IDLE DONE snippet from the 20150812-133858-13317.out file: * 56295 FETCH (UID 208209) wn2p OK Fetch completed. * 56295 FETCH (UID 208209 FLAGS (\Deleted \Seen \Recent) RFC822.SIZE 17138 INTERNALDATE "12-Aug-2015 15:23:22 +0200" BODY[HEADER] {2836} Considering these points: * I cannot find any match with 208209 early in raw logs * I don't see any expunge for the whole day * I've grepped for \Deleted (insensitive) and didn't find matching like a interval of messages UID. What did I miss to find out how/when the message got \Deleted flag and was removed from his maildir? A few about my setup : * system is ubuntu 14.04 inside OpenVZ containers (Proxmox) * dovecot version is 2.2.9 from Ubuntu packages * 2 director with Internet and local ip addresses * 2 backends with only local addresses * these dovecot access storage servers by NFSv3 (that's why we have director) * imap/lmtp are proxied Thanks a lot for reading, I'm really disappointed about this problem. For the moment, I'll delete his script even if all rules are disabled (via roundcube, and I checked the rule is commented in the file). And also I'll try to watch what happens with inotify on the storage server.

Hi, I am trying to back up my IMAP server to a hard drive. Later I intend to extract all mails for attachments. What do you reckon is the best too to perform this ? Imapsync or Thunderbird (or something else, please recommend) One problem I am having with imapsync is the setting for host2 (being a localhost computer). How does one set a parameter for host2 being a desktop computer. Thanks Kevin

userdb / user map with director
by Will Yardley 10 Aug '15

10 Aug '15

This is with dovecot-ee 2.2.18.2 on RHEL6.... To handle backend and frontend on same machine, I'm using the following hack, as previously outlined here: [in director instance config] passdb { # See thread ending in: # http://dovecot.org/pipermail/dovecot/2012-June/083817.html # for why this has to be sql instead of 'static' driver = sql args = /etc/dovecot/dovecot-sql.conf } [in /etc/dovecot/dovecot-sql.conf] driver = sqlite connect = /etc/dovecot/empty.db password_query = select 'y' as proxy, \ NULL as password, \ 'y' as nopassword, \ case '%a' \ when '110' then '10110' \ when '995' then '10110' \ when '143' then '10143' \ when '993' then '10143' end \ as port; This works, but I was getting a failure on usernames, since director instance didn't have a userdb. So I tried the following: [in config] passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } and appended the following to the SQL query: password_query = select '%u' AS user, \ Then I see the following error in the log when I try to run the map "Trying to iterate users, but userdbs don't support it" and doveadm -i director director map returns: Error: User listing returned failure Error: user listing failed [...] I'm sure I'm missing something obvious, so is there an easy fix to make this mapping work? w

Dovecot sends "OK Logged in" with empty tag
by Simon Thelen 10 Aug '15

10 Aug '15

Hello, I'm currently writing my own IMAP client and testing it against Dovecot, and when doing PLAIN AUTH Dovecot sends the "OK Logged in" with an empty tag at the start. I tried reproducing the conversation with netcat, but Dovecot sends a correctly tagged OK at the end of the AUTH so I assume it's timing related. I've attached pcap dumps of the TCP conversation in both situations as well as the output of dovecot -n. Side Note: Why does Dovecot send the updated capabilities before OK'ing the authentication? Seems strange to me as the client can't assume that the authentication proceeded successfully until it actually receives the OK so it has to assume that those capabilities are pre login. -- Simon Thelen

