[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - a follow-up

[Axel Luttgens]

Suspecting a problem with the "virtual" uids/gids, I've tried with a real user 
for the mail user:

        # 2.1.14: /_ETC/dovecot/dovecot.conf
        # OS: Darwin 12.2.1 x86_64  
        auth_verbose = yes
        disable_plaintext_auth = no
        mail_debug = yes
        mail_gid = dovemailer
        mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox
        mail_uid = dovemailer
        passdb {
          args = /_ETC/dovecot/db.conf
          driver = sql
        }
        ssl = no
        userdb {
          driver = prefetch
        }

Of course, the db queries do not return uid/gid pairs anymore.

And the pop3 processes now seem to work as expected; connecting for the first 
time as user1:

        $ telnet 127.0.0.1 110
        Trying 127.0.0.1...
        Connected to localhost.
        Escape character is '^]'.
        +OK Dovecot ready.
        user user1
        +OK
        pass pass1
        +OK Logged in.
        list
        +OK 0 messages:
        .
        quit
        +OK Logging out.
        Connection closed by foreign host.

Hmmm...
