how to mass delete after a hacked mail?
by voytek＠sbt.net.au 17 Sep '16

17 Sep '16

I had a hacked user account resulting in several thousand bounces back to that email inbox, account now corrected, but, how can I mass delete bounces with say subject like: "Undelivered Mail Returned to Sender" (by from ? ""Mail Delivery System" <MAILER-DAEMON(a)emu.sbt.net.au>") or what other ways to clean the mess ? thanks, V

converting maildir to mailbox
by Anton Yuzhaninov 16 Sep '16

16 Sep '16

Hi all! There is a script to convert maildir to mailbox in wiki: http://wiki.dovecot.org/Migration/MailFormat but it doesn't convert any message flags (seen e.t.c.). I wrote a script, which converts most flags and labels: https://bitbucket.org/citrin/scripts/src/tip/dovecot-maildir2mbox.pl It doesn't convert recent flag and UIDs though, because it was not necessary in my case. Do you think link to the script should be added to dovecot wiki? -- WBR, Anton Yuzhaninov P. S. My use case was: get maildir from other server, convert to mbox, compress (gzip -9) and add to my mailbox as read-only archive.

pop3 deleted count
by Dave 16 Sep '16

16 Sep '16

On pop3 logout, we're seeing log lines where the deleted count is blank (using default pop3_logout_format), so "del=%d/%m" is displaying in the logs as: "del=/1186" for example. In src/pop3/pop3-client.c:552: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : 0; Shouldn't this be: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : "0"; (very minor bug) -- Dave

How to obtain a "non-stripped" executable for producing a usable core-dump
by Ben Johnson 14 Sep '16

14 Sep '16

Hello, I'm attempting to capture a core-dump file, and gdb reports warning: core file may not match specified executable file. And only after installing "dovecot-dbg" on my system (Ubuntu 16.04 LTS) does gdb report further warning: the debug information found in "/lib64/ld-2.23.so" does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch). It took some searching the internet to realize that both messages are likely the result of having a "stripped" executable: # file /usr/lib/dovecot/dovecot-lda /usr/lib/dovecot/dovecot-lda: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=49c9c607c304a5c853c05a4ccb9e4b995f185ac4, stripped So, how best I am I to obtain a "non-stripped" dovecot-lda executable? Must I forego my distro's repositories and download the dovecot source, compiling every executable and all plugins "from scratch", in order to obtain a useful core-dump file? Perhaps the bug report instructions at http://www.dovecot.org/bugreport.html should mention "stripped" executables and how to avoid them. Perhaps I am simply ignorant, but if that is the case, there is little to no hope for the "average user" where submitting bug reports is concerned. Any guidance would be most appreciated. Thanks in advance, -Ben

Limit replication to one user
by Arne Hoffmann 14 Sep '16

14 Sep '16

Hello, we have a setup here where the main (and only important) feature of the IMAP server is the public folder. Two Dovecot instances are running in a active/passive cluster and mailstorage should be replicated between the two. Since there is a race condition when using public namespaces (locking on user level and not on mailbox level) I had the intention of limiting the replication to one user. I read somewhere that dsync is replicating all the users the command "doveadm user '*'" shows.

Dovecot con Autentication Checkpassword error signal 111
by zerocool＠modemsoft.it 13 Sep '16

