We recently changed from an SBS 2003 to an SBS 2008 setup. In the process of migration, we have come across an issue whereby some users are receiving NDR emails when sending internal email.
IMCEAEX-_O=SAVEANDINVEST_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=David@sigrpglasgow.local #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
The issue is that the 'SAVEANDINVEST' text isthe old domain name, but the recipients text points to the new one (@sigrpglasgow). How do I resolve this?
