[Dovecot] disabling pop/imap per mail address?
by Armijn Hemel 24 Apr '07

24 Apr '07

hello, first of all I want to say thanks to Timo for Dovecot 1.0. We've been running it in production at the company where I work and we're very pleased with it. Good job! One thing that we were wondering about today is if we can disable a certain protocol depending on the mailbox. So for example: user A can access via pop3s and imap, user B can only access via pop3, user C can use only imaps, and so on. thanks! armijn PS: am I assuming correctly that IMAP namespaces will make it possible to have shared IMAP folders with Dovecot? I'm still a bit of an IMAP dummy -- --------------------------------------------------------------------------- armijn(a)uulug.nl | http://www.uulug.nl/ | UULug: Utrecht Linux Users Group ---------------------------------------------------------------------------

[Dovecot] Experience with Dovecot + Sieve + Webmail?
by Steffen Kaiser 24 Apr '07

24 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, there were some posts into this lists regarding Webmail interfaces and Sieve. What are the experiences with them? I need a webmail frontend that is capable of IMAP, supporting dovecot's namespaces, verifying PGP and managing Sieve in conjunction with Dovecot. I found two mature products, I also saw posts about, so I'm going to ask. Some posts on this list suggest that some are using SquirrelMail/avelsieve and some Horde (IMP/Ingo). What are the experiences with them? Are they stable and are there configuration glitches (there is a thread about a bug in avelsieve, for instance). How do they interact with Dovecot in order to find the user's homedirectory to get/put the Sieve script? Maybe it's offtopic for the Wiki, but would you mind share your configuration on the Dovecot Wiki?

[Dovecot] message-of-the-day feature?
by Steven F Siirila 24 Apr '07

24 Apr '07

For lack of a better name, we are interested in a feature where one could get a notice out to all Dovecot users as quickly as possible, possibly without going through an MTA even. Given a message and a list of userids we could certainly do a mailing on the MDA server itself going through both Postfix and Dovecot LDA. However, we were wondering what other options we might have in Dovecot. For example, would it be possible to place the message into some file which Dovecot periodically checks for, and if the file exists, either present it to the user as a new message, or automatically deliver it at that time via Dovecot LDA? -- Steven F.

[Dovecot] Auth MD5 problem

Hi, I am using dovecot 1.0 with squirrelmail. But when i use $imap_auth_mech = 'digest-md5' instead of plain, dovecot throws this line: dovecot: Apr 23 09:16:07 Info: imap-login: Aborted login: user=<azher>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, secured and user can't login.

[Dovecot] SASL Problems
by Phillip T. George 23 Apr '07

23 Apr '07

Hello all, I seem to be having a problem with SASL. It doesn't seem to work with Outlook. Upon searching a bit, I found that I need to enable "login" for auth mechanisms. However, when I do that, (after I stop and start dovecot and postfix), and then try to use SMTP auth using Outlook, it causes postfix to crash. It works fine with Thunderbird still though. Any ideas as to what the cause might be? I'm using Dovecot 1.0.0 and Postfix 2.3.5. Thanks, Phillip

Re: [Dovecot] Mixing MBOX and Maildir?

> Is it possible to have some folders be mbox and some be maildir format? Claudio Succa posted his successful configuration back in 2005, at my request. I never actually put it into practice, and I don't know how much has changed since 1.0test68, but good luck!: http://www.dovecot.org/list/dovecot/2005-June/007574.html

[Dovecot] Trying to explain mutt+dovecot(ssl) to myself :(
by Wilkinson, Alex 23 Apr '07

23 Apr '07

Hi all, I have recently migrated my mail from courier-imap to dovecot. In doing so, I finally configured mutt to connect to imaps (SSL). In the end I got it all working. I then sat back and thought: "I kinda don't understand the SSL/TLS part even though it works". And I hate setting stuff up and not truely understanding the mechanics of it. So I started to write about it and am stuck. Can those that _understand_ mutt+ssl have a read of what I wrote to myself and give me your $00.02 worth (corrections etc). Trying to explain mutt+ssl and getting it all wrong --------------------------------------------------- * mutt(with openssl support built in) initiates with a "SSL-Client-Hello" to SSL on port 993 i.e. mutt's capabilities (algorithms, SSL version etc). * dovecot:993 compares mutt's CipherSuites with its own. Of the CipherSuites mutt and dovecot have in common, dovecot:993 chooses the _most_ secure algorithm. * Dovecot:993 will then tell mutt what it has decided to use and assigns a Unique session ID. From now on all communication is via this ID. * Now that the CipherSuite is set between mutt and dovecot, dovecot sends its SSL certificate to mutt [/usr/local/share/dovecot/certs/dovecot.pem]. mutt then uses dovecot's corresponding public key [/usr/local/share/dovecot/private/dovecot.pem] to verify that the ceritificate is authentic. * once mutt has verified that the certificate is authentic ... and here I got unstuck.

[Dovecot] deliver failing to execute sendmail (sieve)
by Justin McAleer 21 Apr '07

21 Apr '07

I have apparently done something to mess up my test installation, as deliver's attempts to send messages now fail with the following error: deliver(user(a)example.com): execv() failed: No such file or directory In these cases, I have sieve rules trying to send messages. It had been working though, and I've tried going through all the changes I made yesterday (related to dictionary quota debugging) to find what could be wrong, but no luck so far. So, I was hoping for suggestions. Basically, deliver seems to not know where sendmail is. I have sendmail_path set in dovecot.conf (never changed that), yet when deliver tries to pull the location via deliver_set->sendmail_path, it's just returning an empty string. If I hard-code the location in smtp-client.c, it works again. Any ideas?
