Howdy, we installed a new SBS2003 server over the weekend and everything seems to have going great, until a user brought to my attention that as he sends internal mail its boucing back with the following error:
The message could not be delivered because the recipient's destination email system is unknown or invalid. and give the error #5.1.2
Is this DNS...We may need a reverse lookup?
I do notice that each box that is boucing has not been logged into yet.
Any ideas?
Thank you!
