I prefer Gentoo due to its 'rolling release' nature (mine has been kept up to date from day one for the last 5 years, with not one major glitch - knock on wood). I keep the 'system' pinned at stable, and keyword the fast moving packages to unstable... accomplishes the same thing, except that most of the critical packages I use are updated to latest versions within hours or days (with some irritating exceptions, like Samba), as opposed to weeks or months like most other distros.

Re: [Dovecot] Strange Dovecot Issue with 64-bit AMD Processor
I'm at a disadvantage here. I'm more of the end user than admin, but I cope. But if someone wanted to assist me in maybe trying this again -- perhaps with the latest stable version -- I'd be interested in another test.

The expire database is empty, so it has nothing to do. Expire plugin updates the database while messages are being saved/copied to the expire mailboxes.

I then reran dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool I still get no events in /var/log/messages, and my Spam messages from Jan 22 are still there. On the bright side I do have an expire.db file now with data in it, tho I can't quite figure out what makes it update. shouldn't the messages > 14 days old (the date I have set in.conf) go away?

What were you using for webmail again? Squirrelmail, using the same imap server as a back-end. Nothing special happens to the emails in question. The mail store is Maildir++, and the message files don't change. They are moved from new/ to cur/, and the Seen flag is added, but that's something that happens all the time and works fine. Except for some strange cases, but I doubt that has anything to do with the Seen flag. Outlook seems to be seeing a Deleted flag which obviously isn't there. Maarten

So you prefer to use the new&shiny versions of the software that include all new&shiny bugs? Given my experience with a lot of software, that's just not an acceptable policy. Not everything is as bad as Microsoft software, which usually needs at least Service Pack 1 to operate normally, but in general, bleeding edge isn't the way to go. For production environments, I'm more than happy with Debian Stable plus backports versions of things like dovecot. That way I don't have to worry about upgrading every single package by hand when (not if) security updates have to be applied, and still have the advantage of running a close-to-bleeding-edge version of packages like dovecot. Without having to do much about it when new versions come out. If they prove to be good enough for unstable and testing, I can grab them and use them.

I think the user either A. deleted the emails sometime ago and forgot or b. They didnt get moved over from the old mailserver when it crashed. The user said that they should have emails from 2004, but I couldnt find any newer than Jan. 2007.

Re: [Dovecot] Smooth mailbox to maildir migration

I need to move all of them to maildir, to take advantage of IMAP subfolders that do not work with mbox format (so I'm told :). Of course I cannot safely stop the service for more than a bunch of seconds... What I'm about to do: create a second dovecot instance to cope with imap client configured for maildir (and possibly pop3 on another port for those using both), which means a dovecot launched with -c /path/to/alternate.conf and a new /etc/init.d/dovecot2-theRevenge having the proper -i option given to startproc in order to make it ignore the other instance. for each user: convert the mailbox with some sort of mb2mb (which is the better one?) create a .procmailrc with a proper DEFAULT= bearing the magic trailing slash indicating maildir to procmail for each converted user. And I'm done... Have I forgotten something? Is there a better way? I do all migrations with perdition (imap proxy) It is very simpe to configure and rock solid. So you can make perdition listen on 110, dovecotA listens on 111 and dovecotB listens on 112. A text file tells who is on which server. With this setup you can even migrate into the same directory from mbox to maildir. Any one else tryed such a thing? Cheers to all, luciano. cheers, dirk
