postmaster bouncebacks due to misconfigured email servers

this isn’t essentially a win server subject, however I feel I’ve caught on to what lots of people from India are doing to get wealthy fast and do simple work as an try to acquire quick money.  see the picture for one thing I simply received from a postmaster characteristic of an email server which may fall into this class.  I despatched an automatic reply to somebody blasting out messages the world over, to anybody and everybody, and BCC’d many individuals inside the identical firm on it.  all BCCs have been bounced.  in accordance to the server error returned, one trigger may be what is known as a Mail loop.  right here is the descr from the server:



This error additionally signifies that the receiving group’s email settings are misconfigured, making a mail loop when a message is distributed to an handle that is not discovered of their listing. This often will not disrupt mail stream for recipients that really exist, however the recipient’s email admin ought to repair the misconfiguration to scale back the possibility of every other mail stream points. A standard trigger for this loop is that the recipient’s area is configured as “Internal Relay” when it ought to be “Authoritative.” Another widespread trigger for the loop is that each the sender and recipient are a part of the identical group, however the sender’s mailbox is hosted by Office 365, whereas the recipient’s mailbox is hosted on-premises, and an outbound connector from Office 365 to the on-premises email servers is lacking or misconfigured. To repair this, the recipient’s email admin ought to create a appropriately configured outbound connector in Office 365 to route the message to the on-premises mailbox.


as you’ll be able to see within the picture, it’s apparent that whoever despatched the message is utilizing workplace 365.  anybody utilizing it’s routinely assigned the suffix with their email prefix.  this postmaster message was despatched from [email protected] via, however the unique message was despatched from [email protected]


I’m pondering that is spot on.  anybody have any ideas on this?  as a comply with up that I’ve simply found, postmaster additionally bounces again all the identical addresses with the choice suffix!!  I feel that is a transparent indication of prison exercise, wouldn’t it not be?  that is the one factor that is sensible.  both that, or nobody at this firm is aware of how to click on a button and inform software program what to do!
