[Dovecot] Cannot create auth-master file
by Greg Frith 09 Mar '10

09 Mar '10

Hi all, I'm trying to get postfix and dovecot working nicely together to process and store mail for both local (system) on one domain and virtual users and a few different domains. I've got postfix up and running quite nicely, but am having a few problems with Dovecot. Every time postfix tried to delivery a message to a virtual user using dovecot I get an error like the following in /var/log/mail.log: Mar 8 21:53:58 rhy postfix/pipe[6616]: 89C94846E: to=<gregf(a)gregsfamily.com>, orig_to=<greg(a)gregsfamily.com>, relay=dovecot, delay=8795, delays=8794/0.01/0/0.61, dsn=4.3.0, status=deferred (temporary failure) At the same instant, in my dovecot log I'll get this error: deliver(gregf(a)gregsfamily.com): 2010-03-08 21:53:58 Error: Can't connect to auth server at /var/run/dovecot/auth-master: Connection refused So, I'm guessing that this is a permissions issue (somewhere) and that the dovecot process is not able to create the file /var/run/dovecot/auth-master. The permissions on this folder are as follows: gregf@rhy:/etc/dovecot$ ls -al /var/run/dovecot/ total 0 drwxr-xr-x 3 root root 100 2010-03-08 21:44 . drwxr-xr-x 15 root root 660 2010-03-08 22:00 .. srw------- 1 vmail root 0 2010-03-08 21:43 auth-master srwxrwxrwx 1 root root 0 2010-03-08 21:43 dict-server drwxr-x--- 2 root dovecot 60 2010-03-08 21:44 login I've searched around for hours, found several threads describing similar issues, but no solutions that have worked for me. If anyone is able to give me any pointers or suggestions I would be most grateful. My dovecot configuration is: gregf@rhy:/etc/dovecot$ sudo dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-18-generic x86_64 Ubuntu 9.04 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login user: vmail debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes 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 :wq G

[Dovecot] Using MySQL For Mailboxes?
by Carlos Mennens 09 Mar '10

09 Mar '10

I have always seen some people indicate they use MySQL for mailboxes in Postfix and I wondered how difficult something like this would be? I have 300 users on my company Postfix server right now. I am just using Postfix, Dovecot (IMAP4 only), & Roundcube (Webmail). I have MySQL loaded on the machine that runs Postfix but only to manage the database for Roundcube. Do you think that 300+ users is recommended for a MySQL database for mailboxes? Secondly, how difficult is it to configure this? Right now everyone user has a home directory and a mailbox in their private home folder. Is it hard to configure Postfix & Dovecot to use MySQL mailboxes? Just looking for some suggestions since I couldn't find a log of info via Google. *PS* I was told that Dovecot doesn't support MySQL mailboxes. I think it does. Am I wrong? http://howtoforge.com/forums/showthread.php?p=221396#post221396

[Dovecot] Dovecot 2.0beta3: Latest HG crashed upon LMTP Delivery

Hi, unsure how to provide more useful information, as I can not get LMTP to create a core dump. With the latest changes from Mercurial it dies upon message delivery: ==> /var/log/dovecot.log <== Mar 8 20:03:33 spectre dovecot: lmtp(11690): Connect from local Mar 8 20:03:33 spectre dovecot: lmtp(11690): Connect from local Mar 8 20:03:33 spectre dovecot: lmtp(11690): Connect from local Mar 8 20:03:33 spectre dovecot: master: service(lmtp): child 11690 killed with signal 11 (core not dumped) Mar 8 20:03:33 spectre dovecot: master: service(lmtp): command startup failed, throttling Thomas

[Dovecot] Pigeonhole Sieve date extension
by Edgar Fuß 09 Mar '10

09 Mar '10

Probably I'm doing something stupidly wrong. I have dovecot 1.2.7 and sieve 0.1.13. I have a sieve script starting with # <some comment> require ["vacation", "date", "relational"]; I get main_script: line 2: error: require command: unknown Sieve capability 'date'. Just to make sure I haven't messed up the dovecot package: $ strings /usr/pkg/lib/dovecot/lda/lib90_sieve_plugin.a | fgrep date_extension date_extension date_extension date_extension date_extension date_extension What's going on? It's probably some totally stupid typo on my side.

[Dovecot] force to recalculate quotadict
by Andre Hübner 08 Mar '10

08 Mar '10

Hello, i use working quotasystem with sql-quotadict. The values stored in db are used to realize also a quotasystem in postfix to reject mails if they are bigger then remaining quota. if dataset in quotadict is missing for some reasons, postfix can't calculate quota and mail gets delivered even if user is already over quota. I am looking for a way to force dovecot/lda to recalculate users bytes/messages with command xy and not to wait for incomming mail. Currently i use: deliver -d $user -n -m folderwithunspeakablenamesonobodyusesthis and send a small message which gets lost but starts the calculation. This works but seems not to be the finest way. Is there a better way or my current procedure acceptable? Thanks, Andre

Hello, > 1. remove the quota in the DB, > 2. make same changes. hmm, i see. but unfortunately this is not a way i can do. it would be acceptable in private scope but not for bussinesscustomers. to make a change i would manipulate customers maildata which is not allowed this way. a simple command to update complete quota for the single user would be the best way. now i tried to connect per telnet and use command Getquotaroot, seems also to work. this should be scriptable... ok thanks, i will try something...

[Dovecot] Saving Sent Messages to Sent Folder
by Charles Marcus 08 Mar '10

08 Mar '10

Hi Timo, There was another thread (it has come up at least a few times in the past few years I've been lurking) on the postfix list about having some kind of automatic 'Save to Sent' option to avoid the users mail client from having to upload messages twice (obviously the only ones of concern are ones with large attachments) - once to send it, and once to save the copy in the sent folder. I know and understand that doing this is not generally the job of the MTA, but hopefully most people can at least admit that there would be a (potentially huge, in the case of any large company that deals with a lot of large attachments in their email) savings in bandwidth (and user frustration) if a way could be found to do this reliably and at little to no 'cost' in terms of CPU/Disk IO, so I have a question about how this might be done... Given: Postfix can be configured to use the Dovecot LDA for delivering mail incoming. My question is simply, why wouldn't it be possible to create a Dovecot LSA ('submission agent'), that could be defined in postfix's master.cf file, which could then be configured to a) pipe the message to postfix, and b) if message is successfully sent, save a copy to the users Sent folder? Obviously, there would be some caveats - ie, postfix and dovecot would both have to be running on the same box (or at a minimum on the same local network)... Anyway, this is just something that really bugs me (and has for many, many years) every time I send a message with a large attachment, and have to watch it slowly process the message sending it, then again to save it to the Sent folder, so Ijust wanted to get your take on if this is even remotely feasible... -- Best regards, Charles
