[Dovecot] dsync verbosity, summary of transfer
by Alan McGinlay - SICS 10 Dec '13

10 Dec '13

Hi! I am playing with dsync and trying to fix an issue I have mentioned in another thread (subject: "Re: [Dovecot] Dsync error: Couldn't drop privileges: getgrnam") and feel that dsync could use some additional informational output. It would be particularly helpful while experimenting with a migration if it could output a transfer summary and / or log separately. A summary could be similar to that which imapsync outputs after completion, for example: ++++ Statistics Transfer started on : Thu Dec 5 20:30:05 2013 Transfer ended on : Thu Dec 5 20:32:00 2013 Transfer time : 114.3 sec Messages transferred : 7 Messages skipped : 766 Messages found duplicate on host1 : 0 Messages found duplicate on host2 : 0 Messages void (noheader) on host1 : 0 Messages void (noheader) on host2 : 0 Messages deleted on host1 : 0 Messages deleted on host2 : 9 Total bytes transferred : 71820 (70.137 KiB) Total bytes duplicate host1 : 0 (0.000 KiB) Total bytes duplicate host2 : 0 (0.000 KiB) Total bytes skipped : 10070561 (9.604 MiB) Total bytes error : 0 (0.000 KiB) Message rate : 0.1 messages/s Average bandwidth rate : 0.6 KiB/s Reconnections to host1 : 0 Reconnections to host2 : 0 Memory consumption : 90.5 MiB Biggest message : 39274 bytes Detected 0 errors

[Dovecot] Dovecot+LDAP lda problem
by Zeljko Culek 10 Dec '13

10 Dec '13

Hello everyone, I need some help with Dovecot+LDAP config and local delivery. We're using Dovecot 2.0.9 on Centos 6.4. Before, we used Qmail with the same LDAP. Our LDAP accounts have the attribute deliveryMode which we used for mailing lists (OK, they are in fact mailing groups rather than lists). When the attribute is set to deliveryMode = nolocal Qmail did not deliver mail to the list mailbox, only to the accounts on the list/group. Now with Dovecot(+postfix) I can't achieve the same behaviour. Can Dovecot be set up not to deliver the mail to the list mailbox if the list has the attribute deliveryMode = nolocal? This is my /etc/dovecot/conf.d/dovecot-ldap.conf.ext hosts = xxx.xxx.xxx.xxx auth_bind = yes dn = cn=admin,dc=nth,dc=ch dnpass = xxxxxxxxxx ldap_version = 3 base = dc=nth,dc=ch #deref = always scope = subtree user_attrs = mail=user user_filter = (|(&(objectclass=inetOrgPerson)(mail=%u))(|(mailAlternateAddress=%u))) pass_attrs = uid=user pass_filter = (&(objectclass=inetOrgPerson)(|(mail=%u)(mailAlternateAddress=%u))) default_pass_scheme = CRYPT Basicaly, I want to make check: if deliveryMode=nolocal > do not deliver to mail=some.mail(a)tld.com (only to mailForwardingAddress) else deliver normally :) Thnx, -- Zeljko Culek IT Department Samurai Digital d.o.o.

[Dovecot] Index issue?
by IT geek 31 10 Dec '13

10 Dec '13

I've just hastily migrated from Dovecot 1.2.9 to 2.2.9 due to a disk crash. When I say hastily, I literally copied the user's mail data files to the new server and then started the Dovecot service. The trouble is, I now have a user who can see all the subfolders of her inbox in Outlook, but not on her iPad. Do I need to re-index her mail folders? The data is there (as seen by Outlook 2013) and is good, but the iPad mail client only sees the top-level folder. Any thoughts? -Mark

[Dovecot] Problem with INDEXes and deleting shared folders
by Achim Gottinger 10 Dec '13

10 Dec '13

Hi, I use dovecot 2.1.7 on debian wheezy. I have a bunch of shared folders whom i configured to store the indexe's under the users mail_location/shared/%%u. I configured acl's for those shared folders in an way that all users should be able to add and delete folders (for example "group=buchhaltung keilrwtsx"). Creating folders works fine but if i try to delete such an folder i get the following error. Dec 10 12:03:41 logon-zor dovecot: imap(ag): Debug: Can't rename 'shared/buchhaltung/Test' to 'Trash/Test': one namespace has index dir and another doesn't Of course there is no dovecot.index file in /home/vmail/buchhaltung/mai/.Test but there is one in /home/ag/vmail/mail/shared/buchhaltung/.Test and in /home/ag/vmail/mail/.Trash. Seems dovecot does not honour the shared namespaces index settings when trying to rename that folder. Is there an fix for this issue in 2.1.7 or would upgrade to 2.2.5 (from debian unstable) help? Thanks in advance Achim Gottinger Here are my namespace mail_location etc. settings: mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX mail_uid = 998 mail_gid = 998 first_valid_uid = 998 first_valid_gid = 998 mail_shared_explicit_inbox = yes maildir_very_dirty_syncs = yes namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { inbox = yes location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX prefix = separator = / type = private }

Hello, our dovecot mailservice was running smoothly for a long time.

[Dovecot] Question regarding quotas (is this a bug or intended behavior) ?
by Gilles Chauvin 09 Dec '13

09 Dec '13

Hi, I was wondering if this is a normal behavior (test was made using Dovecot v2.2.9). In my config, quotas are configured as follows: plugin { quota = dict:Userquota::file:%h/dovecot-quota quota_rule = *:storage=1G quota_rule2 = Trash:ignore } # doveadm mailbox status -u my_user "messages vsize" '*' Trash messages=4997 vsize=229535631 Drafts messages=0 vsize=0 Sent messages=0 vsize=0 Junk messages=0 vsize=0 INBOX messages=0 vsize=0 # doveadm -f flow quota get -u my_user Quota name=Userquota Type=STORAGE Value=0 Limit=1048576 %=0 Quota name=Userquota Type=MESSAGE Value=0 Limit=- %=0 The 4997 mails in the Trash mailbox are ignored as desired, but now, if I have the following case: # doveadm mailbox status -u my_user "messages vsize" '*' Trash messages=0 vsize=0 Trash/TEST messages=4997 vsize=229535631 Drafts messages=0 vsize=0 Sent messages=0 vsize=0 Junk messages=0 vsize=0 INBOX messages=0 vsize=0 (As you can see mails were moved to a Trash/TEST mailbox) # doveadm -f flow quota get -u my_user Quota name=Userquota Type=STORAGE Value=220918 Limit=1048576 %=21 Quota name=Userquota Type=MESSAGE Value=4997 Limit=- %=0 I tried to add the following quota_rule: quota_rule3 = Trash/*:ignore But this doesn't fix anything. Do you have any idea about why this is not working ? Thanks, Regards, Gilles.

[Dovecot] Use Replication plugin to do a backup (one-direction sync)
by Francesco Barresi 09 Dec '13

09 Dec '13

Hello, I have a setup where I need to have Server A (dovecot 2.1.7) replicated on a Server B (dovecot 2.1.7). I know that I can do a per user backup with: doveadm -D backup -u %u remote:mailmirror@serverB I would like to use Notify/Replication to backup only when there's something new. I don't understad if the Replication plugin can be used to do a backup server, or it's only of for two-way sync? My question is: It's possible to use Replication to do a backup (one-direction sync)? Thanks Francesco
