Sa-learn-pipe.sh script modification
by Pierre Barre 01 Nov '14

01 Nov '14

Hello, I've seen on this wiki page: http://wiki2.dovecot.org/Plugins/Antispam A script called "sa-learn-pipe.sh". I've tested it but it slow things down because dovecot wait for the script termination. So, I've made a modification. Now, the task is running in the background and dovecot move the mail without waiting for the script termination: #!/bin/bash echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log #echo $* > /tmp/sendmail-parms.txt cat<&0 >> /tmp/sendmail-msg-$$.txt /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt && rm -f /tmp/sendmail-msg-$$.txt & echo "$$-end" >> /tmp/sa-learn-pipe.log exit 0 I want know if this can cause any problem ? Thanks. -- Best regards, Pierre Barre.

Corrupted SSL parameters file in state_dir with HG 267bca7a62fb
by Thomas Leuxner 01 Nov '14

Hi, with the latest HG 267bca7a62fb the following error started to appear in the logs: Oct 31 09:39:07 nihlus dovecot: master: Dovecot v2.2.15 (267bca7a62fb) starting up for imap, lmtp [...] Oct 31 10:10:52 nihlus dovecot: lmtp(20876): Error: Corrupted SSL parameters file in state_dir: ssl-parameters.dat - disabling SSL 360 Oct 31 10:10:52 nihlus dovecot: lmtp(20876): Error: Couldn't initialize SSL parameters, disabling SSL Oct 31 10:10:52 nihlus dovecot: lmtp(20876): Connect from local This most likely has been introduced with a commit after the previous build installed (aa5dde56424f). I did not find options to disable SSL for LMTP either, as in my setup I'm using a UNIX socket. Regards Thomas

SSLv3 attack on pop3?
by Hans Morten Kind 31 Oct '14

31 Oct '14

We turned off SSLv3 support on our pop/imap running dovecot on Oct 16th, we did check that all users where using TLSv1 and there have been no complaints (except one old windows-phone). But at 13:00 UTC today, suddenly strange entries is seen in the logfile: Error: SSL: Stacked error: error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3 alert unexpected message: SSL alert number 10 Followed by: pop3-login: Disconnected (no auth attempts in 2 secs) user=<>, rip= Some 20 ips have been seen so far, all ips are uniq and none have used our server lately. Just one resoved and it's name ends .cn, some lookups with whois leads to the same origin for all. This makes me anxious that some have made some poodle-like thing for pop3? hmk

vpopmail, open_smtp_relay and non-PLAIN auth mechs
by Jim Jagielski 31 Oct '14

31 Oct '14

I've noticed that if using the vpopmail auth setup, that the roaming-user functionality provided via open_smtp_relay() is only done if the auth mechanism is PLAIN. For example, if the client authenticates via DIGEST-MD5, the open relay file is not updated, as it should be. This is due to the call to open_smtp_relay only being done via vpopmail_verify_plain(). Instead, imo, that call should be done in auth_request_success() in the auth-request.c file, so that it is done however the authentication is done, as long as it is successful. Attached is a patch for 2.2.15. Let me know if attachments are not the preferred method and I'll cut/paste. tia! -- Jim Jagielski

Can someone explain this Sent thread sorting?
by Philip Rhoades 31 Oct '14

31 Oct '14

People, I attach a screen capture of my RoundCubeMail Sent box - why does the second item on the list, which is a separate reply to the thread above it, get sorted to position 2? By the date, and being a single mail, it should be much further down the screen . . I presume it is because the Subject is the same? Thanks, Phil. -- Philip Rhoades GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil(a)pricom.com.au

