[Dovecot] questions about SPECIAL-USE and virtual
by l.chelchowski＠eurocar.pl 23 Apr '12

23 Apr '12

Hi, I have some questions about Special-Use and virtual namespace: I want to create a virtual namespace with mailboxes: Sent, Unread, Flagged, All. 1. Is it enough to put in the config file: mailbox virtual/Sent { auto = subscribe special_use = \Sent } mailbox virtual/Unread { auto = subscribe special_use = \Unread #Is it correct? } mailbox virtual/Flagged { auto = subscribe special_use = \Flagged } mailbox virtual/All { auto = subscribe special_use = \All } and it would displays mail from every namespace I have subscribed (Shared, Public)? OR I have to make also dovecot-virtual files? 2. In dovecot-virtual file can I put for mailbox virtual/Sent something like: * \Sent 3. Is the http://wiki2.dovecot.org/Plugins/Virtual full documented, if not , where can I find it? 4. Is there a documentation for Special-Use? -- Łukasz

[Dovecot] Bug in HIGHESTMODSEQ when MODSEQ tracking is not enabled for version 2.0.18.
by Glenn Wurster 23 Apr '12

23 Apr '12

Greetings, I'm new to the list. I have encountered what I believe to be a bug in the return of HIGHESTMODSEQ when talking to a IMAP client. HIGHESTMODSEQ does not appear to be incrementing when a new message arrives. The exact steps I took are: 1) Create a new mail account 2) Send a mail to the account, check that you can receive the email. Send a second mail to the account. 3) perform a SELECT on the mailbox from a new session. PMLK4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest PMLK4 OK [READ-WRITE] Select completed. 4) Retrieve the mail. Then perform another SELECT on the mailbox from yet another session. LLEP4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest LLEP4 OK [READ-WRITE] Select completed. 5) Send another mail to the account, and check SELECT again. FKDA4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 3 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 4] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest FKDA4 OK [READ-WRITE] Select completed. It appears as if HIGHESTMODSEQ is not being updated. I can get HIGHESTMODSEQ to start updating correctly if I send a "UID FETCH 1 MODSEQ" or similar command, which appears to enable MODSEQ tracking at the server (according to the comment around line 173 in file src/lib-index/mail-index-modseq.c), but until that command is sent, MODSEQ tracking is not enabled and hence HIGHESTMODSEQ is always going to return 1. According to RFC4551, the combination of HIGHESTMODSEQ and UIDVALIDITY should be sufficient to determine if the metadata associated with the mailbox has changed, but in this case looking at only those two parameters does not yield sufficient information about changes in the mailbox. The mail client I'm using relies on the combination of HIGHESTMODSEQ and UIDVALIDITY to determine if there are changes in the mailbox, and hence does not see new mail come in. It seems that Dovecot should not be returning HIGHESTMODSEQ in response to a command if MODSEQ tracking is not enabled, but I could be wrong. I've attached my configuration (it's Dovecot 2.0.18 running on Debian Stable). Let me know if you need more information.

by Frank Bonnet 23 Apr '12

23 Apr '12

Hello Maybe it's a coincidence but it "seems" since I upgrade from 2.0.18 to 2.1.3 that some French characters ( a with accents by example ) are not well displayed anymore using thunderbird and are replaced by a "?" character Thanks for any info

[Dovecot] imapc / namespace question
by René Neumann 23 Apr '12

23 Apr '12

Hi, I've got two questions regarding imapc and namespaces: 1) Is there a way of stating, that I only want part of the hierarchy on the end of an imapc connection to be available here? My "problem": On the other end the layout is: INBOX.Shared.{some,nice,folders} If I mirror this into my dovecot hierarchy with prefix "Gemeinsam" I get the following folder structure: Gemeinsam.INBOX.Shared.{some,nice,folders} But I want to ignore the two top-most parts of the hierarchy, i.e. I want it to look: Gemeinsam.{some,nice,folders} Is this possible? I tried with 'location=imapc:INBOX.Shared.' but this did not change anything. 2) "Private" namespaces only make sense, if location contains something user-specific like "%u" or "~". Is this correct? If yes: Is there some other way to make something like an imapc connection only appear for one user, if there is nothing in the location or imapc_user to denote the user it belongs to and hence I cannot use "private"? The only way I see currently is to use "shared" and set up ACLs to forbid all users except one to access the namespace (which gets slightly ugly as I have to use global ACLs, as -- I think -- there is no way to store ACLs for an imapc storage). Thanks, René

This is just one dovecot IMAP client process moaning after another user client process pulled the rug out from under it by modifying the mailbox. I get a few dozen log entries of this sort per week with ~200 IMAP users without shared access. Unless your users actually complain about a problem, I think it's safe to ignore them.

Hello, after running dovecot for a while, I stumbled accross the warning, not to have mail and home directory settings point to one and same directory. Here is the output of dovecot -n: > dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.4 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_max_userip_connections: 100 mail_privileged_group: mail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_full_filesystem_access: yes mbox_write_locks: fcntl dotlock namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: xxxx(a)xxxx.org mail_plugins: sieve log_path: auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail In "args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes" I should delete "Maildir". My question is: What files do I have to copy from /Maildir to the home directory /var/vmail/%d/%n/ ? Are there other side effects, I have to consider? Thank you very much for your help! Stefan

[Dovecot] sieve against ldap in Dovecot 1.2 vacation messeage
by Victor Oñate 22 Apr '12

22 Apr '12

Hi. I need configure "sieve" against ldap this is my file configuration dovecot.conf plugin { quota = dirsize:user sieve_dir = ~/sieve } protocol lda { mail_plugins = sieve } auth default { mechanisms = plain passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = nobody } I dont know what I have to put in dovecot-ldap.conf, ofcourse I have a atribut in LDAP by user with a vacation messeage "I'm out of office, please contact Mr. Black" this is dovecot-ldap.conf hosts = server auth_bind = yes ldap_version = 3 base = dc=dominio,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) The principal idea is keep the control the message by user with LDAP and Dovecot(IMAP). without touching the postfix configuration file is that possible, or am I dreaming. Thanks.. Victor Oñate.
