Ken:

The only blocklist I trust and I use is Spamcop. About your comments,
Spamcop has a good thing, it is that if you are listed, but your
machine stops sending spam, (stops being reported), you will be
automatically taken off in 24 or 48 hours.

I cannot stat how many SPF PASS make DNSBL in my system, because as I
told you SPF PASS I don't do any further check. As I commented above,
as I only receive 1 spam at a day, if I receive any from all my
accounts, I do go directly to the MTA logs and check what has
happened. 99% of the times the spam had not SPF records, did pass the
spamcop list, did pass the greylist retrying and even passed the
sender address check. What can you do about this spam? Just eat it
with some potatoes.  :-)

As I told you my sites are small. These are some statistics of my main machine.
