Many people simply pipe mail received by either an MTA or MUA to a process. An MTA, such as sendmail, can receive mail and pipe it to a process. Often, mail is received by an MTA and sent to a user mailbox via a local MUA, and the MUA forwards the mail, via a pipe, to the standard-in.
Often, in a .forward file in a user directory has something like,
"|/home/user/bin/myprocess".
Or, in a file like the sendmail aliases file:
joe.user: "|/home/user/bin/myprocess"
There are many reasons to do this, a person can simply send mail to a host and in the message have embedded tokens that could be used for anything imaginable... for example, you could send a message to a user aliase and have an embedded command (with embedded security) telling your home computer to turn off the lights in your house (if you had a interface to your home lighting)....
You can literally do anything you can imagine by sending mail to a process.... your imagination is the limit.... you could send mail to our home computer and with an embedded token that could be used by a process to activate a video camera, another example.

log::handler::output::email
Log::Handler::Output::Email(3pm) User Contributed Perl Documentation Log::Handler::Output::Email(3pm)
NAME
Log::Handler::Output::Email - Log messages as email (via Net::SMTP).
SYNOPSIS
use Log::Handler::Output::Email;
my $email = Log::Handler::Output::Email->new(
host => "mx.bar.example",
hello => "EHLO my.domain.example",
timeout => 120,
debug => 0,
from => 'bar@foo.example',
to => 'foo@bar.example',
subject => "your subject",
buffer => 0
);
$email->log(message => $message);
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
Carp
Email::Date
Net::SMTP
Params::Validate
EXPORTS
No exports.
REPORT BUGS
Please report all bugs to <jschulz.cpan(at)bloonix.de>.
If you send me a mail then add Log::Handler into the subject.
