I was having a read of http://www.amset.info/exchange/dnsconfig.asp
and wondered what the expert community felt about this
I run Exchange with a Cisco FW infront. I currently have the FIXUP enabled for SMTP. Consequently the banner isn't as it should be. DNSREPORT advises me of this problem as well. Is this a serious issue? Will mail be rejected by picky hosts because of this?
