[Dovecot] daemontools
by Rick Romero 05 Aug '06

05 Aug '06

Hi, I just started running RC2 on Thursday. I migrated an old Courier IMAP server, and the only issue I had was that I didn't understand how to enable quotas :) It's impressively fast, and I'm quite happy with it so far. This morning I found that dovecot had crashed, I had exceeded FreeBSD's kern.maxpipekva Has anyone successfully run dovecot under daemontools? I got it to fire up, but it didn't seem to work right.. I'm guessing it's a rights issue, but I haven't delved into it at all. Thanks! Rick

[Dovecot] Dovecot proxy in front of UWash?
by Vincent Fox 05 Aug '06

05 Aug '06

Is it possible to use Dovecot frontends in front of UWash backends? I need a proxy pool ASAP. There is not sufficient time to migrate the backends for 40,000+ users so they have to stay UW for now. I have been looking at Perdition but concerned about performance under load. Dovecot looks really promising with it's non-forking mode. I need simple dumb frontends no local mail. Other questions: 1) Database? Wiki only talks about SQL, can I have it map username to hostname using LDAP or some other mechanism? 2) Kerberos? I am hazy here, but can I have the frontends auth the user via Kerberbos and things "just work"? Or do I need to stick with PLAIN authentication? 3) Port mappings? Can I have the requests coming in on SSL ports remapped to non-SSL ports on the backends? Thus the backends could have their load reduced somewhat. e.g. client->proxy:993->backend:143

by Chris Cappuccio 05 Aug '06

In postgresql you can do something like select 'maildir:' || maildir as mail, uid, ... through dovecot-sql.conf Is there a mysql equivalent for adding 'maildir:' as a prefix to the 'mail' location ?

[Dovecot] Thunderbird and hanging "Copying message to Sent folder..."
by M.-A. Lemburg 04 Aug '06

04 Aug '06

Here's a work-around for the problem that appears to work and maybe also hints at the root of the problem: If you setup the Thunderbird account to "Place a copy in:..." "Other" and then select the Sent folder of the account (rather than just selecting "Sent Folder on: ..."), the problem appears to go away. I can't tell for sure, but Thunderbird seems to send the copy using a different connection than the one used for sending the message itself if you set things up in this way. The email still gets copied to the same Sent folder, so there's no change there. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Aug 03 2006) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! ::::

[Dovecot] Stale imap processes
by Fran Fabrizio 04 Aug '06

04 Aug '06

Anyone have any theories or experiences as to why for a certain user, some of his imap processes hang, and stay around for days and days? He just reported that his Thunderbird was timing out when trying to open folders, I looked on the server, and he had 3 old imap processes from 1 week+ ago. I killed those and his performance immediately improved. He checks mail with Thunderbird > 1.5 from both Win and Linux, Squirrelmail webmail, and pine. Of those, pine is the only one that is somewhat rare around here - any specific problems with pine's imap client code that anyone knows about? We have been using the dovecot-1.0-0.beta2.7 rpm for Fedora Core 5, I'm updating to 1.0-0.beta8.2.fc5 to see if that helps, as well. Just curious if anyone else has seen this lately.

[Dovecot] RC5 Outlook POP3 problem
by DNSExit Com 04 Aug '06

04 Aug '06

We have been using dovecot v1.0 alpha3 for almost 1 year for our mail hosting. It was running great until more accounts added to the hosting. I have been trying to upgrade it to v1.0 rc5 and we have found that the RC5 has problem with Outlook (Express) with POP accounts. We are getting error with POP3 on Outlook Express: Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'box5.dnsexit.com', Server: 'box5.dnsexit.com', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F Do you know if this is a bug or it is our configuration problem? I tried it on Thunderbird and it works great. Both Outlook and Outlook express fail. Are there anyone getting the same problem?

[Dovecot] Dovecot IMAP and Mac OS X Mail.app
by Ronny Adsetts 04 Aug '06

04 Aug '06

Hi All, I recently switched our Courier IMAP server over to Dovecot primarily for performance reasons. Server OS is Debian Sarge with Dovecot packages from backports.org (v 1.0.rc2-1bpo1). Access from Thunderbird and Horde worked fine with some shared folders defined and the Courier compatibility private folder stanza. Initial testing with Mail.app showed that, although the folder listing was fetched correctly including all shared folders, no mail could be viewed with Mail.app timing out with an error about invalid namespace. (I'll post the exact error message as a follow up when I can test again later). After searching the mailing list for a while, I came upon a message suggesting adding a second private namespace like so: namespace private { separator = . prefix = "INBOX." inbox = yes hidden = no } namespace private { separator = . prefix = inbox = yes hidden = yes } Now, this does work in a fashion and allows Mail.app to access the folders and mail. Problem with this config: * Mail.app displays all INBOX. folders at the top level *and* below Inbox * Thunderbird displays a spurious INBOX folder in the folder listing under Inbox. * Horde displays folders at the top level and below Inbox. Whilst not being a huge problem for our internal mail server, this is not optimal. Has anyone else had these or similar problems and managed to work them out? If so, how did you configure Dovecot or the clients to all play nicely together? I'd quite like to roll Dovecot out on our client mail server but I need to work this out first so any help is appreciated. Thanks.
