I'm sitting here working away on various unrelated projects and watching patch after patch after patch flow in from Timo to fix all sorts of problems people are reporting. A coding madman on fire. Thanks Timo, you rock. I appreciate the time you spend on this software, I'm sure everyone else does as well. :) -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Some question about "auth default", "auth default_with_listener" and others
by Vitalij Satanivskij 06 Mar '07

06 Mar '07

Hello, Trying to set in dovecot.conf more than one auth section found that imap and pop3 auth process use bose of them. Loooks like thay do in round-robin way or maybe another way. Example of config: auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = dovecot group = dovecot } } } auth smtp_auth { mechanisms = login plain passdb sql { args = /usr/local/etc/smtp_auth.conf } userdb prefetch { } socket listen { client { user = mailnull # User running Dovecot LDA group = mail # Or alternatively mode 0660 + LDA user in this group path = /var/run/auth-smtp-plain mode = 0660 } } } Main problem - dovecot-mysql.conf and smtp_auth.conf have doferent sql querys inside, and if user try to auth via pop3 service but thru the "auth smtp_auth", than it's failed in any way. Quetion - Is exist any way to limit default doecot auth process to use just "auth default" for authintification ? maybe some options like "services= POP3 IMAP" inside? Or maybe there is anather way to do this ?

To say nothing of having built the whole edifice with the integrity, simplicity and elegance, that these changes are possible. I've long felt that doing programming can give one an awed appreciation for Creation. In principio, in the beginning, it is of the essence to get the first principles right....otherwise, everything that follows is a downhill slide to garbage. Timo is like one of the master cathedral builders of the Renaissance....... Here's a ludicrous example of missing something essential http://www.dailytech.com/Lockheeds+F22+Raptor+Gets+Zapped+by+International+… -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[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] user_global_uid - tricky to set
by Alexej Davidov 06 Mar '07

06 Mar '07

Hola! Dovecot should serve virtual mail users. So I've set user_global_uid and user_global_gid in dovecot_ldap.conf to vmail/vmail. Also I've commented auth the user_attrs field. Still Dovecot tries to switch to the uid that is defined in the LDAP entry. It took me some time to figure out, that the only way to prevent this is to set user_attrs = foo=uid,bar=gid or something like this, so Dovecot doesn't have a chance to find the uid/gid. Still it will perform some LDAP lookups. In my oppinion, Dovecot shouldn't try to get the uid/gid from LDAP if the user_attrs field is undefined. I'm using Dovecot 1.0rc24 on Debian sid. Regards, A.

[Dovecot] mbox_min_index_size panics at index-storage.c:368
by Scott Worley 06 Mar '07

Setting mbox_min_index_size above zero and accessing a small mbox triggers the panic in index_storage_mailbox_init() at dovecot-1.0.rc25/src/lib-storage/index/index-storage.c:368 dovecot: Mar 03 01:28:03 Error: IMAP(user): in-memory index creation failed. dovecot: Mar 03 01:28:03 Error: IMAP(user): Raw backtrace: imap [0x80b52c4] -> imap [0x80b4d59] -> imap(index_storage_mailbox_init+0x35e) [0x808d1ce] -> imap [0x806faec] -> imap [0x806fc99] -> imap [0x806fe98] -> imap(_cmd_select_full+0x83) [0x8059f43] -> imap(cmd_select+0x19) [0x805a139] -> imap [0x805bb85] -> imap [0x805bb0f] -> imap(_client_input+0x7c) [0x805bccc] -> imap(io_loop_handler_run+0x108) [0x80bb648] -> imap(io_loop_run+0x20) [0x80babe0] -> imap(main+0x4ae) [0x8063efe] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb7e46856] -> imap [0x8056991] dovecot: Mar 03 01:28:03 Error: child 2321 (imap) killed with signal 6 The immediate cause seems to be that mail_index_open_files() in dovecot-1.0.rc25/src/lib-index/mail-index.c returns zero at line 1536.

[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?
