auth_username_translation and LTMP problem
auth_username_translation seems to be appliet on RCPT TO address of LTMP transport. Why dovecot is doing that? And better question - is there a way to disable auth_username_translation for LTMP but leave enabled for the rest (imap, pop3 etc) ? Background: I'm doing auth_username_translation = @= to allow logins like aaa at bbb.pl to be internally translated to aaa=bbb.pl. That works

Problem getting a dovecot proxy to connect to another dovecot machine via STARTTLS
Hi, I'm having a bit of a problem trying to setup a dovecot proxy. I have a setup with two nodes. One is a working Dovecot/Postfix mail server (node a). The other is running a dovecot proxy and roundcube webmail. Currently I can telnet to port 143 (or openssl s_client to port 993) to localhost on node b. I can then login to a test account on node a. This all works. However, once I instruct

director directing to wrong server (sometimes)
Hello, I have discovered a strange behaviour with director proxying... I have a user, its assigned server is 155.54.211.164. The problem is that I don't know why director sent him yesterday to a different server, because my server was up all the time. Moreover, I'm using poolmon in director servers to check availability of final servers and it didn't report any problem with the

Problems with the IMAP proxy after upgrading from dovecot 1.1.16 to 1.211
We have frequent timeout problems after upgrading our imap servers from dovecot 1.1.16 to dovecot 1.2.11. One server acts as proxy only, and the other one is the "real" imap server". The credentials for the proxy service are stored in a remote MYSQL database. There were no trouble with dovecot 1.1.16. But now, with the most recent version, we get frequent login failures. It

POP3-Proxy error
Hi, as mentioned in another thread I discovered a crash in the pop3-proxy. It occurs when the remote-pop3-server just drops the connection (in my case courier was hitting the MAXPERIP-Limit). I don't have a corefile yet, but will try to get one. Here the message from the dovecot.log: dovecot: Feb 02 09:30:00 Error: pop3-login: file pop3-proxy.c: line 20 (proxy_input): assertion failed:

lmpt director and ldap userdb
Hello, I've been using dovecot for a long time, but now I'm having troubles with I change I need to make. I have a director server in front of two backend servers. All of these servers are running dovecot 2.1.16. Redirection to backend servers are based in an attribute of a ldap server. My users are defined in this same ldap server. At this moment, for user authentication we use

real_rip variable addition for dovecot 2.1.10
Timo, Please check the code. I didn't add it, but a real_lip might be useful for some people as well. Also, I notice that pop3-proxy is doing a different xsession than the imap proxy. Is there an xsession standard that is different between the two, or just an oversight in the code? Both send the remote address/port, but only imap proxy sends the local address/port. This patch declares

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? No matter

doveadm commands returning 139 at director servers
Hello, I have configured director in front of dovecot imap/pop/lmtp servers. When I need to manipulate a user mailbox, I use doveadm commands at director server's, with -S option. But some commands return exit code 139 when command returns more than 40 entries (I think). For example, the command: sudo doveadm fetch -u amateo hdr mailbox Trash HEADER Subject "nyctalus11/"

director's imap/pop3 login timeout
Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41

Dovecot proxy: per user/domain 'namespace/inbox/prefix' from MySQL
As a way to try and avoid using "prefix = INBOX." ad infinitum for the inbox namespace, I'm looking for ways to move on to "prefix =" for new mail accounts, and grandfather the existing ones. Previously running Courier-IMAP, now Dovecot, I looked at https://wiki.dovecot.org/Namespaces#Backwards_Compatibility:_Courier_IMAP and decided it's too risky to go down that

Patch for SSH-tunneling via HTTPS-proxy
Hi List, I have a szenario where I need to reach a host on the internet from a "firewalled" network but there is a HTTPS-proxy runnnig. As some people know you can tunnel all TCP-connections through this proxy because it can't decide if someone is really doing SSL or just Telnet to port 443 (or use SSH in our case). So I've written a patch for ssh to make it send the CONNECT
