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

NULL for password and proxy fields
In the course of experimenting with getting dovecot proxying to work,
I took a guess at two things. These work fine for me, but now I'm
wondering if they are "as designed" or just a lucky accident that
might stop working in the future.
(I'm using dovecot 1.0.rc17, which is the included version in Ubuntu
Feisty. (I am aware that some details change in v1.1, and I'm not

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

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 = \

IMAP proxy - can it detect parodying to itself?
Hi all,
I have some IMAP servers fronted with separate perdition processes, and it would be ideal if I could collapse this down to having dovecot do both the IMAP proxying and the IMAP serving at the same time on the same IP addresses.
One of the fields in my LDAP entries contains the canonical name of the server that hosts their mailbox, and if I follow the manual at

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

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

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.

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

IMAP "freezing" on OSX
Hi,
I've got a problem with dovecot on an Intel Mac OSX box. Basically, I
was running an older verion (0.8.?, I think), and everything was fine.
Then, when I upgraded to 1.0.0 via MacPorts, I found that periodically
the system gets into a state where it simply stops dealing with IMAP
requests.
This tends to manifest itself as Thunderbird simply stalling, not

passing quota to deliver via command line
Is there any way to pass things like "quota=" for the quota plugin to
the deliver LDA via the command line or as an environment variable or
whatever? I've got all the info I need in my MTA to avoid a userdb
lookup in the LDA, but I still have to do the userdb query to get the
per-user quota number (the default quota works fine, of course).

multiple ports, different characteristics
The wiki <http://wiki.dovecot.org/Iptables> leads me to believe that
the only way to configure dovecot to listen for the same protocol on
multiple ports is via external redirection (iptables or similar). Is
that so, or can dovecot be directly configured to listen on multiple
ports?
Here's a concrete example of what I'm trying to accomplish. Our
environment uses plaintext

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

Metadata/DebugInfo in *.ll file
Hi list,
I found relevant documentation regarding DebugInfo creation in the LLVM IR
bytecode. It can be done for compileunits, functions, and other constructs,
with the help of DIBuilder class. However I can't save debug information
related to individual llvm::Instructions. I tried DebugLoc, DILocation
setting directly with setMetadata(). I tried other ways, for e.g.:

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

Is there a "connect acl" ?
Hi,
I have been reading the acl documentation and it seems that a "connect acl"
is not available.
I need to limit the users that can login in an IP number, is that
posible with
dovecot 1.0? (i.e. only these users can login from the Internet)
Or a new plugin should be written? It is complicated to do that?
Thanks
