Dovecot and remote SASL Client via TLS
by Gerhard Wiesinger 08 Aug '14

08 Aug '14

Hello, Is it possible to configure Dovecot as SASL client for central authentication (also remotely via TCP/TLS)? Following use case: IMAP server (host 1) <=> Windows Domain Controller and /etc/shadow authenticator via pam (host2) Should work as: IMAP server (host 1) <=> SASL Client via TLS <=> Network <=> SASL Server via TLS <=> Local SASL via pam <=> Windows Domain Controller and /etc/shadow authenticator via pam (host2) Thank you. Ciao, Gerhard -- http://www.wiesinger.com/

invalid/unknown path to storage
by Benjamin Connelly 08 Aug '14

08 Aug '14

Am I correct: pigeonhole now wants the symlink to the filter file to use an absolute path instead of the relative paths we had? i.e.) sieve-filterfile@ -> /home/mail/domain/user(a)domain/roundcube.sieve instead of sieve-filterfile@ -> roundcube.sieve Dovecot logs these: dovecot: managesieve(user(a)domain.org): Warning: sieve-storage: Active sieve script symlink /home/mail/domain.org/user(a)domain.org/sieve-filterfile is broken: invalid/unknown path to storage (points to roundcube.sieve). and the debug log: Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: Pigeonhole version 0.4.3 initializing Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts. Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using active sieve script path: /home/mail/domain.org/user(a)domain.org/sieve-filterfile Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using sieve script storage directory: /home/mail/domain.org/user(a)domain.org/ Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using permissions from /home/mail/domain.org/user(a)domain.org/: mode=0700 gid=-1 Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: relative path to sieve storage in active link: I found if I manually delete a symlink and replace it using the full path: sieve-filterfile -> /home/mail/domain.org/user(a)domain.org/roundcube.sieve then everybody is happy. So I'm looking to make a configuration change (and then change all existing symlinks.) I just wanted to check with the list about the two settings we return as part of the user_query: concat(homedir, maildir, 'sieve-filterfile') as sieve, concat(homedir,maildir) as sieve_dir In testing it seems like changing 'sieve' to return not the whole path but just the link name, actuall causes pigeonhole to properly make the symlink with full path! Does this seem right? FreeBSD (8.4) dovecot-pigeonhole (0.4.3_1) dovecot2 (2.2.13_3) Benjamin

Pigeonhole version 0.4.3 on FreeBSD-10
by Jerry 07 Aug '14

07 Aug '14

Thu, 7 Aug 2014 06:22:01 -0400 I am running Pigeonhole version 0.4.3 on a FreeBSD 10 machine. How do I actually trace which rule in my sieve file is causing a specific action on a specific email. Other then eliminating each rule one by one and rerunning the script to isolate it, how can I discover what rule is causing the problem? Thanks! -- Jerry

Is atomic MOVING of messages between IMAP folders possible?
by Greg Sullivan 07 Aug '14

07 Aug '14

I would like to use a shared IMAP account, with multiple users accessing it simultaneously. The users would take ownership of messages by first attempting to MOVE the messages from the Inbox, into their private IMAP folder, still within the same account. Now, since there will be multiple users competing for the same messages, I naturally want only ONE of the simultaneous moves to be successful at a time. So far, this isn't working. If I do the move from two clients, simultaneously, the messages can go to *both *destination folders - duplicates can result. Is it possible to configure Dovecot and/or an IMAP client to behave the way I want it to? If the answer to this is YES, then I'll offer my config details. If the answer is NO, the next question is - do any email systems at all behave the way I want? (I tried a hosted Exchange/OWA service - it has the same problem) Thanks & regards, Greg.