Using a separate passdb per service
by Gerry 10 Aug '15

10 Aug '15

Situation: one front-facing server running Dovecot as IMAP/POP3/ ManageSieve proxy, a mixture of IMAP servers (Dovecot, Exchange, ...) in the back-end. Dovecot's passdb does lookups against MySQL which contains a simple user/host mapping, the actual authentication happens on the back-end IMAP servers. The configuration is more or less as described here: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy Now I would like to add a Postfix instance on the front-facing server which listens on the submission port and authenticates users via SASL using the local Dovecot's UNIX socket. The idea being that a user only needs to remember one single hostname, one username and one password for all mail-related services. The problem is that Dovecot is operating in proxy mode, which means that the password_query returns NULL as the password and explicitly returns a field "nopasswd" containing "Y". Thus, users can not authenticate against the UNIX socket. What I think I want to do is convince Dovecot to use one passdb for the imap/pop3/managesieve services and different one for the "auth" service. The configuration snippet below doesn't work, but it should illustrate what I want to achieve: > protocols = imap pop3 sieve > > service auth { > passdb sql { > driver = sql > args = /etc/dovecot/mysql-auth-sasl.conf.ext > } > > unix_listener /var/spool/postfix/private/auth { > user = postfix > group = postfix > mode = 0666 > } > } > > # IMAP/POP3/ManageSieve auth against MySQL > passdb sql { > driver = sql > args = /etc/dovecot/mysql-auth-default.conf.ext > } Example mysql-auth-sasl.conf.ext > driver = mysql > connect = host=127.0.0.1 dbname=mail user=mail password=somethingrandom > password_query = SELECT password AS password FROM users WHERE login = '%u' Example mysql-auth-default.conf.ext: > driver = mysql > connect = host=127.0.0.1 dbname=mail user=mail password=somethingrandom > password_query = SELECT NULL AS password, 'Y' as nopassword, host, 'Y' AS proxy FROM users WHERE login = '%u' Any pointers?

I am using maildir as a mail storage format and currently have the following setting on my local machine :- mail_location = maildir:~/Maildir I am afraid that if I imapsync multiple accounts they will all get stored in the same location. Is there a way to seperate the accounts based on the email address? Appreciate if someone could advise. Thanks! Kevin

Example: user+extenstion will be delivered to the user and subfolder extenstion so this is okay. but user+extenstion will not be delivert to the user and exiting subfolder Extenstion so that is not okay. The mail will be also delivered in the subfolder extension. The exiting Folder Extension will not used. Give's a way to tell dovecot, use the extension as a Folder, if a exiting folder with Upper/Lower Cases will be detect and use the right folder to delivery? -- Regards Sascha --- Diese E-Mail wurde von Avast Antivirus-Software auf Viren geprüft. https://www.avast.com/antivirus

Dovecot/Pigeonhole Issue (UTC modtime instead of localtime)
by Christoph Gröver 06 Aug '15

06 Aug '15

Hi List, We are using the following setup: Dovecot-2.2.18 Pigeonhole-0.4.8 (for Dovecot-2.2) After the mail is finally delivered via a fileinto by the Sieve filter it gets an updated timestamp (modification time). The server has localtime setup correctly IMO (UTC +0200), but still the delivered mail is setup as being two hours old. I think I found out that the function sieve_file_storage_update_mtime() is the cause of this problem. But perhaps there has to be some kind of setup, that tells pigeonhole to use the 2 hour offset of CEST. I think to reset the mtime by utime(s) is a bit strange. It already gets the correct modtime just by storing it in the filesystem. Last version we used (0.2.5) did not have this poblem. So it must be there for some reason? Perhaps you can enlighten me. Thanks for your time.

