Bot spam increasing?

[Marc Perkel <ma...@perkel.com>]

Has anyone else noticed an increase in bot spam? My black list has grown 
by about 1/3 in the last month.

Yes, I just checked the numbers for the last few weeks.  Volume was in 
line with the weekly average for March through two weeks ago, last week 
shows a 55% increase over the March levels, and this week is above 96% 
already with two days to go before a log rotation.  Nearly all of it is 
coming from the typical set of compromised machines.

Does this actually amount to anything more than a curiosity?  From my 
perspective, it's just more of the same.  For what it's worth, the SA 
numbers haven't changed significantly -- it's not even getting a crack at 
this latest spate, the SMTP checks are doing the job.

We have seen an increase of over 50% in spam volume this month.  A lot of it 
does seem to be coming from bots.
