[Dovecot] Getting quotas from an NFS-mounted filestore
by Mike Brudenell 16 Jul '07

16 Jul '07

Greetings - I was just wondering what the state of play was with regard to reading filestore-based quotas when the mailstore is NFS-mounted? Timo mentioned a little while ago that he'd be including it: http://www.dovecot.org/list/dovecot/2007-May/022594.html However it isn't in 1.0.1 and isn't mentioned in the release notes for 1.0.2. Is it going to be a 1.1 feature or will it appear before then? I'm asking because although I can't get the rquota-rquotad patch to build on Solaris I have found some code on the net which does do RPC based quota lookups. I'm toying with the idea of trying to modify rquota-rquotad to use this other code. However this is out of my area of knowledge so it will be an uphill battle ... so if reading quotas from NFS-mounted filestores will be coming Real Soon Now I'll probably just wait instead. So any ideas as to timescales, please?

[Dovecot] quota warning - take 2
by Nicolas Boullis 16 Jul '07

16 Jul '07

Hi, About one month ago, I sent a patch to this list to implement warnings when a user is close to reach his quota. I tried to follow Timo's advice to improve my code, and here (at last) is a new patch. Things I did not fix: - This patch is still for dovecot 1.0, as I will need warnings with dovecot 1.0. I may rewrite it for CVS HEAD in the future but can't promise. - I'm still using system() rather than fork()+exec()+waitpid() since I don't know a good time to run waitpid(). Comments are welcome. Timo, will you consider to add this to your unofficial patches? Cheers, Nicolas Boullis

[Dovecot] v1.0.2 released
by Timo Sirainen 15 Jul '07

15 Jul '07

http://dovecot.org/releases/dovecot-1.0.2.tar.gz http://dovecot.org/releases/dovecot-1.0.2.tar.gz.sig Fixes several bugs. This release also adds compatibility with upcoming Dovecot v1.1 so it'll be possible to upgrade to v1.1 and back to v1.0.2 without anything breaking. * dbox isn't built anymore by default. It will be redesigned so it shouldn't be used. + Maildir: Support reading dovecot-uidlist (v3) files created by Dovecot v1.1. - Maildir: "UIDVALIDITY changed" errors could happen with newly created mailboxes - If "INBOX." namespace was used, LIST returned it with \HasNoChildren which caused some clients not to show any other mailboxes. - Maildir++ quota: If multiple processes were updating maildirsize at the same time, we failed with "Unknown error". - IMAP: IDLE didn't actually disconnect client after 30 minutes of inactivity. - LDAP passdb/userdb was leaking memory - deliver: %variables in plugin {} weren't expanded - deliver: Don't bounce the mail if Sieve plugin returns failure

[Dovecot] How to stop POP clients from downloading mail after directory corruption
by Frank Church 15 Jul '07

15 Jul '07

Transferring my email from a Courier server, as well as some corruption in my dovecot installation caused all POP mails to be downloaded again. I surmised that the dovecot-uidlist file was not present in the first instance, and was probably out of sync in the second. Is there a way to do some reindexing and uid-list regeneration that can stop the problem from occurring? - Frank

[Dovecot] More Descriptive Logging Needed
by Joseph D. Wagner 15 Jul '07

15 Jul '07

(Everything herein refers to dovecot-1.0.1.) I'm sorry to say that I've been having troubles with dovecot. While attempting to troubleshoot them, I've found the existing logs to be lacking. In particular, I've had a lot of difficulty with the client<->server connection disconnecting, but the only message I get in the logs is "Disconnected". After dissecting the code a bit, I've found quite a number of places where the code will close the connection logging nothing more than the word "Disconnected", or worse, it will not specify a reason in which case the code in client_destroy() will log the default "Disconnected". Because of this, isolating the offending code has been a bit difficult. (I realize the problem may lie with the client, but I cannot even begin to program a work around until I isolate the exact place and cause of failure.) In an attempt to change the logging to be more descriptive myself, I already changed src/imap/cmd-fetch.c:85 on my own copy of dovecot from: client_disconnect(cmd->client, "Disconnected"); to: client_disconnect(cmd->client, "Disconnected in FETCH"); This makes the logging both more descriptive and more in line with other parts of code, like src/imap/cmd-append.c:50 which already say: client_destroy(client, "Disconnected in APPEND"); As luck would have it, my problem was not in the FETCH command. I'm now looking at the client_read() function in src/imap-login/client.c:318-334. If I'm reading the code right, then "i_stream_read(client->input)" returning "-1" means that the socket/stream is already disconnected, right? In other words, some function attempted to read off of a socket/stream that was already closed, right? If so, shouldn't the client_read() function not have been called in the first place? Please let me know if I'm wrong. I've been banging my head against the wall trying to make sense of all the different code. Any assistance you can offer would be appreciated. Joseph D. Wagner

[Dovecot] problem with subscriptions file version 1.0.1
by Liz 13 Jul '07

13 Jul '07

Hello, I am currently working on a patch to add IMAPdir support to dovecot. (For those who do not know, IMAPdir is exactly like Maildir except that instead of having a folder .foo it would just be foo. The advantage is that the file system is slightly easier to search through without the dot in front of the folders.) The first thing I did was get the configuration file working for Maildir. So I know that the problem has nothing to do with the configuration file. Next I looked through the actual source code to find any place where a dot might be added to the beginning of a folder. It transpired that there is a constant, MAILDIR_FS_SEP_S, which is assigned the value ".". I deleted all the occurrences of this constant, compiled the source code again, and ran into a rather interesting problem. When I try to create a new folder through Thunderbird on a separate machine, the folder is not visible unless I restart Thunderbird. I checked on the machine acting as a server and the folder is created and the subscriptions file is updated, and the dot at the beginning is indeed absent. So I see no reason why this should not work. If I had deleted some of the constants that ought not have been deleted, the subscriptions file would not be readable at all and I would not be able to see the folder when Thunderbird restarts. If there were some sort of deadlock going on with the subscriptions file, one would think that it would not be caused by deleting the constants. I would have run into the problem before editing any of the source code. I know for fact that the only thing different about my source code and the code available for downloading is the deleted constants. If anyone has any ideas, please let me know. If you need more information, please feel free to prompt me for it because I have no idea what might be useful that I have not already provided. Regards, Elizabeth Bermel

[Dovecot] telnet to dovecot not creating mbox
by Andy Fadich 13 Jul '07

13 Jul '07

Hi, Whenever I create a new email user, telnet fails until an email is sent to that user to create his mbox. This is the error that it gives. Anyone know how to fix this? I could create the email account script to touch the users mbox, but I havn't needed to do this in the past with ipop3d and dovecot on a different server. [root@mail log]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user testact +OK pass +OK Logged in. -ERR Internal error occurred.
