I really need a frontend due to the volume of crap that is being
attempted here. Then you have it's virus & spam engines along with
Barracuda's intent database(a database of 'bad' urls to block).
Everything I have read is that the barracuda's spam filtering is based
on SpamAssassin, but our primary mail server(not Surge yet) running the
latest and greatest SA catches a bit more spam after the the barracuda
scans it. The same with using ClamAV on the mail server, now you have
a second layer of scanning with a different scan engine. One content
scanning engine and one AV engine is just not enough any more, IMHO. ;
I still see ClamAV catching a few virus/trojans early in the cycle of a
new bad one, like in October. Because the Barracuda is first, I cann't
say for sure if it catches some things earlier than ClamAV or not.
I did have the chance to compare McAfee against ClamAV. ClamAV was
doing as well and sometimes better than McAfee at getting updates out,
but that was when McAfee was in the process of outsourcing their ftp
services. But all in all, it appeared that having multiple AV engines
was a good thing.
It's not unusual to see over 60,000 attempts in 24 hours (and climbing)
right now with less than 10% (on weekdays, worse on weekends) being
passed on to the mail servers. I just feel a front end is needed here
to let the mail server handle what it should, legit email and end user
traffic, plus the extra layer of scanning with different engines.
As we move towards Surgemail for our primary email server, I expect
that I will leverage it's spam filtering to cut out more crap. ; Things
are progressing and I expect to start migrating domains in a month or
two to our Surge setup(running a mirrored pair behind a NAT doing port
forwarding) and by then we will have had our Barracuda for a year
already.

provide until the Barracuda is replaced.
What does a Barracude do that Surgemail doesn't?
