Hi,

I'm trying to use dovecot as a proxy as described on http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy but without much success. The problem is that when I send a IMAP login command dovecot is responding with "BYE Internal login failure. Refer to server log for more information." Can anyone help me shed light on this problem?

Here's the log (Username, password and IPs have been anonymised):

dovecot: Mar 27 13:07:11 Info: Dovecot v1.0.rc15 starting up dovecot: Mar 27 13:07:12 Info: auth(default): passwd-file /root/dovecot-proxy-test.passwd: Read 1 users dovecot: Mar 27 13:07:29 Info: auth(default): client in: AUTH 1

And here's my config according to dovecot -n

/root/dovecot-proxy-test.conf

base_dir: /var/run/dovecot-proxy-test log_path: /dev/stderr protocols: imap listen: *:10143 login_dir: /var/run/dovecot-proxy-test/login login_executable: /usr/libexec/dovecot/imap-login auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /root/dovecot-proxy-test.passwd userdb: driver: static args: uid=0 gid=0

/root/dovecot-proxy-test.passwd contains a single line:

test_proxy:::::::proxy=y host=192.168.0.3 port=143

I am on Cent OS 5 using dovecot version 1.0.rc15 from their official yum repositories. If I connect my client directly to 192.168.0.3:143 using the same username and password everything works correctly.

Thanks in advance.

Try getting a newer version of dovecot from atrpms.net and see if it works. Current is 1.0.13, at least a year newer then the release candidate you are using.
