I've just received this response from a large corporate email system regarding their claim that emails sent to them are not getting through even though our logs contain acknowledgements of accepting the mail sent.
In our mail logs: ... status=sent (250 Message accepted for delivery) Their response: ... "my understanding of the <firmname removed> security policy is not to acknowledge mistakes in email addresses as a best practice defense against phishing and other types of email delivered attacks." Anybody run into this kind of logic before? -- John Brooks j...@day-light.com
