dovecot - Oct 2011 - Issue after upgrading to Ubuntu Server 11.10

Hi all,

After upgrading to Ubuntu Server 11.10 my mail setup stopped working.
The error message I get is:

lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb)
failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing
+r perm: /var/run/dovecot/auth-userdb, euid is not dir owner)

Does anybody have an idea how to solve this?

Thanks,
Chris.

service imap-login {

    port = 143
  }
  inet_listener imaps {

userdb {

  driver = static
}
protocol imap {
  mail_max_userip_connections = 50
  mail_plugins = fts fts_squat
}
protocol lda {
  mail_plugins = sieve
}

I added

  unix_listener auth-userdb {
    group = vmail
    mode = 0600
    user = vmail
  }

to the configuration which seems to solve the issue.  Is this the
right solution?

Regards,
Chris.
