NAME

       check_smtp_send - connects to an SMTP server and sends a message

SYNOPSIS

        check_smtp_send -vV
        check_smtp_send -?
        check_smtp_send --help

OPTIONS

       --warning <seconds>
           Warn if it takes longer than <seconds> to connect to the SMTP server. Default is 15
           seconds.  Also known as: -w <seconds>

       --critical <seconds>
           Return a critical status if it takes longer than <seconds> to connect to the SMTP
           server. Default is 30 seconds.  Also known as: -c <seconds>

       --timeout <seconds>
           Abort with critical status if it takes longer than <seconds> to connect to the SMTP
           server. Default is 60 seconds.  The difference between timeout and critical is that,
           with the default settings, if it takes 45 seconds to connect to the server then the
           connection will succeed but the plugin will return CRITICAL because it took longer
           than 30 seconds.  Also known as: -t <seconds>

       --hostname <server>
           Address or name of the SMTP server. Examples: mail.server.com, localhost,
           192.168.1.100

           If not provided, and if there is only one --mailto address, the script will
           automatically look up the MX record for the --mailto address and use that as the
           hostname. You can use this to check that your MX records are correct.  When omitting
           the --hostname option, it doesn't really make sense to specify --port, --username, or
           --password but you can still do so and they will have their normal effect. To look up
           the MX records you need to have the module Net::DNS and Email::Address installed.

           Also known as: -H <server>

       --port <number>
           Service port on the SMTP server. Default is 25 for regular SMTP, 465 for SSL, and 587
           for TLS.  Also known as: -p <number>

       --tls
       --notls
           Enable TLS/AUTH protocol. Requires Net::SMTP::TLS, availble on CPAN.

           When using this option, the default port is 587.  You can specify a port from the
           command line using the --port option.

           Use the notls option to turn off the tls option.

           Also, you may need to fix your copy of Net::SMTP::TLS. Here is the diff against
           version 0.12:

            254c254
            <      $me->_command(sprintf("AUTH PLAIN %S",
            ---
            >      $me->_command(sprintf("AUTH PLAIN %s",

       --ssl
       --nossl
           Enable SSL protocol. Requires Net::SMTP::SSL and Authen::SASL, availble on CPAN.

           When using this option, the default port is 465. You can override with the --port
           option.

           Use the nossl option to turn off the ssl option.

       --auth <method>
           Enable authentication with Net::SMTP_auth (sold separately).  For example, try using
           --auth PLAIN or --auth CRAM-MD5.

       --username <username>
       --password <password>
           Username and password to use when connecting to SMTP server.  Also known as: -U
           <username> -P <password>

       --body <message>
           Use this option to specify the body of the email message. If you need newlines in your
           message, you might need to use the --stdin option instead.

       --header <header>
           Use this option to set an arbitrary header in the message. You can use it multiple
           times.

       --stdin
           Grab the body of the email message from stdin.

       --mailto recipient@your.net
           You can send a message to multiple recipients by repeating this option or by
           separating the email addresses with commas (no whitespace allowed):

           $ check_smtp_send -H mail.server.net --mailto recipient@your.net,recipient2@your.net
           --mailfrom sender@your.net

           SMTP SEND OK - 1 seconds

       --mailfrom sender@your.net
           Use this option to set the "from" address in the email.

       --template
       --notemplate
           Enable (or disable) processing of message body and headers. Requires Text::Template.

           Use this option to apply special processing to your message body and headers that
           allows you to use the results of arbitrary computations in the text. For example, you
           can use this feature to send a message containing the hostname of the machine that
           sent the message without customizing the plugin configuration on each machine.

           When you enable the --template option, the message body and headers are parsed by
           Text::Template. Even a message body provided using the --stdin option will be parsed.
           See the Text::Template manual for more information, but in general any expression
           written in Perl will work.

           There is one convenience function provided to you, trim, which will remove leading and
           trailing whitespace from its parameter. Here's an example:

            check_smtp_send -H mail.server.net --mailto recipient@your.net --mailfrom sender@your.net
            --template --body 'hello, this message is from {use Sys::Hostname; hostname}'
            --header 'Subject: test message from {trim(`whoami`)}'

       --expect-response <code>
           Use this option to specify which SMTP response code should be expected from the server
           after the SMTP dialog is complete. The default is 250 (message accepted).

           Also known as: -E <code>

       --hires
           Use the Time::HiRes module to measure time, if available.

       --verbose
           Display additional information. Useful for troubleshooting.

           One --verbose will show extra information for OK, WARNING, and CRITICAL status.

           Use one --verbose together with --version to see the default warning and critical
           timeout values.

           Three --verbose (or -vvv) will show debug information, unless you're using --tls
           because Net::SMTP::TLS does not have a Debug feature.

           Also known as: -v

       --version
           Display plugin version and exit.  Also known as: -V

       --help
           Display this documentation and exit. Does not work in the ePN version.  Also known as:
           -h

       --usage
           Display a short usage instruction and exit.

EXAMPLES

   Send a message with custom headers
       $ check_smtp_send -H mail.server.net --mailto recipient@your.net --mailfrom
       sender@your.net --body 'Homeruns 5' --header 'Subject: Hello, world!' --header
       'X-Your-Header: Yes'

       SMTP SEND OK - 1 seconds

EXIT CODES

       Complies with the Nagios plug-in specification:
        0        OK             The plugin was able to check the service and it appeared to be
       functioning properly
        1        Warning        The plugin was able to check the service, but it appeared to be
       above some "warning" threshold or did not appear to be working properly
        2        Critical  The plugin detected that either the service was not running or it was
       above some "critical" threshold
        3        Unknown        Invalid command line arguments were supplied to the plugin or the
       plugin was unable to check the status of the given hosts/service

NAGIOS PLUGIN NOTES

       Nagios plugin reference: http://nagiosplug.sourceforge.net/developer-guidelines.html

       This plugin does NOT use Nagios DEFAULT_SOCKET_TIMEOUT (provided by utils.pm as $TIMEOUT)
       because the path to utils.pm must be specified completely in this program and forces users
       to edit the source code if their install location is different (if they realize this is
       the problem). You can view the default timeout for this module by using the --verbose and
       --version options together.  The short form is -vV.

       Other than that, it attempts to follow published guidelines for Nagios plugins.
