Hi,
It's been a while since I seek why it does not work, but still nothin, so I come to ask your help please.
Currently I can send email internally and externally.
But impossible to receive from the outside, I get that error on Edge :
exchange.internal.domain / SmartHostConnectorDelivery / Error 451 DNS Query Failed. SMTPSEND.DNS.NonExistentDomain; nonexistantdomain
Here are my configurations
- AD local only
- Exchange
ETH0: lan (dns to AD)
ETH1: wan (dns 8.8.8.8)
- Edge Transport
ETH0: lan (dns to AD)
ETH1: wan (dns 8.8.8.8)
HOSTS File + (+ exchange.local.domain exchange host)
Test-Sync status: Normal
EAC configurations
Server / Mailbox / DNS Lookup:
- WAN: external network adapter DNS 8.8.8.8 +
- Local: + DNS internal network adapter "AD IP"
- Type Certificate UCC installed (if it can change something?)
Mail Flow:
- Sent EdgeSync Connector Default: MX + server use external DNS
On the local DNS server (AD), with or without forward to 8.8.8.8 does not change anything.
What did I forget?
Thanks for your help
