[Dovecot] 1.0.rc24 released
by Timo Sirainen 07 Mar '07

07 Mar '07

And more fixes. * Dovecot now fails to load plugins that were compiled for different Dovecot version, unless version_ignore=yes is set. This needs to be explicitly set in plugins, so out-of-tree plugins won't have this check by default. - pop3_lock_session=yes could cause deadlocks, and with maildir the uidlist lock could have been overridden after 2 minutes causing problems - PAM wasted CPU by calling a timeout function 1000x too often - Trash plugin was more or less broken with multiple namespaces and with multiple trash mailboxes

[Dovecot] quota warning
by Nicolas Boullis 06 Mar '07

06 Mar '07

Hi, As suggested by Timo, I have tried to implement some warning when the user gets close to his quota limit. The patch is attached. It is configured in the plugin section of the configuration file: quota_warning = 80:0:/usr/local/bin/quota_warning.sh With this one, /usr/local/bin/quota_warning.sh is executed each time a mail brings the total size from below 80% to 80% or above. The second number serves as a limit for the count. The /usr/local/bin/quota_warning.sh script builds the warning message and delivers it with cat << EOF | /usr/lib/dovecot/deliver -c /etc/dovecot-nowarning.conf where /etc/dovecot-nowarning.conf is the same as my normal configuration file, except that it lacks the quota warning option (that is required in a situation where the warning message is large enough to bring over the 80% limit, to avoid a warning loop). Comments are welcome. Cheers, Nicolas Boullis

[Dovecot] Disconnects with proxies / new facts
by Michael Kress 06 Mar '07

06 Mar '07

Hi, I just tried the below with the current version 1.0 RC15 and I still got the Problem: telnet gives me the following output: -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- +OK dovecot ready.u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r -ERR invalid command u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r _-ERR invalid command _ 1-ERR invalid command 1 -ERR invalid command -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- The above output results from the following entry: user user_1[ENTER] So now I know that this is no version issue. Can you tell me something on how I can find the solution for this problem? I don't think its a firewall issue, I disabled my Desktop Firewall. On the server I use shorewall, but of course, port 110 is open and it works disabling AntiVir on the client side. The error also occurs when I disable the Server Firewall as well. The error is reproducible on several PCs (I tried 3 PCs). Have you got any hint? Without solving the problem, I have to switch the pop3 server to another one, because this problem is really a crucial one.The only problem is: I loke dovecot. :) Thanks in advance! Regards, Michael -------- Original-Nachricht -------- Betreff: [Dovecot] Disconnects with proxies Datum: Wed, 06 Dec 2006 22:43:00 +0100 Von: Michael Kress <kress(a)hal.saar.de> An: dovecot(a)dovecot.org Hi, I know I shouldn't ask stuff like this when using dovecot-0.99.11-4.EL4 (CentOS-4.4), but why I'm asking this is whether it's worth to switch from rpm based upstream dovecot to a self compiled one or not and thus I think you wouldn't kill me presenting you this question. o:-) I've got a problem with dovecot regarding a pop3 proxy issue. When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this: pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42] Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue?

[Dovecot] Replacing qmail + vpopmail with: sendmail + dovecot
by Oliver Schulze L. 06 Mar '07

06 Mar '07

Hi, I wonder if it posible to replace qmail + vpopmail with sendmail + dovecot? The idea is like this: - use sendmail + milter API to filter spam/virus and deliver the email to the dovevot MDA (LDA) - dovecot should save the email to the directory as specified in the vpopmail DB - maintain the vpopmail BD (users + passwd) - use dovecot pop3/imap for the clients - use sendmail again to receive the email from the pop3/imap users and deliver the email to the internet as usual. Anyone has done this? It is posible in the paper, in the real world? many thanks Oliver -- Oliver Schulze L. | Get my e-mail after a captcha in: Asuncion - Paraguay | http://tinymailto.com/oliver

by Rob Klingsten 04 Mar '07

Hello folks -- I'm using Debian etch and I've got Mysql 5.0, Dovecot 1.0rc15 and DSpam 3.6.8... I've downloaded the mysql-dspam-plugin code, and it builds without errors. But when trying to start Dovecot I get: Starting mail server: dovecotIEffective uid=65534, gid=65534 ILoading modules from directory: /usr/lib/dovecot/modules/imap Emodule /usr/lib/dovecot/modules/imap/lib_dspam.so: dlsym(dspam_init) failed: /usr/lib/dovecot/modules/imap/lib_dspam.so: undefined symbol: dspam_init Error: imap dump-capability process returned 89 Any help with how to fix this would be great! I'm not really a programmer so I'm not quite sure where to look... thanks!! Rob Klingsten

[Dovecot] Still issues with new message count...
by Brian Taber 01 Mar '07

01 Mar '07

I am still having issues with new message count. When I move a message to another folder, it counts that message as new until you go into that folder. Is there a way I can solve this? Could it have something to do with NFS? I have tried all the NF workarounds with no luck... I have also tried NFSv3 and NFSv4, no difference. I store the indexes on the local drive...
