Log::Dispatch::Email - Base class for objects that send log messages via email


version 2.71


  package Log::Dispatch::Email::MySender;

  use Log::Dispatch::Email;
  use base qw( Log::Dispatch::Email );

  sub send_email {
      my $self = shift;
      my %p    = @_;

      # Send email somehow. Message is in $p{message}


This module should be used as a base class to implement Log::Dispatch::* objects that send their log messages via email. Implementing a subclass simply requires the code shown in the "SYNOPSIS" with a real implementation of the send_email() method.


The constructor takes the following parameters in addition to the standard parameters documented in Log::Dispatch::Output:

  • subject ($)

    The subject of the email messages which are sent. Defaults to "$0: log email"

  • to ($ or \@)

    Either a string or a list reference of strings containing email addresses. Required.

  • from ($)

    A string containing an email address. This is optional and may not work with all mail sending methods.

  • buffered (0 or 1)

    This determines whether the object sends one email per message it is given or whether it stores them up and sends them all at once. The default is to buffer messages.


This class provides the following methods:


This is the method that must be subclassed. For now the only parameter in the hash is 'message'.


If the object is buffered, then this method will call the send_email() method to send the contents of the buffer and then clear the buffer.


On destruction, the object will call flush() to send any pending email.
