I have setup a DNS server outside the firewall that all websites point to from registrar. I then have all MX records pointing to one IP behind my firwall for six sites. This is an ISPConfig address. My question is: Can ISP Config be set up to deliver all mail, for multiple sites incoming on one IP, to each respected mail box? ie mail delivered to either [email protected] or [email protected] [email protected] web1_joe [email protected] Will I break ISPConfig if I do this above the line that says: #### MAKE MANUAL ENTRIES BELOW THIS LINE! #### What is the best way to handle this if it is possible. Many thanks for your help.
