Hello Everyone, I saw the text about the change and needing to define an inbox namespace. Everything seems to work fine except doveadm. I get the following from a cronjob that has worked well for years now. doveadm(account(a)example.com): Error: Syncing mailbox TRASH failed: Mailbox doesn't exist: TRASH doveadm(account(a)example.com): Error: Syncing mailbox TRASH failed: Mailbox doesn't exist: TRASH doveadm(account(a)example.com): Error: Syncing mailbox TRASH failed: Mailbox doesn't exist: TRASH The cronjob is: 1 4 * * * doveadm expunge -A mailbox TRASH SAVEDBEFORE 30D What is the problem?

[Dovecot] auth-worker problem here.
by Marko Weber 07 Jun '12

07 Jun '12

hello, in howto for gentoo i found this: To tell Postfix about the maps that you've just set up, add the following (substituting mysql for pgsql if you're on PostgreSQL) to the bottom of /etc/postfix/main.cf: virtual_alias_maps = mysql:/etc/postfix/sql_virtual_alias_maps.cf virtual_mailbox_domains = mysql:/etc/postfix/sql_virtual_domain_maps.cf virtual_mailbox_maps = mysql:/etc/postfix/sql_virtual_mailbox_maps.cf Tip: Because this is using the Dovecot's LDA, all results from virtual_mailbox_maps are ignored beyond checking if they exist. I added in the mysql db an alias postmaster(a)domainn.tld that should be forwarded to name(a)domainn.tld. The tip above tells me when using dovecot lda the virtual_alias_maps is ignored by dovecot. now when i send a mail to postmaster(a)domainn.tld the mail is not transported to name(a)domainn.tld. in logfile i see this: dovecot: auth-worker: sql(postmaster(a)zbfmail.de): Unknown user how can i tell dovecot to also use the virtual_alias_maps? thank you marko

[Dovecot] Problem with Dovecot and AD LDAP auth
by Алексей Переклад 07 Jun '12

07 Jun '12

Hi. Seems it's a bug in dovecot auth. I have FreeBSD 8.1-RELEASE-p1 and I tried 1.2.17 and 2.1.7 versions of Dovecot, and still no luck. The problem: when I set in dovecot-ldap.conf: base = CN=Users,DC=domain,DC=local everything works fine. But if I set: base = DC=domain,DC=local mail client can't authorize. /var/log/dovecot.log says: =============================================== Jun 07 18:07:17 auth: Debug: auth client connected (pid=14611) Jun 07 18:08:11 auth: Debug: client in: AUTH 1 PLAIN service=imap session=G1//aeLB6wAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55787 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): result: uid missing Jun 07 18:10:18 imap-login: Info: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 127 secs): user=<>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<G1//aeLB6wAKAABu> Jun 07 18:10:18 auth: Debug: client in: CANCEL 1 Jun 07 18:10:18 auth: Debug: auth client connected (pid=14706) Jun 07 18:10:26 auth: Debug: client in: AUTH 1 PLAIN service=imap session=n6IBcuLB7AAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55788 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): Connection appears to be hanging, reconnecting Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): result: uid missing Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): Request lost Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): ldap_search(base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway))) failed: Operations error Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:13:18 imap-login: Info: Disconnected: Inactivity (auth failed, 1 attempts in 172 secs): user=<gateway>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<n6IBcuLB7AAKAABu> ============================================ My dovecot-ldap.conf: =============================== ldap_version = 3 hosts = ad.domain.local base = DC=hrom,DC=local scope = subtree dn = CN=mailserver,CN=Users,DC=domain,DC=local dnpass = here_is_pass auth_bind = yes pass_attrs = uid=user pass_filter = "(&(objectClass=person)(sAMAccountName=%u))" user_attrs = name=mail=maildir:/var/mail/virtual/hrom.local/%n user_filter = "(&(objectClass=person)(sAMAccountName=%u))" =================================================== I need base = DC=domain,DC=local for searching for user's accounts in different OU of my AD. If I set base = CN=Users,DC=domain,DC=local, Dovecot can't authorize user accounts from OU. P.S.: Postfix with base = DC=domain,DC=local works perfectly, so the problem is not with our domain controller (LDAP server as well) .

