    Redirecting packets to a virtual machine with iptables

    I had been running my SMTP server with WINE, as the SMTP server software is a Windows-based program (MERCURY), but I cracked the shits with WINE and removed it. Now I am running my SMTP server in a Windows virtual machine.

    This virtual machine has a different IP address from my host machine, so what I need is for my computer (the host) to redirect incoming traffic on port 25 to the virtual machine at on port 2525.

    Can someone please help me with it? I think its done with iptables.

    Your virtualizer (which one?) can probably portforward it.
    It also depends on how the VM network is defined: private, NAT or bridged.

    Other than that, your approach seems wrong.
    Apart from the problem with dns ptr,
    I think it is more straightforward to use a native unix smtp server such as sendmail, qmail, postfix, exim, etc
    You must always face the curtain with a bow.
