Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with the great Dovecot. SOGo webmail is connected to the proxy and works great (very very more fast) but I have a problem with Thunderbird : mailbox with ? SPECIAL USE ? aren't automatically detected. To make that works, I must : - in Dovecot : define the namespace inbox : ? prefix = ? and ? separator = . ? - in

Hi, We are building a new system that will support a large number of users (high volume, high concurrent usage, etc).? We have played with Dovecot, but in most serious applications we have traditionally used Courier IMAP.? It's my (lay) understanding that with indexing and perhaps other things in Dovecot, it might perform better than Courier in larger environments like this.? Am I correct or

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 created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no

Hello, we are working in the migration from courier-imap to dovecot 2.2.10-4.el7_0.1.x86_64. Some emails that send a internal application show as sender "MISSING_MAILBOX at missing_domain", i use like email client Horde using dovecot like server. But if i open that email with Horde and courier-imap i can see the correct email sender. I think that the email of the sender is no correct

Hi We've been using dovecot with great success so far. We are trying to add sieve support for our users. We enabled managesieve and users can define rules from the webmail (roundcube) with sieverules plugin for roundcube. Everything goes ok, but here's a problem I couldn't figure yet. When I define a redirect rule, the mail is forwarded but a local copy is stored too. Weird thing is

Good day, I am currently setting up/debugging a webmailer-only setup using Roundcube (latest version) with Dovecot (2.3.20, latest as of now). Generally speaking the setup performs OK, I wrote a JMeter Roundcube script to test the Roundcube. This includes actions like listing mails and fetching them. I am hitting a somehow dubious limit of 600 req/s though. (This includes all kinds of HTTP calls

Timo, Is the director proxy inactivity timeout configurable? I just recently attempted to switch our production webmail's imapproxy system to use a pool of two directors and ran into problems with it apparently disconnecting them unexpectedly. I don't believe that it IDLEs, I think it just UNSELECTs to reset the state and then keeps the connection open until it's used again, or until

Good day. I have a dovecot 2.3.4.1 on debian 10 as an imap server. I found there are emails where the header field From has no encoding even if there is a name with special characters like ?lut? K??. The header looks like: From: "?lut? K??" <zluty.kun at domain.tld> In this case the email client - roundcube, outlook etc. will show the From with wrong characters. This behaviour is

Hi, I'm testing/using dovecot as imap proxy, passdb/userdb as passwd-like-file. It seems to function as expected (1). This setup is described in the wiki in AuthSpecials. But I also noticed in the documentation (ImapProxy / FeatLoginProxy pages) that the proxy feature only works with a sql passdb. Maybe I did something strange, but passwd-like-passdb does work..... So I have some

Hello, i using roundcube with dovecot, i have a question if there is possible to know the number of users that using the mail system (in other word the online users) . thanks, best regards, ihab :) -- View this message in context: http://dovecot.2317879.n4.nabble.com/number-of-users-tp48701.html Sent from the Dovecot mailing list archive at Nabble.com.

Greetings everyone, I'm new to the list as of today. I just installed Dovecot a couple of days ago for the first time, Debian Lenny Dovecot v1.0.15-2.3. So far I'm pretty impressed. I'm using mbox format with Dovecot auto-deciding to place mail in user home directories, which is great. It works very well with the Win32 Thunderbird 3 client over a small basic 100FDX switched net.

hello list, I am attempting to sync two imap servers using the imapsync perl script. It seems handy and easy. Here's what happens when I try to do this: # # Postfix master process configuration file. For details on the format # of the file, see the master(5) manual page (command: "man 5 master"). # -o smtpd_sasl_auth_enable=yes # -o

unfortunately im not authorized to publish the whole headers and content, but as an example: in headers: To: ""Ing. Mark?ta Kleinov?"' <x at xxx.xx> view in the webmail or outlook "Ing. Mark??ta Kleinov??" <mailto:kleinova at pkvp.cz> and it should be Ing. Mark?ta Kleinov? The problem is with From and To headers. > 23. 6. 2020 v 10:43, Aki Tuomi

Hello list. I'm planning a new mail servers for our company's customers to replace the oldish Courier-IMAP based one, we already started to deploy some mail accounts on a dovecot-2.0 server as an early test. I'd like to implement the new system with dovecot-2 (I'll probably go straight to dovecot-2.1.x) and I'd like to get it right from the beginning so I'm here asking for

Hi, I have two load-balanced dovecot servers using a single NFS mount. The version is 1.2.11. I chose this so that if one server goes down the other will take up the load, and if my load is too much for one server I just have to add more identical servers. It works, but I wish to move to SAN storage because the NFS server is exhibiting irregular performance. (I spent a lot of time with tcpdump to

Hi all, Is there a function to modify the fetch order of messages? We have just migrated from Courier to Dovecot and I notice that there is a slight difference in the way messages are fetched in Dovecot compared to Courier. Both Courier and Dovecot sort the mailbox correctly (UID SORT (REVERSE ARRIVAL) UTF-8 ALL), for example: [ 13:22:02.790 ]50800314 UID SORT (REVERSE ARRIVAL) UTF-8 ALL * SORT