Good morning, It is the first time I write in this mailing list and I apologize in advance for possible nonsense that i can write. I have a mail server with qmail + courier imap and I would "Migrate" to dovecot. I installed the package and configured the components necessary to me using as system autentication checkpassword. I have verified the checkpassword operation without the processor usage of Dovecot and is functioning. When you perform the tests with dovecot from the logs out these errors: auth: Error: checkpassword(plutos,127.0.0.1,<WLcLPkg8esF/AAAB>): Child 15375 died with signal 11 auth: Error: checkpassword(plutos,127.0.0.1,<WLcLPkg8esF/AAAB>): Child 15376 died with signal 11 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<plutos>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured master: Warning: Killed with signal 15 (by pid=15479 uid=0 code=kill) or : auth: Error: checkpassword(plutos,192.168.1.113,<zzV561I8IuDAqAFx>): Child 15851 died with signal 11 auth: Error: checkpassword(plutos,192.168.1.113,<zzV561I8IuDAqAFx>): Child 15852 died with signal 11 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<plutos>, method=PLAIN, rip=192.168.1.113, lip=192.168.1.113, secured imap-login: Info: Disconnected: Too many invalid commands (no auth attempts in 102 secs): user=<>, rip=192.168.1.235, lip=192.168.1.113 auth: Error: checkpassword(plutos,192.168.1.235,<7pLd+FI81uXAqAHr>): Child 15870 died with signal 11 It is already a long time that we slam but I can not figure out where to make the mistake.

Re: Use of obox2 and AWS S3

Thanks Karol My challenge with AWS EFS is waiting for it to be HIPAA/BAA certified. But good to know it's a satisfactory option.

As the initial performance is bad it scales pretty quickly with space used. So it handles maildir storage very well. The latency is a little high but with indexes there is no problem. It works as NFS storage with unlimited space (8EB) and you pay for what you use. So it turns out to be very cost effective as you do not have to worry about reserving space. For better performance you can keep indexes on ephermal storage or EBS, which both have much lower access times. As for 'elastic cloud type hosting' EFS store can be used by thousands of instances in multiple AWS AZs at the same time, so it looks like it is somehow optimized.

Sieve filtering SPAM and redirect
by Andre Luiz Paiz 12 Sep '16

12 Sep '16

Hi every body. I'm having difficulties to setup my filters correctly and I really need some help. This is my environment: Mail that is received on the system passes through a sieve_before script that checks the message header for SPAM tag and store it into the "Junk" folder. If no spam tag is found, mail goes to inbox. My horde webmail is integrated with sieve, so this allow users to create their own scripts to store mail in other folders or forward them to external accounts. And this are the problems I'm having: 1 - When users create a forward filter to redirect to external mail, mail that is stored inside the Junk folder are not forwarded; 2 - If I insert a "keep" parameter inside the sieve_before script to keep processing the rules, the mail is forwarded, but becomes duplicated and stored inside the inbox or other folders, if the user has more filters. 3 - If I move my sieve_before script to sieve_after, the same thing happened, one copy is stored on the user selected folder (inbox or filtered), including mail marked as SPAM. My needs are: I need to separate SPAM and HAM e-mail before users intervention (so I need sieve_before). But this SPAM e-mail has to be forwarded if a forward filter is created. Is it possible to use a sieve_after script that moves (instead of copy) the user mail marked as SPAM to the Junk folder even if it was stored in a different folder? Is that possible? Thanks a lot.

Use of obox2 and AWS S3
by Raymond Sellars 11 Sep '16

11 Sep '16

Hi Has anyone used or is using dovecot obox and S3 storage? I see very little chatter or documentation on it. Interested in how mature it is and technical items such as high availability and region replication. I'm guessing that multiple updates to a S3 mailbox is mitigated via the standard dovecot pattern of Director pointing multiple user sessions to a single/common dovecot node. And for disaster recovery - that's out of scope of dovecot and more reliant on S3 replication? Any one running a dovecot solution within AWS in general? Interested in best practice for the storage layer. Although NFS is possible its not really optimised for elastic cloud type hosting. Thanks Raymond

sieve - find in header
by Hajo Locke 09 Sep '16

09 Sep '16

Hello list, have a problem with sieve script. I want to perform an action if an arbitrary headerline contains a defined string. I tried with regex: if header :regex [".*"] ["searchstri.*"] { fileinto "junk"; } This is not working because regex is only used in 2nd argument ["searchstri.*"] In 1st argument [".*"] no regex is used, sieve expects just plain string. Something like this would work, if "x-myheader" contains "searchstring": if header :regex ["x-myheader"] ["searchstri.*"].... How to solve this case and find a string in arbitrary/unknown headerline? Thanks, Hajo

Sure, I understand this, but it's handy in lots of cases where you need to loading from an alternate location.

