dovecot proxy, imapproxy, perdition . . . or?
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

Complete migration from Cyrus on remote server
Hi All! I am working on a complete migration from an old solaris machine running Cyrus IMAP v2.3.14 and wish to migrate all users to a new ubuntu vm running Dovecot 2.0.19. What I have so far is a fully functional dovecot installation with LDAP / Dovecot SASL auth using Maildir++. My plan is to use Perdition IMAP proxy on a third host and migrate users a few at a time (see attached picture of

securing dovecot proxy connections
The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the

IMAP/POP3 server with proxy feature
We are currently evaluating the migration from a proprietary, legacy mail server onto Dovecot for 20,000+ virtual domains. This is a big job and we intend to do it by initially proxying connections through to the legacy server, and moving customers over in batches by turning off the proxy feature for them. In the manual it states "This model is still a bit unfinished in current code"

Director proxy timeout
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

Slow DNS warnings (proxy/auth)
Hello, I've just finished transiting our proxies from perdition to dovecot (2.1.7-7 Debian). Yesterday 12 messages (all within the same second) like this caught my attention: --- Apr 25 17:19:09 pp11 dovecot: auth: Warning: proxy(redacted at gol.com,xx.xx.xx.xx,<26hUEivbfQBlMrMS>): DNS lookup for mb04.dentaku.gol.com took 5.002 s --- Now this machine at that time was handling a load

IMAP-proxy or not with sogo webmail and dovecot backend
We've been collecting some stats to see what kind of benefits UP/SquirrelMail's IMAP Proxy in for our SOGo webmail users.

proxy configuration
Before I spend some time experimenting with what might be impossible, maybe someone can just tell me (either "how" or that it's impossible). I'd like to get perdition out of my environment (mainly to have one less moving part in my architecture). I'm looking at dovecot's built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect

weird situation with pop3/imap proxy and postfix authentication
Hello dovecot mailing list, I have a server running postfix and dovecot. I havea configuration on dovecot that allows me to provide imap4/pop3 messages for local hosted users as well as for proxied users on other servers. Basically, i have a simple MySQL table (imapproxy) with two fields, 'domain' and 'host'. My password_query isa 'UNION' query, exactly like:

Proxy to more Servers
Hi list! Finally I got the LDAP-Authentication work (it was a problem of the OU-Path... :( ). Now I can authenticate the user against the AD and forwarding the IMAP-Connection to the Exchange Server. Wow! My next problem: we have TWO ADs and TWO Exchange-Servers. The first AD has the users for the first Exchange, and the second AD for the second Exchange. I defined two files so:

Does Director only work with dovecot proxy?
I was reading "conf.d/10-director.conf" and it mentions Dovecot proxy. I've been using perdition in the past for my pop/imap proxying needs and wasn't sure if Director could also use perdition or if it only works with Dovecots proxying. Thanks!

Roundcube <-> Dovecot timeouts under very moderate load on big Dovecot nodes
Due to a recent topic regarding the performance of the Roundcube webmailer with Dovecot as a backend, I set up imapproxy successfully, shrinking the response latency of the webmailer heavily, which is great. However, I still encounter strange timeouts on some requests when Roundcube tries to access Dovecot. Be it for authentication or to FETCH data. I run the tests/benchmarks via distributed
