Upgrading dovecot 2.2 to 2.3 without downtime when using proxy/director?
...nt-hashing method is obsoleted. Unfortunately there's no easy way to upgrade directors to use the consistent hashing method without stopping the entire ring. The hard way would be to build a secondary director ring and start moving users to that ring in proxies. Added https://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy#moving <https://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy#moving> to explain further the hard way. -------------- next part -------------- An HTML attachment was scrubbed...

Dovecot proxy/director and mail pop3/imap backend service on same server
...default imap/pop3 ports? Using the default ports will clearly cause loops. Can anyone kindly provide an example snippet of config that tells the director to use different port for IMAP and POP3 proxy? I have so far found the following pages helpful to what I am working on: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy http://wiki2.dovecot.org/PasswordDatabase/ExtraFields http://wiki2.dovecot.org/Director Cheers, Aerion.

Denying authentication
Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can

patch: allow proxy to lookup host by name
...expected to work against 1.2.11. The patch is pretty straightforward, it's making it work within the restrictions of the login process that's more interesting. I have made some changes to the wiki (pending approval) to - enhance the discussion of proxy with LDAP http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy - discuss the implication of this patch w.r.t. the login_chroot configuration parameter: http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy/HostLookup Feedback is appreciated, particulary from a security standpoint.

passdb evaluation order
Hello, I could have several password databases in dovecot. And according to http://wiki.dovecot.org/PasswordDatabase these passwdbs could allow or deny users and they could have different result_failure and result_sucess behaviors. So the order in which they are evaluated may be significant. So, how do I define this order? -- Angel L. Mateo Mart?nez Secci?n de Telem?tica ?rea de Tecnolog?as de la Informaci...

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 movin...

Dovecot Proxy with MySQL auth
...wn local maildir storage for the users local to that server and all of the authentication and target backend pop/imap server data would be stored in the same MySQL database. The problem we are running into is the documentation is not very clear on this type of scenario. http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy At the bottom of this page it gives a query example of "SELECT NULL AS password, ." but that does not seem to allow for us to use the proxy_maybe if the destination server is localhost (and therefore do not proxy) it does not seem that the above query will actually s...

Dovecot LMTP Proxy + STARTTLS?
Hi I got dovecot 2.2.26 on a Centos7 with latest updates. Dovecot is configured to act as director and delivers to my two backend servers. I enabled lmtp proxy on director to listen on port 24. Now I see in msg headers that the connection to the lmtp proxy uses STARTTLS but the connection from proxy to backend seems to be unencrypted. Is it possible to enforce the use of STARTTLS in the

Imap proxy with tls?
...working (call that the remote server). Now I want to have a few computers at the same place to access the same account on the remote server. I have another server (call this the local server) at the local site to do this with but am not sure how to do it. The proxy setup http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy looks about right but that does not seem to support tls? I need tls going from the local server to the remote server. I want all emails on the remote server to be the same as on the local server. This way all clients at the local site have very fast access to email and can stil...
