Easy enough to test. It's non-RFC compliant as one poster points out, so unless you got a good reason to do this like lots of zombie pop3 processes, leave it alone.

[Dovecot] Dovecot sieve and duplicate email subjects
by Benjamin Thomas 17 Oct '12

17 Oct '12

Hi, I'm running a small email server with the help of iRedMail. I can manage sieve scripts from the Rouncube web interface or manually inside the user's personal sieve folder. I have an email account setup to receive automated tasks. Some of these "alerts" occur too often and they have the same subject line, but different senders. This is the rule I am currently using: ##CODE START## # rule:[AutoAlerts] if anyof ( header :matches "Subject" "AutoAlert Type1*", header :matches "Subject" "AutoAlert Type2*", header :matches "Subject" "AutoAlert Type3*" ) { fileinto "INBOX.AutoAlerts"; stop; } ##CODE END## I was wondering if it's possible to gracefully handle duplicate subjects lines (within a given time frame) with sieve filters ? Ideally, I would like the first email of the day with subject ""AutoAlert Type1..." to get moved to the subfolder given above. Subsequent "duplicate" emails would then go into a "duplicate" subfolder. Is this possible with sieve filters ? I could not find anything striking me as obvious while reading the page http://wiki.dovecot.org/LDA/Sieve. Thanks very much for your input.

[Dovecot] Dovecot failed logins delay all logins
by Dominic Malolepszy 17 Oct '12

17 Oct '12

Hi all, I have observed with my Dovecot setup that unique failed logins cause legitimate correct logins to be slowed. I am running two servers, each with two Dovecot instances, a Proxy with Director, and a backend Dovecot. I suspect that the backend instance is throttling connections from the same IP, and because I am running a Proxy, the backend will only see either of the two server IPs. I confirmed this by directly connecting to the backend, to bypass the proxy and rule it. I initiated dozens of unique failed logins from one IP and separately attempted to login from the same IP, and experienced an extended delay during login. At the same time a login from a different IP suceeded imediately. I see nothing in the logs suggesting some sort of process limits were exceeded, however I do see the following proc title for the backend auth process: "dovecot/auth [7 wait, 0 passdb, 0 userdb]" I have increased the mail_max_userip_connections to a very large value however I believe that setting is a per username/ip limit. Is there any sort of setting in Dovecot that I can configure that stops this authentication throttling per IP? Below is the configuration of the backend Dovecot instance. # 2.1.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.5.2.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.3 (Santiago) auth_cache_negative_ttl = 3 secs auth_cache_size = 100 M auth_cache_ttl = 10 mins auth_default_realm = example.com auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose_passwords = sha1 auth_worker_max_count = 25 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 12 first_valid_uid = 8 last_valid_gid = 12 last_valid_uid = 8 login_greeting = Hello there. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_fsync = always mail_gid = mail mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " stats" mail_uid = mail mmap_disable = yes namespace { inbox = yes location = maildir:%h/Maildir prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocols = pop3 imap service auth { unix_listener auth-userdb { group = mail mode = 0660 user = mail } } service imap-login { inet_listener imap { address = 0.0.0.0 port = 9143 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service imap { process_limit = 1000 vsz_limit = 256 M } service pop3-login { inet_listener pop3 { address = 0.0.0.0 port = 9110 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service pop3 { process_limit = 1000 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = mail } inet_listener { address = 127.0.0.1 port = 24242 } } ssl = no stats_memory_limit = 64 M userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_logout_format = bytes_read=%i bytes_send=%o mail_max_userip_connections = 1000 mail_plugins = " stats " } protocol pop3 { mail_max_userip_connections = 1000 } Dominic

Hi A have a problem with quota2 table, working under postfixadmin.

[Dovecot] Plugin hooks in login process
by Simone Lazzaris 16 Oct '12

16 Oct '12

Hi all; I've setup dovecot (2.1.10) in a cluster configuration. We have two servers acting as frontend which authenticates users and proxy them to other two servers which handles the "real" work. Users credentials are on a mysql cluster; we have one master, in which read/write queries are processed, and many replicated slave, which process read-only queries. The frontend servers reads users credentials from the read-only mysql slaves. I'd like to execute a query once the client is verified to update the last login data. Right now, that query is executed on the backend servers, via a post-login service: protocols = imap service imap-postlogin { executable = script-login /usr/local/etc/dovecot/postlogin.sh unix_listener imap-postlogin { group = vchkpw mode = 0600 user = vpopmail } } service imap { executable = imap imap-postlogin process_limit = 2048 } Problem is, if I execute the update on the backend, I miss the information regarding the original IP, as I only see the IP of the proxies. I haven't been able to launch the postlogin service on the frontend, so I figured that I can try to write a plugin - that also seems to me the cleanest solution. Looking in the dovecot source code, I noticed that there aren't any hooks in the execution path used by the proxies; I am missing something ? I am the only one missing the presence of this hooks in the auth/proxy process ? I've also thought of a workaround for this problem. One way is to monitor the dovecot logs on the frontend and execute the update asyncronously. One other way is to query directly the main mysql server of the cluster and adjust the query making it call a stored procedure that updates the information in case of successful login. But I'd really prefer to create a plugin, that I'd be willing to share. I attach the configuration of the servers (front and back) generated via postfix -n. Thanks in advance for any help. -- Simone Lazzaris | Responsabile aree datacenter e VoIP Interactive Network srl | via Roggia Vignola 9, 24047 Treviglio (BG) Tel. 0363 1970352 | Fax 0363.1971971 | www.interactive.eu

Hi, I have found this strange problem. I'm working with Debian 6, dovecot 2.1.9 and vpopmail-auth. LDA is configured and works fine but the problem is when the first message arrive "dovecot-lda" return a "Segmentation fault", the message is written to the user's Mailbox but the message remains, also, in the queue of qmail (deferral: Segmentation_fault/) and at the second attempt is delivered fine. If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf "Segmentation fault" go away. Moreover, without ACL at the first delivery folders like Sent, Drafts, Trash, Spam appear immediately. An example, new user: root@demo-vpop ~ # tree /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ ├── cur ├── maildirsize ├── new └── tmp root@demo-vpop ~ # cat testmail.txt | /usr/local/dovecot-2.1/libexec/dovecot/deliver -d cecchi2(a)qboxdns.it Segmentation fault root@demo-vpop ~ # echo $? 139 root@demo-vpop ~ # tree

[Dovecot] Search for substring in header?
by Dave Abrahams 16 Oct '12

16 Oct '12

Hi, According to the IMAP spec (http://tools.ietf.org/html/rfc2060#page-37) if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. What am I doing wrong? TIA, Dave -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost
