[Dovecot] hard link between courierimapuiddb and dovecot-uidlist?
by Jeff Tucker 21 Apr '06

21 Apr '06

Hi, guys. I'm attempting to transition between Courier IMAP and Dovecot. I may not be able to transition all the courierimapuiddb files instantly or even transition all my servers at the same time. Ideally, it wouldn't matter. Users can login and get to a Courier IMAP machine or a Dovecot machine and read their email (all mounted via NFS). My question is: is there any reason I can't just do a hard link between courierimapuiddb and dovecot-uidlist? That way, I can transition users over to Dovecot at my leisure. And, if I need to, I can move back to Courier. The hard link is essentially free and lets me make sure these files stay synced. Thanks Jeff

[Dovecot] Beta 7 maildir++ "unlimited quota"
by Apps Lists 21 Apr '06

21 Apr '06

Hi. It looks like Beta 7 is treating a zero quota in maildirsize as a literal quota value. The maildir++ specification says a zero quota means unlimited. Steve

[Dovecot] UIDL documentation
by Mark E. Mallett 21 Apr '06

21 Apr '06

Hi, I see this in the 1.0-beta7 dovecot-example.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier version 0 : %f # Courier version 1 : %u # Courier version 2 : %v-%u # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u # Older Dovecots : %v.%u # # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. # # NOTE: Nowadays this is required to be set explicitly, since the old # default was bad but it couldn't be changed without breaking existing # installations. %08Xu%08Xv will be the new default, so use it for new # installations. and on the wiki at http://wiki.dovecot.org/Migration there is this: By default Dovecot generates POP3 UIDs differently than UW-IMAP. If you want to preserve them, with 0.99.x you'll have to patch Dovecot. With 1.0-tests you can use: pop3_uidl_format = %08Xv%08Xu In the dovecot-example.conf file, it appears that the mentions of "%08Xu%08Xv" as being fail-safe and being the new default may be typos, since that format doesn't seem to come from anywhere. Should they not say "%08Xv%08Xu" ? (It'll still provide the same sort of unique value, only with the ends reversed; i.e. it should still work ok. But consistency and compatibility is nice.) mm

[Dovecot] unlink a directory

Hi, Occasionally I get an error message in my dovecot log when, in evolution, I click on the inbox: dovecot: Apr 21 00:07:06 Error: imap(admin): unlink(/home/admin/.maildir/cur/1145393825.P23027Q0M159929.terminator.odyssey.nl:2,ST) failed: Is a directory Instead of the message being delivered as a file it appears to be written as a directory. Deleting those directories solves the error message from reappearing. Any ideas? I use FC5, dovecot-1.0-0.beta2.7, postfix-2.2.8-1.2, procmail-3.22-16.2.1 Regards, Alfred

Does this Maildir++ implementation have an "unlimited" quota? It looks like all of the other Maildir++ software uses "0" for this ... it doesn't seem to work on Dovecot. Steve

[Dovecot] Does NIS/yp work for authentication
by Stewart Dean 19 Apr '06

19 Apr '06

If a host is running NIS (passwd file ends in +::0:0:::) authentication, will dovecot be able to authenticate with auth_userdb = passwd directly and automagically or do you have to do a ypcat passwd > pwfile periodically to generate a passwd file that dovecot can use? ?

[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

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?

[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 -
