[Dovecot] recipient_delimiter -- feature request
by Andrew Ray 29 Jan '14

29 Jan '14

Hi, It would be nice if the recipient_delimiter configuration option supported multiple recipient delimiters as Postfix now does. e.g. now if I set: recipient_delimiter = +- in Postfix, then test-extension(a)sample.com and test+extension(a)sample.com are both recognized. But if I set: recipient_delimiter = +- in Dovecot, neither of the above are recognized and instead test+-extension(a)sample.com is valid. Well, presently this feature isn't that important to me, but I imagine it could be a source of confusion for people who are migrating from say qmail to postfix (as I am doing) and notice Postfix's cool ability to support both types of delimiters and assume Dovecot will as well (as I did). Thanks, Andrew Ray -- Andrew Ray +1 404-418-5443 +421 (0) 917 832 253 http://guns.freedomlives.net/

[Dovecot] post-login scripting failing with "denied access to user" v2.1.7
by Frank 29 Jan '14

29 Jan '14

I am trying to have a default sieve rule for new mailboxes that can be edited by users using the round cube sieve plugin. It would actually be better executed when a new user is created but my postfixadmin runs on a separate machine so that's a bit tricky. The "sieve-default =" setting won't quite achieve what I want as I want users to be able to edit the default rule (to adjust SPAM level) Mail works fine before I add my post-login script to 10-master.conf ---------------------- service imap { # tell imap to do post-login lookup using a socket called "imap-postlogin" executable = imap imap-postlogin } service imap-postlogin { # all post-login scripts are executed via script-login binary executable = script-login /etc/dovecot/custom_sieve/postlogin.sh # the script process runs as the user specified here (v2.0.14+): user = mail # also tried $default_internal_user and root # this UNIX socket listener must use the same name as given to imap executable unix_listener imap-postlogin { } } After adding this setting, login fails and gives the error below. It certainly looks like a permission issue, but I have checked my script is executable and owned by vmail:vmail. The bash script executes fine as the mail user. The other possibility is that dovecot is denying access to the $HOME variable, but that seems unlikely. Nevertheless, I am stuck!

Just a guess, but I expect the difference is because NetApp de-dupes by checksumming blocks and mark whole blocks as duplicates if they have the same checksum. The message body has the same block offset in maildir (i.e. the start of a message is at byte 0), whereas mdbox might align message body anywhere in a block, so you might have 512 different block configurations for the same message. I don't know whether message alignment would be a worthwhile optimization for mdbox. Joseph Tam <jtam.home(a)gmail.com>

Everything costs less than a NetApp...except an EMC. > If anyone has any first-hand experience (or even > off-the-top-of-their-head thoughts), I'd love to hear them) Distributed filesystems give you the advantage of a single filesystem namespace with massive amounts of storage, fairly easy addition of storage space, and distributed replication to allow failure of a storage node without service interruption. Replication mitigates node failure, but not disk failure, so you still need RAID in each node. So you have RAID6 in a node and filesystem block mirroring amongst nodes. Thus storage utilization is -worse- than direct attach, CFS on SAN, or NFS head attached RAID10 and far worse than RAID6 in these 3 setups. And if using large SSD cache you'd surely use RAID6 with DAS, CFS, or NFS. You'd need half as many disk drives vs DFS. Each DFS expansion, assuming the typical model, entails the cost of a server, RAID HBA (unless using md) and disks, not strictly buying disks as with DAS, CFS/SAN, or NFS filer. Then you also need more switch ports, more power connections, greater UPS capacity due to all the CPUs, RAM, etc in the nodes. And you'll have a higher electric bill. So while a distributed filesystem storage architecture may seem less expensive it may not be. And just as one can build a DIY DFS cluster, one can also build a DIY NFS cluster instead of buying a NetApp, saving significant cash on the front end box and on disks since you'd need half as many vs a distributed filesystem architecture, though failure of one node may not be quite as graceful as with a NetApp losing a controller board. -- Stan

[Dovecot] Replication - what am I doing wrong?
by IT geek 31 27 Jan '14

27 Jan '14

Hi, I'm having issues getting replication working, and I'm not also not having much luck finding help on it. So I'm wondering... am I not asking the right questions? Or am I not providing enough information... or do we just not know how this aspect of the technology works? If it's the former, then any pointers on what questions to ask or information to provide would be very helpful. If the community genuinely doesn't know how this works then that's okay too - I will look at another solution (if one exists) and try to move on. But if I can get this working then that would be amazing as I really like Dovecot and would be gutted to move away from it. -Mark

[Dovecot] managesieve - point me in the right direction?
by erik 27 Jan '14

27 Jan '14

Hi, I am using Dovecot 2.1.16. I'm trying to get Roundcube to talk to the managesieve plugin. Postfix/Dovecot/Roundcube all exist on the same server. I'd like to get managesieve working. I've gone through a few guides, such as: https://wiki.archlinux.org/index.php/dovecot#Sieve But so far roundcube won't connect to the managesieve plugin. ("Cant reach server"). I see that port 4190 is listening and I can telnet to that port: Connected to localhost. Escape character is '^]'. "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave" "NOTIFY" "mailto" "SASL" "PLAIN LOGIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." I'm not sure what else to check. Any help appreciated!

[Dovecot] outlook will not sync
by Eric Broch 27 Jan '14

Dovecot users list, I started having problems with Outlook not syncing with Dovecot a public imap folder upon issuing a send/receive in the client; eventually Outlook timed out, and I received the following error in the Dovecot log. Jan 23 09:20:23 imap(user(a)mydom.com): Error: FETCH [] for mailbox projects.myfolder UID 120 got too little data: 7744 vs 7759 Jan 23 09:20:23 imap(user(a)mydom.com): Error: Maildir filename has wrong W value: /home/vpopmail/domains/mydom.com/shared/projects/.myfolder/cur/1384292337.M440452P9788.mail.mydom.com,S=265901,W=269597:2,Sc Jan 23 09:20:23 imap(user(a)mydom.com): Error: Corrupted index cache file /home/vpopmail/domains/mydom.com/shared/projects/.myfolder/dovecot.index.cache: Broken virtual size for mail UID 120 Jan 23 09:20:23 imap(user@mydom): Info: Disconnected: FETCH failed bytes=175/270387 However, I've since removed the file manually, deleted the old folder and recreated it and Outlook will still not sync even in the absence of the above error.

by Chris 26 Jan '14

26 Jan '14

Dear All, I'm using version 2.1.7 which currently ships with debian stable. I'd like to use userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail override_fields = skip = never result_failure = continue result_internalfail = continue result_success = return-ok } from [1]. The error message is: Jan 25 14:02:03 post1 dovecot: lda(chris): Error: user chris: Initialization failed: Namespace '': stat(/home/vmail/chris/Maildir) failed: Permission denied (euid=1000(chris) egid=1000(chris) missing +x perm: /home/vmail/chris, dir owned by 1001:1001 mode=0700) The skip and result_* commands aren't supported. My users file: chris:{MD5-CRYPT}$1$3uC3URg......:::/home/vmail/chris/:/bin/false:: Dovecot should access the Maildir with vmail:vmail (1001:1001) and not chris:chris (1000:1000)! Thank you in advance! - Chris [1] http://wiki2.dovecot.org/UserDatabase
