[Dovecot] What's the difference between mbox and maildir
by Andrew Falanga 08 Jan '08

08 Jan '08

I'm a little confused about some of these terms. What is: .imap/.imap/ (other than directories) mbox INBOX (I think I have this one) maildir ??????? I'm not sure how all of these things work together. Thanks, Andy

[Dovecot] Please help me resolve why mail isn't being delivered to virtual users
by Andrew Falanga 08 Jan '08

08 Jan '08

follow up: I forgot to mention, that I discovered my system doesn't appear to have procmail on it. So, I'm not sure what must be done for delivery of mail concerning that "LDA/Sendmail" dovecot WIKI page. Andy

[Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Esther Schindler 07 Jan '08

07 Jan '08

One of the key points that came up when I researched and wrote the "Five Things CIOs Should Know about Fighting Spam" article (http:// www.cio.com/article/28830) was that they should know the basics of how email works. Otherwise, said plenty of techies, the CIO won't have the first idea of what the email admin is complaining about. So I'm going to do my part. I'm going to write an "ABCs of Email" article (to accompany the many other ABCs articles we have on CIO.com, at http://www.cio.com/article/40242 ). I'd like your input on the topics that should be included, keeping in mind the fact that the target reader is a CIO, IT manager, or someone who wants to understand the basics, *not* actively get involved in email management. You don't need to write an essay for me or inundate me with links (though hey, if you want to make my life easier I shall not complain). What I'm looking for, primarily, are the categories of information that I should cover. In other words, if your CIO had an email ephiphany and asked you to give a half-hour presentation, what would you include? This won't be an "Expert says..." article nor will it be "Geek on the street says...." I intend to compile and research the "least you need to know" for the not-necessarily-techie bosses out there. And hopefully the end result will be that you have one less dumb question to deal with in your life. So: any suggestions? (You can reply privately if you prefer.)

Apple Mail has an option, "Automatically synchronize changed mailboxes" which I do NOT have checked so the problem must be within Apple Mail as you surmised. In fact, Apple Mail is now displaying public/INBOX in it's list of mailboxes even though it hasn't been created under ~/Maildir/control/ public G518X2:~/Maildir/control/public root# ls -la total 8 drwx------ 5 bb admin 170 Jan 6 10:20 . drwx------ 3 bb admin 102 Jul 28 22:38 .. drwx------ 4 bb admin 136 Jan 6 09:54 .HAM drwx------ 4 bb admin 136 Jan 6 10:10 .SPAM -rw------- 1 bb admin 9 Sep 9 07:06 subscriptions ...and INBOX in not listed in 'subscriptions'. Sorry for the goose chase, unless you like goose, of course :-) B. Bodger

[Dovecot] v1.1.beta13 released
by Timo Sirainen 06 Jan '08

06 Jan '08

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz.sig Changes since beta12: - Half of LDAP code was rewritten to fix reconnect/queuing problems. I did test that the new code works with and without auth binds, but be careful. - \Recent flags should finally work correctly with maildir. - last_used field wasn't updated for cache fields that were permanently cached. This caused them to be dropped after a month. TODO for RC1: - When pipelining commands, do only one sync after all of them. Besides improving performance, this fixes some rare problems when multiple commands are running simultaneously. - SEARCH/SORT: Replace invalid input with unicode "replacement character" instead of just skipping it. - Squat: Handle expunges. NFS support. - Fix Lucene support.

Can Dovecot do this automatically when it creates these directories? (/var/mail/apps, /var/mail/apps/domain.com)

[Dovecot] Upgrading a live running dovecot - how?
by Daniel Watts 06 Jan '08

06 Jan '08

Hi Guys, This has bitten us twice now. We're running Gentoo and emerge (ie compile) a new version of Dovecot thinking we can finish that then restart Dovecot in our own time. It seems that Dovecot immediately starts to use the newly compiled Dovecot binary and we get version mismatch errors preventing access. Would be good if Dovecot behaved in such a way that it kept on using the old version (held in memory) until it was restarted where it then loaded the new version. Dan

I am trying to debug some core dump problems. I should be able to run imap by itself right? How to fix? # ./imap imap(root): Fatal: setgroups() failed: Too many extra groups I am using latest nightly code.