OK, the origin of your problem becomes clearer. You can hardcode these paths into the executables by doing something like env CFLAGS='-I/my'ssl/include' \ LDFLAGS='-L/your/ssl/lib -Wl,-rpath,/my/ssl/lib' \ configure ... I use this myself (except the -Wl part since these libs are symlinked to my shared library path). I think "-R/my/ssl/lib" might also be synonymous with -Wl,... > Dovecot is the only package I know of where there are like a thousand > places to put additional libs in the Makefile.am files, but most of > them are totally ignored by configure. I don't have that problem -- I use configure to tell dovecot where to find my self-compiled openssl, and the resulting executables load from where I want. Joseph Tam <jtam.home(a)gmail.com>

doveadm quota recalc returns a Segmentation fault
by Alessio Cecchi 07 Sep '16

07 Sep '16

Hi, with the latest dovecot-ee version (2.2.25.4 (5cb7c97)) if I run “doveadm quota recalc -u alessio(a)skye.xn--it-02t dovecot return a “Segmentation fault” (but the quota is update fine). Since dovecot version 2.2.24.3 (55cdc32) works fine. This is my quota backends configuration: plugin { quota = maildir:UserQuota quota2 = dict:Quota Usage::noenforcing:proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } I found that if I comment the line “quota2 = dict:…” doveadm quota recalc works fine. I have two quota backends because with dict I can store everybody's current quota usage in a SQL database for fast retrieving (like quota_clone plugin but I cannot switch to it immediately).

You can also affect where shared libraries are loaded using the LD_LIBRARY_PATH environment variable.

It's fine for a temporary working around problems (like this one, so you're absolutely right :-) However, no program should require that for regular use because you never know exactly if somebody in the chain of executed code removes certain environment variables. And also the opposite way, if Dovecot runs external programs, those might not play well with an existing LD_LIBARY_PATH and incompatible SSL libraries. For every program I compile myself, I link it against my custom OpenSSL library (always newest version; distributions usually tend to stick with a specific version and only apply security fixes). For most packages (eg, Exim, Apache HTTP, BIND, INN, OpenSSH, Mutt, wget etc.) it pretty straightforward. Even if not, usually I can find a quick solution myself. Dovecot is the only package I know of where there are like a thousand places to put additional libs in the Makefile.am files, but most of them are totally ignored by configure. And even if I modify the Makefile files after configure, again most of the additional options get ignored. Never seen it that complicated. As Dovecot is my favorite IMAP daemon, there's no way I'm giving up. :-) I'm totally confident that the developers will find a good solution. And I'm happy to test every patch they come up with. Greetings, Andreas

Cannot subscribe to Public mailbox
by MI 04 Sep '16

04 Sep '16

I'm trying to set up a Public mailbox, but when I try to subscribe to it in Thunderbird, nothing happens: it doesn't appear as a folder, and when I go back to the Subscribe window, it is unchecked again. I use postfix local dlivery, which created a Maildir when a mail arrived for this mailbox: /home/others/sharedmail/Maildir/{cur,new,tmp} (sharedmail is a system user so that Postfix can deliver the mail; it doesn't have a login shell or a password) To make sure it is not a simple filesystem permissions problem, I did "chmod -R a+rwX Maildir/" This is my current config ( I tried to keep it short by leaving only what might be relevant ): # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.9 ... mail_location = maildir:~/Maildir namespace { list = yes location = maildir:/home/others/sharedmail/Maildir prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox ... ... } prefix = separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } userdb { driver = passwd } Also, I'm not sure about the difference between type=public and type=shared. But anyway, I tried both with the same result.
