I have an email server hosting two email domains e.g. @sisco.com and @neatco.com each resolved to two different public IPs (MX records etc)
I have a Cisco 5510 ASA firewall at my perimter and now I have the challenge of mapping the two public IPs to my mail server on the internal side.
How can I over come this without having to give the server two separate private IPs for each email domain???
