Best practice for bulk multi-part mail
Hi, I am currently building a PHP/MySQL database that handles our offices newsletters. Now everything works great in the alpha with only a few names in the list, but I anticipate that once we fill it up (around 10,000) that this will not work from the PHP. I already have the script echo the emails to a database where I plan to have a cron perl script grab the info and send it to the Mail Transport Agent in chuncks. Now, I am completely new to perl, and it's been awhile since I did any work in unix, so go easy on me. Here are my questions if anyone can help.

I've seen some shell scripts that can send emails pretty easy, but they don't appear to be able to adjust the header information. I need to change, the From, and send as a multi-part text/plain text/html. Is there something I am missing?
Why is it so much harder to cron a php script than perl script for this? (Is it because the shells understand perl better?)
What is the best Perl package for sending multi-part emails? Quickly?
What is the best (free) MTA To use?

Thanks for the time,
_Stephen

       myloader - multi-threaded MySQL loader

SYNOPSIS

       myloader --directory = /path/to/mydumper/backup [OPTIONS]

DESCRIPTION

       myloader is a tool used for multi-threaded restoration of mydumper backups.

OPTIONS

       The myloader tool has several available options:

       --help Show help text

       --host, -h
	      Hostname of MySQL server to connect to (default localhost)

       --user, -u
	      MySQL username with the correct privileges to execute the restoration

       --password, -p
	      The corresponding password for the MySQL user

       --port, -P
	      The port for the MySQL connection.

       Note   For localhost TCP connections use 127.0.0.1 for --host.

       --socket, -S
	      The UNIX domain socket file to use for the connection

       --threads, -t

       Note   For  use with single database dumps.  When using with multi-database dumps that have duplicate table names in more than one database

       --overwrite-tables, -o
