Clyton

"An email client with advanced security and spam filtering features."


Clyton is a full-featured email client with advanced security and spam filtering capabilities. This is a must-have program for anyone who needs to keep their email private, or anyone swamped with spam. Although priced for the general public, Clyton possesses the reliability and security required by large companies.

Security
Security is Clyton's top priority. We've worked tirelessly to make Clyton the most secure email client available.

Connection Security
• Connections to the mail server can be secured with SSL/TLS encryption. This prevents an eavesdropper from reading your mail.
• Mail server passwords are verified using the CRAM-MD5 method, which is able to confirm the password without ever transmitting it. This prevents an eavesdropper from intercepting the password.
• Supports DomainKeys and DKIM signing and verification. This ensures that an email has not been tampered with, and that the sender has not been forged.

Internal Security
• All passwords are internally stored with encryption to ensure that they cannot be exposed, even to a user with admin rights.
• Stored messages can be encrypted to prevent them from being read by programs or persons who have access to the file system.
• Mailboxes can be password protected. This prevents mail from being read or composed even if physical access to the computer is compromised.
• Sensitive messages can be shredded in such a way that no forensic recovery is possible.

Virus Security
• Until permitted, HTML email is restricted from running scripts, loading embedded objects, and downloading media. Malware cannot infect the computer simply by viewing an email.
• The Address Book is encrypted to prevent malware from spreading to your contacts.
• The user is warned before opening dangerous attachments.
• Clyton is compatible with third-party anti-virus email scanners.

Key Features

• Built-in address book supports custom fields and import/export.
• Send personalized mass mail to a filtered set of address book contacts.
• Supports text search in a single folder or globally.
• Whitelisting prevents false positives by the spam engine. Whitelisted senders and address book contacts are never treated as spam.
