13 Sep '13

Dear all, I installed "dovecot dovecoot-mysql postfix and postfix-mysql" from debian repository 7. I start them with "/etc/init.d/postfix start" and "/etc/init.d/dovecot start" but When i use nmap localhost I see the following output: root@sito:/etc/dovecot# nmap localhost Starting Nmap 6.00 ( http://nmap.org ) at 2013-09-12 07:35 IRDT Nmap scan report for localhost (127.0.0.1) Host is up (0.0000030s latency). Other addresses for localhost (not scanned): 127.0.0.1 Not shown: 993 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 25/tcp open smtp 80/tcp open http 111/tcp open rpcbind 3128/tcp open squid-http 3306/tcp open mysql My Question is , Where's dovecot ? i don't see its' ports....

by Mohsen Pahlevanzadeh 13 Sep '13

13 Sep '13

Dear all, I install postfix ,postfix-mysql,dovecot-core,dovecot-mysql,dovecot-pop3,dovecot-imapd and postfixadmin form debian repo. Also i configured postfixadmin. It work fine with mbox storage, But i need to change it to my path/domain/users i saw devecot have mail_location directive. i changed it to : mail_location = maildir:/var/pool/%d/%u My questions are: 1. how can i assign mail_location directive to a maildir storage according to my path and domain/user , such as qmail? 2. i want to mysql, i need to write bash script to add/delete/update for doing them ? or dovecot provides them with command line? 3. What's permission of path in mail_location ? 4. How can i enable mysql in dovecot? My dovceconf -n is: ////////////////////////////////////// # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 ext4 mail_location = maildir:/var/pool/Maildir/%d/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } ///////////////////////////////////////////////////// Yours, Mohsen

[Dovecot] Problem getting a dovecot proxy to connect to another dovecot machine via STARTTLS
by Arnoud van Heuvelen 12 Sep '13

12 Sep '13

Hi, I'm having a bit of a problem trying to setup a dovecot proxy. I have a setup with two nodes. One is a working Dovecot/Postfix mail server (node a). The other is running a dovecot proxy and roundcube webmail. Currently I can telnet to port 143 (or openssl s_client to port 993) to localhost on node b. I can then login to a test account on node a. This all works. However, once I instruct the proxy to use SSL or TLS my problems start. When I try to login on node b (both on port 143 and 993), it will send two TCP packets on port 993 to node a. There is no TLS handshake. Consequently, my telnet session will just hang until dovecot reaches a timeout. It will then disconnect me for inactivity. I can not find any information in the logs. To clarify, the dialog: Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot ready. a login atest(a)company.nl test123 * BYE Disconnected for inactivity. I have tried to use the following values in my proxy database: ssl='any-cert', starttls='Y' ssl='any-cert', starttls='any-cert' ssl=NULL, starttls='any-cert' Here is a strace of the imap-login process on node B: http://dpaste.com/1377232/ The illegal seek on line 30 of the strace looked suspicious to me. Here is the corresponding lsof: http://dpaste.com/1377239/ Here is node A's config: http://dpaste.com/1377247/ And here is node B's: http://dpaste.com/1377241/ This is node B's password query: password_query = SELECT NULL AS password, 'Y' AS nopassword, host, 'Y' as proxy, starttls, `ssl`, 10 AS proxy_timeout FROM proxy WHERE domain = '%d' The logs tell me the password query succeeds: Sep 12 16:32:35 auth-worker: Debug: sql(atest(a)company.nl,127.0.0.1): query: SELECT NULL AS password, 'Y' AS nopassword, host, 'Y' as proxy, starttls, `ssl`, 10 AS proxy_timeout FROM proxy WHERE domain = 'company.nl' Sep 12 16:32:35 auth: Debug: client out: OK 1 user= atest(a)company.nl host=31.CENCOR p roxy starttls=Yt ssl=any-cert proxy_timeout=10 pass=test123 Nothing after that. Node A's log gives me this: 2013-09-12 16:26:51 imap-login: Info: Disconnected (no auth attempts): rip=149.CENCORED, lip=31.CENCORED, TLS handshaking: Disconnected I'm running out of ideas. If anyone would be able to help I would be extremely grateful. Regards, Arnoud van Heuvelen

I think it's something more. Apparently it's not even looking at the database. Not sure what I didn't do. If anyone can point me to a good dovecot / mysql quota how to that would be helpful.

Hello, to build dovecot-2.2.5 on a system based on openssl-0.9.7 I had to apply the attached patch.

