[Dovecot] problem with folder creation
by John Watson 02 Nov '10

02 Nov '10

I am running dovecot 1.2.12 on Free BSD 8.1. We also have postfix and a version of squirrelmail for the UI. We are using MySql database to store the email account info. I wrote a script to insert about 100K users into mysql. Those accounts seem to work well and I'm able to see things like 'Drafts', 'Trash' and 'Sent'. Now I am working on code to create new accounts - one at a time. The accounts get created and I can send and receive email from them but when I go go Drafts, Sent or Trash I get an error that says: ERROR: Could not complete request. Query: SELECT "INBOX.Drafts" Reason Given: Mailbox doesn't exist: INBOX.Drafts When I go out and look at the mailbox folders for these users I only see "cur", "new", and "tmp" whereas on other accounts that work well I also see things like INBOX.Drafts etc. I have examined the sql that is inserting the accounts in bulk versus the one by one case and can not see any differences (other than a new mailbox name/password etc). Everything that I'm reading online indicates that Dovecot should just create these extra folders on the server and there is really nothing for either an admin or a user to do. Does anyone have any more information on this? Thanks in Advance John Watson

[Dovecot] Doveadm-Expunge v2.0.5
by Kui Zhang 02 Nov '10

02 Nov '10

Hello Few questions regarding Doveadm-Expunge. 1. I have lazy expunge configure with this name space: .EXPUNGED Storage type: mdbox doveadm -Dv expunge -u user@domain mailbox ".EXPUNGED/*" savedbefore 7d I get some interesting outputs. doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=791 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=792 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=793 .... doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=196, msgid=<E1OwJm4-0000j4-1l@domain>, size=1856 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=197, msgid=<E1OwJmP-0000pr-4M@domain>, size=1756 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=198, msgid=<E1OwJpP-0002Hp-Pu@domain>, size=1810 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=199, msgid=<E1OwJqw-0002y7-AF@domain>, size=1766 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=200, msgid=<E1OwJud-0004ba-Fe@domain>, size=1890 ... So what is the diff between "Debug: expunge" and "Info: expunge". Anything done to "Info: expunge"? I am assuming the "debug: expunge" are the only entries with actions. And "Info: expunge" is not doing anything. I ran doveadm purge -u user@domain after. I did not notice any missing emails. Sorry for the trivial question, I just want to make sure not mail would disappear, all of sudden. 1.A. Would not it be faster not to enumerate for large mailboxes (30-40GB - Maildir)? Is it possible to add a switch, to select single user expunge behavior? ref: http://www.mail-archive.com/dovecot@dovecot.org/msg32322.html 2. Also. expunge does not appear to remove empty mailboxes, is this a bug or intentional? If intentional, why? Any way to automated removal of empty mailboxes? Thank you KuiZ

[Dovecot] Maildir and Index max size
by Emmanuel Gonzalez Carmona 02 Nov '10

02 Nov '10

Hi all, I was wondering if any of you had configured a Mailbox with >= 5GB of space with LDA indexing enabled on it. I'm trying to understand the limits to Dovecot (if there are any) regarding maildirs/indexes max size. Reading in the documentation i didn't found anything concerning this issue. Any experience with this? Emmanuel Gonzalez Carmona

[Dovecot] Differences between IPv4 and IPv6 authentication
by Tony Meyer 02 Nov '10

02 Nov '10

Hi, I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? For example: ~$ telnet server1.teststable.simplyspamfree.com 143 Trying 2a01:4f8:100:12c1:bc:28:b2:34... Connected to server1.teststable.simplyspamfree.com.

[Dovecot] fts_solr on debian lenny dovecot 1.2.15
by a＠test123.ru 02 Nov '10

02 Nov '10

Hello, I cannot run FTS SOLR engine. OS is debian lenny. I re-compiled debian package (from backports) with --with-solr option. Dovecot loads fts_solr plugin. I know that it loads plugin because if I remove lib21_fts_solr_plugin.so, dovecot does not start. But it does not attempt to communicate with SOLR. Simple check: stop solr tomcat, and open 8080 port in netcat: $nc -l -p 8080 dovecot never tries to connect to 8080 when I search message by IMAP. I removed indexes, it did not help.

[Dovecot] Problem with excel and word attachements ?
by Frank Bonnet 02 Nov '10

02 Nov '10

Hello We are in (random) troubles with some emails that contains word and excel attachements ( others attachements are OK ) I don't really think Dovecot is implied in this trouble but I want to be sure ... The problem is users cannot open attachements from their clients ( thunderbird 3.1 ) it stays in "download" mode until timeout. Maybe there is a Dovecot's workaround to solve that boring problem ? Thank you