Panic on alway_bcc mail with attachment while using sdbox
by Fischer, Bernhard 07 Aug '14

07 Aug '14

I do always get a panic on service lmtp, while receiving a mail by postfix through always_bcc, containing an attachment. If the bcc recipient would be supplied by a small delay, I would say that the panic wouldn't occur, but I don't know how to verify this. dovecot is configured with 'mail_attachment_dir' and the public namespace location is sdbox dovecot log: Aug 6 14:18:02 dovecot dovecot: lmtp(20367, vscanner(a)fischer-ing.de) Panic: file fs-api.c: line 615 (fs_copy): assertion failed: (src->fs == dest->fs) Aug 6 14:18:02 dovecot dovecot: lmtp(20367, vscanner(a)fischer-ing.de) Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x66676) [0x443676] -> /usr/lib/dovecot/libdovecot.so.0(+0x66700) [0x443700] -> /usr/lib/dovecot/libdovecot.so.0(+0x18c23) [0x3f5c23] -> /usr/lib/dovecot/libdovecot.so.0(+0x2278b) [0x3ff78b] -> /usr/lib/dovecot/libdovecot-storage.so.0(sdbox_copy+0x4ad) [0x23c6ad] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x62) [0x27da72] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_save_using_mail+0x2b) [0x27db4b] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver_save+0x1a1) [0x5dd3c1] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver+0x143) [0x5dd7c3] -> dovecot/lmtp() [0x804d090] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x43) [0x455973] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0x456c4b] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x48) [0x4558b8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x2e) [0x3fb0ee] -> dovecot/lmtp(main+0x1b3) [0x804b463] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x5f9d26] -> dovecot/lmtp() [0x804b1e1] Aug 6 14:18:02 dovecot dovecot: lmtp(20367, vscanner(a)fischer-ing.de) Fatal: master: service(lmtp): child 20367 killed with signal 6 (core dumps disabled)

Multiple userdb on specific ports
by Zachary Sturgeon 06 Aug '14

06 Aug '14

Hello everyone, Is it possible to, from one instance, bind a single userdb to a specific listen port in Dovecot? For example, requiring passwd or PAM authentication on IMAP port 143, but using an SQL passdb only on port 8143?

Important emails
by André Rodier 06 Aug '14

06 Aug '14

Hi, Sorry if I am not posting on the right mailing list, but I need email and especially IMAP experts opinion. I have developed a small perl script for Amavis that tries to recognise business emails from bulk & mailing lists, in order to promote 'important' emails, ala google. This is a feature I found very useful in corporate environments, where a lot of users are receiving advertisements, but not consider it as spam. (For info, the code is here: https://github.com/arodier/emclass) My script add an email header (X-Email-Type), and dovecot uses a virtual folder called 'Important' to present them. I know there is IMAP labels, and they are server side stored. I have successfully played with Thunderbird, but IMHO, it's not very reliable. The name of the label is the responsibility of the email client. As a result, if one client decided that $Label1 is 'Important', and $Label2 is 'Business', other clients should be configured exactly the same. I wonder if there is some norm - or convention - to attach labels to email headers, or if such a header exists, for instance a header called e.g. 'X-Tags', 'X-Keywords' or 'X-Labels'. So, once stored, an email could contains - for instance - a header like this: X-Tags: Travel,Advertisement,France. Then, it would be easy to have server side search for labels. Thanks for your feedback. Kind regards, André.

maildir: could lda/lmtp log filenames?
by A. Schulze 06 Aug '14

06 Aug '14

hello, on a mailstorage server receiving messages per lda/lmtp I like to pimp my logfile. when starting to search for a specific message I have a queueid. I like to combine that id with the filename the message has after delivery to a maildir. I know, that will not work with other formats then maildir. Aug 6 11:37:30 mailserver postfix/lmtp[17884]: 3hSnmj208Zz259d: to=<rcpt(a)example.org> relay=$lmtp-server status=sent (250 2.0.0 $dovecot-id) Aug 6 11:37:29 $lmtp-server dovecot: lmtp(1440, rcpt(a)example.org) $dovecot-id: sieve: msgid=<..>: stored mail into mailbox 'INBOX/folder' and exactly there I would like to see "stored mail into mailbox 'INBOX/folder/new/FILENAME'" yes, I know, I /should/ user doveadm and avoid access messages via filesystem but in that case it would be much faster to access the information I need. Any ideas? Andreas

Hi Steffan, Solved! Thank you very much for you help. I think there was a configuration error and when I used the "separator" keyword was not working properly.
