I'd like to know if the following scenario is possible:
- 1 Zimbra server
- 1 DNS server
- 2 internet connections from different providers both with static ip addresses
What I want to do:
- All outgoing SMTP traffic goes out using Provider1 link
- All incoming SMTP traffic is received using Provider2 link
What I thought was:
To have two MX records in our DNS server:
Provider2. 60 MX 10
Provider1. 60 MX 20
My intention is to force incoming smtp traffic through Provider2 by setting the MX record with the highest priority (10).
For the outgoing traffic I can force it to use Provider1 by setting this in my firewall.
Is this possible?
