[Dovecot] courier-dovecot-migrate.pl maintaining order of pop3 uidl's
by Mark Zealey 05 Jan '11

05 Jan '11

Hi there, I've just been experimenting with the latest courier-dovecot-migrate.pl script and I notice that it favours keeping pop3 UIDL ordering rather than IMAP UID preservation. There is this comment (line 312): # POP3 clients may want to get POP3 UIDLs in the same order always. # Preserve the order even if it causes IMAP UIDs to change. Does anyone have details as to which clients this actually causes a problem with? If it's some really old software then perhaps we'd prefer to keep the imap UID's the same but change the POP3 UIDL ordering (not the UIDL numbering though of course) Thanks, Mark

[Dovecot] dovecot 2.0.8 defaults to require ipv6 ?
by Jan-Frode Myklebust 05 Jan '11

05 Jan '11

FYI it seems dovecot 2.0.8 fails to start on RHEL5 with IPv6 disabled ("alias net-pf-10 off" in modprobe.conf) unless one specify "listen = *". Not sure if this is a known problem, or just a hint that we should start enabling ipv6 on our mailservers... ;-) -jf

[Dovecot] dovecot v1.2.15 - Unknown dict module: quota - Fatal: Quota root storage=200000 proxy init [postfix, dovecot LDA, postfixadmin, mysql]
by JKL 05 Jan '11

05 Jan '11

Dear everyone, I am trying to get my Email set-up to work, and wonder if someone would shed some light onto this? Best regards, J. ------------------------------------------------------------------ Set-up is : postfix -> dovecot LDA -> mysql <- postfixadmin What works: postfix delivers to dovecot. postfixadmin is configured, and have created one domain test.info. What is broken: dovecot is mis-configured. postfixadmin might well be mis-configured. I have followed the instructions in the postfixadmin/DOCUMENTS/DOVECOT.TXT for the additional dovecot configuration. *** ERROR MESSAGES All Emails passed from postfix to dovecot generate: Jan 4 20:35:02 logout dovecot: deliver(test(a)test.info): Unknown dict module: quota Jan 4 20:35:02 logout dovecot: deliver(test(a)test.info): Fatal: Quota root storage=200000 proxy init() failed Jan 4 20:57:18 logout dovecot: IMAP(test(a)test.info): mkdir(/var/mail/vmail/test.info/test(a)test.info/cur) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/mail) ** DOVECOT -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-xxxxxxxx-xxxxx x86_64 Debian squeeze/sid log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_chroot: no first_valid_uid: 106 mail_privileged_group: mail mail_location: maildir:/var/mail/vmail/%d/%u/ mbox_write_locks: fcntl dotlock lda: log_path: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)test.info mail_plugins: sieve quota auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes userdb: driver: sql args: /etc/dovecot/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: 384 user: vmail plugin: quota: dict:storage=200000 proxy::quota quota: dict:storage=200000 proxy::quota:w dict: quota: mysql:/etc/dovecot/dovecot-dict-quota.conf *** MYSQL DOVECOT FILES # grep -v '^ *$#.*$\?$' dovecot-sql.conf connect = host=localhost dbname=xxxxx user=xxxxx password=xxxxx driver = mysql default_pass_scheme = MD5-CRYPT password_query = SELECT username AS user,password FROM mailbox WHERE username = '%u' AND active='1' user_query = SELECT CONCAT('/var/vmail/', maildir) AS home, 106 AS uid, 110 AS gid, CONCAT('*:bytes=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active='1' ## Note: 106:110 = postfix:avahi For some reason squeeze drops postfix into avahi group: To Fix. *** DICT QUOTA # cat /etc/dovecot/dovecot-dict-quota.conf driver = mysql connect = host=localhost dbname=xxxxx user=xxxxx password=xxxxx default_pass_scheme = MD5-CRYPT table = quota select_field = current where_field = path username_field = username *** /VAR/VMAIL directory # ls -la /var/vmail total 28 drwxrwx--- 3 vmail vmail 4096 Jan 4 20:53 . drwxr-xr-x 15 root root 4096 Jan 3 12:19 .. -rw-r--r-- 1 root root 0 Jan 3 15:14 auth_socket_path -rw-r--r-- 1 root root 173 Dec 31 12:15 globalsieverc -rw-r--r-- 1 root root 0 Jan 3 15:14 info_log_path -rw-r--r-- 1 root root 0 Jan 3 15:14 log_path drwx------ 2 root root 16384 Jan 4 15:28 lost+found -rw-r--r-- 1 root root 0 Jan 3 15:14 mail_plugins -rw-r--r-- 1 root root 0 Jan 3 15:14 postmaster_address *** VMAIL user vmail:x:5000:5000::/var/vmail:/bin/sh (soon to be changed to /bin/false after testing completed) dovecot:x:109:114:Dovecot mail server,,,:/usr/lib/dovecot:/bin/false postfix:x:106:110::/var/spool/postfix:/bin/false

