Version 5.1.1 Release Notes

New Features (5.1.1)

True File Type Detection

Policy attachment tests (pmx_attachment_name, pmx_attachment_type, and pmx_suspect_attachment) now have a ':tft' option for determining the true file type of an attachment. The file itself is inspected rather than trusting the filename extension or MIME type in the Content-Disposition and Content-Type headers. (Extended Policy Module)

Add Banner to Top of Message Body

The pmx_add_banner policy test now has the ability add a banner to the top of a message body using the ':top' option. (Extended Policy Module)

%%ATTACHMENT_NAMES%% Template Variable

A new template variable for attachment names can be used in notifications or banners.

Rename Attachment

A new policy action, pmx_rename_attachment, can be used to rename attachments using the %%ATTACHMENT_NAME%% template variable. (Extended Policy Module)

Multi-Byte Character Sets in Banners

The pmx_add_banner policy test now supports adding banners in Asian language character sets.

New Anti-Spam Engine

Includes a new feature for detecting phone numbers or instant messaging IDs contained in spam messages, as well as other improvements.

pg_autovacuum

The pg_autovacuum daemon (run by PostgreSQL) replaces the vacuum_db scheduled job. This daemon optimizes the PostgreSQL database every 5 minutes.

TLS Support

Transport Layer Security (TLS) support has been added to PureMessage-Sendmail and PureMessage-Postfix.

Additional OS Version Support

FreeBSD 5.3 and 5.4, and Debian 3.1 are now supported.

Bug Fixes (5.1.1)

• Milters no longer load blocklist data if pmx_blocklist is not used in the policy. (#42240)
• A fix for a problem causing excessive memory usage by pmx-milter processes when loading blocklist data. Memory used for blocklist data is now shared between all milter processes. (#42234)
• Reporting now distinguishes between servers with the same hostname. When viewing reports on specific servers the fully-qualified hostname is displayed instead of only the hostname. (#40505)
• An increase in the frequency of anti-virus update checks (every 5 minutes).
• Sendmail configurations with MAIL_HUB enabled now correctly obeys requests from pmx-milter to delete recipients. (#40442)
• A problem with missing data in the Top Releasers and Number of Releases reports in Central Server Manager deployments has been fixed. (#41163)
• Messages exceeding certain size and header count limits no longer cause MESSAGE EXCEPTION failures in pmx-milter. These messages are now quarantined rather than being tempfailed. (#41516)
• The known issue with the oshealth_on_fours and oshealth_on_nines scheduled jobs leaving orphaned processes has been fixed. (#40922)
• Various other fixes and improvements.
