If you have to go through one 4xx messages to send a message then it takes twice the network bandwidth to send a spam and more than twice the effort (queues have to be maintained etc). If you were to require more than one 4xx message and a longer time-out then it makes it even more work for the spamming machine and thus reduces the volume of spam that can be sent before the machine is put on black-lists and/or shut down. There is no solution, there are just many ways of alleviating the problem for us while making more problems for spammers. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
