This perl script will print the contents of your postfix access file:

#!/usr/bin/perl

use DB_File;

$db = '/etc/postfix/access.db';

if (not(dbmopen %accessfile, $db, 0644)){
        die "Couldn't open $db: $!";
}

print "Contents of access file \n";

while (($key, $val) = each %accessfile) {
        write;
}
dbmclose (%accessfile);

## spit out some whitespace for good measure
print "\n\n";

format top =
 
Postfix Access File
 
Host/Domain Action
-----------------------------------------------------------------
.
 
format STDOUT =
<<<<<<<<<<<<<<<<<<<<<<<<<<< <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
$key, $val
.

# exit nicely ;-)
exit 0;

You could modify it to accept an argument and then print out your
postmap'ed files at will.
