Internet and email access are an essential
(and expensive) resource in any company. An email system is critical
to business communications, and Internet access is a vital tool.
Both are only effective when managed properly. An effective internet
solution must be reliable, responsive, flexible, and easy to manage.
Scrat is Funky Penguin's Internet
gateway solution. Scrat provides and manages
your internet and email access.
qmail is a modern SMTP server which makes
sendmail obsolete, written by Dan Bernstein, who also has a web
page for qmail. qmail is a secure package.

qmail: Hotmail's outgoing mail (although Microsoft thinks they're
going to transition to W2K), USA.net's outgoing email, Address.com,
Rediffmail.com, Colonize.com, Yahoo! mail, Network Solutions,
Verio, MessageLabs (searching 20M emails/week for malware)

interface for creation / modification of email accounts

- Delete an email account
- Change a password
- Change mailing list subscriptions

files, mp3s), file size, filename, etc. Exceptions to these
blocks can be made on a per-user basis. Blocked emails can be
"released" via a web interface.
