External Address Verification. IMail customers with an Unlimited User License now have the option to add External Address Verification (EAV), allowing IMail to be used as a gateway for an internal server. With the addition of EAV, mail recipients can be verified via LDAP or Active Directory as valid users on the internal server before the message is accepted.

New Realtime Whitelists. Realtime whitelists are databases that store IP address and domain names of trusted sources. Messages that are matched to a Realtime Whitelist will be considered as trusted and will bypass further validation checks as set by the system administrator.

New Mailbox Size Report. This new reporting feature allows administrators to view the total mailbox size of each user on a domain.

New Performance Counters. IMail now has new IMail Performance Objects used by “Perfmon” to report daily spam and viruses caught as well as open SMTP sessions.

New Account Harvesting Prevention on POP3 and IMAP. This tool allows administrators to prevent malicious attempts by a client from continually trying to log in and gain access to usernames and passwords.

New Web Client Password Strength Validation. This new validity check on the web client now enforces the password strength requirements set by the administrator. Users who do not meet the password strength requirements will be prompted to change their password upon login.

Updated Daily Report Email: The daily report email now includes information on licensing and spam and viruses tagged by Commtouch’s Anti-spam and Anti-virus offerings.

Updated SSL Configuration Utility. The private key size for a SSL Certificate is now configurable, allowing the administrator to assign the default certificate a higher security level.

Updated Ipswitch Instant Messenger Client. Fixes and enhancements are as follows:

  • Warning added when a new conversation is initiated with multiple recipients
  • Capability to start new conversations with the same recipient in multiple conversation windows
  • Conversation bar now displays a count of all recipients
