A way around these problems may be to use your ISP's mail-relay, rather 
than delivering directly.  Or use a third-party mailer, such as fastmail.fm.

Usually your ISP is not on any black-lists, and they also (should) have 
mechanisms in place to get off such black-lists when they get on them.

Of course, to get lots of messages out via your ISP you may need to 
authenticate your connections and so on - I ended up building a custom 
version or postfix to use SASL and TLS, with which my ISP let's me 
specify 300 recipients rather than 50.  Telling postfix 
"default_destination_recipient_limit=300" completed the magic.
