Re: dovecot 2.0?

What's your Linux/BSD distribution name and release version?
iRedMail will install Dovecot-2 on several distributions, includes:

- RHEL/CentOS/Scientific Linux 6.x
- openSUSE
- Ubuntu 11.10, 12.04 LTS
- Gentoo
- FreeBSD
- OpenBSD

So only few distributions and releases stays on Dovecot-1.2:

- RHEL/CentOS/Scientific Linux 5.x
- Debian 6

You are totally right. http://wiki.dovecot.org/PrebuiltBinaries  .  Curious if anyone has used "testing" repos and had any success. Could be a long long time before its in "stable" . Is dovecot 2.0 really that different from debian 6 to Ubuntu 11.10, 12.04 LTS ?

Thanks for the discussion.

Re: dovecot 2.0?

I know there has been a lot of bug fixes and that sort of improvements to 2.0. I was really looking to try dsync as I have been having difficulty migrating a Kerio 6.5 mail server mail via imap. When trying to see if dsync was an option i figured out dovecot had that feature in the 2.0 later version.

I'v been having limited success using imapsync to migrate mail. I get all the mailboxes from Kerio, but Inbox. It doesn't map right to the postfix/dovecot maildir, and I do know there is some mapping commands. I just haven't figured that out yet. I'm real close but so far away if you know what I mean.

My inquiry about debian and dovecot 2.0 is all from having this migration problem. And I'm pretty new to postfix/dovecot. Any help you could offer would be wonderful. Much thanks.

Re: dovecot 2.0?

How about setup one more iRedMail server with the distribution which provides Dovecot-2, e.g. a virtual machine in VMware/VirtualBox/Xen/KVM/etc, then try dsync. if it works, try to copy this migrated mailboxes to your Debian server. It works again, migrate all mailboxes if you want.

Re: dovecot 2.0?

Hi,

I installed the dovecot 2 in debian (squeeze) from backports packages, and I modified in IREDMAIL_INSTALL_DIR/conf/dovecot   this line
export DOVECOT_VERSION='2'  (from 1 to 2)


add  http://backports.debian.org/debian-backports squeeze-backports main   to  /etc/apt/sources.list  and install dovecot-imap dovecot-pop3d  with this command  : aptitude -t squeeze-backports install  dovecot-imapd dovecot-pop3d

For me, I installed before launching install script (iRedMail.sh)  --  I think if you don't install it before, it will cause dependencies problem with the squeeze packages

aptitude -t squeeze-backports install dovecot-mysql dovecot-imapd dovecot-pop3d dovecot-common dovecot-sieve dovecot-core dovecot-managesieved

I seems that it works
