Ebay, St Helens Community Federal Credit Union, ... Question I have, why aren't these email sources reverse resolvable?
How on Earth am I supposed to detect that a mail host is a random infected personal computer instead of some domain's legitimate email server? Should I go ahead and block if there's no reverse PTR record? Short of saying there is a resolution problem and requiring that another message be sent with a secret I provide for white listing purposes, what can I do? Since I have the email connection request packet in user space, can I do something to the packet to cause Postfix later to bounce it? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
