I'm about to start building a system for ~10,000 users, using dovecot, and was going to use dspam with it... Is this plugin ready for that kind of use? I'll have a global sieve running, cause users won't be able to have their own sieves. Thanks Tim -- Linux Counter user #273956

Sorry, sent my message (below) to the wrong guy. Dovecot-lda does a pretty good job of implementing the code to support sieve filters. My note was a testimonial to that fact. Just follow the Dovecot wiki instructions.

[Dovecot] LDA Plugin Maybe?
by Timothy White 19 Apr '06

19 Apr '06

I was just looking into setting up DSPAM, with the Dovecot LDA. Essentially, what I was probably going to do, was use DSPAM as the Delivery agent, after postfix, and then have it pass it off to dovecot, or something along those lines. I just had an idea, if we start using libdspam, in the dspam plugin, or one of the other suggested methods, we could have a similar plugin in the LDA, so that if it's marked as spam, deliver it straight into the Spam folder! Also, with Sieve, can we make it create a folder if the folder doesn't exist, and can it modify the subscriptions file? Thanks Tim -- Linux Counter user #273956

[Dovecot] POP3 login error, permissions problem?
by Marc-André Appel 18 Apr '06

18 Apr '06

Hello everybody! I was searching around for an solution of my problem what surely is just a little thing, but nothing helped me out. Here the error in the mail.log: pop3(contact(a)maddy.cc): Failed to create storage with data: /var/vmail/maddy.cc/contact/ pop3-login: Login: contact(a)maddy.cc [84.4.228.150] dovecot: child 30083 (pop3) returned error 89 Who has to be the owner/group for /var/vmail/maddy.cc and /contact ? Because i have the user 'virtual' who manages the maildirs and the accounts (via PostgreSQL) and the user dovecot, but i tried already different scenarios with both and still no success. Do you still have some hints what i do wrong? Have you an idea what is happen here? Thank you very much -- Marc-André Appel 1, Caball d'en Boux F-66740 Villelongue dels Monts France +33.(0)6.86.82.41.31

[Dovecot] unofficial Survey about your Dovecot server :) to compare with my own server setup...
by Flavio Domingos 18 Apr '06

18 Apr '06

Hi Borthers/Sisters Thanks for all the developer(s) and for all the hard work spent on build this great piece of software! I loved Dovecot since it is really easy to set up and really fast but I am really new to it (only 2 weeks and half). Right now, our server configuration is: Server: Apple Xserve G5 dual RAM: 4GB Number of Users: ~ 150 IMAP only users Authentication: LDAP Mailboxes sizes: ~200GB Dovecot version: 1.0 Beta 5 (I am looking forward to beta 7 that was released today) Email client software: mostly Thunderbird 1.5 Right now, we are experiencing occasional problem with imap users unable to connect to the server. With beta 3, we had to restart the dovecot/imap processes almost every 3 hours. with Dovecot beta5 we still have to restart the processes but it seems to occur every 3 days (Friday and Yesterday) and only in a peak time (around 3pm). I am waiting to occur it again and I will be able to grab more information about the number of processes, users, virtual memory, etc, etc. So, at this point, I don't have much information to debug the problem. Let's wait. I guess we have here a nice machine (xserve) and not a huge number of users (~150). So, I would expect that our server would handle the load. But having to restart Dovecot once a while, as I described, is not an option (users are getting frustrated). :( Maybe with Beta 7 with the feature "Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is" can stop our nightmares :) By the way, our dovecot.conf is basically the default sent with the software. We haven't changed much there! Meanwhile, I'd like to know, if possible, whar are you using to run Dovecot like hardware, OS version, number of users and problems that you are experiencing. I'd like to compare with my setup and if it is the case, migrate to pure Linux or FreeBSD if it is more stable than OS/X! Best Regards, Flavio Domingos - San Francisco/CA -

[Dovecot] 1.0.beta6 released
by Timo Sirainen 14 Apr '06

14 Apr '06

Fixes, mostly: * The login and master usernames were reversed when using master_user_separator (now the order is UW-IMAP compatible). * Killing dovecot master process now kills all IMAP and POP3 processes also. + -a parameter to dovecot prints now all settings that Dovecot uses. -n prints all settings that are different from defaults. + Added pop3_lock_session setting + %M modifier returns string's MD5 sum. Patch by Ben Winslow - PLAIN SASL authentication wasn't working properly, causing failed logins with some clients (broken in beta4) - Fixes to Maildir++ quota, should actually work now - Don't crash if passwd-file has entries without passwords (eg. deny=yes databases) - Fixed prefetch userdb to work nicely with other userdbs - If master process runs out of file descriptors, don't go to infinite loop (unlikely to have happened unless the OS's default fd limit was too low) - Fixed non-plaintext password lookups from LDAP. Patch by Lior Okman - %U modifier was actually lowercasing the string. Patch by Ben Winslow

Dear List, is it possible to integrate a function for timelimits the pop3-connects? I require this function for an email-masshosting-project. My problem is, the most customers will lookup all 30 seconds or 1 minutes for new mails, that is stupid so I mean. My idea is a function where the customer must wait (for example) 3 minutes for a pop3-connect and lookup for new emails. Is it possible?

