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

Solr indexing appends domain to users
by G H 04 Aug '14

04 Aug '14

My users are set up as "admin", "john", etc -- as opposed to john(a)example.com. When I run test command "/usr/libexec/dovecot/dovecot-lda -d admin < /tmp/mymail.txt", the mail is successfully imported with Solr, Tika (yay). However, results are never found when I search within IMAP. Why? Dovecot is appending the domain name to the user and admin fields of the Solr record ("admin(a)example.com" instead of just "admin") during index. But during searching, Dovecot is only searching for the user directly, from the Solr logs: q=body:"TESTCONTENT"&fq=%2Bbox:7dff0b0d4f84df53f25300003d823887+%2Buser:"admin" If I rerun the query via the Solr web gui with user:"admin(a)example.com", the message is found. How do I disable appending the domain name to the solr index names? Thanks, G H

I'm getting 2 errors which are probably related, the second of which I haven't actually seen an issue with yet (I just found it looking at the error log) The issue is that I cannot change my subscriptions through Thunderbird (version 31.0). I created the subscriptions through Thunderbird, but now it won't let me change them. dovecot responds with sutff like this when I sniff network traffic or configure Thunderbird to log IMAP traffic: 10 NO [NOPERM] No permission to modify subscriptions The time stamp on the .subscriptions.lock file gets updated every time I try to make a change. To test I edited .subscriptions by hand and forced Thunderbird to try to subscribe something and I got access to the folder I added, so I presume it is reading the file correctly. Permissions on~jreid/mail is 0700, the existing .subscriptions file is 0640 and .subscriptions.lock file is 0600. all the files are owned by me and their group is my primary group (not mail). As for the second error, the dovecot.index.log.newlock file gets created but no dovecot.index.log file gets created. And dovecot would have created the directory tree to those files itself... I'm new to dovecot but not Unix or IMAP so I'm sure this is just some configuration option I've missed, any help would be most appreciated. $ /opt/csw/bin/doveconf -n # 2.2.12: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc disable_plaintext_auth = no first_valid_uid = 100 mail_access_groups = mail mail_location = mbox:~/mail:INBOX=/var/share/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap ssl_cert = </etc/opt/csw/ssl/certs/dovecot.pem ssl_key = </etc/opt/csw/ssl/private/dovecot.pem userdb { driver = passwd } $ doveadm log errors [...] Aug 03 16:47:02 imap(jreid): Error: rename(/home/jreid/mail/.subscriptions.lock, /home/jreid/mail/.subscriptions) failed: Permission denied Aug 03 16:52:49 imap(jreid): Error: rename(/home/jreid/mail/2012/.imap/Received/dovecot.index.log.newlock, /home/jreid/mail/2012/.imap/Received/dovecot.index.log) failed: Permission denied -- joe
