When I attempted to send emails later from that corporate email address, I received a mail from ‘System Adminstrator informing me that ‘Your message did not reach some or all of the intended recipients.’ and at the end of the notification was attached the cryptic diagnosis ‘554 Remote recipients limited.’ I noticed that the intended recipients were rather randomly distributed over several industries or even private persons, none of whom exists in my address list, and I promptly deleted all those mails from both my Outlook folder and my folder on my corporate server. Just today I noticed wom very worrying behaviour on my corporate mail server: As I logged on via Outlook Express I received a slew of bounced ‘undeliverable’ emails. So the mail server responded back with a 554 Invalid recipient error. In our example bounce-back error above the reason the message has failed is because an auto-reply was trying to be sent to an account that didn’t exist. To better understand soft and hard bounces, and general email bounceback errors you can read why does email bounce, bounceback, or error?
