[OT] Extdata / Extprograms Plugins on CentOS 7?
by E.B. 04 Mar '15

04 Mar '15

Hello, I want to install Dovecot Pigeonhole and use the Extdata and Extprograms plugins on CentOS 7. I prefer to install software via yum, and a reasonably new version of Dovecot is available in the CentOS repo. But according to the dovecot documentation, these plugins need to be compiled, so I don't know if yum is out of the question? * Does anyone know if either of these plugins built into the Pigeonhole that is available in the CentOS 7 extras repo? OR if there is a version of Pigeonhole available in a different 3rd party repo with what I want? (like EPEL, DAG, etc) * Is it possible to use these plugins with Pigeonhole installed from yum? Does the compilation requirement mean that I have to remove not only Pigeonhole, but also Dovecot itself from my system and build everything by hand? :-( THANK YOU!!!!!!

Hello, about the CVE-2015-0204, in apache the following config seems to disable this vulnerability: SSLProtocol All -SSLv2 -SSLv3 SSLCipherSuite HIGH:MEDIUM:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4 Is something similar possible with dovecot ? If yes, what are the implications with old mail clients ? -- Best regards, Adrian Minta

Re: Rebuilding SIS attachment links from log

Well, with no guarantees or promises whatsoever...here's my first attempt. I'm certain someone else can come up with a much more robust solution but it's a starting point. Since I typically see a batch of the error messages during an FTS update, my current usage is: 1. doveadm fts rescan -u user-to-fix 2. Perform a fts search to do a full mailbox scan 3. Check the mail log to see the date/time of the errors (I usually have a window open with tail -f) 4. Something like "grep 'Mar 3 20:17' mail.log > mail.err" gives me a starting point execute dovesisfix and see if it helps. -- Daniel On 3/3/2015 1:08 PM, Daniel Miller wrote: > This seems simple enough...I'm just not script wizard.

ot: maildir has overdrawn his diskspace quota

I have Postfix/Dovecot with virtual domains, same setup unaltered since server was set up quite a while ago last month, added a new virtual domain, 'just like before'. but, today noticed this in the queue/log 'overdrawn his diskspace quota'[1]: user's Maildir cur has like 48,762,696 bytes (lot less than other users) tried some searches, found similar probs, but, no solution as yet any ideas ? after physically removing some emails from this user's 'cur', I re-queued 'stuck' message, it was then accepted # quota -g vmail # quota -u vmail # [1] # grep 719855FC42 /var/log/maillog Mar 3 15:20:58 emu postfix/smtpd[18535]: 719855FC42: client=mail-pa0-f51.google.com[209.85.220.51] Mar 3 15:20:58 emu postfix/cleanup[18631]: 719855FC42: message-id=<54f536ad.21da440a.6572.3c07(a)mx.google.com> Mar 3 15:21:01 emu postfix/qmgr[1906]: 719855FC42: from=<dsome1(a)gmail.com>, size=5487190, nrcpt=1 (queue active) Mar 3 15:21:01 emu postfix/virtual[20248]: 719855FC42: to=<anna(a)tld.com>, relay=virtual, delay=3.5, delays=3.4/0/0/0.08, dsn=4.2.2, status=deferred (maildir delivery failed: Sorry, the user's maildir has overdrawn his diskspace quota, please try again later.)

I'm agnostic as far as which method you want to use. All I'm saying is that using dovecot's allow_net facility is as difficult, if not more so, than letting your firewall handle it.

Connect failed to database
by Dan LaSota 03 Mar '15

I have dovecot version 2.2.10 dovecot -n output below I am seeing connection errors being written to my dovecot error log: Mar 1 19:51:15 mail dovecot: auth-worker(2224): Error: mysql(localhost): Connect failed to database (servermail): Access denied for user 'usermail'@'localhost' (using password: YES) - waiting for 5 seconds before retry My connection script located at /etc/dovecot/dovecot-sql.conf.ext is like (password edited): driver = mysql connect = host=localhost dbname=servermail user='usermail' password='MY_SUPER_SECRET_PASSWORD' default_pass_scheme = SHA512-CRYPT password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; I have verified that I can gain access to the SQL database with # mysql -u usermail -p I can make select statements on the 'servermail' database and all of its tables. I've searched for similar errors from users, but most of the questions are unanswered, or answered incorrectly. I did follow one thread's suggest of setting the MYSQL password for the 'usermail' with OLD_PASSWORD instead of PASSWORD. I did that. I could still login from the shell using mysql -u usermail -p But dovecot still wrote the same error. (I did a flush privileges, and restarted mysql, and dovecot) I then set the password in SQL back using PASSWORD. (flush'd priveleges and restarte mysql and dovecot). Still Errors. Looking for leads.

problem with dovecot/lmtp
by Dan LaSota 03 Mar '15

03 Mar '15

I am getting this in my errorlog for postfix/dovecot Mar 2 16:42:14 mail postfix/error[5074]: A689580F236: to=<root(a)mail.example.com>, relay=none, delay=21420, delays=21420/0.05/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to mail.example.com[private/dovecot-lmtp]: Connection refused) From my reading, I believe this has something to do with virtual_transport which I have set to: virtual_transport = lmtp:unix:private/dovecot-lmtp The socket file, exists: [root@mail ~]# ls -l /var/spool/postfix/private/dovecot-lmtp srw-------. 1 postfix postfix 0 Mar 2 09:14 /var/spool/postfix/private/dovecot-lmtp But I'm a little stumped as how to proceed. The only thing I think I understand is that postfix is trying to talk to dovecot-lmtp and dovecot-lmtp is refusing the connection. Am I reading that correct? What can I do about it?

Postfix - dovecot-lda -> Permission denied
by Wöltje, Marcus 02 Mar '15

02 Mar '15

Hi erveryone! I'm trying to run Postix and Dovecot on a Mac OS X, but somehow, it doesn't work. I probably messed up the privileges or something else. Hopefully someone of you, can help me figure it out. So far, Postfix is delivering the mail into ~/Maildir. But as soon as I add the line: mailbox_command = /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/dovecot-lda in /etc/postfix/main.cf I get the following entry in the mail.log. Feb 27 16:08:02 Nils-iMac.local local[53237]: fatal: execvp /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/dovecot-lda: Permission denied Feb 27 16:08:02 Nils-iMac.local postfix/local[53236]: B246837BE40: to=<marc(a)localhost.local>, orig_to=<marc@localhost>, relay=local, delay=1185, delays=1185/0.01/0/0.01, dsn=4.3.0, status=deferred (temporary failure.

Re: Dovecot & LDAP Take #2: Authentication failed and logging
by Paolo Cravero 02 Mar '15

This is the user DN: > cn=Klara Fall,ou=People,dc=[domainname],dc=de According to your Dovecot configuration > auth_bind_userdn = cn=%u,ou=People,dc=**[domainname]**,dc=de if you login with "klarafall" it will be expanded into cn=klarafall,ou=People,dc=[domainname],dc=de which is not the correct DN for Mrs Klara. So if you login with "Klara Fall" it should work, but that will probably mess up the things on Dovecot filesystem. I am strongly against setting a static DN when dealing with LDAP authentication. LDAP servers are optimized to serve search requests, so let yours do the job. Allow Dovecot to lookup the correct DN based on the attribute you supply (uid) and then authenticate. This should be achieved if you comment out the auth_bind_userdn line. Paolo Cravero
