Super Fast Email Delivery & Receipt
SnugServer will transmit mails using a multithreaded
architecture which can be finely tuned to suit the power of your
physical server.
Inbound emails are processed by our carefully designed engine
that balances performance with enhanced functionality.
When SnugServer is sending attachments, it gives you the option
of compressing them in Zip format. This saves on
bandwidth.
SnugServer ensures that the connection
domains of high frequency-use are cached so that emails
sent to these domains is even faster i.e. the DNS server does
not have to be contacted each time.

SnugServer Spam scanner is done at the Server, so that spam
emails never reach the Inbox and only authentic mails are seen
by the user. Most anti-spamming software works on spam at Email
Client level where the spam has already reached the Inbox, not
so with Snug, it works at Server level.
SnugServer's Anti-Spam engine uses Plug-in architecture,
therefore you can even create your own Plug-in.
SnugServer uses the very latest in superior Anti-Spamming
plug-in techniques:
Tracking Email Killer (HTML Emails): scans emails for
External Image Links, <IFRAME>, HTML comments, Scripts and
random characters after HTML attributes and classifies them as
Spam.
Bayesian Spam Filters: calculates the probability of a
message being spam based on its contents. They learn from spam
and from good mail, resulting in a very robust efficient
anti-spam approach, that returns hardly any false positives.
This method analyses the email Header and Body.
Spam IP Filtering (Internet Blacklist ORDB Filtering):
checks the ORDB (Open Relay Databases) for IP addresses of Known
Spammers, and therefore prohibits contact with them.
BW List Filtering (Friends/Enemies List Filtering): you
enter email addresses or IP's into the Black list or the White
list so Snug knows what to prohibit/allow.
Regular Expression: you enter spam words used regularly and
mark them as Spam. This method analyses the email Header
and Body.
Email Attachment Filtering: You can decide what attachments
are allowed travel through SnugServer and whether those
attachments should be quarantined, deleted or compressed.
Strips Attachments: You can configure SnugServer to strip
Attachments from Emails. This will protect you from any
known attacks on MIME emails used by viruses in order to spread
themselves.
Strips HTML: You can configure SnugServer to strip HTML from
Emails. Hackers/virus writers can embed code to trigger
commands in HTML mail. This will protect you from any known
attacks on HTML emails.
You can control access to your SnugServer by:
Banning or Allowing certain IP Addresses
Banning or Allowing certain Countries

Anti-Spam Plugin Engine
WITHOUT Snug Anti-Spam Protection
all spam emails go straight into the INBOX
EVEN IF you have Anti-Spam software installed
on your computer
Typical Anti-Spam software works on the Email Client
SnugServer's Anti-Spam Engine works on the Email Server,
So the User never gets to see Spam.

SSL & TLS Security
SnugServer gives users the choice of using the
SSL Protocol (Secure Socket Layer)/TLS (Transport Layer
Security) Protocol when transmitting any data across the
Internet. This includes sending/receiving emails, news,
file transfer using the Snug FTP Server and any Internet
browsing using the Snug Web Browser.
The type of encryption used depends on what authentication
type (SSL/TLS) the external server allows. See
Encryption
explained.
Digital Certificates
SnugServer allows you to create your own Digital
Certification Key to ensure secure communication. It
also allows you to become a Certification Authority
whereby you can then authenticate your Digital Key.
What is a Digital Certificate?
S/MIME
SnugServer digitally encodes emails using S/MIME.
S/MIME (Secure Multi-Purpose Internet Mail Extensions) is a
secure method of sending e-mail that uses the RSA encryption
system.
RSA (Rivest-Shamir-Adleman) is an Internet encryption and
authentication system that uses an algorithm developed in
1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. The RSA
algorithm is the most commonly used encryption and
authentication algorithm.
S/MIME was created to solve email interception and forgery.
The objective of S/MIME is to protect sensitive data from
prying eyes.
The two basic features of this type of security are privacy
(only the intended recipient can read the message) and
authentication (the recipient can be assured of the identity
of the sender).

SECURITY: SMTP/POP3 Authentication Login |
SMTP/ESMTP Authentication Login Security
SnugServer uses SASL (Simple Authentication & Security
Layer) which supports the following types of Authentication:
Note: the type of Authentication actually used is dependent on
what the Email Client actually supports.
CRAM-MD5 (Challenge-Response Authentication Mechanism)
The server sends a challenge to the client in the form of a
string of random digits, a timestamp and server domain name.
The client responds with a string containing the user name and a
keyed-MD5 digest value which consists of the users password (in
encrypted format).
For example:
Server: 54545@645869512@aol.com
Client: cscott 49d8a54542gg8f4454546
PLAIN Login using Plain text.
LOGIN
cscott@abc.com
POP3 Authentication Login Security
SnugServer allows for the following types of authentication:
CRAM-MD5 (Challenge-Response Authentication Mechanism)
PLAIN
Login using Plain text.
LOGIN
cscott@abc.com

SECURITY: General Security
|
General Security
If you are using your ISP as a mail server, there is always the
possibility that outsiders could be reading your email messages.
This could prove an issue with confidential information e.g.
bank/tax details, credit card information and so on.
Snug Server offers you that security. Delivery and receipt
of emails is handled by your own company.
Global Company Disclaimer
You can add a company disclaimer at the end of each email
sent.
