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. Yesterday night, I tried again, and everything worked :-) Regards!

Hi Steffen, but I have not set-up any namespace separator, so I understand that all namespaces use the default one, right? :-S Do you think I should better use the next command? dsync -u "user(a)domain.org" mirror maildir:/mnt/vmail/domain.org/user:LAYOUT=fs Felix On Tuesday 05 August 2014 12:07:16 Steffen Kaiser wrote: > On Tue, 5 Aug 2014, Felix Rubio Dalmau wrote: > > > But it replies this answer, that I do not understand: > > > > dsync(user(a)domain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) > > > > http://wiki2.dovecot.org/Namespaces > > "You should use the same hierarchy separator for all namespaces.

Migrating from maildir to mdbox
by Felix Rubio Dalmau 05 Aug '14

05 Aug '14

Hi all, I have (I think) migrated my dovecot mail format from maildir to mdbox. I have changed in 10-mail.conf the format from maildir to mdbox, and I have executed this command for all my users: dsync -u user(a)domain.org mirror maildir:/mnt/vmail/domain/user The only output of the command has been, for some users, this: dsync(user(a)domain.org): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota Is this important? How can I check that I am effectively using the new format? Thank you, Felix

Migrating from maildir to mdbox
by Felix Rubio Dalmau 05 Aug '14

Hi everybody, I have a virtual user setup that is using maildir, and I'd like to migrate it to mdbox. Following directions from http://wiki2.dovecot.org/Migration/MailFormat and keeping in mind that my maildir is in maildir:/mnt/vmail/%d/%u, after having updated 10-mail.conf I have tried to execute: dsync -u "user(a)domain.org" mirror maildir:/mnt/vmail/domain.org/user But it replies this answer, that I do not understand: dsync(user(a)domain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) What am I doing wrong? Thank you, Felix
