NAME ^

Mail::Audit::Attach - Mail::Audit plugin for attachment handling.

SYNOPSIS ^

  use Mail::Audit qw(Attach);

  my $mail = Mail::Audit->new;

  # ...

  my $num_attachment = $mail->num_attachments;
  my $attachments = $mail->attachments;

  remove_attachments(filename => "\.(exe|scr|pif)",
                     smaller_than => 20000);

  $mail->remove_attachments(mime_type => "text/html");

  foreach (@$attachments) {
      $_->save($attachdir) 
          if ($_->mime_type =~ |^image/|);
      $_->remove 
          if ($_->filename =~ |\.(vcf)$|);
  }

  $mail->make_singlepart; # if possible

DEFINITION ^

For the purpose of this plugin, an attachment is a MIME part that has a filename. Files attached to non-MIME messages will not be discovered.

DESCRIPTION ^

This is a Mail::Audit plugin which provides easy access to files attached to mail messages. Besides Mail::Audit, it requires the MIME::Entity module.

CONSTRUCTOR

new

This constructor is called by Mail::Audit; it should not be necessary to create a Mail::Audit::Attach object manually.

METHODS IN MAIL::AUDIT

num_attachments

Returns the number of attachments found

attachments

Returns a reference to a list of attachment objects

error

Returns a string with an error message (if an error ocurred).

remove_attachments

Removes attachments from the mail that match the criteria specified via the options, or all, if no options are specified. Currently, the following options (hash keys) are supported:

mime_type
file_name

Specify a regular expression; attachments whose MIME type or filename matches this expression are removed.

smaller_than
bigger_than

Specify file size limits; attachments smaller or bigger than these limits are removed.

An attachment must match all of the criteria to be removed. Returns the number of attachments removed.

ATTACHMENT PROPERTIES

The attachments are a subclass of MIME::Entity. Check out MIME::Entity to learn about useful methods like mime_type or bodyhandle that are inherited.

size

Returns the size of the attached file.

filename

Returns the original filename given in the MIME headers.

safe_filename

Returns the filename, with /\:;[]| and whitespace replaced by underscores, or 'attachment' if the original filename is empty.

ATTACHMENT ACTIONS

remove

Removes the attachment, ie. detaches the corresponding MIME entity and purges the body data.

save($location)

Saves the attachment as a file in $location. If $location is a directory (ie if -d $location), save uses safe_filename to store the file inside that directory, else $location is assumed to be a fully-qualified path with filename.

In both cases, save checks whether the target file exists and appends '.n' to the filename, with n being an integer that leads to a unique filename, if necessary.

Returns the filename used to save the file, or undef if an error ocurred (you might want to take a look at Mail::Audit::Attach::error in that case).

Note that the attachment is not removed.

ERROR FUNCTION

Mail::Audit::Attach::error will return an error message if an action failed (currently only set by save).

HISTORY ^

0.96, 2010-02-28
    - Fixed POD bug introduced in 0.95
    - Upgraded to Makefile.PL in the style of Alexandr Ciornii (v0.21)
0.95, 2010-02-26
    - Created GitHub repository
    - Fixed RT#19546: Added missing dependency MIME::Base64
0.94 Sun Jun 05 23:00:00 2005
    - Updated distribution to more modern format.
    - Added POD tests.
0.93 Sat Apr 14 00:30:00 2003
    - Mail::Audit->save died when passed an empty location. Fixed.
      location is now optional.
    - Now uses File::Spec for more portability
    - Introduced Mail::Audit::error (used by save)
    - Localized $_ where used
0.92 Sat Feb 8 13:00:00 2003
        - Now relies on MIME::Head to recognize attachments.
          "Never try to be too clever."
        - No more warnings.
0.91 Thu Feb 6 22:30:00 2003
  - Now recognizes attachments with Content-Disposition inline,
    but a given filename. This became necessary because Netscape
        Communicator and other clients send their attachments that way.

          Thanks to Jeff Engelhardt and Vladimir Parkhaev for bringing
          this to my attention.
