[Dovecot] script to detect dictionary attacks
by Reindl Harald 09 Apr '13

09 Apr '13

Hi has someone a script which can filter out dictionary attacks from /var/log/maillog and notify about the source-IPs? i know about fail2ban and so on, but i would like to have a mail with the IP address for two reasons and avoid fail2ban at all because it does not match in the way we maintain firewalls * add the IP to a distributed "iptables-block.sh" and distribute it to any server with a comment and timestamp * write a abuse-mail to the ISP

[Dovecot] "No such file or directory" error setting up dict quota for mdbox
by ADRIAN SANTOS MARRERO 09 Apr '13

09 Apr '13

Hi, I've some troubles setting up the dict based quota plugin for mdbox, it always returns a error when lmtp tries to deliver an e-mail: Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre(a)ull.es) Error: fstat(/sharedfs/10.4.1.107/ull.es/54/asmarre/dovecot-quota.lock) failed: No such file or directory Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre(a)ull.es) Error: file dict commit: file_dotlock_open(/sharedfs/ 10.4.1.107/ull.es/54/asmarre/dovecot-quota) failed: No such file or directory Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre(a)ull.es) Error: dict quota: Quota update failed, it's now desynced In fact lmtp does create the dovecot-quota.lock file but it does not update the dovecot-quota file. If I run "doveadm quota recalc -u asmarre" it works and updates the dovecot-quota file. The version of dovecot that I'm using is 2.0.19 and the configuration is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-32-generic x86_64 Ubuntu 12.04.2 LTS mail_debug = yes mail_location = mdbox:%h mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { quota = dict:User quota::file:%h/dovecot-quota quota_rule = *:storage=1G quota_warning = storage=95%% quota-warning 95 quota_warning2 = storage=85%% quota-warning 85 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)ull.es protocols = " imap lmtp sieve pop3" service lmtp { inet_listener lmtp { port = 24 } } service managesieve-login { inet_listener sieve_deprecated { port = 2000 } } service quota-warning { executable = script /opt/ccti/correo/buzones/quota_warning.sh unix_listener quota-warning { user = dovecot } user = dovecot } ssl_cert = </etc/ssl/certs/www.ull.es.chain.crt ssl_key = </etc/ssl/private/www.ull.es.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve zlib } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_no_flag_updates = yes pop3_uidl_format = %v.%u } Thanks in advance.

[Dovecot] LMTP Setup/Design Help Request
by Matthias Hofer 09 Apr '13

09 Apr '13

Hi altogether, I am switching from dbmail 2.2 to dovecot 2.1.7, and I was able to do a successful transition of IMAP. But I had a very hard time with receiving mail, and in the end -- after loads of reading and debugging -- I broke down and failed. This is why I am asking you for your kind help. I only have virtual users and have set mail_uid = dovemail mail_gid = dovemail For authentication, I simply use (for now) a flat file: passdb { driver = passwd-file args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file } # cat /etc/dovecot/mypasswd.file user1:{PLAIN}userpw1 user2:{PLAIN}userpw2 user3:{PLAIN}userpw3 And everything works fine with IMAP. I am completely domain-agnostic here. But I was not able to use this fine setup to receive mails with my postfix. I tried about 13 different configurations, some with considerable changes dovecot-config, the passwd-file or postfix, but I could not find a single variant working. In this situation, I would be very happy if somebody could give me a hint, which would be the prudent way to configure dovecot, LDA/LMTP and postfix based on the setup above. Thank you very much in advance, and have a great time, Matthias Hofer

