I don't know what the prevailing attitude is, but it seems to me that 451ing unknown senders is a good way to get on the bad side of sysadmins who have to deal with the backlog until your server decides to accept them. I would think if you're willing to spend other's resources on reducing your spam load you would be willing to spend your own and implement SMTP callback, SPF or the like. I tried implementing SPF which actually caught a fair # of forged senders until I noticed that ticketmaster had invalid SPF records and we were rejecting their emails. -S On Wed, 3 Mar 2004, Nathan Allen Stratton wrote:
