Any idea how to BLOCK my vodafone mobile broadband connection from austomatically connecting to certain IPs (a list would be good as there are so many) that are on the Spamhaus block list for example http://www.spamhaus.org/query/bl?ip=212.183.140.50. These IPs are near impossible to use with most SMTP servers and make the service unesable for basic email Shame on Vodafone Tech Support for not clearing these up BTW.
