[Dovecot] imap2json
by Kai Hendry 05 Feb '14

05 Feb '14

Hi there, I've started work on a side project that I've been long wanting to do; better HTML archives of email. https://github.com/kaihendry/imap2json I'm just designing the JSON schema atm, and I thought it would be good to get your feedback (Esp Timo) before I make a horrible mistake. https://github.com/kaihendry/imap2json/blob/master/JSON-design.mdwn Is it a good idea to base the id of a converation by the sha1sum of the first message for example? Any other tips or words of encouragement would be great. Kind regards,

[Dovecot] Applying a DNS RBL to deny authentication?
by Marc Perkel 05 Feb '14

05 Feb '14

Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication. We do front end spam filtering for thousands of domains and I decided to advertize authentication where there is none and I accept and blackhole all authenticated email to those servers. I have harvested the IP addresses in this list that is available through an RBL. It seems to me that a nice dovecot feature would be the ability to do a black list check against IP addresses connecting and deny access if listed. Thoughts?

[Dovecot] dsync backup; compressed to uncompressed
by Michael Smith (DF) 04 Feb '14

04 Feb '14

I need to backup some of the mailboxes on our system. We are currently using mdbox with zlib compression plugin. The backups need to be maildir without compression. How can I accomplish this using dsync? The following just causes each msg file in maildir to be compressed as well. dsync -f -u user1 backup maildir:/var/tmp/user1 While this just causes the dsync to fail while spewing a bunch of errors because it can no longer read the compressed mdbox files. dsync -f -u user1 -o mail_plugins= backup maildir:/var/tmp/user1 # doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_debug = yes auth_debug_passwords = yes auth_default_realm = domain1.net auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/dovecot-debug.log disable_plaintext_auth = no dotlock_use_excl = no lda_mailbox_autocreate = yes lock_method = dotlock mail_access_groups = mail mail_debug = yes mail_fsync = always mail_location = mdbox:~/mail:INDEX=~/index mail_plugins = quota zlib mail_privileged_group = mail 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 mbox_read_locks = dotlock mbox_write_locks = dotlock mdbox_rotate_interval = 1 weeks mdbox_rotate_size = 20 M mmap_disable = yes namespace { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Drafts autosubscribe4 = Sent autosubscribe5 = INBOX mail_max_userip_connections = 10 managesieve_max_line_length = 65536 quota = dict:User quota::file:%h/dovecot.quota quota2_rule = Trash:storage=+10%% quota3_rule = Junk:storage=+20%% quota_rule = *:storage=100M:messages=100000 recipient_delimiter = + sieve_before = /var/opt/mail/global.sieve/ zlib_save = gz zlib_save_level = 9 } pop3_reuse_xuidl = yes protocols = imap pop3 sieve lmtp service auth { inet_listener auth { port = 113 } unix_listener auth-userdb { user = nobody } } service lmtp { inet_listener lmtp { port = 24 } process_min_avail = 10 service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota zlib sieve } protocol imap { mail_plugins = quota zlib imap_quota } protocol sieve { mail_max_userip_connections = 10 mail_plugins = quota zlib managesieve_max_line_length = 65536 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 } protocol lmtp { mail_plugins = quota zlib sieve }

[Dovecot] BLF-CRYPT passwords
by KT Walrus 04 Feb '14

04 Feb '14

I’m using the Dovecot Enterprise Edition on Centos 6.5, but Blowfish password hashes don’t seem to work. What can I do to enable Blowfish hashes for passwords? Maybe I don’t have my installation configured properly? Note that I really want to use the existing Blowfish hashes in my MySQL database for Dovecot Authentication. The hashes are generated by PHP crypt() that has Blowfish support built-in. I looked at PHP’s sources, and PHP uses crypt_blowfish.c from http://www.openwall.com/crypt/. This code is in the public domain and could easily be used by Dovecot to support Blowfish passwords on all platforms (if Dovecot doesn’t already support Blowfish on all platforms). Kevin

[Dovecot] mail_log_events, but who exactly triggered events?
by Arkadiusz Miśkiewicz 04 Feb '14

04 Feb '14

Hi. mail_log_events is nice addition but how to log who exactly triggered particular event? For example 5 users from 5 IP addresses uses single imap user/mailbox. One of them deletes email and I'm logging delete related events. The only logged thing is: dovecot: imap(user): delete: box=INBOX, uid=673287, msgid=<some@thing>, size=1230 which tells me nothing about who triggered it actually (note all 5 users were logged in at deletion time) How to solve this problem? Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl
