OT: a perl script to remail mbox email

[Ken A]

I use this to split large mailboxes into separate files named
message.0001...

------- snip -----

#!/usr/bin/perl
$progname = 'mailsplit';
$tag = '^From ';
$n = 1;
$is_open = 0;
while( <> )
{
         if( $_ =~ /$tag/ )
         {
                 close( FILE) if $is_open;
                 $file = sprintf( "message.%04d", $n);
                 open( FILE, ">$file") || die "$progname: $! ($file)\n";
                 $is_open = 1;
                 $n++;
         }
         print( FILE $_);
}
close( FILE) if FILE;

------ snip ------

The problem that complicates this is that the header "To :" field may
not be the same as the envelope recipient, and may contain several email
addresses (meaning you'll have duplicate emails in the trash mbox too).

You'd actually have to grep the log by msgid for the original recipient
to match these up I think. How tough this is depends on what your idea
of fun is. :-)
