The client connection control is also supported to avoid relay.

A blocked mail is either deleted, placed in an isolation zone, or delayed. In any case, a real-time message will be sent to notify the system manager.

Sets up blacklists. Source addresses include e-mail addresses, IP addresses, domain names and e-mail accounts. The built-in smart identification and rejection mechanism can block mails sent by such as resigned employees to reduce spam.

System manager will be informed immediately about isolated blocked mails or system malfunctions via e-mail or internal messaging system. Message Reporting function can be configured to notify the system manager, e-mail Sender, or Recipient of the various messages. This function can generate its own notification lists automatically too.

Mail Sherlock is integrated with the SOPHOS Scan Engine to provide an e-mail gateway with a scanning mechanism for powerful scanning and virus code update features. It eliminates viruses upon identification of an infected mail. If the mail cannot be sanitized, Mail Sherlock will isolate it and notify the system manager. An infected mail will be isolated before they can enter the mail server. This protects the server and your PC from being infected.

Mail Sherlock is compatible with the existing AD (Active Directory) or LDAP Server in your system, to allow access to the unified account directory and easy management.

Message Reporting function integrates with the organization's internal short message systems (SMS) to send the various notifications.
