Reprocessing MDBOX account to reduce m.* file count
by Ricardo Branco 14 Dec '16

14 Dec '16

Is there a way to force dovecot to reprocess a user account to refile the m.* files based on new config for max file size. Ive got one account at 22k files due to a 2M split.

mailboxes and capitalisation
by Thorsten Hater 14 Dec '16

14 Dec '16

Dear all, I have set up a series of special-use mailboxes in the default namespace differing by capitalisation of the names, mainly to capture multiple mailboxes with autoexpunge namespace inbox { ... mailbox Trash { auto = no autoexpunge = 30d special_use = \Trash } mailbox trash { auto = no autoexpunge = 30d special_use = \Trash } ... } However, doveconf -n reports only one mailbox, namely the second (lowercase t) and autoexpunge does not trigger for the first one (capital T). Removing the special use flag has no influence. namespace inbox { inbox = yes list = children location = ... mailbox trash { auto = subscribe special_use = \Trash } ... prefix = INBOX. separator = . subscriptions = yes type = private } Is this the intended behaviour? The example 15-mailboxes.conf seems to indicate otherwise and I would prefer the ability to set autoexpunge for both Trash and trash. (dovecot 2.2.26 built from source on Debian 8.0) Best regards, Thorsten

Simple way to get mailbox size by folder.
by Vijay Sarvepalli 13 Dec '16

13 Dec '16

Is there a simple way to get each mailbox size using dovecot's IMAP interface? The GETQUOTAROOT and GETQUOTA seems to work with the full maildir size and not the individual folders. I am finding a simple way for the webmail client to show usage of each folder. Thanks Vijay

Heloo, please I need "replicate" dovecot / dsync.

FTS solr info
by Brad Koehn 11 Dec '16

11 Dec '16

Are there updated instructions on setting up FTS with solr? I’m in the midst of upgrading my site and the links don’t appear to work or be applicable to current versions of solr. I grabbed 6.3.0 from apache and the instructions are no longer working, e.g., there’s no `solr/conf/schema.xml` file to replace; the `start.jar` has moved, etc. Just wondering if there’s somewhere else I should look, or if I should just hack it together on my own. Thanks! Brad Koehn

doveadm-server uses 100% cpu and never finishes, dsync backup also never finishes
by Patrick van Zweden 09 Dec '16

09 Dec '16

Hi Guys, I have a quite interesting problem. I have two servers that replicate to each-other. Suddenly one of the accounts is starting to eat a very large amount of disk space on, what basically is the replica for this account. doveadm-server seems to hang and keeps on filling the disk. I came across this message in the logs: Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: pool_system_malloc(6291528): Out of memory Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: master: service(doveadm): child 883 returned error 83 (Out of memory (service doveadm { vsz_limit=256 MB }, you may need to increase it) - set DEBUG_OUTOFMEM=1 environment to get core dump) I’ve increased the vsz_limit to 5G so it has stopped complaining. Only… the process never seems to finish. I’ve tried to export the mailbox using dsync: dsync -Dv backup -u 'xxxxx' sdbox:/tmp/patrick_export/ However this process never finishes either. It looks like it stays in one of the mailboxes and keeps on trying to copy messages. Format of the mailbox is sdbox Version of dovecot on all servers: 2.2.9 Any pointers for solving this problem? Kind regards, Patrick -- Patrick van Zweden
