DESCRIPTION

Log::Fine::Handle::Email provides formatted message delivery to one or more email addresses. The intended use is for programs that need to alert a user in the event of a critical condition. Conceivably, the destination address could be a pager or cell phone.

Implementation Details

Log::Fine::Handle::Email uses the Email::Sender framework for delivery of emails. Users who wish to use Log::Fine::Handle::Email are strongly encouraged to read the following documentation:

Be especially mindful of the following environment variables as they will take precedence when defining a transport:

  • EMAIL_SENDER_TRANSPORT

  • EMAIL_SENDER_TRANSPORT_host

  • EMAIL_SENDER_TRANSPORT_port

See Email::Sender::Manual::Quickstart for further details.

Email Address Validation

Log::Fine::Handle::Email will validate each email addresses prior to use. Upon initilization, L::F::H::E will search for and use the following email address validation modules in the following order of preference:

Should neither Mail::RFC822::Address nor Email::Valid be found, then a default regex will be used which should work for most instances. See CAVEATS for special considerations.

Constructor Parameters

The following parameters can be passed to Log::Fine::Handle::Email->new();

  • name

    [optional] Name of this object (see Log::Fine). Will be auto-set if not specified.

  • mask

    Mask to set the handle to (see Log::Fine::Handle)

  • subject_formatter

    A Log::Fine::Formatter object. Will be used to format the Email Subject Line.

  • body_formatter

    A Log::Fine::Formatter object. Will be used to format the body of the message.

  • header_from

    String containing text to be placed in "From" header of generated email.

  • header_to

    String containing text to be placed in "To" header of generated email. Optionally, this can be an array ref containing multiple addresses

  • envelope

    [optional] hash ref containing envelope information for email:

    + to

    array ref containing one or more destination addresses

    + from

    String containing email sender

    + transport

    An Email::Sender::Transport object. See Email::Sender::Manual for further details.

METHODS

msgWrite

Sends given message via Email::Sender module. Note that "_error" in Log::Fine will be called should there be a failure of delivery.

See "msgWrite" in Log::Fine::Handle

CAVEATS

Note that the Email::Valid module does not use the same checking algorithms as Mail::RFC822::Address. Email addresses considered valid under one module may not be considered valid under the other. For example, under Mail::RFC822::Address, jsmith@localhost is considered a valid address while Email::Valid will reject it. Consider researching each module prior to making a determination as to which is acceptable for your environment and needs.