[Dovecot] Quota question.
by Bruce Markey 12 Sep '13

12 Sep '13

I have quotas setup with dovecot. Everything seems to be running fine. Values show up fine in mysql. I set up Roundcube to show quota amounts, this also works. For some reason it's showing the old value, I had upped a quot I assume that dovecot is reporting this wrong since roundcube talks to dovecot for its info. Imap debug info: [11-Sep-2013 15:57:47 +0000]: [5986] S: A0003 OK List completed. [11-Sep-2013 15:57:47 +0000]: [5986] C: A0004 GETQUOTAROOT INBOX [11-Sep-2013 15:57:47 +0000]: [5986] S: * QUOTAROOT "INBOX" "User quota" [11-Sep-2013 15:57:47 +0000]: [5986] S: * QUOTA "User quota" (STORAGE 81 256000) [11-Sep-2013 15:57:47 +0000]: [5986] S: A0004 OK Getquotaroot completed.

[Dovecot] slow dict lookups?
by Anand Kumria 12 Sep '13

12 Sep '13

Hi, I am beginning to see many entries like: Sep 10 21:32:06 mail1 dovecot: imap(user1(a)example1.com): Warning: read(/var/run/dovecot/dict): dict lookup took 20 seconds Sep 10 21:32:11 mail1 dovecot: imap(user2(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 25 seconds Sep 10 21:32:16 mail1 dovecot: imap(user3(a)example3.com): Warning: read(/var/run/dovecot/dict): dict lookup took 30 seconds Sep 10 21:32:21 mail1 dovecot: imap(user3(a)example3.com): Error: read(/var/run/dovecot/dict) failed: Timeout after 30 seconds Sep 10 21:32:21 mail1 dovecot: imap(user1(a)example1.com): Warning: read(/var/run/dovecot/dict): dict lookup took 25 seconds Sep 10 21:32:21 mail1 dovecot: imap(user4(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 24 seconds Sep 10 21:32:26 mail1 dovecot: imap(user5(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 29 seconds What is the best way to look into making dict lookups faster? In my case the dict is use for user / domain quotas and is looked up via Postgres (on another host). Is there further logging I can enable to see where the problem is? Thanks, Anand

[Dovecot] Double Maildir folders.
by Bruce Markey 12 Sep '13

12 Sep '13

Somehow in setting up quotas and sieve I somehow doubled my maildir. I noticed that when I logged into my webmail I didn't see the folders I created. I went to the actual location and noticed this. Mail location is set correctly in 10-mail.conf mail_location = maildir:/var/vmail/%d/%n/Maildir So I went to /var/vmail/domain/user and saw: drwx------ 8 vmail vmail 4.0K Sep 11 22:08 . drwx------ 4 vmail vmail 4.0K Sep 10 18:40 .. drwx------ 5 vmail vmail 4.0K Sep 11 22:04 .Sent lrwxrwxrwx 1 vmail vmail 21 Sep 11 15:44 .dovecot.sieve -> sieve/roundcube.sieve -rw------- 1 vmail vmail 199 Sep 11 15:45 .dovecot.svbin drwx------ 10 vmail vmail 4.0K Sep 11 18:40 Maildir drwx------ 2 vmail vmail 4.0K Sep 11 19:46 cur -rw------- 1 vmail vmail 51 Sep 11 19:47 dovecot-uidlist -rw------- 1 vmail vmail 8 Sep 11 19:47 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 Sep 11 19:46 dovecot-uidvalidity.5230c8a2 -rw------- 1 vmail vmail 248 Sep 11 19:47 dovecot.index.log -rw------- 1 vmail vmail 24 Sep 11 19:47 dovecot.mailbox.log -rw------- 1 vmail vmail 15 Sep 11 22:08 maildirsize drwx------ 2 vmail vmail 4.0K Sep 11 19:46 new drwx------ 3 vmail vmail 4.0K Sep 11 15:44 sieve -rw------- 1 vmail vmail 5 Sep 11 19:47 subscriptions drwx------ 2 vmail vmail 4.0K Sep 11 19:46 tmp Which I shouldn't see correct?

As above the maildir is correct. The only two places I can think are 90-plugin.conf which are my sieve settings. plugin { # The location of the user's active script: sieve = ~/.dovecot.sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve # The include extension fetches the :personal scripts from this # directory. When ManageSieve is used, this is also where scripts # are uploaded. sieve_dir = ~/sieve # The include extension fetches the :global scripts from this # directory. sieve_global_dir = /var/lib/dovecot/sieve/global/ } But I don't see how that would affect it. And the password and user queries were changed for the quotas. password_query = SELECT username AS user, password,CONCAT('/var/vmail/', maildir) AS userdb_home,\ '5000' AS userdb_uid, '5000' AS userdb_gid,\ concat('*:storage=', quota) AS userdb_quota_rule\ FROM mailbox WHERE username='%u' AND domain='%d' AND active=1 user_query = SELECT CONCAT('/var/vmail/', maildir) AS home, 'maildir:~/' as mail, '5000' AS uid, '5000' AS gid,\ concat('*:storage=', quota) AS quota_rule\ FROM mailbox WHERE username='%u' AND domain='%d' AND active=1 maildir in the mailbox is domain/user/ <- do I have to concat on Maildir in the query?
