sorry for this generic mail system question i've got a problem with hotmail; when i send mail to a particular domain ( example.com) sometimes it bounce back saying :
This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed. a...@example.com Final-Recipient: rfc822;a...@example.com <rfc822%3...@example.com> Action: failed Status: 5.7.1 Diagnostic-Code: smtp;554 5.7.1 <a...@example.com>: Recipient address rejected: Access denied it's not even reaching the recipient's mx but sometimes it get delivered; the problem started very recently; any clue about this! appreciate some guidance -bharathan
