Using the above example, just pipe it through wc (word count):

	grep spamhaus /var/log/maillog | wc -l

and that will tell you how many lines contain that string. To check all of 
them at once, you can use a regex and do something like:

	grep [spamhaus|dnsbl|foo|bar] /var/log/maillog | wc -l

and that will give you the total of all rejected messages (assuming you put 
all your DNSBL names in the [...] above. It won't tell you how many are being 
blocked by each one though.
