[Dovecot] Restoring older messages to new server?
by Voytek Eymont 10 Jun '12

10 Jun '12

I had Dovcot 1.x setup, all was working well (till...) Server got stuffed up and same Dovecot 1.x was rebuilt, put back in service, all's working well. I have recovered data from Maildirs messages from the old server, As some of the inboxes now have new messages, what is correct way to copy older messages from old server to new server ? (There are no duplicates, simply old messages from past server, data is physically on new server) Thanks for pointers, Voytek -- Swyped on my Motrix with K-9 Mail. Please excuse my brevity.

[Dovecot] Dovecot setup fails w. multiple mail locations (gnus/dovecot/offlineimap)
by Johnny 10 Jun '12

10 Jun '12

Hi, I am trying to setup a Gnus - Dovecot - Offlineimap - Webmail (Gmail / Fastmail) chain and cannot configure the correct behaviour. Any advice to get this working properly would be very appreciated! I have set up Offlineimap to synchronise two mail accounts into separate folders under ~/Maildir. After running Offlineimap, the folders look as below. Maildir/ |-- Gmail | |-- cur | |-- dovecot.index.log | |-- dovecot-uidlist | |-- dovecot-uidvalidity | |-- dovecot-uidvalidity.4fd3b80e | |-- [Gmail].All\ Mail | |-- [Gmail].Drafts | |-- [Gmail].Important | |-- [Gmail].Sent\ Mail | |-- [Gmail].Spam | |-- [Gmail].Starred | |-- [Gmail].Trash | |-- INBOX | |-- new | |-- Personal | |-- Receipts | |-- tmp | |-- Travel | `-- Work `-- Fastmail |-- cur |-- dovecot.index.log |-- dovecot.mailbox.log |-- dovecot-uidlist |-- dovecot-uidvalidity |-- dovecot-uidvalidity.4fd3b75e |-- INBOX |-- INBOX.Drafts |-- INBOX.Sent\ Items `-- INBOX.Trash The Dovecot config is below. (I have set up a blank "MailTest" directory as inbox, believing that this may preserve the two imap directories better for offlineimap synching (not sure if this is correct)). ,---- | mail_location = maildir:~/Maildir:LAYOUT=fs | | namespace inbox { | location = maildir:~/MailTest | inbox = yes | } | | namespace mygmail { | type = private | separator = . | prefix = "mygmail." | location = maildir:%h/Maildir/Gmail/:LAYOUT=fs | inbox = no | hidden = no | list = yes | subscriptions = yes | } | | namespace myfastmail { | type = private | separator = . | prefix = "myfastmail." | location = maildir:%h/Maildir/FASTMAIL/:LAYOUT=fs | inbox = no | hidden = no | list = yes | subscriptions = yes | } `---- Accessing dovecot through gnus with this setup only sees the files in the directories that are not prefixed (e.g. under Fastmail, INBOX is the only seen folder, all INBOX.subfolder are not there). Removing the prefix manually they can be seen again however (e.g. INBOX.subfolder -> subfolder). If I remove LAYOUT=fs in the dovecot config, nothing is seen at all, although the directories look like proper Maildirs! A second issue is that running Offlineimap a second time seems to work ok for gmail, but Fastmail complains that "cannot create directory '.'"? Thanks! -- Johnny Dovecot 2.1.6 Offlineimap 6.5.2.1 Ma Gnus v0.6

Hello! I am wonder if there are plans to include backend health monitoring feature to Dovecot Director ? Yes, I'm aware of poolmon by Brad Davidson but I think it's kind of must-have feature out of box. thanks

[Dovecot] Upgrading 1.2.17 -> 2.1.x
by Adam G Tilghman 10 Jun '12

10 Jun '12

We're planning to upgrade our site from 1.2.17 to 2.1.x within the next few months, but we must ensure our ability to revert to 1.2.17 if problems arise. I don't expect our maildir storage would present a problem, but am less certain about 2.1.x index/control files remaining readable under 1.2.17. Should I have any reason to worry? -- Adam Tilghman Systems Support / Academic Computing & Media Services agt(a)ucsd.edu 858-822-0711 University of California, San Diego

[Dovecot] Deliver quota-warning via director
by Daniel Parthey 10 Jun '12

10 Jun '12

Hi there, I'm using NFS with Dovecot 2.0.20 and would like to deliver a quota warning to the user using the LMTP director. I have configured quota warnings according to http://wiki2.dovecot.org/Quota/Configuration But it seems that lda delivers the mail directly to the local filesystem and is not using our lmtp director, which prevents NFS mailboxes from getting corrupted. Is there a way to tell lda to use LMTP or the director and ignore the quota while delivering the notification? Regards Daniel

[Dovecot] Dovecot 1.x on AIX -> Dovecot 2.x on Ubuntu
by root＠yuma.acns.colostate.edu 10 Jun '12

10 Jun '12

We are working on migrating Dovecot 1.2.17 running on AIX 5.3 (believe it or not!) to Dovecot 2.0.13 running on Ubuntu. We have hundreds of users mboxes we will be migrating. My question is regarding the index files. Should we remove those after the migration, but before we open it up to users so Dovecot can create new ones? I did a test migration of a single user, and Dovecot detects the architecture change and put out some panic errors, corrupt files and backtrace messages in syslog on Ubuntu. The messages are shown below. If every user is going to generate these types of errors, I'm thinking maybe it makes sense to remove all the .imap directories and let Dovecot create new clean ones. I realize that may slow things down for awhile while Dovecot is rebuilding new files. Thanks for any info.

Hello!

[Dovecot] director and doveadm server
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hi, I've been reading doc at http://wiki2.dovecot.org/Director to configure my servers. My question is regarding configuration of doveadm server. I have configured both, director and backend servers, as described in that doc, but I don't know how to run doveadm commands in director servers. doveadm is working, because I can run commands, but they are executed in local (director) server. For example: root@myotis40:/etc/dovecot/conf.d# doveadm director status mail server ip vhosts users 155.54.211.169 100 1 but doveadm who seems to be executed just in local: (backend server) root@myotis30:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) angel.luis 2 imap (11931 11936) (155.54.67.5) (director server) root@myotis40:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) And another question about this... what is the local config option? I haven't found it documented anywhere. -- Angel L.

[Dovecot] director and IPs shown at the backends
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hello, I am configuring a dovecot imap/pop servers with a dovecot director in front of them. Because I am using director proxy, connections in the backends are show as coming from director IPs. Is there any way to configure director (or backends) so the backends know (and report) the original IP instead of the director IP?

[Dovecot] Corrupted mdbox on LMTP director delivery while user is logged in via IMAP
