proxy_maybe & director incompatibility
Hi Folks, I spent quite some time yesterday understanding how proxy works along with the director. I came to the conclusion that proxy_maybe and director cannot be used together, but this isn?t a true incompatibility so much as caused by the way things are handled and the order they are processed in. The way proxy_maybe works is that it is processed by the auth provider once it gets the response from the passdb, it checks for proxy_ma...

CRAM-MD5 and proxy_maybe
When using proxy_maybe CRAM-MD5 authentication fails when the connection is proxied. Is this expected behavior? Is proxy_maybe too simplified for this case? We're using SQL so I could rewrite the query with IFs to fake proxy_maybe and return the password as NULL and nologin as Y, but if it works that way couldn'...

proxy_maybe regex
Does anyone know if dovecot support regex lookups for proxy/proxy_maybe, rather than mysql/ldap etc? I've been comparing it with perdition to see which one might be better for us to do layer7 username switching. Perdition supports the ability to not have any auth/db looks, but rather just a regex file that parses the usernames as they come in and forwards to...

Dovecot Proxy with MySQL auth
We are looking at deploying several pop/imap servers to house the mail for 15,000 or more mailbox accounts. We are contemplating on the design and are looking at using MySQL auth (we already have a MySQL environment in place for our user auth to live) and proxy_maybe so each server can proxy for all the others and we just have a network load balancer distribute the incoming connections to all of the Dovecot servers. Each server would have its own local maildir storage for the users local to that server and all of the authentication and target backend pop/imap...

Trouble with proxy_maybe and auth_default_realm
Hello, I'm using proxy_maybe and auth_default_realm. It seems that when a user logs in without the domain name, relying on auth_default_realm, and the "host" field points to the local server, I get the Proxying loops to itself error. It does work as expected - log on to the local server without proxying, if the...

Hi help is preciated, PROBLEM The dovecot-ldap.conf of "proxy server A" is working when the "host" attribute is the FQDN of other server: pass_attrs = uid=user,userPassword={SSHA}password,\ =proxy_maybe=,maildrop=host,=port=143,=destuser=%u,=starttls=any-cert pass_filter = (&(objectClass=posixAccount)(uid=%u)) CASES When the "host" attribute is the "FQDN of server A" dovecot imap-login start and infinite loop which swallow all RAM, and process are showing many connection...

proxy_maybe and IPv6
Hi, Using dovecot 1.1.2 on a dual-stack server, with the 'proxy_maybe' attribute to forward some clients to another server, it seems that only clients connecting with the same protocol version as the one used by address in the 'host' attribute in the password db are recognized as local. If an IPv4 address is specified as 'host', a dovecot proxy...

custom userdb server, Exim, and proxying
...have Exim using Dovecot for authentication. Dovecot, in turn, consults a custom internal server that answers Dovecot?s userdb queries. When IMAP connections arrive, for some users we want to forward those connections--without authentication--to an external IMAP server. For these users, we return ?proxy_maybe? and ?nopassword? in the authn response from our userdb server. This tells Dovecot to proxy the connection to a new server without trying to authenticate. Exim, though, doesn?t grok ?proxy_maybe?, so it just sees ?nopassword?. In response, it just skips SMTP authentication entirely. We could a...

proxy configuration
...9;s built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect to any server, but their mail files live on one particular machine. I'd like to transparently proxy them from whatever machine they happen to hit to their home machine. Except for the "proxy_maybe" feature advertised for dovecot 1.1, I don't see a surefire way to do this. Has anyone done it, or can anyone say for sure that it can't reasonably be done until "proxy_maybe"? Tx! -- bill-dovecot at carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25...

Proxying improvements in v2.1.2
...this for POP3 as well, although only the remote IP/port is forwarded, not local IP/port. I implemented this also for LMTP in v2.2 tree, but haven't bothered to backport that change. Both POP3 and LMTP uses XCLIENT command that is compatible to Postfix's (XCLIENT ADDR=1.2.3.4 PORT=110). 2. proxy_maybe=yes + host=host.example.com actually works now. As long as host.example.com DNS lookup returns one IP that belongs to the current server the proxying is skipped. 3. auth_proxy_self = 1.2.3.4 setting means that if proxy_maybe=yes and host=1.2.3.4 then Dovecot assumes that this is a local login and...

Userdb's and IMAP proxying
Hello Timo, In order to plan a migration, I want to setup an IMAP proxy (proxy_maybe) with a dovecot server (I'm running the old dovecot-2.1.15 but I could upgrade or use a proxy only dovecot-2.2.x server)/LDAP pass et userdb's. I'm won't be in charge of the migration itself but I think the idea will be to migrate a chunk of users each night and then let the proxy...

proxy and master user
Hi For some application we need a master user on our IMAP servers. We use dovecot 1.1.7 in proxy mode, with proxy_maybe (some mailboxes are on the proxy itself, others are on remote servers, also running dovecot). But the proxy removes the '*master' suffix from the username when using the master user to log in on the proxy. So the base name of the user with the master password are submitted to the real ser...

dovecot director service
hi, we are using the dovecot-rc1 version, and we are testing the director service, as there is little documentation on this service, a pair of questions.. if i'm not wrong, the proxy_maybe it's not implemented, yet? will be soon? this limitation does not allow use the same two directors servers like mail backend servers? the fairlure of one director server it's automatically detected or require manual intervention? thanks and sorry for so many questions...

1.2.15 - segfault if host field attribute not present in ldap. (proxy)
...11.2.so[b7551000+140000] If no host field attribute is present in ldap (like mailHost for qmail-ldap), and we are trying to use proxy, then dovecot segfaults. If more information's needed, let me know. Also, somewhat unrelated, but maybe the wiki needs to be edited since using a template as =proxy_maybe=y works, while in wiki its kinda opposite. I don't know of specifics, but should I try using a recent release ?
