check_smtp Bug / How to send DATA by Commands?

[Daniel Fischer]

Hello,

we want to use check_smtp to check an email delivery for an internal
SMTP server. Several commands and responses were specified for this.
Unfortunately, a timeout occurs. After checking the source code (Git), a
response is obviously expected for each command. When transferring DATA
with several lines (required), the timeout occurs due to missing
response till closing the data transfer with ".".

Can this be fixed/worked around? Is there an alternative approach that
could work around the problem?

Commands
HELO seele.com
MAIL FROM:<check at seele.com>
RCPT TO:<james at seele.com>
DATA
Subject: Testmail Jame
From: <check at seele.com>
To: <james at seele.com>
Inhalt
.

Can you please help us with this issue?