[Dovecot] Compile issues dovecot-1.0.beta7
by Mark E. Mallett 14 Apr '06

14 Apr '06

Hi, I haven't tried compiling 1.0 series since -test52, figured I'd give it a shot. There were a couple of minor problems. This is building on a fairly ancient BSD/OS box, so the issues may not be universal, but I suspect these ones are. ==================== Building in src/lib-dict/dict.c : loading the 'dict' program fails because it can't find various RAND and other functions. Adding -lcrypto fixes. I did this by hand rather than adjusting the configure script; looks like the need for -lcrypto is detected in other cases, but not here. ==================== In src/plugins/quota/quota-fs.c , line 276: #ifdef HAVE_QUOTACTL if (quotactl(QCMD(Q_GETQUOTA, USRQUOTA), root->mount->device_path, root->uid, (void *)&dqblk) < 0) { I believe the first two arguments are backwards, i.e., should be: if (quotactl(root->mount->device_path, QCMD(Q_GETQUOTA, USRQUOTA), root->uid, (void *)&dqblk) < 0) { I have a vague recollection of seeing this already being reported, but can't instantly find it, so what the hey. ==================== Yours, -mm-

[Dovecot] 1.0.beta7

Sorry, the authentication problem still wasn't actually fixed in beta6. Now, this time I tested every possible authentication case that it really works. I'll soon create a CVS branch which is going to stabilize into the 1.0 release. I won't add new features there so it shouldn't really get broken anymore, at least because of new features.. So, two changes in this release: + Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is. - Master login fixes, PLAIN authentication was still broken..

[Dovecot] problem with out-of-box fedora rpm
by Marc Newman 13 Apr '06

13 Apr '06

Hi Folks, Most of the available howtos suggest that an out of the box binary rpm should at least be able to start on a similarly out of the box Fedora Core 4 installation. However, whenever I run /sbin/service dovecot start I get a failed message. Dovecot was installed using the standard package that ships with FC4 (i386 0.99.14). The only slightly anomalous feature of my system is that wlan0 not eth0 is the primary network interface. This hasn't upset anything else though. I even tried disabling the firewall briefly to see if that had any effect, and it doesn't. So, two questions. Firstly, any ideas on why it might be failing to start? Secondly, where might I look (like, which logs/where) for clues? /var/log/messages doesn't contain any references to dovecot (I grepped it), so I'm out of ideas. My sendmail configuration is working perfectly, and I can send and receive emails fine. But I need pop3 access for some of my users. Just to recap, I haven't even got to the point of testing whether its listening, or configuring authentication. It will not start out of the box. Am I missing some essential configuration step? Marc.

[Dovecot] dspam plugin
by Ryan Kolak 13 Apr '06

13 Apr '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey everyone.. been struggling with building a mailserver and i'm almost done. One of the last pieces is integrating dovecot with dspam so that I'm users can train their spam filters easily (sieve filtering is the last piece left.. that should be interesting.. lol) Anyway, I think i found an issue with memory allocation, and I'm not sure if its due to changes to the code base or if its a 64 bit memory issue. When i try to move a message into or out of the spam folder, it fails, and with debugging on, there are strange entries in the syslog. Added a few more debugging statements, and I get the following showing up: Apr 11 00:04:41 uberserver imap: found signature 443b336a271581061887518 Apr 11 00:04:41 uberserver imap: working with signature (<E4>Z Apr 11 00:04:41 uberserver imap: in call dspam Apr 11 00:04:41 uberserver imap: /usr/bin/dspam --source=error --stdout - --class=spam --signature=(<E4>Z Apr 11 00:04:41 uberserver dspam[1361]: Unable to determine the destination user Apr 11 00:04:41 uberserver dspam[1361]: DSPAM agent misconfigured: aborting The line with the correct signature showing up is simply outputing 'signature' after: signature = mail_get_first_header(mail, SIGHEADERLINE); The 'working with signature' that shows the corrupted signature is right before call_dspam is called, and it outputs siglist->sig: ... syslog(LOG_INFO, "working with signature %s ", siglist->sig ); if ((*enh_error = call_dspam (siglist->sig, is_spam))) { ... This leads me to believe that there's a problem with: list_append(listpool, &siglist)->sig = p_strdup(listpool, signature); but I'm really not sure how dovecot deals with allocating pooled memory, as that's what it appears to be doing. I'm not sure what information might be useful to anyone in helping me look into this and the searches i've been able to do have been unsuccessful.
