Greetings,
I'm am learning about running a mail server and I set up a brand new
Ubuntu 14.04 server with postfix and dovecot. I had some initial
problems with dovecot not starting, and then with not having proper
permissions/access to the various directories and files and pipes, etc,
and in the process starting to learn how this thing works.
After searching in web-land I seem to have overcome those issues and
dovecot and postfix both start and accept connections now
(http://wiki2.dovecot.org/TestPop3Installation).
However when I check to see if I can authenticate I get Authentication
Failed. At the time of these login attempts there are no messages added
to syslog or mail.log, dovecot log entries are below.
Note I redacted my test user and password values to 'xxxxx', and my
domain value to 'domain.com'. Also I'm testing with my plain text
password, but I've tried using AUTH PLAIN <base64 encoded uid/pwd>. I
have also tried the setup with a default auth domain, and I've tried
authenticating with and without the domain name as part of the user
name, with the same results. I added the debug settings and
disable_plaintext_auth = no to try to solve this issue.
Here is my test command set:
xxxxx at apacweb:~$ sudo doveadm user xxxxx
field valueuserdb lookup: user xxxxx doesn't exist
and :
xxxxx at apacweb:~$ telnet localhost 110
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK Dovecot (Ubuntu) ready.
user xxxxx
+OK
pass xxxxx
-ERR [AUTH] Authentication failed.
Here is a cut from the dovecot log:
2014-06-08 01:22:10 auth: Error: passwd-file(xxxxx): stat(uid=vmail
gid=vmail home=/home/vmail//xxxxx /etc/dovecot/users) failed: Address
family not supported by protocol
I figure this is the root cause of this issue and the solution to it is
supposedly to tell dovecot to not listen on IPv6 (listen = *), but I did
that and it didn't help (see config).
Here is a cut from the dovecot.info log:

driver = passwd-file
}
valid_chroot_dirs = /var/spool/vmail
protocol pop3 {
pop3_uidl_format = %08Xu%08Xv
}
I'm sure I've done something stupid, but after thrashing about for some
days I haven't been able to figure out what it is.
