Make sure your acl file ends with LF (there is an empty line at the end) otherwise dovecot doesn't read the last line.

[Dovecot] How to prevent SQL injection
by Jochen Schulz 31 Jan '07

31 Jan '07

Hi, on my way home today I thought a little bit about my setup which involves user and password lookups in an SQL database (Postgres). I asked myself whether I need to do anything to prevent SQL injection via forged user or domainnames. In the wiki I didn't find anything specific, only http://wiki.dovecot.org/Variables which mentions that there is the %E modifier which escapes single quites and backslashes. This appears to be a good idea but I am asking myself whether I need to do this since it is not mentioned anywhere. Is anybody able to comment on this? And BTW, it appears that one can use several modifiers at once. This is only implicitly mentioned in the wiki (You can apply modifier*s*), but it appears to work.

Perhaps what you might be seeing is file system caching. I notice this when performing NFS I/O tests: the first re-read is fast but decays over time as data is rolled out of the cache.

[Dovecot] Looking for IMAP maintenance tools
by Jens Knoell 31 Jan '07

31 Jan '07

Hi I'm currently prowling for some IMAP tools to help me maintain our mailboxes. I'd prefer "pure" IMAP, i.e. no messing with file system directly, but would settle for more crude ways if need be. Specifically I am looking for: - Expunge tool: Outlook does not seem to auto-expunge messages in any way shape or form. So I'd like to run a daily cron to expunge all mailboxes. - Quota helper: Some way to send a warning email once a day or so, saying "you're close to your quota limit, please delete some mail" or somesuch Granted, I could write these two from scratch - but why reinvent the wheel? Thanks Jen

[Dovecot] Dovecot 1.0 on a Mandriva 2007 box
by hackhound 31 Jan '07

31 Jan '07

I installed the RPM, and fought with it for days before realizing the packaged config file is incorrect. So I downloaded the latest tarball and used the sample dovecot.conf file. I was finally able to get dovecot to run as long as I leave the mail_location line commented out. If I uncomment the line dovecot complains that "mail_location" is an "unknown setting". What am I missing? Thanks, JB

[Dovecot] help a journalist: What do you wish the CIO understood about fighting spam?
by Esther Schindler 30 Jan '07

30 Jan '07

Hi, folks. I'm senior online editor at CIO.com, and I'm working on an article for which I'd very much like your help. There's often a lack of communication between techies and top company management. Maybe they don't want to hear about problems; perhaps you give them technical details that are far more granular than they want to know. But dealing with spam is a topic that every e-mail admin has to cope with -- and I'm not sure that the CIO knows the real issues. I have the ear of the boss, however. Essentially, I'm trying to put together the collected wisdom of e-mail and network admins in a fashion that CIOs will understand. Or at least one teeny corner of it. So I have a very simple question to pose to you: ***If you could get your CIO (or top management) to understand one thing, just ONE thing, about fighting spam, what would it be?*** And the follow-up: why did you pick that one item? Feel free to share anecdotes, horror stories, even success stories. While I hope that every CIO will read this article, I also hope that it becomes the document you bring to a new manager ("Here: this is what's important to me"). I'm sure there are plenty of other things that you wish your CIO grokked, whether about e-mail administration or other topics (not the least of which is "the e-mail admin is underpaid"). But I do have to limit myself somehow, and "what's important about fighting spam" has a lot of leeway. I'll be sure to stop by here (as I expect others want to participate in the conversation), but feel free to cc me with your response or send me a private message. I'm hoping for a rather fast turnaround on this article, so please blurt out your first thoughts rather than plan on writing a nice, leisurely response. If all goes well, I'd like to get this article posted in the next couple of weeks. Please be sure to let me know how to refer to you in the article; the usual format is &name, &title, &company and &location ("Esther Schindler is a senior developer at the Groovy Corporation in Scottsdale Arizona"). If you give me some kind of context I'm willing to work without one. That is, I do need some identifying characteristics to give the article credibility ("Esther works at a large finance company in the Southwest").
