Warning to those using cPanel

[thisisit3]

This is relevant to those using cPanel on dedicated or VPS systems:

cPanel has released version 11 to all cPanel releases EDGE/CURRENT/RELEASE/STABLE (stage 1) and by the end of september all releases will also include stage 2.

The above changes are major and mostly good, for example v11 uses 30% less memory and contains lots of new features that are very important.

One such change, is the new exim and spamassassin configuration. In v11 SA is executed via ACLs during the MTA procedure, when the email is still being uploaded by the client and if found to be spam the email is rejected right there.

This has the advantage of dropping the email at the MTA level before processing the email further, saves cpu usage, memory and other wasted resources.

Unfortunately, it also means that the SA headers are no longer used and exim is setup by cPanel to add its own headers (similar but not the same as SAs).

For example, instead of:

X-Spam-Checker-Version: SpamAssassin 3.2.2 (2007-07-23)
X-Spam-Level: *
X-Spam-Status: No, score=1.1 required=5.0 tests=BAYES_40,MIME_BASE64_TEXT,
 RDNS_NONE autolearn=no version=3.2.2

You get this:

X-Spam-Status: No, score=-1.1
X-Spam-Score: -10
X-Spam-Bar: -
X-Spam-Flag: NO

It may change by the time "state 2" is complete but you should be aware of the change because your filters will stop working.

one can still kick a flag in whm to get 11 to act the old slow way...

I have upgraded to the new cPanel version and it's really better like this! Better design, new feature and seems fastest than before!
