Version 5.1 Release Notes

New Features (5.1)

MTA Level IP Blocking

MTA level IP blocking rejects messages originating from IP addresses blacklisted by SophosLabs. Enabling this option can improve performance by blocking spam before it reaches more complex tests in the Policy such as the Sender Reputation (DNSBL) Anti-Spam tests.

Policy Level IP Blocking

The pmx_blocklist test is a policy-level implementation of IP blocking which uses the same data as MTA level IP blocking. It allows more flexibility in handling messages from blocked IP addresses and can provide more information about those messages in the logs. By using the IP addresses in the 'Received' headers, rather than just the connecting IP address, pmx_blocklist is effective even if the PureMessage server is one or more hops behind the network gateway.

Improved Internationalization

This release provides further enhancements related to internationalization, including improved handling of multi-byte characters.

Reports

In addition to multiple Reports bug fixes, this release includes an updated report on policy-level IP blocklist activity

Increased anti-spam updates

PureMessage 5.1 includes an increase in the frequency of anti-spam data updates to every 5 minutes
