okay.
Lad Dir gen-auth <http://www.jetmore.org/john/code/gen-auth> runter, und führe
es aus, um Dir einen Authentifizierungsstring zu bauen:
$ gen-auth plain
username: foo at example.de
password:
Auth String: AGZvb0BleGFtcGxlLmRlAGJhcg==
Dann telnet auf Deinen Server, sage EHLO und dann "AUTH PLAIN
AGZvb0BleGFtcGxlLmRlAGJhcg==". Was sagt er dann?
$ telnet localhost 25
220 mail.state-of-mind.de ESMTP Postfix (2.5-20071006)
EHLO foo
250-mail.state-of-mind.de
250-PIPELINING
250-SIZE 40960000
250-ETRN
250-STARTTLS
250-AUTH PLAIN CRAM-MD5 LOGIN DIGEST-MD5
250-AUTH=PLAIN CRAM-MD5 LOGIN DIGEST-MD5
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
AUTH PLAIN AGZvb0BleGFtcGxlLmRlAGJhcg==
535 5.7.8 Error: authentication failed: authentication failure
QUIT
221 2.0.0 Bye
Connection closed by foreign host.
