Barracuda Networks Spam Firewall

Here's what I got today from Barracuda.  I'll let you know if it did
indeed fix my problems.

Hi Joe,

Your latency problem should be resolved.

=======================================================
On July 27th a new stream of spam was introduced into the wild. This
spam contained certain formatting
aspects that were intentionally designed to cause Spam Assassin's
Bayesian implementation to run at
extremely slow speeds. Due to the way Spam Assassin handled the email,
it was taking several minutes to
process these messages and the Barracuda's internal processes would
detect the potential problem and start
queuing mail to prevent any mail loss. Unfortunately this precaution
had the byproduct of further
increasing the message latency on the system.

Barracuda Networks' team of engineers created a patch for this Spam
Assassin attack. The patch was
released in version 1.6.733 of the spam definitions. If you were
affected by the new spam, please make
sure you are running this version or higher of the spam definitions
(Advanced->Energize Updates in the web
GUI). Also, if you had previously contacted tech support and were
advised to disable Intention Analysis
(Basic->Bayesian/Fingerprinting) as a way to attempt to reduce
latency, you should be able to turn this
feature back on without any issues.

=======================================================

Let me know if you have any additional concerns.

Heather
