Mail::Server::IMAP4::Fetch

message info for IMAP protocol speed-up

  my $imap = Mail::Server::IMAP4::Fetch->new($msg);
  print $imap->fetchBody(1);   # for FETCH BODYSTRUCTURE
  print $imap->fetchBody;      # for FETCH BODY
  print $imap->fetchEnvelope;  # for FETCH ENVELOPE
  print $imap->fetchSize;

Create a new object hierarchy, which contains information to capture the most important details about the message. The object can be used to speed-up IMAP-server implementations, as Mail::Box::Netzwert.

The object used here is a simplified representation of a Mail::Box::Message object. It does not maintain headers and does not refer to the folder. It only works with messages stored in a file. Therefore, this object can be frozen by Storable if you want to.

$obj->partLocation()

$obj->fetchBody($extended)
Returns one string, representing the message's structure as defined by the IMAP protocol. The boolean argument indicates whether you like to have the $extended information, as the imap command 'FETCH BODYSTRUCTURE' defines or the limited information of 'FETCH BODY'.
$obj->fetchEnvelope()
Returns a string representation of some header information.
$obj->fetchSize()
Returns the size of the message body.
$obj->part( [$partnr] )
The partnummer is a list of dot-separated positive integers, numbering (nested) parts in multi-part message bodies. By default, the info of the main message is returned.

» example:

  my $partinfo = $msg->info->part('1.2.1');
  print $msg->info->part('3.3')->fetchBody;
$obj->printStructure( [<$fh|undef>, [$number]] )
Print the structure of the fetch data to the specified $fh or the selected filehandle. When explicitly "undef" is specified as handle, then the output will be returned as string. Only a limited set of the information is displayed.

» example:

  my $imap = ...;
  $imap->printStructure(\*OUTPUT);
  $imap->printStructure;
  my $struct = $imap->printStructure(undef);
