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

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

dovecot-lda 2.2.13 crashing when sieve_before used
by Christoph Lechleitner 05 Aug '14

05 Aug '14

Hi together! We use dovecot under Debian wheezy amd64, using the repository ... deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main Yesterday's routine upgrade to version 2:2.2.13-1~auto+130 (or some other upgrade that came along from Debian?) introduced a problem with mail delivery, which I was able to track down to a crash of dovecot-lda. Whenever I do something like ... /usr/lib/dovecot/dovecot-lda -d christoph.lechleitner(a)iteg.at <test.msg ... (with test.msg containing a raw e-mail message), dovecot-lda crashes. The gdb backtrace is: #0 buffer_free (_buf=_buf@entry=0x242eb20) at buffer.c:145 #1 0x00007f30d47ea4fd in array_free_i (array=0x242eb20) at /build/dovecot-8Ko2hw/dovecot-2.2.13/src/lib/array.h:108 #2 sieve_file_script_sequence_destroy (seq=0x242eb10) at sieve-file-script-sequence.c:242 #3 0x00007f30d47c963e in sieve_script_sequence_free (_seq=_seq@entry=0x7fffe2dbe900) at sieve-script.c:686 #4 0x00007f30d4a3d4b3 in lda_sieve_multiscript_get_scripts (svinst=svinst@entry=0x242abe0, label=label@entry=0x7f30d4a3e7c0 "sieve_before", location=location@entry=0x2416500 "/etc/dovecot/sieve/discard-viruses.sieve", scripts=scripts@entry=0x7fffe2dbe9b0, error_r=error_r@entry=0x7fffe2dbe998) at lda-sieve-plugin.c:271 #5 0x00007f30d4a3d7e5 in lda_sieve_find_scripts (srctx=0x7fffe2dbea40) at lda-sieve-plugin.c:740 #6 lda_sieve_deliver_mail (mdctx=<optimized out>, storage_r=0x7fffe2dbec00) at lda-sieve-plugin.c:973 #7 0x00007f30d5e05464 in mail_deliver (ctx=ctx@entry=0x7fffe2dbec70, storage_r=storage_r@entry=0x7fffe2dbec00) at mail-deliver.c:400 #8 0x0000000000402a92 in main (argc=3, argv=0x2402390) at main.c:437 The problem vanishes once I remove the sieve_before script, in our case /etc/dovecot/sieve/discard-viruses.sieve The sieve script does not contain anything fancy, and it works perfectly when used as sieve_default. It seems the mere presence of a sieve_before script triggers the problem. Some environment info: As of dovecot -n, I guess only the sieve related parts are relevant, if at all: plugin { sieve = /var/vmail/%d/%n/sieve sieve_before = /etc/dovecot/sieve/discard-viruses.sieve sieve_default = /etc/dovecot/sieve/default.sieve sieve_dir = /var/vmail/%d/%n/sieve-scripts } I also tried version 2:2.2.13-1~auto+138 from the dovecot-2.2.patched repository that I stumbled over while browsing the repository server. No difference regarding our problem. Our filesystem is ext4 disguised as simfs by the OpenVZ virtualization kernel. I'm pretty sure the filesystem does not matter with our problem. I'd be happy to re-test with testing releases, but I'd like to avoid setting up a full-blown test environment where unstable and bleeding edge versions would be ok.

Set an archive folder for every user
by Felix Rubio Dalmau 05 Aug '14

05 Aug '14

Hi everybody, I have a running postfix+dovecot installation, running flawlessly. The machine this setup is running onto has 2 mirrored SSD disks (in which dovecot stores the mails) and 2 mirrored regular HD. I'd like to keep the fresh emails in the SSD, and move them to an Archive folder after some days/weeks. Is there any way in dovecot to set up a folder for every user, that points to an external disk rather than the default one? Thank you, Felix

prefix behavior with Dovecot / Squirrelmail
by Will Yardley 05 Aug '14

05 Aug '14

Old: Dovecot 1.1.18 + Squirrelmail 1.4.8 + Imapproxy New: Dovecot 2.2.10 + Squirrelmail 1.4.22 (no Imapproxy) In both, we have: [dovecot config] namespace private { separator = . prefix = Mail. inbox = yes } (The 'Mail' prefix is set this way for compatibility reasons) $imap_server_type = 'dovecot'; $default_folder_prefix = 'Mail.'; $trash_folder = 'Mail.Trash'; $sent_folder = 'Mail.Sent'; $draft_folder = 'Mail.Drafts'; $show_contain_subfolders_option = true; $default_sub_of_inbox = false; (I know some of these are redundant with $imap_server_type, but that's how it's setup now). This works as we expect with the old setup - folders are set in, e.g., $maildir/.Sent, and we only see one set of each. With the newer one, it auto-creates folders as Mail.{Trash,Sent,Drafts}, which translates into Mail.Mail.{Trash,Sent,Drafts}. If I set $foo_folder to just 'Foo' (e.g., $trash_folder = 'Trash';), the auto-creation works as expected, however, now I have two sets of folders (one indented) in the folder list, and the set linking to Mail.{Trash,Sent,Drafts} (the indented ones), don't work. What's the easiest way to get the new setup working in a way that will cause the least change (preferably no change) to end-users. TIA w
