[Dovecot] Dovecot 2.0 in Active-Standby configuration
by Yaron & Hani Nahum 07 Mar '11

07 Mar '11

Hi, I am planning to use Dovecot 2.0 as a Mail server for a Voicemail system. There is not much traffic so I am not concerend about scaling. However redudancy is an issue. I need to have two Dovecot servers installed on two different farms and setup HA between the two. I would prefer that the HA would be automatically. I have two different storage machines with SAN, and I can setup Layer 2 between the two farms. I am concerned with split brain scenario where the two farms are disconnected and both machines would become active. What cluster configuration would you recommend for such an enviroment?

[Dovecot] Problems with shared folders with Dovecot 1.2.12
by Pašek Ladislav 07 Mar '11

07 Mar '11

Hello, I'm trying to run shared folders with Dovecot 1.2.12. I'm managing ACLs from SOGo and it seemd that it successfully create dovecot-acl and dovecot-acl-list in user maildir. But I cannot see any of these shared folders. In Thunderbird I could see shared folder in Subscriptions but without option to subscribe. I was reading almost everything that was possible to google but without success. My config: [root@mail etc]# dovecot -n # 1.2.12: /etc/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5 x86_64 CentOS release 5.5 (Final) xfs base_dir: /var/run/dovecot/ log_path:

[Dovecot] v2.0.11 released
by Timo Sirainen 07 Mar '11

07 Mar '11

http://dovecot.org/releases/2.0/dovecot-2.0.11.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.11.tar.gz.sig Looks like v2.0.10 was a bit troublesome release. I expect this one to last longer. * dotlock_use_excl setting's default was accidentally "no" in all v2.0.x releases, instead of "yes" as in v1.1 and v1.2. Changed it back to "yes". - v2.0.10: LDAP support was broken - v2.0.10: dsyncing to remote often hanged (timed out in 15 mins)

I've got a Samsung Captivate running K-9 Mail. It could definitely have some bugs. Sometimes if I delete a message on my phone, I'll see it show up in the Trash folder but not disappear from the folder it was deleted from. It's just not consistent. but it is better than it was before. I'll look in the logs and see if I see anything interesting. Thanks again,

[Dovecot] Multiple Concurrent IMAP Connections For Same User
by Nigel Webber 05 Mar '11

05 Mar '11

Hi I've been using courier for some time, but have just built a new box and am using dovecot (V1.2.9), Ubuntu 10.04LTS. I have a question regarding multiple concurrent imap connections and how to get dovecot to behave in the same way that courier does. I have searched the wiki, but find little relevant to my specific issue. Courier-Imap Behaviour If I have thunderbird pointed at the 'Inbox' folder via IMAP, then connect another IMAP client to the same mail account (in this case an iPhone), and then delete an email using the iphone, then after a couple of seconds, the inbox shown by Thunderbird updates, removing the now deleted email. It does this without my having to touch Thunderbird. Dovecot behaviour Performing the same test on a different mailbox, this time hosted via Dovecot, I again see the two views, one in Thunderbird and one on the iPhone, but when I delete the email on the iPhone, the change is not reflected in the view on Thunderbird. If I select the email on Thunderbird, then it has no content. If I restart thunderbird, the deleted email is still shown. I have to delete (the already deleted) the email also in thunderbird before it finally dissapears. How can I get the courier behaviour where the inbox in one email client automagically reflects the changes made to that inbox in another client? If I am better sticking to Courier to get this functionality, thats fine, but if I can configure the behaviour I desire and still retail the benefits of dovecot then thats even better! Kind Regards Nigel

[Dovecot] deleted messages not going away in Thunderbird?
by Dave McGuire 05 Mar '11

05 Mar '11

Hi folks. This may be a dumb question, but I can't seem to find a clue. I'm running Dovecot v1.2.9 and Thunderbird v3.1.7. If I delete messages using a different IMAP client (I also use an iPhone and occasionally SquirrelMail), I would expect those messages to disappear from Thunderbird the next time I start it or click on "Get Mail". In fact, they do...most of the time. Sometimes, however, they just stick around. If I do a "Repair Folder" on the inbox in Thunderbird, the messages go away. Is this a known issue? My gut tells me there's some Thunderbird option to make it follow inbox contents with more "attention" but I've not been able to find it. Thanks, -Dave -- Dave McGuire Port Charlotte, FL
