[Dovecot] Compressed mbox - patch
by kjonca＠o2.pl 14 Apr '12

14 Apr '12

Some time ago I complained about very slow access to compressed mboxes. Unfortunately it looks like that it is very little interest in it, so I have to investigate some things by myself. Firstly: some rationale. Why do I prefer use mbox/maildir over mdbox. Short answer "bus factor" for support mdbox (not only dovecot) Longer answer: if something goes wrong withm maildir/mbox i can use other tools (mutt, or formail or even text editor) and with mdbox ... I am not ISP, I use dovecot as a "gateway" to my (rather huge) mail archive. Most of these mails are rather valuable for me, so I prefer use something "well-known-and-tested". (I can't do like most ISP's do: write in "Terms of Service" that mail can be lost or damaged and we give no warranty :) ) So then: Below my patch. It contains 2 changes: 1. when buffer is compressed, we try to save last marked offset. 2. Increase temporary buffer for decompression. without these changes 1.5 GB of bzip compressed mbox with ~20K messages can't be open in 1.5 day After applying 1. change it can be open in ~1.5 h With both changes it was a few minutes. Maybe it is a good idea to add config parameter to specify size of decompress buffer? Patch is against v2.0.18 -- Gdyby ktoś miał zbędny Toshiba G450 - to chętnie przejmę ;) < asuffield> a workstation is anything you can stick on somebodies desk and con them into using -- in #debian-devel

Just grabbed Dovecot 2.1.2 (which is all properly set up - so I couldn't do anything wrong ;-) and compiled it. Compilation works. Great! The binaries find all their libraries. But two libraries are not quite okay. They don't find their SSL libs: libdovecot-lda.so libdovecot-storage.so Since libdovecot-lda.so doesn't contain the words libssl or libcrypto, I guess that ldd just complains because it uses libdovecot-storage.so. Thus, libdovecot-storage.so is the (only) one left with an incomplete library search path. Luckily, all binaries use some additional libraries which come with a proper library path. So the whole things works, but it's more like some kind of magic. It would be great if libdovecot-storage.so could be fixed as well to make things finally perfect. Thanks for all your effort. (I know this isn't top priority as most people use precompiled stuff and never run into such kind of things.) Greetings, Andreas

[Dovecot] [OT] Outlook identities
by Michael Orlitzky 14 Apr '12

14 Apr '12

Nothing to do with Dovecot, but I figured this is the best place to ask. Do any of the newer versions of Outlook have proper identities support like Thunderbird, mutt, Roundcube, i.e. every other mail client on Earth? We have customers who set up ten different mailboxes for one person because otherwise Outlook won't Do the Right Thing. Is there some way to make it behave like the others? * When sending new mail, you can choose which address to use. * When replying to mail, it sends from the address that the message was sent to by default. * All mail winds up in one inbox. Outlook (2003, 2007) does do this if you set up different mail accounts, but we shouldn't have to do that.

[Dovecot] Unseen messages question
by Antoine Nguyen 14 Apr '12

14 Apr '12

Hi list, this question is related to the IMAP protocol itself, not really to Dovecot. I'm trying to understand what is the more efficient way to maintain the number of unseen messages of the currently selected mailbox. RFC3501 says a client must not issue a STATUS command to the selected mailbox and that information sent by a SELECT is enough. My current idea follows these steps : * Issue a STATUS before the mailbox is selected => I know how many unseen messages it contains * SELECT the mailbox => I got the eventual first unseen message in this mailbox but I don't understand how this info can be useful * Maintain the unseen counter (on client side) according to what the user do * Send a NOOP command every X minutes and look at the RECENT response to see if there are new messages I think it works pretty well when the mailbox is opened only once. Let's imagine this mailbox is opened twice, by different clients. If one client marks a message as \Seen, how can the second client know about this change? Thanks for your help, Antoine Nguyen http://modoboa.org/

[Dovecot] How do I test if the anti spam plugin is working?
by Dr Josef Karthauser 14 Apr '12

14 Apr '12

I've configured the dspam anti spam plugin, but it doesn't appear to be doing anything when I move mail between mailboxes. Can anyone help me determine what's going on? The plugin appears to be loading; at least if I don't define all the required configuration options I get a complaint in the log file. But beyond that I don't see any activity. Here's the config: babel# dovecot --version 2.1.3 The dovecot anti spam plugin config is: protocol imap { mail_plugins = $mail_plugins antispam } and plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash_pattern_ignorecase = trash;Deleted * antispam_spam_pattern = SPAM antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --deliver=;--user;%n@_%d } I don't even appear to be seeing any log entries from the plugin. I've moving an email from my main mailbox into a mailbox called 'SPAM', which is how I thought that it was supposed to be triggered. Cheers, Joe

[Dovecot] Problems with Apple Mail and attachments
by Helga Mayer 12 Apr '12

12 Apr '12

Hello, has anyone experiences with the Apple mail client, to be precise : Mail 5.2? When I copy a message with an attachment from the inbox to a different folder using 'move' or 'copy' , Apple Mail does not properly display the attachment in the new folder. When I copy the same message using 'archive' the attachment shows up properly. There is no difference on the server side. We are using maildirs. The raw messages in the various folders are identical. Deleting plist on the Mac didn't help. After removing and recreation of the account (client side) the attachments are displayed correctly again. Is this an apple problem or has it got anything to do with dovecot.index.cache ? Kind Regards Helga Mayer

[Dovecot] vacation plugins for squirrelmail
by Daminto Lie 12 Apr '12

12 Apr '12

Hi, I am afraid I have a question to ask of you all. I have just completed setting up a mail server running on Ubuntu Server 10.04. It has postfix, dovecot 1.2.19, LDAP and squirrelmail as the webmail. I have also created virtual users accounts on the system through LDAP. I can send and receive mails which is great. Now, what I am trying to do is to set up a vacation auto-reply on the squirrelmail so that users who are about to go on vacation can set it up themselves. I was looking around for the vacation plugins for dovecot that I can incorporate it into squirrelmail. Any help would be very much appreciated. Thank you
