[Dovecot] horde sync status ?
by Spyros Tsiolis 05 Oct '12

05 Oct '12

Hello all, I had a quick look at the horde site and noticed that horde is being advertised as, let's say, "smartphone friendly". Does anyone know if the newest horde version can "talk" to smart phones in regards to e-mails ? In other words, can a user owning a smartphone get his/her e-mails on it apart from the webpage ? Thank you, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] bug formatting results when using doveadm-server
by Angel L. Mateo 04 Oct '12

04 Oct '12

Hello, I have a infrastructure using director in front of backend servers. So I normally run doveadm commands in director servers, not the backends. The problem I have is when I try to concatenate commands like this: doveadm search -S /var/run/dovecot/auth-userdb -u ${user} SAVEDSINCE 5w | while read guid uid; do doveadm fetch -S /var/run/dovecot/auth-userdb -u ${user} size.physical mailbox-guid $guid uid $uid; done The problem is that although when I run doveadm search command in … [View More]

[Dovecot] possible nfs issue
by Cor Bosman 04 Oct '12

04 Oct '12

Hi all, we've started receiving complaints from users that seemingly use more quota than they actually have. We noticed that these users have (in some cases many) .nfs files in their mailspool. Some of our admins checked their own dirs, and noticed them there as well. This could of course be unrelated to dovecot (kernel issue, netapp issue) but maybe somehow has an idea about if dovecot could cause this. This has been going on for at least a year, not really enough to notice before now. root@… [View More]

[Dovecot] LDA vs LMTP index files
by list＠airstreamcomm.net 03 Oct '12

03 Oct '12

In the docs it states that LDA " ...takes mail from anMTAand delivers it to a user's mailbox, while keeping Dovecot index files up to date." I am wondering if LMTP also interacts with the Dovecot index files and keeps them up to date?

[Dovecot] [PATCH] Add SCRAM-SHA-1 password scheme
by Florian Zeitz 03 Oct '12

03 Oct '12

Hello, attached is an hg export on top of the current dovecot-2.2 branch, which adds support for a SCRAM-SHA-1 password scheme. Ideally I'd want doveadm pw's rounds flag to apply to this, but that's currently specific to the crypt password scheme, so I left it out for now. Regards, Florian Zeitz

[Dovecot] Spurious " Renaming not supported across conflicting directory permissions"
by tlhackque 02 Oct '12

02 Oct '12

Dovecot 2.1.10 Client = Thunderbird. Local disks. mbox format. Attempted to rename a folder, failed with: CANNOT Renaming not supported across conflicting directory permissions I don't understand why this should happen. o I was renaming within a directory - the attempt was to rename "Domain Names &- SSL Certificates" to "Domain Names". No directory was specified o The reason the directory has g=s is for dovecot - so that the 'mail' group (12) will stick to any files … [View More]created. I was getting more understandable permission failures before I added it. Since 's' doesn't apply to files, I don't see why this should be viewed as a conflict. o If I chmod g-s the directory, the command succeeds.
