[Dovecot] patching dovecot for sieve/managesieve support, centos 5.6?
by Scott Lewis 10 Nov '11

10 Nov '11

Hi all, I am having real trouble when attempting to patch dovecot 1.2 to include the Pidgeonhole sieve support on my CentOS 5.6 x64 mail server. I am relatively new to the programming side of linux, but I am not having a lot of luck when trying to get this thing to compile. Here's what happens: [root@mail ~]# whereis dovecot dovecot: /usr/sbin/dovecot /etc/dovecot.conf /usr/lib/dovecot /usr/libexec/dovecot /usr/share/man/man8/dovecot.8.gz [root@mail dovecot-1.2-sieve-0.1.19]# ./configure --with-dovecot=/usr/lib/dovecot ... checking whether to build static libraries... yes dovecot-config not found from /usr/lib/dovecot, use --with-dovecot=PATH to give path to compiled Dovecot sources or to a directory with the installed dovecot-config file. configure: error: dovecot-config not found -- I get this message regardless of whether I set --with-dovecot as /usr/sbin/dovecot, or /etc, or /usr/libexec/dovecot. I have SquirrelMail 1.4.22 running, and the avelsieve front-end seems happy enough. when I visit https://mail.mydomain.com/src/configtest.php, I get: Avelsieve plugin details: backend = ManageSieve ERROR: I could not determine the capabilities for Sieve Mail Filtering. Perhaps connectivity with ManageSieve server (if backend=Managesieve) is bad? thanks in advance!

[Dovecot] Quota BUG ?

Hello list, I believe I found a bug with quota. The dovecot quota replies with incorrect values when the mailbox is above 2GB. du -ks returns 2005764bytes dovecot IMAP on the same user/directory: 1 getquotaroot inbox * QUOTAROOT "INBOX" "user" * QUOTA "user" (STORAGE 1096 2000000)* QUOTAROOT "INBOX" "user" * QUOTA "user" (STORAGE 1096 2000000) 1 OK Getquotaroot completed. Is there any way to fix this ? --- linux system: dovecot 1.2.15-7 linux 2.6.32-5-amd64 dovecot.conf: dict { quotadict= mysql:/etc/dovecot/dovecot-dict-quota.conf } plugin { quota = dict:user::proxy::quotadict } dovecot-dict-quota.conf : user_query = SELECT '/home/%d/%n' as home, 'maildir:/home/%d/%n' as mail, 150 AS uid, 8 AS gid, CONCAT('*:bytes=', CAST(quota AS CHAR)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1'

[Dovecot] Corrupted transaction log file
by Peter Mogensen 09 Nov '11

09 Nov '11

Hi, I'm experiencing a problem I need some pointers to debug. I'm running Dovecot 2.0.15 and have a client which keeps causing log-entries like: Nov 4 15:10:42 mail dovecot: imap (test(a)aaaone.net) Error: Corrupted transaction log file /mail/3340444/.TestMails/dovecot.index.log seq 2: indexid changed 1320419300 -> 1320419441 (sync_offset=0) Nov 4 15:10:42 mail dovecot: imap(test(a)aaaone.net): Error: Corrupted transaction log file /mail/3340444/.TestMails/dovecot.index.log seq 2: Invalid transaction log size (4476 vs 4360): /mail/3340444/. TestMails/dovecot.index.log (sync_offset=4476) Nov 4 15:10:42 mail dovecot: imap(test(a)aaaone.net): Disconnected: IMAP session state is inconsistent, please relogin. bytes=549/100474 The client issues a lot of IMAP connections like this: A1_0 LOGIN "test(a)aaaone.net" "password" A1_1 ENABLE QRESYNC CONDSTORE * OK Waiting for authentication process to respond.. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot ready. A1_0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in * ENABLED QRESYNC CONDSTORE A1_1 OK Enabled. A2_0 CREATE "INBOX.folder" A2_0 OK Create completed. A3_0 SUBSCRIBE "INBOX.folder" A3_0 OK Subscribe completed. A4_0 APPEND "INBOX.folder" ($CreatedByImapClient-test) {20487+} ... more similar appends. But it only seems to be reproducible, when there's another client involved. Starting up Thunderbird with a login to the account seems to be enough to cause this. (To my knowledge this causes a series of STATUS command and then IDLE). The installation is using Maildir and lock_method = fcntl on local disks. /Peter

[Dovecot] Please advise on very fast search
by Alexander Chekalin 09 Nov '11

09 Nov '11

Hello, I try to create some kind of mail backup system. What I need is system that will store mail for the whole domain, and allow me to restore messages from/to specified email at that domain. The scheme is pretty simple: on our main mail server the SMTP server itself has a rule to send a copy of every message to 'backup(a)backupserver.host', and the backupserver.host domain is placed nearby on second server. The SMTP on second server do simple 'catchall' redirect of all messages to the single box. There is also a Dovecot that takes care for remote IMAP access to that box. And, finally, I've create some scripts to sort all messages in INBOX to folders named after message's date. So I have a lot of mailboxes inside the catchall box: INBOX 2011.11.03 2011.11.04 2011.11.05 2011.11.06 ...etc... and each folder holds messages for that day. Simply, and works perfectly. The problem is that when my archive become big (several years), it appears to be painful to find specified message(s). When someone suddenly needs to find his/her old message, it is mostly guesses like 'I think the message was between june and july of 2009, or maybe month or two before that', so I need to search all mailboxes (with 1000's messages in each). And it takes really long time. I tried to play with Dovecot indexes, but it won't help too much. The bad part is that I need to search for all emails in each message headers, not only for "From" or "To", since some messages are sent to maillists soe "To" = list address, not person's personal email. Then I tried to index messages on my own, storing info on emails into MySQL database ('email' -> 'mailbox', 'message filename'), but soon I find out that message files can be renamed by Dovecot. Could you please advice me how to speed up message search? Sorry for such a long question, hope you can help! Yours, Alexander Chekalin

Timo, maybe you have mispelled the command? > We are using dovecot 2.0.15+mdbox+zlib and we are evaluating to buy > cheap sata-based iscsi storage / sata-NFS.

You could then sum them up with some scripting to produce the total. Unfortunately they are the uncompressed sizes, but maybe simply dividing by 2 would give approximate size? :) (You could get the compressed sizes from dovecot.map.index files with doveadm dump and mapping their contents to the older than 1 year message UIDs, but this gets difficult.)

[Dovecot] Doveadm scrip-fu to determine alternate storage needs
by Maria Arrea 09 Nov '11

Hello We are using dovecot 2.0.15+mdbox+zlib and we are evaluating to buy cheap sata-based iscsi storage / sata-NFS. We want to evaluate how much space would be needed in alternate storage BEFORE buying it. I have been reading about doveadm altmove. We want to move ALL messages older than a year to alternate storage, what doveadm-script-fu could I do to identify how much space would go from a user to alternate storage? Regards Maria
