Exactly, the number is huge.  It’s up to 95K now!  Yeah, I also checked IP 
addresses and there doesn’t seem to be any commonality between them but I’ll 
keep checking.  Pulling my hair out indeed.

The Barracuda device is SPAM filter, as well as virus protection, spyware, and 
content filtering.  He want's to know if he is specifically being attacked.

 

80k e-mails for 250 e-mail addresses in 15 hours is huge.  Being that they are 
all blank seems a little odd. Not your typical spam I'd say, and I've not heard 
of this happening to anyone.  I have noticed a very small number of e-mails 
lately they had blank subject AND sender. First time I noticed them so it's 
something new.  But not in that volume.

Are you running any type of Spam software on your network?  If not, I’d start 
off by purchasing one.  We use GFI and are quite impressed by it as it works 
with AD.

We recently got a Barracuda Box (which is great by the way), and are using it 
as our SMTP smart host relay for incoming and outgoing mail from and to the 
outside world, respectively.  We are getting hit with a HUGE amount of messages 
that are just empty (no TO:, no SUBJECT:, no FROM:, nothing)  To give you an 
idea of just how many we are getting, we have 250 users and since I set up the 
new spam box last night (15 hours ago), we have received over 80,000 messages!  
Most of which were blocked…  My question is – Is this some sort of continued 
attack our domain is under?  If so, what steps can I take to help fix, or slow 
down, this problem? 

 

ANY Advice at all would be greatly appreciated as this stuff is killing us!!!
