check_smtp and authentication

[Alex Domoradov]

Hello all,

Is anyone could give a work example of the check_smtp plugin? I just
want to send mail via out smtp relay with authentication.

I have tried the following example

# ./check_smtp -H mail.example.net -A LOGIN -U user at example.net -P
1234567 --starttls -v --fqdn=www.example.net -C "mail
from:<user at example.net>" -C "rcpt to:<user at gmail.com>" -C "DATA" -C
"Hello world" -C "." -C "quit"
HELOCMD: EHLO www.example.net
220 mail.psd2html.com ESMTP
sent EHLO www.example.net
250-mail.example.net
250-PIPELINING
250-SIZE 20971520
250-ETRN
250-AUTH LOGIN CRAM-MD5 PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
sent AUTH LOGIN
received 334 VXNlcm5hbWU6

sent YWtbC5jb20RvbW9yYWRvdkBwc2QyaHR=

received 334 UGFdvcmQ6zc3

sent TUxg5cXVQbTcDg==

received 235 2.7.0 Authentication successful

sent QUIT
received 221 2.0.0 Bye

SMTP OK - 1.693 sec. response time, 221 2.0.0 Bye
|time=1.692533s;;;0.000000

But at the same time in mail lof I get the following lines

Feb 17 19:33:13 mail postfix/smtpd[14943]: connect from
www.example.net[xxx.xxx.xxx.xxx]
Feb 17 19:33:14 mail postfix/smtpd[14943]: Anonymous TLS connection
established from www.example.net[xxx.xxx.xxx.xxx]: TLSv1.2 with cipher
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
Feb 17 19:33:15 mail postfix/smtpd[14943]: disconnect from
www.example.net[xxx.xxx.xxx.xxx]


How can I send some data?
