DESCRIPTION
With this output module it's possible to log messages via email and it used Net::SMTP to do it. The date for the email is generated with "Email::Date::format_date".

Net::SMTP is from Graham Barr and it does it's job very well.

METHODS

  new()
Call "new()" to create a new Log::Handler::Output::Email object.

The following opts are possible:

host
    With this option you has to define the SMTP host to connect to.

        host => "mx.host.com"

        # or

        host => [ "mx.host.example", "mx.host-backup.example" ]

hello
    Identify yourself with a HELO. The default is set to "EHLO BELO".

timeout
    With this option you can set the maximum time in seconds to wait for a response from the SMTP server. The default is set to 120 seconds.

from
    The sender address (MAIL FROM).

to  The receipient address (RCPT TO).

    Additional options are cc and bcc.

subject
    The subject of the mail.

    The default subject is "Log message from $progname".

buffer
    This opts exists only for security. The thing is that it would be very bad if something wents wrong in your program and hundreds of mails would be send. For this reason you can set a buffer to take care.

    With the buffer you can set the maximum size of the buffer in lines. If you set

        buffer => 10

    then 10 messages would be buffered. Set "buffer" to 0 if you want to disable the buffer.

    The default buffer size is set to 20.

debug
    With this option it's possible to enable debugging. The information can be intercepted with $SIG{__WARN__}.

  log()
Call "log()" if you want to log a message as email.

If you set a buffer size then the message will be pushed into the buffer first.

Example:

    $email->log(message => "this message will be mailed");

If you pass the level then its placed into the subject:

    $email->log(message => "foo", level => "INFO");
    $email->log(message => "bar", level => "ERROR");
    $email->log(message => "baz", level => "DEBUG");

The lowest level is used:

    Subject: ERROR: ...

You can pass the level with "Log::Handler" by setting

    message_pattern => '%L'

  flush()
Call "flush()" if you want to flush the buffered lines.

  sendmail()
Call "sendmail()" if you want to send an email.

The difference to "log()" is that the message won't be buffered.

  validate()
Validate a configuration.

  reload()
Reload with a new configuration.

  errstr()
This function returns the last error message.

DESTROY
"DESTROY" is defined and called "flush()".

PREREQUISITES

    Params::Validate
