[Dovecot] 1.1.4 and trouble over NFS
by Igor Colombi 09 Oct '08

09 Oct '08

Hello, I have some trouble with the current setup (it's a testing environment): 2 server with Dovecot 1.1.4 from source (OS Debian testing 2.6.26) (name: "exim" and "exim2") 1 NFS server (OS Debian testing 2.6.26) I use NFS v.4, indexes shared over NFS. The relavant part of Dovecot configuration: dotlock_use_excl = yes mail_nfs_storage = yes mail_nfs_index = yes mmap_disable = yes lock_method = dotlock Maildir format. /etc/exports on NFS server: /mnt 192.168.0.0/24(rw,sync,no_root_squash,no_subtree_check,fsid=0) /mnt/vexim 192.168.0.0/24(rw,sync,no_root_squash,no_subtree_check) /etc/fstab on the clients: 192.168.0.71:/vexim /mnt/nfs1 nfs4 rw 0 0 When I access a mailbox with 2 different clients (for example Outlook Express that uses "exim" and Thunderbird that uses "exim2") and in the same time some message is delivered to the mailbox (the smtp is served by Exim 4.69) Dovecot has some trouble as you can see: *** Log from machine "exim" Oct 7 20:00:20 exim dovecot: IMAP(postmaster(a)minnie.tld):

safe. I can try to move indexes on the local disk, the trouble with dovecot.index disappear but I have again problem with dovecot-uidlist. I can reproduce this kind of problem easly: 2 clients on the same mailbox connected to two different imap server and a simple bash script that send 2 email every 1 second to the mailbox. There is some option/configuration that I can try to change?

[Dovecot] zlib plugin
by Luuk 09 Oct '08

09 Oct '08

hi, Could anyone give some info on this plugin? When i read the wiki (http://wiki.dovecot.org/Plugins/Zlib) i'm still left with some questions... I use Maildir to store my mails, if i enable this zlib-plugin, should i 'manually' compress all messages? or wil the uncompressed messages still be accessible by dovecot? wil new messages be compressed automagically? how should the compressed messages be named? a message now has the name '1223224520.2783_1.opensuse:2,S' how would a compressed message be named? ['1223224520.2783_1.opensuse:2,SZ' or '1223224520.2783_1.opensuse:2,S,Z' or ???] Last but not least, what gain will i have by using this plugin in combination with Maildir, or will it have more impact when mails are stored in mbox. -- Luuk $ dovecot --version dovecot version 1.1.1 $ uname -srpmio Linux 2.6.18.8-0.10-default x86_64 x86_64 x86_64 GNU/Linux

So now "Disable non webmail IMAP access" in vpopmail works fine!

[Dovecot] Folders within folders?
by ed beers 09 Oct '08

09 Oct '08

I'm trying to migrate my emails from an existing server (University of Washington IMAP toolkit) to dovecot. My clients are all using Thunderbird. I'm moving to a new Ubuntu based server (old one was Centos4) and selected dovecot solely because it was the default option. I'm not committed to it if it isn't the right tool for my application. My existing server allows hierarchical folders and these are used to organize 20 years worth of carefully sorted emails. I can create a new folders on the dovecot server but Thunderbird doesn't allow me to create new sub-folders within them. I think T-bird is configured OK since this works on the old server. Is this a dovecot limitation or have I configured it incorrectly?

[Dovecot] postfix/dovecot/mysql quotas not working, default dovecot.conf does.
by dovecot＠corwyn.net 08 Oct '08

08 Oct '08

I'm having problems getting dovecot to set imap quotas that are defined as individual quotas for virtual users using mysql. I'm using postfix/dovecot 1.1.3, just built from source about a week ago. I've been testing using telnet and getquotaroot. when I define the quota in dovecot.conf quota = dirsize quota_rule = *:storage=102400 I get the following response from Dovecot: # telnet 127.0.0.1 143 Connected to 127.0.0.1. * OK Dovecot ready. . login test222(a)example.com password . OK Logged in. . getquotaroot inbox * QUOTAROOT "inbox" "" * QUOTA "" (STORAGE 276273 102400) All is good (the mailbox IS currently very full as part of my testing). However, when I define that data in the dovecot-sql.conf file, it doesn't appear to pick the data up, either as an override, or, if I delete quota_rule = *:storage=102400 from dovecot.conf, I get no quota at all . getquotaroot inbox . OK No quota. # grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = MD5-CRYPT password_query = \ SELECT username, domain, password \ FROM mailbox WHERE username = '%u' AND domain = '%d' AND active = '1' user_query = \ SELECT 1015 as uid, 105 as gid, '/var/spool/mail/%d/%n' as home, \ 'maildir:/var/spool/mail/%d/%n/Maildir' as mail, \ 'dirsize' as quota, \ concat('*:storage=', quota, 'B') as quota_rule, \ FROM mailbox WHERE username = '%u' AND domain = '%d' and active = '1' the results remain the same in telnet. Any assistance would be appreciated. I've done a fair amount of digging, and have no idea why it's not working. ASsociated other configuration below. Thanks!

[Dovecot] Dovecot-sieve processing optimizations
by Roderick A. Anderson 08 Oct '08

08 Oct '08

I'm working at the next part of the virtual domains mail server. I'm moving this account (raanders(a)acm.org is a forwarder) which has a bunch of procmail rules to file into folders. My question is if it is more efficient is use? if { ... } elsif { ... } elsif { ... } else This seems to be the way many of the example scripts do it but I found at least one that used if { ... } if { ... } Which is more procmail like and for me reads easier. If not here where should I ask? Thanks, Rod --

Yes, that's what I was thinking when I wrote "workaround" in my first mail: On Wed, Oct 8, 2008 at 5:08 PM, Diego Liziero <diegoliz(a)gmail.com> wrote: >[..] >I think that this solution is more readable than the only workaround I >can imagine now (that is disabling global filtering and enabling it in >a pcre table for everything except that particular case). So it's a bit less readable, I've to remember to disable sender restrictions in the content filter return transport to avoid filter loops, there will be one more line for each mail in the log stating that the filter is triggered, but apart from that it should work as I need. Thank you to everyone that helped me, tomorrow I'm going to test both methods. Regards, Diego.
