SYNOPSIS

   use Email::MIME::Modifier;
   my $email = Email::MIME->new( join "", <> );
 
   remove_attachments($email);
 
   sub remove_attachments {
       my $email = shift;
       my @keep;
       foreach my $part ( $email->parts ) {
           push @keep, $part
             unless $part->header('Content-Disposition') =~ /^attachment/;
           remove_attachments($part)
             if $part->content_type =~ /^(?:multipart|message)/;
       }
       $email->parts_set( \@keep );
   }
 
 

DESCRIPTION

Provides a number of useful methods for manipulating MIME messages.

These method are declared in the "Email::MIME" namespace, and are used with "Email::MIME" objects.

Methods

content_type_set

   $email->content_type_set( 'text/html' );
 
 

Change the content type. All "Content-Type" header attributes will remain in tact.

charset_set

name_set

format_set

boundary_set

   $email->charset_set( 'utf8' );
   $email->name_set( 'some_filename.txt' );
   $email->format_set( 'flowed' );
   $email->boundary_set( undef ); # remove the boundary
 
 

These four methods modify common "Content-Type" attributes. If set to "undef", the attribute is removed. All other "Content-Type" header information is preserved when modifying an attribute.

encoding_set

   $email->encoding_set( 'base64' );
   $email->encoding_set( 'quoted-printable' );
   $email->encoding_set( '8bit' );
 
 

Convert the message body and alter the "Content-Transfer-Encoding" header using this method. Your message body, the output of the "body()" method, will remain the same. The raw body, output with the "body_raw()" method, will be changed to reflect the new encoding.

body_set

   $email->body_set( $unencoded_body_string );
 
 

This method will encode the new body you send using the encoding specified in the "Content-Transfer-Encoding" header, then set the body to the new encoded body.

This method overrides the default "body_set()" method.

disposition_set

   $email->disposition_set( 'attachment' );
 
 

Alter the "Content-Disposition" of a message. All header attributes will remain in tact.

filename_set

   $email->filename_set( 'boo.pdf' );
 
 

Sets the filename attribute in the "Content-Disposition" header. All other header information is preserved when setting this attribute.

parts_set

   $email->parts_set( \@new_parts );
 
 

Replaces the parts for an object. Accepts a reference to a list of "Email::MIME" objects, representing the new parts. If this message was originally a single part, the "Content-Type" header will be changed to "multipart/mixed", and given a new boundary attribute.

parts_add

   $email->parts_add( \@more_parts );
 
 

Adds MIME parts onto the current MIME part. This is a simple extension of "parts_set" to make our lives easier. It accepts an array reference of additional parts.

walk_parts

   $email->walk_parts(sub {
       my $part = @_;
       return if $part->parts > 1; # multipart
       
       if ( $part->content_type =~ m[text/html] ) {
           my $body = $part->body;
           $body =~ s/<link [^>]+>//; # simple filter example
           $part->body_set( $body );
       }
   });
 
 

Walks through all the MIME parts in a message and applies a callback to each. Accepts a code reference as its only argument. The code reference will be passed a single argument, the current MIME part within the top-level MIME object. All changes will be applied in place.
