Re: [Dovecot] Understanding Sockets
Thanks Ben, I'm using an Ubuntu Server OS (10.04) and it seems that the latest package they provide is 1.2.9. Do you know if anyone has had any success getting a Dovecot 2 package on this Ubuntu distro and how they went about it (Not comfortable compiling sources at this point!!)?

What I wanted to clarify is my understanding the socket listen section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in Dovecot. The master socket is used for internal processes which is mainly dovecot-lda so that when Dovecot receives mail it knows where to deliver it and client is defined for external processes, for example Postfix who would use the info to determine if a user existed. Would you say this is a fair (albeit) dumbed down!!) synopsis of sockets and their purpose? Your mention of 'socket listen' and 'master' auth sockets suggests you are using Dovecot 1.x. That description is pretty-much correct for 1.x, however you should upgrade to 2.x as soon as you reasonably can, since 1.x is no longer supported. See http://wiki2.dovecot.org/Services#auth for a description of the socket types available with Dovecot 2. [The statement there that 'client' sockets can safely be exposed to the entire world, including over inet sockets, is not entirely true. AFAIK there is no rate limiting, so an exposed 'client' socket is a password oracle and should therefore be somewhat protected. The risk is approximately equivalent to an unshadowed password file, with the encrypted passwords exposed.] Ben
Re: [Dovecot] Non-dovecot user looking for feedback
God, that's ancient data for Cyrus. I should go update that. Cyrus 2.4.17 fails a couple of edge cases (searching for and some complex list-extended cases where we're not iterating both the mailboxes and subscriptions databases concurrently correctly). Cyrus git master only fails the list-extended. In other words, don't believe every wiki you read on the internet! Bron. On Tue, Dec 18, 2012, at 07:19 AM, Chris Ross wrote: Thank you for that. That mostly rules out Cyrus, as it seems much the lesser of Dovecot and UW-IMAP. But, it mostly just declares it's statements about accordance with the standards. While I appreciate that, I'm more interested in how it behaves with common mail clients. And, the note about dovecot Expunge Fetch says depends on storage, but gives no more information. What sorts of storage options are available, and what the pros and cons of them are, was one of my original questions. Is there some give me all the details to read through document somewhere? What it does, it's capabilities, and how it does things? Thanks again to all for any help. - Chris On Dec 17, 2012, at 07:48 , David Morsberger d...@morsberger.com wrote: Check out: http://imapwiki.org/ImapTest/ServerStatus -- David Morsberger 301-758-7387 Sent from my iPhone On Dec 17, 2012, at 2:00 AM, Chris Ross cross+dove...@distal.com wrote: I've been using UW-IMAPd for neigh on forever (at least since 2001). But, as it's basically stalled, and I'm about to update the hardware that is my mail server, I thought it was time to review existing open-source IMAP servers. Dovecot is the top three in my looking. The other of the top three candidates, because I know of people who've used it, is Cyrus IMAP. So, I should note that my thoughts are uw-imapd, because I already know how to use it, Cyrus, because someone I know/trust liked it years ago, and dovecot, because it seems stable, professional, and to meet all of my needs. I guess the biggest question I have is how files/folders are stored in the filesystem. uw-imapd has a mbx format that all of my folders are in, and also has support for mbox and maildir (i think). mbx had some advantages for speed access, which would be unimportant I assume with dovecot's indexes, but IIRC there was also some reason the mbox format coped poorly with multiple clients accessing the same folder at the same time. So, am I right that dovecot supports only the one big full file mbox format, and the maildir format? And if so, is it known to allow multiple simultaneous IMAP clients to access and monitor and/or modify the same folder simultaneously? After those questions, it's just a what do you think the pros and cons of each are? I know asking in this forum, that I will get most if not all votes for Dovecot. And that's fine, as long as you have specific reasons why it would be better for someone with only a handful of users and minimal time available to administer the systems in question. Thanks! I appreciate any and all feedback. - Chris -- Bron Gondwana br...@fastmail.fm

Google is your friend http://lmgtfy.com/q=POP+qmail+to+dovecot+migration The top hits provide exactly what you're looking for. 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized We migrated 5000+ from qpopper years ago. Dovecot is sooo much better on system load. Yes, locking and timeouts are in the config file. 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days That's not part of pop3, so no, it's not possible with dovecot alone. You could probably work out a plugin to move read mail after x days, or there may be one out there ? Or some imap robot could do it.. Ken A.

I'm a bit green around the gills with this kind of thing.

The old pigeonhole version is included in the dovecot*.diff of the ubuntu source package. Just untar the download from pigeonhole and replace the pigeonhole directory in the dovecot-$VERSION directory with the new pigeonhole directory from the download. In order to include current dovecot versions, you will need to run uupdate to integrate the new tarball into the package. See uupdate --help Then you can build the package as described in previous mails. Regards Daniel -- https://plus.google.com/103021802792276734820
