spamcop has a reputation of being somewhat aggressive on blocking,
and their website recommends using it in a scoring system (eg.
SpamAssassin) rather than for outright blocking.  That said, many
folks (including me) use it anyway and find it acceptable.

See the spamcop website for details, and make your own choice.

list.dsbl.org is no longer active.  Remove this line.

The spamhaus lists are now consolidated in zen.spamhaus.org, replace
the above two lines.  See the spamhaus web site for details.

This one is OK.  Again, you should check their website and review
their published listing policy to see if this is something you want
to block. 

Blocking mail is a very site-specific choice.  Use the advice you
get as a starting point and make your own decision about how
aggressive you want to be.