Dovecot sieve pigeonhole permission
by Gerhard Wiesinger 05 Aug '15

Hello, I'm running dovecot in a classical vmail.vmail setup with pigeonhole and LMTP. Permission worked well in the initial setup but currently (maybe after Fedora 22 update) I'm having the following permission issue: lmtp(root): Error: 7fPZFOL9wFXePQAABcdabc: sieve: binary open: failed to open: open(/etc/dovecot/sieve_after.svbin) failed: Permission denied (euid=9999(vmail) egid=9999(vmail) missing +r perm: /etc/dovecot/sieve_after.svbin, we're not in group 0(root), dir owned by 0:0 mode=0755) lmtp(root): Error: 7fPZFOL9wFXePQAABcdabc: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve_after.svbin.myserver.mydomain.15838.) failed: Permission denied (euid=9999(vmail) egid=9999(vmail) missing +w perm: /etc/dovecot, dir owned by 0:0 mode=0755) lmtp(root): Error: 7fPZFOL9wFXePQAABcdcbc: sieve: The LDA Sieve plugin does not have permission to save global Sieve script binaries; global Sieve scripts like `/etc/dovecot/sieve_after.sieve' need to be pre-compiled using the sievec tool rpm -V dovecot dovecot-pigeonhole doesn't report any permission issues Versions: dovecot-2.2.18-2.fc22.x86_64 dovecot-pigeonhole-2.2.18-2.fc22.x86_64 Relevant config parts: mail_gid = vmail mail_uid = vmail plugin { sieve = ~/.dovecot.sieve sieve_after = /etc/dovecot/sieve_after.sieve sieve_dir = ~/sieve } ls -lad /etc/dovecot/ drwxr-xr-x. 3 root root 4096 Jul 30 18:13 /etc/dovecot/ ls -la /etc/dovecot/*sieve* -rwxr-x--- 1 vmail vmail 288 Aug 8 2014 /etc/dovecot/sieve_after.sieve -rw-r----- 1 root root 355 Jul 30 18:13 /etc/dovecot/sieve_after.svbin What's are the recommended permissions for the files/directories (also for root service startup of dovecot)?

Renaming shared mailbox makes it disappear from sharee
by Andy Csillag 03 Aug '15

03 Aug '15

I've run into an interesting thing. If a mailbox has been shared to a second user (I'll call it the sharee), and there are subfolders on that mailbox, and the sharee renames one of those subfolders, it disappears from view to the sharee. The only way I've been able discover to fix it is to have the sharee create a new subfolder -- then the renamed folder shows up again; in addition to the newly created folder. For example, first(a)example.org shares it's INBOX to second(a)example.org. There's a folder INBOX/thing, which second@ renames to INBOX/renamed (ACLs permitting). second@ can no longer can see INBOX/renamed (or INBOX/thing for that matter), via IMAP's LIST command. But if second@ creates a new folder INBOX/other, INBOX/renamed is now visible. This is very reproducible for me. I also tried it without the imappostlogin bit (in the dovecot -n). Anyone else run into this? No NFS is involved, this is a single machine setup.

Structure of dovecot.index.pvt.log
by Miloslav Hůla 03 Aug '15

03 Aug '15

Hi, we are migrating from Cyrus to Dovecot and I would like to migrate seen flags for shared folder too. We have Dovecot 2.2.13 prepared as: location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n Now I'm looking for 'dovecot.index.pvt.log' syntax to be able migrate Seen flags. All I know is, that index contains messages UID and Seen flag. May I ask you for a link to doc (if it exists) or into a source code? Should I care about 'dovecot.index.pvt.log' timestamps? Thank you, Milo

Question RE listescape and separators
by Jakob Curdes 30 Jul '15

30 Jul '15

Hello, we just start moving a large number of mailboxes to a new dovecot server with dovecot 2.0.9 (from CentOS) and sdbox as mailbox type. We use imapsync so there is no issue with mailbox type conversion. However, in test runs I noted that some mail folders,e.g. with dots in them, could not be transferred; dovecot says Couldn't create folder [7.8) Personnel] from [7.8) Personnel]: 106 NO Character not allowed in mailbox name: '.' We have the separator "/" defined for our only namespace so the dot should not be an issue!? I tried to use listescape but either the plugin is not loading (how can I verify this?) or it does not escape the dot in the mailbox name. The listescape settings are the defaults: namespace { separator = / (...) } mail_plugins = $mail_plugins listescape plugin { listescape_char = "\\" } What am I doing wrong? How can I make dots in mailboxes possible? Best regards, Jakob Curdes

Hello Sascha, sieve scripts are quite easy, see Steffen's example. I think what you want your script to do is: With any detail part, lowercase it, file message into detail folder, create as necessary. Something like auto-variables in Makfiles, where the rule gets its value from the target, e.g. -- peter
