Re: Retrieving email and decoding attachments

in reply to Retrieving email and decoding attachments

This script should do what you want. I looked at several modules trying to find one that does everything, but lately I find that most mail related modules do one or two very specific things well, but for anything but the simplest tasks end up using more than one to get the job done. In this case, Mail::POP3Client is a good POP3 access tool but MIME::Parser is hard to beat for saving attachments to disk:

#!/usr/local/bin/perl
use strict;
use warnings;
use Mail::POP3Client;
use MIME::Parser;

my $pop = new Mail::POP3Client(
                 USER     => "user",
                 PASSWORD => "password",
                 HOST     => "pop3.server"
);

## for HeadAndBodyToFile() to use
my $fh = new IO::Handle();

## Initialize stuff for MIME::Parser;
my $outputdir = "./mimemail";
my $parser = new MIME::Parser;
$parser->output_dir($outputdir);

my $i;
## process all messages in pop3 inbox
for ($i = 1; $i <= $pop->Count(); $i++) {
   open (MAILOUT, ">pop3.msg$i");
   $fh->fdopen( fileno( MAILOUT ), "w" );
   ## write current msg to file
   $pop->HeadAndBodyToFile( $fh, $i );
   close MAILOUT;
   ## MIME::Parser handles only one msg at-a-time
   open (MAILIN, "<pop3.msg$i");
   ## flush all attachments this msg to ./mimemail dir using internal 
+filename
   my $entity = $parser->read(\*MAILIN);
   close MAILIN;
}

BTW, this was done hastily and could use more error testing, could probably be done more simply/elegantly, but I leave that for the poster.

Does anyone know how to read the messages directly to MIME::Parser without having to write the intermediate files first? I've encountered this dilemma recently trying to combine other unrelated mail modules.

This works too and is a bit simpler.

for ($i = 1; $i <= $pop->Count(); $i++) {
   print "$i \n";
   my $msg;
   $msg = $pop->HeadAndBody( $i );
   my $entity = $parser->parse_data($msg);
}

Thanks, works well after all these years
