Some split-DNS domain names (hosted internaly with internal IP's and hosted externaly with public IP's)
Multiple public IP4 and IP6
SMTP > General > DNS server addresses: 220.127.116.11 & 18.104.22.168
SMTP > Inbound > Binding: one Public IP4 and one Public IP6
SMTP > Outbound > Binding: select one Public IP4 (why i can't select multiple IP's from diferent NIC and IP6?)
If MailEnable need to send mail to one of the split DNS domain names it resolves to the (internal) IP resolved from the internal hosted nameserver from a nameserver configured on the LAN-NIC (not resolved via the 22.214.171.124 or 126.96.36.199 nameservers so I got a external IP).
Because outbound binding is set to a fixed public IP from the WAN-NIC MailEnable can't contact the internal mailserver via LAN-NIC.
- Set Outbound IP to (default). But the side effect is mail will retouted out via a wrong WAN-IP so mail is tagged as SPAM due to misconfigured Reverse DNS etc.
- Edit host-file (currect situation). Not nice if i change IP-adresses I need to remember to change the host-file.
- How can I forse MailEnable to use the configured nameservers in de SMTP-General Tab?
- Can I (via Regedit) change the settings so i can configure for each NIC a specific outbound IP? So I can set for the WAN a single IP4 and IP6 address and for the LAN a single local IP4 address.
