Oh, so if I am relying on remote mailservers being configured to resend after a temporary failure, how do I second guess the time intervals they are configured with? If they even resend at all?
Eg: lists.openbsd.org failed with default grey settings in spamd. I guess I don't have the skills to run a greytrappin spamd, and still receive the mails I want to receive, and ought to run in blacklist mode instead ;-) On Fri, May 25, 2012 at 02:03:03AM -0500, Matthew Weigel wrote: > On 25.05.2012 01:09, David Diggles wrote: > >Can messages get dropped if mail servers fail to resend within > >time interval, after receiving the initial temporary failure message? > > A qualified "yes."
