Received: from [213.167.166.26] (HELO thefreevirtual.org)
  by SMTP.az.net (Stalker SMTP Server 1.8b9d11)

Can I accept 213.167.166.26 as the real IP address of the offending MTA or is it like 
the HELO argument (thefreevirtual.org) which can be any durned thing the spammer 
pleases?

Trying to lookup the MX for thefreevirtual.org comes up empty which is why, I suppose, 
SIMS tries to connect to 61.129.78.34 -- the IP of thefreevirtual.org, which is 
probably not the real host name anyway.


00:17:33 3 SMTP-208(thefreevirtual.org) Failed to connect to [61.129.78.34:25]. 
reason=60

I went through the spam in the queue and noted that not more than three items were 
from any one IP address but all are obviously part of the same dictionary attack on 
one domain.

64.86.229.68
195.228.147.142
200.207.18.32
200.252.68.208
202.65.158.4
210.72.254.146
213.19.179.5
213.167.166.26
213.170.87.163
213.176.50.69
213.190.37.170
213.204.80.166
213.221.129.112
213.229.50.165

All gave the same "thefreevirtual.org" HELO argument.

Given the wide variety of addresses, is it likely that the IP is faked too?

Then again, those IPs that resolve are all non-US but scattered throughout br, de, it, 
at, etc. 

Now, I would think that a spammer with resources spread this widely would be caught by 
my RBL but that doesn't seem to be happening so I'm adding each IP manually in the 
hope that the IPs are not faked and that eventually it will do some good.

Am I wasting my time.
