[Dovecot] dovecot overquota and delete message
by sa 07 Mar '08

07 Mar '08

Hi all, i use dovecot-1.1_rc1 with postfix and maildrop as deliver. The problem is where user gets overquota, at this point he is unable to delete message in pop3 as imap. dovecot.conf has: plugin { quota = maildir } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } I change it to plugin { quota = maildir:ignore=Trash } and plugin { quota = maildir:storage=100240:ignore=Trash } but the problem persist. I have to del manually maildirsize file to get the user back to delete. Any suggestion ? tnx s

[Dovecot] Not using "." as separator?
by Grant Edwards 07 Mar '08

07 Mar '08

When using maildir storage, is there any way to use something besides "." as the folder separator? I like to use folder names that match people's e-mail addresses (that's a default behavior in mutt), and "." is a pretty popular character in e-mail addresses. Ideally, I'd like to use "/". Is "." allowed in mailbox names when using mbox storage? -- Grant Edwards grante Yow! As President I have at to go vacuum my coin visi.com collection!

[Dovecot] Logging Options
by Steffen Ille 07 Mar '08

07 Mar '08

Dear Listmembers, I tried to figure out how to get statistics not only about the amount of mails which where sent from / to my mailusers, but also about the size in byte (e.g. to compare with other traffic stats) for each of my users. postfix shows me the size of sent mails per user, but afaik I cannot get the size of rcvd mails per user with it. I use the dovecot LDA with postfix and in this lda - logfiles I also cannot see a byte-like size of delivered mails. Is there any possibility get such statistics working? My used versions are (all Debian Etch): dovecot: 1.0.10 postfix: 2.4.6 Regards, Steffen Ille

[Dovecot] Wrong message information reported shortly after delivery
by Ron Avriel 07 Mar '08

07 Mar '08

Hi, If an IMAP fetch is issued some "short" time after a message was delivered with dovecot deliver then dovecot reports wrong (zero) values for that new message. Afterward, it reports the information OK. This causes problems to our IMAP client. The problem is easily reproduced with a large message on a slow machine. I'm using dovecot 1.0.10 Here's a sample trace: 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) 1 OK Fetch completed. ######## Here dovecot reports a new message (5) arrived ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 EXISTS * 5 RECENT 1 OK Fetch completed. ######## This is where dovecot reports wrong information about message 5 ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "01-Jan-1970 00:00:00 +0000" RFC822.SIZE 0 UID 5) 1 OK Fetch completed. ######## The same wrong information is repeated ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "01-Jan-1970 00:00:00 +0000" RFC822.SIZE 0 UID 5) 1 OK Fetch completed. ######## The same wrong information is repeated several times ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "01-Jan-1970 00:00:00 +0000" RFC822.SIZE 0 UID 5) 1 OK Fetch completed. ######## Trace truncated here ######## ######## Finally, correct information is reported ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:41:07 +0200" RFC822.SIZE 3378380 UID 5) dovecot -n: # 1.0.10: /etc/dovecot.conf log_timestamp: “%Y-%m-%d %H:%M:%S ” protocols: imap listen: *:143 ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no first_valid_uid: 150 last_valid_uid: 150 dotlock_use_excl: yes fsync_disable: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_plugins: quota imap_quota auth default: mechanisms: plain login user: nobody master_user_separator: * passdb: driver: sql args: /etc/dovecot-sql.conf passdb: driver: passwd-file args: /etc/dovecot.masterusers master: yes userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail plugin: quota: maildir:storage=1024 Thanks, Ron ____________________________________________________________________________________ Never miss a thing.

