fatal: no SASL authentication mechanisms

[Matthias Doering]

Hi,

Ich versuche gerade ein neues Mailsetup zu bauen. Postfix und Dovecot 
auf getrennten Hosts.
Bisher habe Ich Dovecot immer über den Unixsocket angesprochen.
Ich erhalte jetzt immer nur die Fehlermeldung (fatal: no SASL 
authentication mechanisms) bei einem telnet localhost 25.
Ich verstehe es nicht. Hat jemand ein Ansatz für mich?

<code>
Jul 28 20:22:09 mail01 postfix/smtpd[11246]: connect from 
localhost[127.0.0.1]
Jul 28 20:22:09 mail01 postfix/smtpd[11246]: fatal: no SASL 
authentication mechanisms
</code>

Hier die Configs. Ich kann keine Unterschiede hierzu sehen. 
http://dokuwiki.nausch.org/doku.php/centos:mail_c7:mta_8#konfiguration1

Der SASL-Port auf dem Dovecot-Host ist auch offen:

<code>
lsof -i :3659
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
dovecot 9043 root   41u  IPv4  30132      0t0  TCP 
dovecot01.mldsc.local:3659 (LISTEN)
</code>
