I currently administor an Exchange 2003 server using our .com extension and i want to setup a fedora box as an email server with either an addition to the .com extension or with a .net/.org extension. My question is how exactly do i make these 2 mail servers coexist on the same network without any problems? do i have to use different ports for pop3/imap/smtp or can i use the same ports for both? what kind of pointers must i have for DNS? Any answers will be greatly appreciated. Thanks in advance!
