[Dovecot] Quota Warning problems
by Anatoly Bashmakov 27 Feb '08

27 Feb '08

Hello, list! Seems that quota warning feature doesn't work for me. I have dovecot-1.0.9 with quota-rewrite patch (http://dovecot.org/patches/1.0/quota-rewrite-1.0.9.diff) Dovecot works as imap, pop3 server and lda for postfix. Here is plugin section in dovecot.conf >>>/etc/dovecot.conf<<< ... plugin { quota = maildir quota_rule = *:storage=10M quota_warning = storage=50%% /usr/local/bin/quota-warning.sh 50 quota_warning2 = storage=20%% /usr/local/bin/quota-warning.sh 80 } >>>cut<<< >>> /usr/local/bin/quota-warning.sh <<< #!/bin/sh echo "Test" > /tmp/script.txt >>>cut<<< >>>shell<<< # /usr/local/dovecot-1.0.9/sbin/dovecot -c /usr/local/dovecot-1.0.9/etc/dovecot.conf ILoading modules from directory: /usr/local/dovecot-1.0.9/lib/dovecot/imap IModule loaded: /usr/local/dovecot-1.0.9/lib/dovecot/imap/lib10_quota_plugin.so IModule loaded: /usr/local/dovecot-1.0.9/lib/dovecot/imap/lib11_imap_quota_plugin.so IEffective uid=65534, gid=65534, home= IQuota root: name= backend=maildir args= IQuota rule: root= mailbox= bytes=10485760 messages=0 IQuota warning: bytes=5242880 messages=0 command=/usr/local/bin/quota-warning.sh 50 IQuota warning: bytes=2097152 messages=0 command=/usr/local/bin/quota-warning.sh 80 >>>cut<<< But when user accept 8MB size mail script doesn't execute.

Thank you. P.S. Sorry for my English. P.P.S. Quota rules work perfectly. -- Best regards, Anatoly Bashmakov

[Dovecot] multiple ip and ssl
by Lampa 27 Feb '08

27 Feb '08

Hello, is possible in some way use on each ip address different certificate (for imap, for pop3). There are options like (but that is not enough for me): protocol imap { listen = *:10143 ssl_listen = *:10943 .. } protocol pop3 { listen = *:10100 .. } I have server for 4 domains (each has own ip address), so i need bind one ip address to one domain to one certificate(each certificate contains name of domain): domain1.tld (x.x.x.100) -> certificate domain1.tld.pem domain2.tld (x.x.x.101) -> certificate domain2.tld.pem domain3.tld (x.x.x.102) -> certificate domain3.tld.pem domain4.tld (x.x.x.103) -> certificate domain4.tld.pem Or i must run different instances of dovecot ? (using other config) ? Thank you for advices. -- Lampa

[Dovecot] Dovecot 1.0.10 <- IMAP -> Nokia N95 ?
by Patrick 27 Feb '08

27 Feb '08

Hi, I was wondering if anyone has IMAP working between Dovecot 1.0.10 and a Nokia N95 (8GB version with firmware 15.x.x.x)? I've been trying to make it work using a default Dovecot config but the N95 just hangs when updating the folder list which has a bunch of nested folders. So I made a new test user and started from there. That works but the moment I add a folder in Evolution and a subfolder in that one then the N95 seems to fall apart. In wireshark all I see are a bunch of TCP transmissions over and over from the Dovecot server to the N95 and the N95 just sits there. I also configured Dovecot with a basic private namespace but that did not make any difference: namespace private { separator = / prefix = location = maildir:/var/spool/mail/%u/ inbox = yes } Any tips much appreciated. Thanks and regards, Patrick

[Dovecot] Multiple password schemes
by Jan van den Berg 26 Feb '08

26 Feb '08

Hi, right now I have default_pass_scheme = MD5-CRYPT in my dovecot-sql-auth.conf file. This works; however I noticed because of history a lot of my users still have a CRYPT password (not a MD5-CRYPT password). Now I get these errors: dovecot: Feb 26 13:08:17 Info: auth-worker(default): sql(***, *******): MD5-CRYPT(0lifant) != 'i3/S6ZswGSfbk' Any way to make Dovecot use another (fallback) password scheme when the default scheme isn't working? Cheers, Jan

[Dovecot] dovecot 1.0 + postfix quota warning
by Vusi 26 Feb '08

26 Feb '08

Hello, I need to know how to make a quota warning message from Dovecot or Postfix. I'm using Dovecot 1.0.rc15 and Postfix 2.3.3. I didn't installed the quota-warning patch cause i read that it doesn't work with dovecot filesystem quotas (as i'm using). What else can i use for this? I wanna warn users when they reach ..let's say 90% of their quota by sending an e-mail to their address. I'm using maildir format. Thanks, Radu ____________________________________________________________________________________ Never miss a thing. Make Yahoo your home page. http://www.yahoo.com/r/hs

[Dovecot] Crash on malformed ldap user_filter
by Anders 26 Feb '08

26 Feb '08

I did a little too much copy/paste, and ended up with an ldap config file containing a line of the form user_filter = user_filter = (&objectClass=... (with "user_filter =" repeated). This caused the auth process to segfault (v1.1.rc1). I suppose that I can reproduce this problem if more information is needed. Anders. 11:56:33 localhost dovecot: auth(default): ldap(a(a)invalid,127.0.0.1): user search: base=o=hosting,dc=invalid, dc=dk scope=subtree filter=user_filter = (&(objectClass=JammMailAccount)(mail=a@invalid)(accountActive=TRUE)(delete=FALSE)) fields=mail 11:56:33 localhost dovecot: child 21296 (auth) killed with signal 11 11:56:33 localhost dovecot: pop3-login: Internal login failure: user=<a@invalid>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured (addresses are edited)

[Dovecot] Redundant timers
by Anders 25 Feb '08

25 Feb '08

Hello. I am on an irrational crusade against unneeded timers (it started as a well-meaining power saving exercise), and I have now started removing polling in Dovecot. Attached is a patch with the work I did on this the other night. Would something like that be acceptable, or should I make it in a different way? There seems to be no one-shot timer support, right? Is there a Dovecot coding style document? (I did notice that there appears to be an 80 char width that I exceeded) Cheers, Anders
