For the record, I agree.  I wasn't advocating not continuing to use 
MailScanner.  I would never do that.  I was merely pointing out the 
effectiveness and performance of BarricadeMX.  I was also not commenting 
one way or the other on the benefits of using other techniques in front 
of MailScanner.  Certainly there are effective ways of doing that. 


And, my systems were not all that unprotected!  I did use RBLs at the 
MTA and milter-limit and milter-null plus MailScanner/SA.  It was 
detecting about 90% of the total inbound messages as spam.  I did have a 
big problem with overloaded systems however.  When that happens there's 
only two possible ways of dealing with it -- more hardware or more 
software (or both).  I chose software -- BarricadeMX.  I think it was a 
good choice for me.


And lastly, I wasn't spamming the list at all.  The product was first 
announced on this list by the list's owner.  That's how I found out 
about it.  Giving a report on implementation of a product that was 
announced here is certainly within the purview of this group.  More 
information about effective anti-spam techniques in combination with MS 
is good, right?
