1. linux machine is the primary domain server for domain.com
2. connection to ISP B is dedicated dial-up
3. connection to ISP A is via leased line and this is the default route.
4. wingate has SMTP Mapping service.
linux.domain.com. IN A x.x.x.2
wingate.domain.com. IN A y.y.y.x
domain.com. IN MX 10 linux.domain.com.
domain.com. IN MX 20 wingate.domain.com.
if i set the 2 machines as mail exchangers for domain.com, would
incoming emails pass through the wingate machine if my link to ISP A goes down
?
can MX do that ?
thanks in advance.
