Hello
I have this situation:
Internet ISP #1
internet ISP #2
users goes out from ISP1 or ISP2 according to a mangle rule that matches an address list.
So:
Users ISP 1 and Users ISP 2.
OK.
the smtp relay server for isp 1 is: smtp-isp1.relay.com
the smtp relay server for isp 2 is: smtp-isp2.relay.com
I would like to do this:
I would lke to use in the user’s mail client, for example: SMTP.RELAY.COM that is a CNAME of smtp-isp1.relay.com.
But when the user using it is from users-isp2 address list, the MT should forward it to another host, smtp-isp2.relay.com
How can I use the Mikrotik reouter to “intercept” requests to that smtp service?
I think about something similar to transparent proxy