[Dovecot] Lazy expunge for performance ?
by Jan-Frode Myklebust 05 Jan '11

05 Jan '11

Some filesystems are quite slow at deleting files, so I'm wondering if anybody is using the lazy expunge plugin to implement a solution where expunged messages are moved to a separate directory structure within the same filesystem, and later deleted as a nighly batchjob ? Assuming expunge renames/moves messages, and don't do a copy + delete.. Does something like this make sense ? -jf

[Dovecot] dovecot + sendmail, what LDA setup?
by David Cake 05 Jan '11

05 Jan '11

I have an existing setup with sendmail, dovecot, on debian. I want to move LDA and move from using mbox to using Maildir. I have only 'real' users and aliases, no virtual users. What is a recommended, trouble free, LDA setup? procmail is of course on possibility, but I'd be unlikely ever to use any of its advanced features, just simple local mail delivery. I'd like to use deliver, but most of the dovecot as LDA sample configs I have seen seem to assume I am using it for virtual users. Advice? Pointers to a simple working setup for sendmail, dovecot, Maildir? Cheers David

[Dovecot] re-indexing moved mail
by Phil Howard 05 Jan '11

05 Jan '11

I have a huge block of email that was misdelivered into the wrong folder. Moving it where it should be is not just all from one folder to being all of another folder. Basically, the index files need to be rebuilt. Looking in the wiki I cannot find how to do this. It all seems to be about installation, and no administrative tools. Or would it be just as simple as delete certain index files and they would be automagically rebuilt? -- sHiFt HaPpEnS!

[Dovecot] Error copying >1 message to virtual mailbox
by Nicholas Riley 05 Jan '11

05 Jan '11

I created a virtual mailbox which maps to a single physical mailbox (in Dovecot 1.x I did this with a symlink but had intermittent problems with Dovecot 2.0 doing the same.) However, I can only copy one message at a time into the mailbox. If I try to copy more, I get: 7.16 UID COPY 48531:48532 !/Saved 7.16 NO [CANNOT] Can't save messages to this virtual mailbox whereas this works fine: 10.16 UID COPY 48531 !/Saved 10.16 OK Copy completed. The dovecot-virtual file in !/Saved is: !2011-01 all and dovecot.conf: # 2.0.8 (cde0d403c6ff): /etc/dovecot/dovecot.conf # OS: Linux 2.6.18.8-linode22 i686 Debian 5.0.7 mail_location = maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX:CONTROL=~/.dovecot.cont rol:SUBSCRIPTIONS=.subscriptions mail_max_userip_connections = 20 namespace { inbox = yes location = prefix = separator = / } namespace { location = virtual:~/Maildir/! prefix = !/ separator = / } passdb { driver = pam } plugin { antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_spam_pattern_ignorecase = *spam } protocols = imap ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " virtual" } Thanks. -- Nicholas Riley <njriley(a)illinois.edu>
