Just to be sure that I didn't misunderstand your proposed configuration: @mx1: plugin { mail_replica = remote:vmail@mx2.example.tld } @mx2: plugin { mail_replica = remote:vmail@mx1.example.tld } I do need to define one mail_replica plugin at each server pointing to the other one, correct?

[Dovecot] duplicates with multiple To/CC and sieve redirect copy
by Adam Szpakowski 08 Mar '12

08 Mar '12

Hi, In one installation we are using sieve "redirect :copy" to create copy of the incoming email (local boss gets copy of its employees mails). There is a problem when the incoming email has multiple To/CC entries with local users. Multiple copy/redirects are created (one for each employee) and there are multiple copies in "boss" account. Each of this emails has the same Message-ID. Is there a way to detect those duplicates and discard them when saving copies into boss account? There was a discussion on the list a while ago (Feb 10/11, 2011) mentioning this problem, but with no clear solution. We are using Dovecot 2.0.15. Mail is delivered via LMTP (MDA/postfix is on separate machine then MAA/dovecot). -- Adam Szpakowski

[Dovecot] Failing: doveadm sync <--remote host--> dsync mirror
by Michael Grimm 08 Mar '12

08 Mar '12

Hi -- I'm used to dsync my two mailservers running 2.0.16. Today, I did upgrade one server to 2.1, and doveadm sync is throwing to following error: mail> doveadm sync -f -u test ssh vmail(a)remote-host.tld dsync -v -f -u test doveadm(test): Fatal: All your namespaces have a location setting. It should be empty (default mail_location) in the namespace to be converted. Same error with old running command: vmail> dsync -v -f -u test mirror ssh vmail(a)remote-host.tld dsync -v -f -u test doveadm(test): Fatal: All your namespaces have a location setting. It should be empty (default mail_location) in the namespace to be converted. Here's an excerpt of my doveconf -n: mail> doveconf -n mail_home = /var/mail/homedirs/%n mail_location = mdbox:/var/mail/maildirs/%n passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } Reverted back for the time being (production servers) until I do understand the issue. Searching Google with "Fatal: All your namespaces have a location setting." only shows closed bugs back in 2010. Do I have to upgrade both servers to get syncing running? Any hint, help is highly appreciated. Thanks, Michael

[Dovecot] FW: Centos 6 + dovecot 2 + mail.app + imap

Anybody also experiencing that imap processes are kept running/open by mac osx mail.app, so eventually users are getting to the mail_max_userip_connections limit? Outlook / other clients seem to run fine. Thanks, Marc

[Dovecot] Log sync errors (again)
by Stephen Davies 06 Mar '12

06 Mar '12

As suggested earlier, I deleted all .imap directories and the log sync errors stopped - for a while. They have now returned. It seems to happen for every mailbox that gets accessed. Dovecot version 2.1.1 with pidgeonhole 3.0.0 on Mandriva Linux. Could this interfere with sieve filters? Several users have filters but none of them seem to do anything. Mar 7 09:25:51 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=38708 for /home/john/Mail/INBOX/.imap/Weather Summaries/dovecot.index: Extension header update points outside header size Mar 7 09:25:51 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=41576 for /home/john/Mail/INBOX/.imap/Zerna/dovecot.index: Extension header update points outside header size Cheers and thanks, Stephen -- ============================================================================= Stephen Davies Consulting P/L Voice: 08-8177 1595 Adelaide, South Australia.

[Dovecot] Master Users
by Kelsey Cummings 06 Mar '12

06 Mar '12

I have a setup where I need to use a Master User account to login on behalf of users normally authed via PAM. Is there any existing mechanism that will allow master users to be wired down to specific ip address rather than having these very magic user/pass combos be valid from any random host? It would be totally acceptable to be able to say that master logins were only valid from a specific list of hosts rather than wiring specific master users to specific hosts. -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc.

[Dovecot] LDAP auth_bind fails
by Pol Bettinger 06 Mar '12

06 Mar '12

Hello, I wanted to configure dovecot for using auth_bind but didn't succeed to me it seems like it does always an anonymous bind. Dovecot version 2.1.1 (I started with 2.1.0 and hoped 2.1.1 would fix it) I tried to play around with the base, pass_attrs,pass_filter to no avail but didn't succeed. Looking at a wireshark trace i only saw 7 packets and it seemed to me dovecot did only an anonymous bind. any help would appreciated Sincerely Pol Bettinger output of mail.log: Mar 6 12:16:34 Dell dovecot: auth: Debug: client in: AUTH#0112#011CRAM-MD5#011service=imap#011secured#011lip=192.168.16.27#011rip=192.168.16.20#011lport=993#011rport=51838 Mar 6 12:16:34 Dell dovecot: auth: Debug: client out: CONT#0112#011PDQ1NjgyMjE3NjYyMDk3NjkuMTMzMTAzMjU5NEBEZWxsPg== Mar 6 12:16:34 Dell dovecot: auth: Debug: client in: CONT<hidden> Mar 6 12:16:34 Dell dovecot: auth: Debug: password(arvi(a)arvoreen.net,192.168.16.20): passdb doesn't support credential lookups Mar 6 12:16:36 Dell dovecot: auth: Debug: client out: FAIL#0112#011user=arvi(a)arvoreen.net output of dovecot -n: # 2.1.1: /etc/dovecot/dovecot.conf # OS: Linux 3.0.0-15-generic i686 Ubuntu 11.10 ext4 auth_debug = yes auth_default_realm = arvoreen.net auth_mechanisms = plain digest-md5 cram-md5 auth_verbose = yes base_dir = /var/run/dovecot/ mail_location = maildir:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n 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 ihave namespace inbox { inbox = yes location = mailbox Archive { auto = create special_use = \Archive } mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { auto = create special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = create special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-ldap_pass.conf.ext driver = ldap } plugin { sieve = /var/sieve/%d/%1n/%n sieve_dir = /var/sieve/%d/%1n/%n } protocols = imap lmtp sieve service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/certs/webmail.arvoreen.pem ssl_key = </etc/ssl/private/webmail.arvoreen.key userdb { args = /etc/dovecot/dovecot-ldap_user.conf.ext driver = ldap } protocol lmtp { mail_plugins = " sieve" } output of cat /etc/dovecot/dovecot-ldap_pass.conf.ext: hosts = 127.0.0.1:389 auth_bind = yes auth_bind_userdn = uid=%n,ou=Users,dc=arvoreen,dc=net base = ou=Users,dc=arvoreen, dc=net ldap_version = 3 olcAccess infomation: olcSuffix: dc=arvoreen,dc=net olcAccess: {0}to attrs=userPassword,shadowLastChange by self write by anonymou s auth by dn="cn=admin,dc=arvoreen,dc=net" write by * none olcAccess: {1}to dn.base="" by * read olcAccess: {2}to * by self write by dn="cn=admin,dc=arvoreen,dc=net" write by * read
