Cambridge Mail Server: Exim 4.70 Provides Better Spam Protection
Exim 4.70, a mail server developed at the University of Cambridge, combines new features and bugfixes.
The new Exim server provides native support of DomainKeys Identified Mail (DKIM), so as no longer to depend on external libraries. DomainKeys are cryptographic extensions for mail headers that confirm the domain source for messages. DKIM should help fight spam and phishing attempts.
A further Exim feature is support for Distributed Checksum Clearinghouses (DCC), a system that checks well-known spams against their checksums, albeit the feature being still in an experimental stage.
Developers also removed the embedded library for Perl Compatible Regular Expressions (PCRE) from the server, because most operating systems provide their own library for the purpose. The project changelog also lists a slew of fixed bugs.
Exim 4.70 source code is available for download as an RPM package from the project homepage. The license is GPL.
