4.2.8 Sendmail
The
sendmail
tool can be used to send emails from the device. The sendmail tool is based on busybox and has
no configuration files. Everything is passed via command line.
The mail is passed using stdin. For a simple test, the following can be put to into mail.txt
From: <[email protected]>
To: <[email protected]>
Subject: Mail Header
Hello,
This is the mail body text.
Note that the empty line between subject and email text is part of the mail format and needs to be preserved!
This mail can be sent with:
sendmail
-f <[email protected]> -S <smtpserver>
,!
< mail.txt
The example requires an SMTP server at <smtpserver> on port 25 without authentication. For enabling authen-
tication and encryption read the manuals for sendmail/busybox sendmail.
