I dimly remember that I had the same problem with Pipex and a few places in the US as well. I ended up whitelisting /24s as they came by. What bothers me more is that, at least until very recently, some moderately well-known outfit over here, who claims to do "unified messaging" and sells application hosting, esp. email, bounced messages upon 4xx without retrying at all. :( -- Kind regards, --Toni++
