It's possible to talk to doveadm server as well via unix/tcp sockets. By default there is $base_dir/doveadm-server unix socket.

[Dovecot] lda sieve error using global after sieve script
by Tim Traver 19 Nov '10

19 Nov '10

Hi all, ok, so I've implemented an after sieve script with the following line in the plugins area : sieve_after = /home/mailboxes/sieve/to_spam_folder.sieve It seems to work ok on some accounts, but then I'm getting the following error in the deliver error log for many accounts : Error: sieve: script /home/mailboxes/sieve/to_spam_folder.sieve failed with unsuccessful implicit keep here is the script : require ["fileinto"]; # rule:[Spam and Virus Tag] if anyof (header :contains "Subject" "[VIRUS-TAG]", header :contains "Subject" "[SPAM-TAG]") { fileinto "Spam"; stop; } which is a very basic script that files stuff into the spam folder. I've checked some of the accounts, and the folder is there, and all appears to be ok... I'm not sure if its a compiling error or something, and I'm not sure if that error message means the message didn't even get delivered anywhere. it sounds like it gets discarded...does it? any help would be appreciated. here is my dovecot -n : [root@mda1 /local/logs]# dovecot -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 7.0-STABLE i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_fsync = always mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date imapflags notify mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_after = /home/mailboxes/sieve/to_spam_folder.sieve sieve_dir = ~/Maildir/sieve sieve_extensions = +notify +imapflags } protocols = none quota_full_tempfail = yes service auth { unix_listener auth-userdb { group = sn mode = 0600 user = sn } } ssl = no ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol lda { info_log_path = /local/logs/dovecot-deliver.log log_path = /local/logs/dovecot-deliver-errors.log mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } protocol sieve { managesieve_sieve_capability = comparator-i;ascii-numeric fileinto reject vacation imapflags notify include envelope body relational regex subaddress copy } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh }

[Dovecot] version_ignore=yes
by interfaSys sàrl 18 Nov '10

Hello, When upgrading Dovecot, I get this: Dovecot version mismatch: Master is v2.0.6, imap-login is v2.0.7 (if you don't care, set version_ignore=yes) This should not occur as version_ignore=yes is in dovecot.conf, at the top. Cheers, Olivier

[Dovecot] Question about mbox_snarf and dovecot2.0
by Jonathan Siegle 18 Nov '10

18 Nov '10

Hello, I'm running revision 10622:de9d6dae7fe5 on AIX 5.3 with some local mods for our inbox hash function. I'm having a problem doing a "select inbox" when I use the mbox_snarf plugin. When I run truss on the process I see the following stat calls: 614528: kread(9, " 1 s e l e c t i n b".., 4096) = 15 614528: statx("/gpfs/inbox/14/tstem38", 0x0FFFFFFFFFFFF2F8, 176, 0) = 0 614528: statx("/gpfs/users/t/s/tstem38/IMAP//gpfs/inbox/14/.imap/tstem38", 0x0FFFFFFFFFFFED98, 176, 0) Err#2 ENOENT 614528: statx("/gpfs/users/t/s/tstem38/IMAP//gpfs/inbox/14/tstem38", 0x0FFFFFFFFFFFEDD8, 176, 0) Err#2 ENOENT 614528: statx("/gpfs/users/t/s/tstem38/IMAP", 0x0FFFFFFFFFFFEC88, 176, 0) = 0 614528: statx("/gpfs/users/t/s/tstem38/IMAP//gpfs/inbox/14/tstem38", 0x0FFFFFFFFFFFEDD8, 176, 0) Err#2 ENOENT 614528: statx("/gpfs/users/t/s/tstem38/IMAP", 0x0FFFFFFFFFFFEC88, 176, 0) = 0 and the client gets: 1 NO [CANNOT] Invalid mailbox name For pathing I have: plugin.conf: mbox_snarf = /gpfs/inbox/%Ju/%u and mail.conf:mail_location = mbox:%h:INBOX=/var/spool/mail/%Ju/%u I verified that not using the mbox_snarf works just fine. I have no namespaces enabled. Thanks, Jonathan

[Dovecot] Dovecot and user's quota
by oriol llistes 18 Nov '10

18 Nov '10

Hi, We are planning to use Dovecot-2.0.5 (Maildir format) as IMAP server. Currently, we are using Postfix+UW-Imap (mbox format) with the following configuration: - Postfix: Sends new messages to /var/mail/user - UW-IMAP: Reads mails from /var/mail/user and moves them to ~/nsmail/mbox Using that configuration, when a user overtakes his HOME’s quota, the MTA is still able to send new messages to the user, although he cannot read it until he frees HOME space. Can we configure Dovecot to work in the same way? I mean… 1)Postfix must use /var/mail partition for new mails. 2)Dovecot must move these mails to user’s HOME. 3)User’s HOME must be in Maildir format. If that is not possible, how can we achieve an equivalent solution? Thanks in advance. Oriol.

[Dovecot] dovecot with Active Directory problem
by marie ot 18 Nov '10

18 Nov '10

Hello, I am using dovecot-2.0.6 with NetBSD amd64. Active Directory is used as an authentication server. (Windows Server 2008 R2) However, the message of "Operations error" was displayed first and it did not move. It solved it by understanding that this is because the authority of the user who used it for bind was insufficient, and adding to "Account Operators" group. # Though it is not the best. The error "Error: re_encode_request new request is" occurs, and it doesn't operate still as follows. Postfix operates though connects with LDAP. The following are samples. ------------------------ # Active Directory Server settings domain = example.com server_host = ldap://xxx.xxx.xxx.xxx:389 search_base = dc=example, dc=com version = 3 timeout = 30 # Active Directory Searcher settings bind = yes bind_dn = cn=Mail Administrator, cn=Users, dc=example, dc=com bind_pw = ********* # Filter Query query_filter = (&(&(objectCategory=person)(|(mail=%s)(userPrincipalName=%s)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = userPrincipalName result_filter = %s/ chase_referrals = no ------------------------ The packet was done with wireshark by using this definition and a capture doing and a similar test were done to dovecot. It is a setting of dovecot. ------------------------ hosts = xxx.xxx.xxx.xxx:389 dn = cn=Mail Administrator, cn=Users, dc=example, dc=com dnpass = ********* auth_bind = no ldap_version = 3 base = dc=example, dc=com user_attrs = unixHomeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPrincipalName=user,unixUserPassword=password pass_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) iterate_attrs = userPrincipalName=user iterate_filter = (&(objectCategory=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) default_pass_scheme = MD5 ------------------------ # Schema of LDAP is matched to Windows Services for UNIX, # and the password is made a hush with MD5. Both dovecot and postfix the first "bindRequest" was quite the same demand and the results. Next, dovecot demanded query of "userPrincipalName" and "unixUserPassword". It seems to be ok for the result. # This fails if it doesn't add to "Account Operators" group. However, "name" and "simple" were issued by the blank (anonymously?) as for the following next demand (bindRequest). In addition, query of "userPrincipalName" and "unixUserPassword" is issued to "cn=Configuration, dc=example, dc=com" afterwards. And, "Operations Error" is returned because of this. Error description in LDAP packet: ------------------------ errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0 ------------------------ Because LDAP is unprofessional, it has not understood though the source code was seen. Do you serve as a reference? Thanks powerful codes.