[Dovecot] Quota exceeded - ignore setting
by Fabian Lazarski 06 Mar '08

06 Mar '08

Hello, I have a problem if I use the 'ignore' setting in my dovecot.conf A delete operation in the client means that the mail is copied to Trash mailbox. If the user is already over quota the delete operation will fail. Therefore I use the ignore setting, which doesn`t count the quota at all for the given mailbox. But it doesn`t work. I got still a quoted exceeded failure in my client. Here is the plugin part of my dovecot.conf (The trash folder was renamed in Papierkorb on the mailserver): plugin { quota = maildir:storage=0:ignore=Papierkorb acl = vfile:/etc/dovecot/acls } and the appropriate View definition: SELECT u.userid, 999 AS uid, 8 AS gid, rel_homedir(v.volume::text, u.userid::text) AS home, ('maildir:storage='::text || u.quota::text) || ':ignore=Papierkorb'::text AS quota FROM mailuser u, user_volume v WHERE u.userid::text = v.userid::text;iate view definition: here is a section of imap-info.log: dovecot: 2008-03-06 18:30:55 Info: auth(default): master in: REQUEST 184 3289 173 dovecot: 2008-03-06 18:30:55 Info: auth(default): sql(dg-SW3,172.27.60.237): SELECT * FROM dovecotuser WHERE userid = 'dg-SW3'; dovecot: 2008-03-06 18:30:55 Info: auth(default): master out: USER 184 dg-SW3 userid=dg-SW3 uid=999 gid=8 home=mail02/dg/SW3 quota=maildir:storage=2097152:ignore=Papierkorb master_user=master dovecot: 2008-03-06 18:30:55 Info: imap-login: Login: user=<dg-SW3>, method=PLAIN, rip=172.27.x.y, lip=172.27.x.x dovecot: 2008-03-06 18:30:55 Info: auth(default): client in: AUTH 174 PLAIN service=IMAP lip=172.27.x.x rip=172.27.x.y resp=<hidden> dovecot: 2008-03-06 18:30:55 Info: auth(default): passwd-file(master,172.27.x.y,master): lookup: user=master file=/etc/dovecot/dovecot-master.pwd dovecot: 2008-03-06 18:30:55 Info: auth(default): passdb(master,172.27.x.y,master): Master user logging in as dg-SW3 dovecot: 2008-03-06 18:30:55 Info: auth(default): client out: OK 174 user=dg-SW3 Used dovecot Version is 1.0.2 Can someone help?

[Dovecot] two problems with dovecot and antispam-plugin and qmail/vpopmail
by Mario Cardia 06 Mar '08

06 Mar '08

Hi! I'm trying do use antispam plug-in to split spams in different folders. My problem is with backends... I tried dspam backend and now I'm tring mail training backend. With dspam backend the problem is: When I receive a mail then dspam creates a data directory to store his data as it should do it. But when a try to move the message to Spam folder I get an error (could not execute dspam). If I remove de data directory, it works... I can move the message and by doing this de data directory is re-created. So I decided to try mail training backend. My configuration is: antispam_mail_tmpdir = /tmp antispam_mail_spam = spam@%d antispam_mail_notspam = nospam@%d antispam_mail_sendmail = /opt/qmail/bin/sendmail # antispam_mail_sendmail_args = -f;%u But an error occurs. (Failed to send mail) I tried to use qmail-inject instead but the same error occurs. Then i tried to use de args commented (-f;%u) but didn't work yet. I also tried to use a complete e-mail address to spam and notspam parameters... but nothing seems to works. So I created a shell script to use instead a sendmail program to be able to debug de error. The script has these contents: #!/bin/sh /opt/qmail/bin/sendmail 2> /tmp/error.txt The result of this test is: qmail-inject: fatal: unable to parse this line: Return-Path: <mario(a)cardia.com.br>Delivered-To: isharedev.travelnet.com.br-mario(a)isharedev.travelnet.com.br Note that there is not a "\n" between return-path and delivered-to Can someone help me? (Sorry by my english, I'm brazilian) Tks Mário Cardia

[Dovecot] Can't connect to auth server at /var/run/dovecot//auth-master
by maxxfire 06 Mar '08

06 Mar '08

Hi, I'm using dovecot1.1 with postfix2.2.5; I configure dovecot.conf following the dovecot-wiki. But i doesn't work. The maillog said 'Can't connect to auth server at /var/run/dovecot//auth-master: No such file or directory' when I send a mail. my Postfix Master.cf configure: dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} I just confused that why it needed to be authed again when postfix pipe the mail to dovecot. Best regards! Thanks and forgive my poor english writing.

[Dovecot] Effects of migration
by Andy Dills 06 Mar '08

06 Mar '08

So, to follow up to my previous thread, we just successfully migrated our NFS-based mail cluster from qmail pop, courier imap, and bincimap to dovecot 1.1rc1. Overall the transition was very smooth, the only unexpected adjustment was having to implement ntpd on each box, rather than doing an hourly ntpdate against our local ntpd server, to prevent dovecot from crashing itself from too much drift. The impact has been severe! Even with NFS-stored indexes, our netapp is seeing 1/6th of the NFS ops per second, and its CPU utilization is now at 1/3rd previous levels. The only user comment thus far was thanking us for bringing IMAP folders out from under INBOX. Dovecot is truly excellent. In my book, Timo joins Wietse Venema and Marc Martinec to form the backbone of the premiere open source mail solution. For now, praise will have to suffice. I do, however, maintain a little IOU list that I intend to fulfill at some point in the future, and Timo is now high on the list. Thanks again!
