Be very careful which blacklists you use. Most are utter rubbish and don't check what they list or offer enough information to actually be able to get support staff of the listed ISP to fix the problem. It's very annoying getting bounced because some over-zealous blacklist decided to include the whole hosting provider/hosting facility/ISP/uplink/country/world after one email to a honeypot address from a clueless person's web form or autoreply.
You are not dependant on your isp's mail relay, Anybody here who is on Demon for example can verify how annoying it is to have delayed or lost mail as a result of your ISP's SMTP service not responding in a timely fashion.
Increasingly, UK providers seem to be silently junking email and a few (BT-Yahoo, Demon and Frees^WWannad^WFrance Telecom, I'm looking at you) seem to be getting it very wrong occasionally.
