[Dovecot] replication chain
by Костырев Александр Алексеевич 08 Aug '12

08 Aug '12

good day! I wonder if it is possible to make a chain of replication in dovecot 2.1.9. Now I'm using two way replication(I use proxy to redirect users) and it's working just fine but is it possible to setup replication like this: serverA ---> serverB --> server C <--- I've added additional mail_replica2 on serverB and after restart dovecot didn't complain about errors, with doveconf -n I am able to see two replica's settings but user's mails aren't replicating to server C. no errors in logs. I want to use server C as backup server with lvm snapshots.

Do the same user(s) have this problem and/or do each user have their own mail configuration for their mail readers? If yes, I would also check that the port and security protocol matches (i.e. clear/TLS/SSL on ports 110/110/995 respectively). Mismatched configurations could cause what you describe. Log messages could also be helpful here. Joseph Tam <jtam.home(a)gmail.com>

Re: [Dovecot] redirect actions exceeds policy limit
by Mike Greene 07 Aug '12

Thank you David, I saw that in the share/docs but we didn't have the /conf.d/ folder or any of the extra conf files in place. I created that directory, copied the file over, made my changes and all is well again. Not sure why things were setup the way they were, after looking at the other files in conf.d it would appear the previous sysadmin had merged a lot of those bits and pieces into the main dovecot.conf file. Perhaps leftovers from v1.x days. Will likely address that down the road when we update that server. Mike Greene Rock Island Technology Solutions, Inc.

[Dovecot] Pigeonhole sieve include namespace regression
by Daniel Piddock 07 Aug '12

07 Aug '12

Hi, We've recently upgraded from Dovecot 1.2.15 with Sieve 0.1.18 (Debian Squeeze) to Dovecot 2.1.8 and Pigeonhole 0.3.1. We provide a selection of global sieve scripts to make users' lives easier and one noticed that some of these have stopped working. I tracked it down to them having personal scripts with the same name. Using a really simple sieve script: require "include"; include :personal "svn"; include :global "svn"; sievec debug output for sieve 0.1.18 (trimmed a bit): * Required extensions: 0: include (16) 1: fileinto (5) * Included personal script 'svn' (block: 3): [script code here] * Included global script 'svn' (block: 4): [script code here] * Main program (block: 1): 00000000: EXTENSIONS [1]: 00000001: include 00000002: INCLUDE: 00000004: script: svn.sieve [ID: 1, BLOCK: 3] 00000006: INCLUDE: 00000008: script: svn.sieve [ID: 2, BLOCK: 4] 0000000a: [End of code] sievec debug output for Pigeonhole 0.3.1: * Required extensions (block: 1): 0: include (id: 16; block: 4) 1: fileinto (id: 5) * Included personal script 'svn' (block: 5): [script code here] * Main program (block: 2): Address Line Code 00000000: DEBUG BLOCK: 3 00000001: EXTENSIONS [1]: 00000002: include 00000003: 2: INCLUDE: 00000005: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 00000007: 3: INCLUDE: 00000009: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 0000000b: 3: [End of code] As can be seen the personal script is included twice. Obvious work around is to rename the personal script. However it'd be nice if namespacing came back.

[Dovecot] connectionlimit for pop3s?
by Hajo Locke 07 Aug '12

07 Aug '12

Hello, i have a user who is able to do pop3 on port 110 without problems and without limits. There are ~10 real users using same public IP. When switching to port 995 to use pop3s he is limited at connection count. Some people can reach pop3s-server successful, some getting a timeout. I cant find any errors or limits within my config or in my log, there are no differences between using plain text and using tls. Are there some special loglines to grep for at this situation? Maybe i missed some lines... At the moment i dont see server-side problems. Somebody knows some typical clientside problems when this problem occurs? dovecot version is 1.2.11 Thanks, Hajo

[Dovecot] redirect actions exceeds policy limit
by Mike Greene 06 Aug '12

06 Aug '12

Hello, We have a vacation/mail forwarder plugin in squirrel mail that allows customers to forward email. It has come to my attention that there is a limit (appears to be 5) on the number of addresses that can be specified. I'm now trying to track down where this policy limit is set. This is the error we see in the customers .dovecot.sieve.log file: main_script: line 26: error: number of redirect actions exceeds policy limit. sieve: info: started log at Jul 25 07:02:54. I checked the following for possible settings: /usr/local/etc/dovecot/dovecot.conf /usr/local/etc/sieve/dovecot.sieve /usr/local/etc/sieve/global.sieve I didn't see anything specific to limiting the number of redirects. I'm wondering where else I can look to find where this limit is coming from and adjust it upwards. We are using the following dovecot / pigeonhole versions. dovecot-2.0.7 dovecot-pigeonhole-0.2.1 athena# dovecot -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.1-RELEASE amd64 auth_default_realm = rockisland.com auth_mechanisms = plain login cram-md5 auth_username_format = %Lu disable_plaintext_auth = no dotlock_use_excl = yes first_valid_gid = 1000 first_valid_uid = 1000 listen = * mail_location = mbox:~/mail:INBOX=/var/mail/%u 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 passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { quota = maildir quota_rule = *:storage=2G quota_warning = storage=90%% /usr/local/sbin/quota-warning.sh 90 quota_warning2 = storage=80%% /usr/local/sbin/quota-warning.sh 80 sieve = ~/.dovecot.sieve sieve_dir = ~/ sieve_global_dir = /usr/local/etc/sieve/ } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { group = vmail mode = 0600 user = vmail } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service imap-login { service_count = 0 } service pop3-login { service_count = 0 } ssl_cert = </usr/local/etc/ssl/star.rockisland.com.crt.pem ssl_key = </usr/local/etc/ssl/star.rockisland.com.key.pem userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = lda_mailbox_autocreate = no lda_mailbox_autosubscribe = yes log_path = mail_plugins = quota sieve postmaster_address = postmaster(a)rockisland.com sendmail_path = /usr/sbin/sendmail } Mike Greene Rock Island Technology Solutions, Inc.
