MIME::Explode is perl module for parsing and decoding single or multipart MIME messages, and outputting its decoded components to a given directory ie, this module is designed to allows users to extract the attached files out of a MIME encoded email messages or mailboxes.


new([, OPTION ...])

This method create a new MIME::Explode object. The following keys are available:


Directory where the decoded files are placed

mkdir => octal_number

If the value is set to octal number then make the output_dir directory (example: mkdir => 0755).

check_content_type => 0 or 1

If the value is set to 1 the content-type of file is checked

decode_subject => 0 or 1

If the value is set to 1 then the subject is decoded into a list.

  $header->{'0.0'}->{subject}->{value} = [ARRAYREF];
  $header->{'0.0'}->{subject}->{charset} = [ARRAYREF];
  $subject = join("", @{$header->{'0.0'}->{subject}->{value}});
exclude_types => [ARRAYREF]

Not save files with specified content types (deprecated in next versions)

content_types => [ARRAYREF]

Array reference with content types for "include" or "exclude"

types_action => "include" or "exclude"

If the action is a "include", all attached files with specified content types are saved but if the action is a "exclude", no files are saved except if its in the array of content types. If no array is specified, but the action is a "include", all attached files are saved, otherwise all files are removed if action is a "exclude". The default action is "include".


This method parse the stream and splits it into its component entities. This method return a hash reference with all parts. The FILEHANDLE should be a reference to a GLOB. The second argument is optional.


Returns the number of parsed messages.


Cleans all files from the "output_dir" directory and then removes the directory. If an error happens returns it.
