Email::Sender::Failure(3pm)				User Contributed Perl Documentation			       Email::Sender::Failure(3pm)

NAME
Email::Sender::Failure - a report of failure from an email sending transport VERSION
version 0.110005 ATTRIBUTES
message This method returns the failure message, which should describe the failure. Failures stringify to this message. code This returns the numeric code of the failure, if any. This is mostly useful for network protocol transports like SMTP. This may be undefined. recipients This returns a list (or, in scalar context, an arrayref) of addresses to which the email could not be sent. METHODS
throw This method can be used to instantiate and throw an Email::Sender::Failure object at once. Email::Sender::Failure->throw(\%arg); Instead of a hashref of args, you can pass a single string argument which will be used as the "message" of the new failure. SEE ALSO