[Dovecot] repeating dsync - questions
by Bob Gustafson 08 Apr '13

08 Apr '13

I'm moving/converting email from one system to another The source system is: Dual core x86_64 6GB memory 180 GB raid1 disks ext4 Fedora 9 Dovecot 1.0.15 Maildir format The destination system is: Dual core x86_64 2GB memory 1TB raid1 disks ext4 Fedora 18 Dovecot 2.1.15 sdbox format I am moving mail in a series of steps: 0) cd ( to mail user home directory ) mkdir Maildir 1) # rsync mail from source system (hoho4) to current (hoho0) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/ This step takes about 37 minutes the first time 2) # dsync mirror/convert to sdbox format on current system time dsync mirror maildir:~/Maildir This step takes about 858 minutes (!!) Looking at -D messages indicates that dsync is deciding between duplicates much of the time. Looking at the results in a mail browser (Evolution), it seems fine, although the latest mails are not there. 3) # pick up more current mail - use same script as in 1) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/ This step takes about 5 minutes although this varies depending on the amount of new mail. 4) # repeat the 2) dsync step time dsync mirror maildir:~/Maildir This is where things look peculiar. When I look at the directory of sdbox/mailboxes, I see duplicated directories [bobgus@hoho0 sdbox]$ cd mailboxes [bobgus@hoho0 mailboxes]$ ls Apple Mail To Do Apple Mail To Do_2a47983780615e5179600000ba55d82c Deleted Messages Deleted Messages_2847983780615e5179600000ba55d82c Drafts Drafts_2447983780615e5179600000ba55d82c Important Important_2947983780615e5179600000ba55d82c INBOX INBOX_1547983780615e5179600000ba55d82c Sent Sent_2547983780615e5179600000ba55d82c Trash Trash_2747983780615e5179600000ba55d82c The 2nd dsync step has not completed yet. I'm wondering whether the extra directory will be magically moved into the older directory. (This is unlikely because the file names are duplicated in the new directory) ------- Is this expected behavior? Are there command changes I can make to speed up the process? Eliminate the duplicate directories?

Hi, I am trying to use separate configurations for ldap authentication thus providing users with the ability to only use username without domain part. Now according to documentation this should be possible http://wiki2.dovecot.org/AuthDatabase/PasswdFile but I keep getting error in my dovecot.log like this auth: Error: Can't open configuration file /etc/dovecot/%l/dovecot-ldap.conf: No such file or directory Why does dovecot does not expand %l to local ip address?

[Dovecot] dsync replication: quota counted twice
by Oli Schacher 08 Apr '13

08 Apr '13

Hi I enabled quota + warnings in my replication test setup and now whenever a mail gets delivered the quota is counted twice (probably due to both servers using the same mysql quota backend) and quota warnings are fired too early. After a doveadm quota recalc -u <username> the quota is correct again. How do I make dovecot only count the quota on the server where the mail was added originally? dovecot -n is the same as in my previous message to the list today http://www.dovecot.org/list/dovecot/2013-April/089558.html (thanks Timo for the hint in this thread btw, changing the permissions made the errors go away) Thanks Oli -- message transmitted on 100% recycled electrons

[Dovecot] Dovecot Configuration
by Andreas K. 08 Apr '13

08 Apr '13

Can somebody, please, point me in the right direction in finding a COMPLETE and EXACT definition of the Dovecot configuration hierarchy. In other words what configuration options exist both at the top level but also at each subconfiguration elements (ex. sections etc). While my C is a bit rusty, I can still make sense of source code and with a bit of effort I will figure it out. I have been going through the src/config/all-settings.c but still have large gaps. A hint in the right direction on how the config works might help clarify and speed things up. Thanks Andreas Kasenides

[Dovecot] Problem with fts lucene, on solaris 10

Hi all, I'm planning to migrate my courier-imap imap server to dovecot, but I'm experiencing a strange issue with fts-lucene plugin. Basically, every time I start a search, the log starts to write: Apr 05 19:30:53 indexer: Error: Indexer worker disconnected, discarding 1 requests for XXXXXX Apr 05 19:30:53 indexer-worker(XXXXX): Fatal: master: service(indexer-worker): child 809 killed with signal 11 (core not dumped) Apr 05 19:30:53 imap(XXXXXX): Error: indexer failed to index mailbox INBOX Apr 05 19:30:56 indexer-worker(XXXXX): Error: lucene index /home/XXXXX/Maildir/lucene-indexes: IndexWriter() failed (#1): Lock obtain timed out When trussing the indexer-worker pid I can see it ends with: ...SNIP... 527: brk(0x005A7840) = 0 527: brk(0x005AD840) = 0 527: pread64(16, " I G E N E R I C I < /".., 8170, 24514) = 8170 527: brk(0x005AD840) = 0 527: brk(0x005B3840) = 0 527: Incurred fault #5, FLTACCESS %pc = 0xFEBD6DDC 527: siginfo: SIGBUS BUS_ADRALN addr=0x005B50BA 527: Received signal #10, SIGBUS [default] 527: siginfo: SIGBUS BUS_ADRALN addr=0x005B50BA I cannot get a core, but either root ( user that is starting the dovecot ) than the user XXXXX have unlimited coresize XXXXX /home/XXXXXXX > ulimit -a time(seconds) unlimited file(blocks) unlimited data(kbytes) unlimited stack(kbytes) 8192 coredump(blocks) unlimited nofiles(descriptors) 256 vmemory(kbytes) unlimited root # ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 10 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 29995 virtual memory (kbytes, -v) unlimited The mailbox for user XXXXXX ( Maildir stile, for speed-up migration ) has ~ 4000 messages.
