It seems we have a few email addresses that are not RFC 5322 compliant, and now that we've started using sieve these are failing. The problem is that we have a few addresses with leading, trailing or double dots in the local part: jan..frode at tanso.net .janfrode at tanso.net janfrode. at tanso.net I believe these has been working fine with everything else in dovecot (lda, lmtp, imap, pop), but that sieve is more strict. I think it's fair enough that it's strict with messages generated by sieve scripts, but it would be nice if it co...

I now have "mail_home = /srv/mailstore/%256RHu/%d/%n". Is there any way of asking dovecot where a user's home directory is? It's not in "doveadm user": $ doveadm user -f home janfrode at lyse.net $ doveadm user janfrode at tanso.net userdb: janfrode at tanso.net mail : mdbox:~/mdbox quota_rule: *:storage=1048576 Alternatively, is there an easy way to calculate the %256RHu hash ? -jf

Hi This is my first post here so i will be as precise as i can I'm trying to setup a quota system using dovecot postfix and procmail dovecot version 1.2.9 postfix version 2.7.0 I have succesfully modified dovecot config to use fs quota system (so far imap and pop3) It reports correct quotas to imap and pop3 clients (both user and group) What im tryin to do now is to modify

We've been collecting some stats to see what kind of benefits UP/SquirrelMail's IMAP Proxy in for our SOGo webmail users. Dovecot is running in High-performance mode http://wiki2.dovecot.org/LoginProcess with authentication caching http://wiki2.dovecot.org/Authentication/Caching During the weekend two servers (webmail3 and webmail4) has been running with local imapproxy and two servers

I'm preparing to set up a new set of directors on dovecot-ee-2.1.10.3-1, but would prefer to do this a bit gradually. Will it be OK to set up a ring of directors with 2x dovecot-ee-2.1.10.3-1 and 2x dovecot-2.0.14 ? -jf

I'd like to get the IP-address of the webmail-klient logged in my maillog (for being compliant with coming data retention policies). I've noticed that with login_trusted_networks pointing at my dovecot directors, we get rip=client-ip logged on the backends. How is the proxy providing this to the dovecot backends? Anybody know what magic we need to implement in our webmail-solution to be

We upgraded our two dovecot directors from v2.0.14 to dovecot-ee 2.1.10.3 this week, and after that mail seems to be flowing a lot slower than before. The backend mailstores are untouched, on v2.0.14 still. After the upgrade we've been hitting process_limit for lmtp a lot, and we're struggeling with large queues in the incoming mailservers that are using LMTP virtual transport towards our

I need to migrate 15K users to a new domain name, and plan to use "dsync mirror" in the transition phase. Could someone confirm that this should work: Before giving users access to new-domain do a first sync to get all the stale data over: for user in $old-domain; do dsync mirror $user at old-domain $user at new-domain done Configure sieve vacation filter to forward all messages

...caching the result, and present old values if the directory timestamps hasn?t changed). I think this checking of unread messages webservice would be much nicer on the filesystem if it instead used the dovecot indexes, so I created a small utility based on utils/idxview.c that do that: http://blag.tanso.net/code/unread.c But this woun?t work if the maildir has been modified outside of dovecot (i.e. webmail usage). Are there any simple interface I can use in this short snippet for noticing that the index is out of sync, and update it ? -jf

I'm in the processes of running our first dsync backup of all users (from maildir to mdbox on remote server), and one problem I'm hitting that dsync will work fine on first run for some users, and then reliably fail whenever I try a new run: $ sudo dsync -u janfrode at example.net backup ssh -q mailbackup at repo1.example.net dsync -u janfrode at example.net $ sudo dsync -u janfrode

Hello, Following Jan-Frode's advise I am trying this configuration: {postfix} ---lmtp---> {director} ---lmtp---> {dovecot} so I have two dovecot instances for director/proxy and lmtp delivery on ports 1024 and 24 respectively. whilst for imap connections I can specify a pool of imap backend servers via 'director_mail_servers' it seems is not possible with lmtp.

Great information, thank you. Could you remark on GPFS services hosting mail storage over a WAN between two geographically separated data centers? ----- Reply message ----- From: "Jan-Frode Myklebust" <janfrode at tanso.net> To: "Stan Hoeppner" <stan at hardwarefreak.com> Cc: "Timo Sirainen" <tss at iki.fi>, <dovecot at dovecot.org> Subject: [Dovecot] GPFS for mail-storage (Was: Re: Compressing existing maildirs) Date: Tue, Jan 3, 2012 2:14 am On Sat, Dec 31, 2011 at 01:5...

Hi Everyone, I wish to create a Postfix/Dovecot active-active cluster (each node will run Postfix *and* Dovecot), which will obviously have to use central storage. I'm looking for ideas to see what's the best out there. All of this will be running on multiple Xen hosts, however I don't think that matters as long as I make sure that the cluster nodes are on different physical

Currently if user is 1MB under quota and someone tries to deliver mail that is over 1MB, Dovecot rejects the mail. But smaller mails aren't rejected probably for days. So user might not even realize that they didn't receive one of the mails. Also having a user "almost over quota" is a rather strange state I think. So what do you think about v2.2 allowing delivery of one last

I'm considering putting two servers with failover IP-addresses in front of our pop/imap cluster, with dovecot in proxy-mode running on both servers. But, can dovecot handle more than one backend server for each user ? I.e. I would want to point the dovecot proxy to send userX to backend-server1, or backend-server2 if backend-server1 is down. Is something like that possible ? -jf

We're looking at replacing our mysql auth and userdb, with a set of Red Hat Directory servers, and I see dovecot supports either authentication binds, or "password lookups": http://wiki.dovecot.org/AuthDatabase/LDAP I'm curious if anybody can give any insight as to what kind of performance to expect from authentication binds ? How many POP3s/second should we expect from it

I plan on putting two dovecot directors in front of our backend dovecot pop/imap servers, instead of our current haproxy loadbalancing of the connections -- but how do we handle SSL in such a setup. Will all SSL be terminated on the directors automatically, and then proxyed plain text, or is there any configuration needed to achieve this ? Does it matter that the directors are v2.0 while the

Some filesystems are quite slow at deleting files, so I'm wondering if anybody is using the lazy expunge plugin to implement a solution where expunged messages are moved to a separate directory structure within the same filesystem, and later deleted as a nighly batchjob ? Assuming expunge renames/moves messages, and don't do a copy + delete.. Does something like this make sense ? -jf
