Posted on 2004-09-01
I have taken over a site that has SBS2000. All is cool except the email.
SBS Domain is registered as dandl.co.uk, but the exchange 2000 users have had firstname.lastname@example.org manually added.
If I try to send mail to the email@example.com, I get......................
xx.xx.xx.xx does not like recipient.
Remote host said: 550 5.7.1 Unable to relay for
Giving up on xx.xx.xx.xx.
Im getting nowhere very fast as I have checked that the administrator has this mail address in the list and is is set as primary.