[Dovecot] Email auto purging applied to all mail folders
by Joe V Aldeguer 07 Jun '12

07 Jun '12

Hello, Is it possible to have this done not only for spam and trash folder but lets say like the user inbox and any user created mail folders too? My ultimate goal is to have a way to automate the email deletion process of emails stored in the user inbox or mail folders when it reaches a specified date. My boss wants to force users to keep emails only a month old anything beyond that will be deleted. Has anyone done this using dovecot and are there any guides available? I am also open to suggestions for commercial solutions but so far searching online for solutions only comes up with email archiving. The dovecot version I have installed is version 2.0.19. Thanks in advance. - Joe

[Dovecot] dsync backup doubles quota
by Patrick Westenberg 07 Jun '12

07 Jun '12

Hi everyone, I recognized a very strange behavior when doing backups of my mdbox mailboxes. After the backup the quota for each mailbox is twice as much as before the backup and I have to recalculate the quota to get the former/correct information. root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - root@mb01:~# doveadm backup -u test(a)example.com mdbox:/home/example.com/test root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 10 10240 User quota MESSAGE 22 - root@mb01:~# doveadm quota get -u test(a)example.com root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - Is this a bug or normal behavior? Regards Patrick

[Dovecot] best practises for mail systems
by Костырев Александр Алексеевич 06 Jun '12

06 Jun '12

hello! Can someone point me to some best practices in building high-available scalable mail system or! share your own success stories. I've read article in LJ "Building a Scalable High-Availability E-Mail System with Active Directory and More" but it seemed to be outdated and there's a single point of failure (Master node). What I want to achieve: high-available, horizontaly scalable, with no single point of failure mail solution. Available hardware: intel mfsys25 modular server with 2 storage controllers, 2 switches, 4 power supply blocks with - 2 blade-servers in mfsys with: 2xIntel Xeon E5620 @ 2.40GHz with 8 cores each - promise vtrak e610s (2 storage controllers, 2 power supply blocks) - 6x 2TB SATA Hitachi HDS72302 We decided to go for KVM virtualization and glusterfs for live migration for vm image but that's not what this is all about :) We installed centos on host systems. for now while we could think of two ways to go: The first way (currently at testing stage): On each host system we created one VM and passed through 3x2TB disks into it. In guests vms on top of this disks we made XFS and fired up glusterfs with distributed replicated volumes for our mailstorage. so it looks like this: vm1 replicate vm2 disk1 ------------> disk4 disk2 ------------> disk5 disk3 ------------> disk6 in each vm we mounted glusterfs and pointed dovecot to that dir for mail creation (as ltmp) and imap4 user access. also we use exim as smtp. So, with glusterfs as mailstorage we can go for LVS to load balancing for exim and dovecot. so wherenever one of host systems (hence one of mail vms) goes down, users don't notice that 'cause LVS points them to working smtp and imap4 servers and they get their mail 'cause of glusterfs. Pros: - high-available - horizontaly scalable - with no single point of failure Cons: - not quite sure if glusterfs is production ready solution 'cause I've experienced split-brains during setting it up - IO performance issue. Though we didn't yet run any io tests, but glusterfs uses fuse to mount on clients. And guys on #gluster told me writing to the glusterfs mount will not be strictly local io. The second way: split up the users mail with: two back-end VMs each other on DIFFERENT host system with - fat mailstorage with raid1+linear mode (mdadm)+XFS - dovecot/exim-back-ends and two VMs for nginx-based proxy servers for imap4 and smtp - nginx can redirect user to right back-end through HTTP-php-based logic. Pros: - we split up not only load for exim/dovecot but users mail IOs too - no split-brains Cons: - If one of the host systems (hence one of back-end VMs with storage) goes down, half of our users is unhappy P.S. Sorry if this place is way wrong to ask for such things.

[Dovecot] No ports listening

Please forgive my newbie post but this has me stumped. I've been a happy Dovecot 0.X and 1.X admin for years but something in my first 2.X configuration is oddly broken.
