Internal Domain and Netbios name in email header.
Posted on 2008-11-13
Im running Exchange 2k7EE SP1 with hotfix rollup 4 on Server 2008EE. Although Im not having any issues sending or receiving mail, my header seem to be incorrect (not sure) as my internal mailservers name and domain (.local) is shown in the header. I know for a fact when running exchange 2000, my internal name/domain was never listed. But the thing is, SPF passes when sending to my gmail account. Attached is my header. At this point, I have no reports of failed sent message. But this header really concerns me. Is this wrong or is it ok?
INTERNALDOMAIN= my internal domain name...... ie mydomain.local
NETBIOSNAME= the internal name of my compter when installing windows ie. server1
xx.xx.xx.xx = My EXTERNALIP address on my Firewall which NATs to my mail server.
