[Dovecot] mdbox
by Daniel L. Miller 25 Sep '10

25 Sep '10

Reviewing some mailing list archives and the wiki, I still don't have a real clear picture of why I'd want to use mdbox. What I've taken from the info I've reviewed says mdbox is more complicated (than sdbox), has greater potential for breakage (simply because it's more complex), and has a theoretical performance impact depending on the exact filesystem/hardware used. Was that an accurate summary? Is mdbox something that was desired to solve a particular problem? -- Daniel

You > didn't really give enough information about what user you're running > doveadm as or if you're using system or virtual users or.. Sorry. I'm running that doveadm command as root, with the -u <user> parameter, where <user> is a virtual user. Anyway, I've just read the wiki2 again, and noted that I don't really need the expire plugin, because it is only needed for the -A option. If I specify the -u parameter, it doesn't utilize the plugin. So I'm now using only the doveadm expunge -u ... command, which now gives me this output: # /usr/local/bin/doveadm -D expunge -u <user> mailbox sa.* SAVEDBEFORE 1d doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object ^^^ I'm curious about this error message.

[Dovecot] LDA + Postfix + LDAP + Sieve (Vacation): Wrong Domain in Reply
by Kendall Gifford 24 Sep '10

24 Sep '10

Hello everyone. I'm running dovecot (1.2.9) with postfix (2.7.0) on an ubuntu 10.04.1. I'm hosting mail for several domains and using the dovecot local delivery agent. Everything has been working great. However, today I set up a sieve script to send out-of-office replies (vacation) for one of our users. I tested it and got the response just fine. However, when looking at the "From" header of the auto-reply, I noticed that the domain name was wrong. My postfix master.cf line for doing local delivery is: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} My LDA configuration is: protocol lda { postmaster_address = postmaster(a)our-primary-domain.com hostname = our-primary-domain.com mail_plugins = sieve quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } So, our main "administrative" domain is: my-primary-domain.com, the mail server being mail.my-primary-domain.com. I sent an email to a user: janedoe(a)my-other-domain.com and the LDA with Sieve successfully sent me a reply. However, the "From" was: janedoe@mail instead of janedoe@my-other-domain. According to: http://wiki.dovecot.org/LDA/Sieve#Vacation_auto-reply > Vacation uses envelope sender and envelope recipient ... taken from: > ... > V 1.1+ > ... > Envelope recipient: -a parameter to deliver if given, otherwise -d parameter to deliver. If neither is given (delivering to system users), the $USER environment is used. Just for kicks I tried changing my master.cf to use -a instead of -d but then all mail delivers to user "mail" completely breaking all mail delivery. Anyhow, vacation auto-responders are fundamental to operations here and we manage mail for several separate companies. We need the "From" address to reflect the domain of the actual company. I'm stumped as to why sieve isn't getting/using the envelope sender's domain. I'm hoping someone here can point out (a hopefully obvious) mistake. I've attached my four pertinent config files as etc.tgz only slightly scrubbed. Any help is greatly appreciated. -- Kendall Gifford zettabyte(a)gmail.com

[Dovecot] Trouble creating shared virtual folders
by Daniela Silva 24 Sep '10

24 Sep '10

Hi all, I've tried to contact Timo Sirainen by dovecot irc channel but since I couldn't I'm trying the mailinglist. I'm trying to create shared virtual folders, users should not be able either to create or delete a virtual folder. What is the best way to do this? I've tried to do this with virtual mailboxes, but I had problems with permissions, I removed write permissions from folder "virtual_folders" but if I do that dovecot creates "virtual_folders_indexes" without write permissions too, which in this case are needed. I've tried to solve this using ACL but as far as I understood I need an ACL file per folder, which in my case is undoable.

[Dovecot] Unsubscribing from public folders
by aditsu 24 Sep '10

24 Sep '10

Hi, I'm having problems unsubscribing from public folders - nothing seems to happen when I do that (from Thunderbird, Squirrelmail or telnet). I'm using Dovecot 1.2.11. I remember that this worked when I was using version 1.1.7. Here is an extract from an imap session: 3 unsubscribe "Public-NIB/archive/older" 3 OK Unsubscribe completed. 6 lsub "" "Public-NIB/*" * LSUB () "/" "Public-NIB/archive" * LSUB () "/" "Public-NIB/archive/2008b" * LSUB () "/" "Public-NIB/archive/2009a" * LSUB () "/" "Public-NIB/archive/2009b" * LSUB () "/" "Public-NIB/archive/older" * LSUB () "/" "Public-NIB/archive/2010a" 6 OK Lsub completed. And my relevant config: namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace public { separator = / prefix = Public-NIB/ location = maildir:/(some path) subscriptions = no # v1.1+ } In the meantime I checked and found a "subscriptions" file in my maildir, then went and edited it by hand (and removed the folder I wanted). That seemed to work, and afterwards I can subscribe/unsubscribe to that particular folder, but still not to any other public folders. What could be the problem, or how can I debug this? Thanks Adrian -- View this message in context: http://old.nabble.com/Unsubscribing-from-public-folders-tp29779347p29779347… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Possible to split message store location?
by Edward Carraro 24 Sep '10

24 Sep '10

We have a few dovecot servers all pointing to the same mail location (an NFS mount on a NAS drive). This could lead to a possible bottleneck eventually and we were wondering if it's possible to have dovecot direct x number of users to one message store location while others get their mail on a different mount?

[Dovecot] Dovecot pop3 segfault problems

Hi to all, I have a Debian 4.0 x86_64 server and installed Dovecot from the repositories ii dovecot-common 1.0.rc15-2etch5 ii dovecot-imapd 1.0.rc15-2etch5 ii dovecot-pop3d 1.0.rc15-2etch5 Recently I'm getting a lot of these messages pop3[24594]: segfault at 0000000000000004 rip 000000000044333a rsp 00007fffc5d0c1e0 error 4 in syslog and also dmesg. Also the load of the servers keeps increasing (like above 100) and when dovecot is stopped the load decreases. What problem could this be and how can I resolve it? Thanks, Enid

[Dovecot] dovecot+sieve redirect action signal 11 while user homedir not defined
by Maciej Uhlig 24 Sep '10

24 Sep '10

Hi, while executing simple sieve script: require ["fileinto", "envelope"]; if header :contains "subject" "test" { redirect "user@domain"; } we got: 2010-09-23T09:25:23+02:00 st1/192.168.10.201 dovecot: [ID 583609 mail.error] master: Error: service(lmtp): child 15524 killed with signal 11 (core not dumped) in case user home directory is (erroneously) undefined. This happens with 'redirect' action only ('keep', 'fileinto' work ok). Moreover, since there is no homedir, there is no core file too :-) After user homedir was defined, the error disappeared. This is under Solaris 10 with dovecot 2.0.3 and pigeonhole 0.2.0. Thank you, Maciej Uhlig

[Dovecot] Setting hierarchy separator
by ksrini9＠yahoo.com 24 Sep '10

I am trying to convert my maildir mail store to dbox using dsync (using "dsync -u username convert dbox:/mailstore2/dbox"). I get the following error message: dsync(root): Fatal: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace). My problem is that I do not know how to set separator in 10-mail.conf. I would appreciate any pointers.
