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't it work with proxy_maybe?
This works:
password_query = \

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 user does include the domain name in the login.

Ignored proxy_maybe var and no local login when "host = Proxy FQDN"

The dovecot-ldap.conf of "proxy server A" is working when the "host"

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 is created
for clients

destuser setting useless on LMTP proxy
I tried setting the "destuser" setting on the LMTP director as follows, to preserve the original envelope rcpt:
protocol lmtp {
auth_socket_path = director-userdb
passdb {
driver = ...
override_fields = destuser=%{orig_user}
}
}
The passdb driver would return the appropriate "user" for each alias. Suppose, for example, user1 has emails user1 at domain.tld,

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

Recipient delimiter and lmtp proxying
Hi,
I'm attempting to proxy lmtp using director to hash to the same backend
as pop3/imap. My pop3/imap users are of the form:
username
and my lmtp users are of the form:
<username at domain>
Where domain is fairly redundant but does carry some useful information.
Now, I can proxy lmtp using user=%{username} and
destuser=%{orig_user}, and this all appears to work correctly.

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

Proxy logging destuser
Hi All
My first post to the list, so "hello world"!
Having searched the list archives and the wiki for an answer to this, I
don't think it is possible. However, let me ask nonetheless...
Is it possible for a Dovecot proxy's login process (IMAP and POP3) to
include the "destuser", i.e. the uid used to authenticate to the backend
IMAP/POP3 server, in its logging?

IMAP proxy configuration
i know dovecot can act as IMAP and POP3 proxy ..... but i'm having
a hard time configuring it. Actually i'm using a simple dovecot

problem with proxy setup
Hi all,
i have some troubles in the implementation of my proxyconfiguration.
i have two kind of users, the first will be proxied to a dovecot backend
with masteruser-login, the other one will be proxied to another
non-dovecot imapserver with nopassword.
Everything looks to work if i use passwd-file like this:

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 the particular machine on the

custom userdb server, Exim, and proxying
Hi all,
We 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

NTLM oddities
Started implementing the MasterUser changes to my config files so I can
finally offer SPA for pop3/imap.
Things are working fine with the MasterUser (horray!), however one of my
guys started using SPA with Outlook Express and started getting another
users mailbox.
Turns out to be related to NTLM. His Outlook express is configured for the
username of 'johnsmith'. However, you'll see

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

Proxying improvements in v2.1.2
I just committed a couple of features that will make life easier for some types of proxying setups:
1. IMAP proxying has already for a while supported sending local/remote IP/port to backend server, which can use it for logging and other purposes. I've now implemented this for POP3 as well, although only the remote IP/port is forwarded, not local IP/port. I implemented this also for LMTP in

Proxy to gmail not working
Hi,
I've been trying to build a password forwarding proxy to Gmail without
success... The SSL connection to Dovecot is happening no problem (as far as
I can tell), but for some reason the conversation between Dovecot and Gmail
is getting timed out.
I know this is supposed to be simple... :-( But could somebody please
give me some help by pointing what I'm not doing right?