Question wrt. dovecot replicator
by Remko Lodder 30 Oct '14

30 Oct '14

Hi People, I recently setup a replication service within dovecot between two machines in different datacenters, which has the following configuration; (yes it is hashed out, because I needed to) #service replicator { # unix_listener replicator-doveadm { # mode = 0666 # } # process_min_avail = 1 #} # #service aggregator { # fifo_listener replication-notify-fifo { # mode = 0666 # #user = vmail # } # unix_listener replication-notify { # mode = 0666 # #user = vmail # } #} # #service doveadm { # inet_listener { # port = 12346 # } #} # ##doveadm_port = 12346 #doveadm_password = XXXXXXX #replication_max_conns = 30 # and a mail_replica = tcp:host{a,b}:12346 configuration on each host so that they are pointing to eachother; This seems to work fine for most accounts, for example: I never experienced issues with this. However, several other accounts (with a large variety of clients) got duplicated emails. Looking with doveadm I only noticed that the numbers of the messages are closely related to eachother but one number incremented. So they cannot be deleted with the deduplicator function. The replication is provided over TCP only, the connection streams over an OpenVPN tunnel so that the contents are protected, the machines are located in different Datacenters but close to eachother. How can I determine why there are duplicated emails? What kind of messages should I specifically look for? Can I set this up for a few selected accounts instead of all accounts like it was currently? To make sure I do not make things worse for others then needs to be :-) The service had been disabled for the time being to prevent the other users from getting duplicated emails. Thanks for the advice in advance!

different mail location in different namespace
by Héctor Moreno Blanco 30 Oct '14

30 Oct '14

Hello everyone, We have Dovecot 2.1.6. With different Namespaces: ... mail_location = maildir:%h/Maildir ... namespace { separator = . prefix = inbox = yes type = private } namespace { inbox = no location = prefix = INBOX. separator = . hidden = yes type = private list = no } namespace { location = maildir:/buzon/archivo/%u/_ARCHIVO prefix = _ARCHIVO. hidden = yes separator = . type = private } We take the attribute "home directory" from the LDAP in the userdb attributes. We would like to modify this attribute for the Namespace ARCHIVO. For example, if a home directory is /buzon/buzon1/11111111, the mail location for ARCHIVO would be /buzon/archivo1/11111111. Is this modification possible without adding another attribute at the LDAP (just editing the attribute)? Thank you very much in advanced. Kind regards. Héctor Moreno.

Bug in the combination of Lazy_expunge and acl plugin
by Philipp Faeustlin 30 Oct '14

30 Oct '14

Hello Timo, Hello Dovecot Developers, Hello everyone on the list, I think I have some bug, because I haven't found a working configuration till now. I use latest dovecot 2.2.13 from the dovecot-ee repository, with acl and the lazy_expunge plugin. My configuration for shared folders work fine with lazy_expunge disabled. If I enable lazy_expunge and the user (named userA), which I'm testing with, got no shared folders, then lazy_expunge is working as supposed. Now I add some shared folder for example per doveadm: doveadm acl set -u userB(a)domain.de INBOX user=userA(a)domain.de lookup read write write-seen write-deleted insert expunge create After that every list command fails with: Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' '.EXPUNGED/' is the name for the namespace of lazy_expunge. Easiest way for me to reproduce the error is: doveadm mailbox list -u userA(a)domain.de which results in: ----------------- Trash Drafts Sent doveadm(userA(a)domian.de): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' ------------------ I hope someone can confirm this behavior and or give me some hints to get rid of it. Regards Philipp Fäustlin

Bug in fts (solr?, Maildir?) incorrect last_indexed_uid
by Karl O. Pinc 30 Oct '14

30 Oct '14

Hi, I thought I should document this. (Dovecot 2.2.9, see config at bottom.) I installed dovecot and then converted a number of mbox mailboxes to Maildir, and had a number of pre-existing Maildir mailboxes. I then installed the debian (wheezy) fts-solar and jetty packages, and tested my inbox using the "telnet localhost imap ... 3 SEARCH text "test" method as described on the dovecot wiki. Everything seemed to work. But when I used balsa to search a mailbox other than my inbox, I got no results. "doveadm dump" on the searched mailbox showed that "last_indexed_uid" to be the last uid of my inbox. Stopping dovecot, deleting out the dovecot-index* files, starting dovecot, and re-running "doveadm dump" showed a non-existant last_indexed_uid -- that is, last_indexed_uid did not show up in the dump output. Using the telnet method above to attempt to search again yielded no results, but this time (I think, I also tried various times with balsa) the last_indexed_uid value was that of the last uid in my trash mailbox. I don't believe I'd yet tried fts on my trash. Using balsa as an imap client the results were very consistent; every Maildir where "doveadm dump" returned no last_indexed_uid value had the last_indexed_uid set to that of the inbox's largest uid. Running "doveadm fts rescan -u foo" fixed the problem. (FWIW, now all the Maildirs seem to have a last_indexed_uid=0.)
