Clearswift has upgraded its MIMEsweeper for SMTP gateway software to include new message tracking features and spoofing protection.

MIMEsweeper for SMTP 5.2, available now, can consolidate e-mail stats instead of just transaction-level details, and companies can store or export messages and run reports based on this information.

A new validation feature allows LDAP address lists to describe valid e-mail addresses within a company. And there is new protection that prevents e-mail address hijacking - spammers often attempt to discover valid e-mail addresses by bombarding a mail server with potential usernames to discover which are valid.

MIMEsweeper for SMTP 5.2 is priced based on the number of users. For a company of 500, it will cost $8,030, plus $2,008 for support per year.
