Sendmail Mail Routing
So i have sendmail running kind of and want to do the following.
I was looking around for mail routing tutorials/howtos but all i was getting was bits and bobs so if anyone can clear this up for me I would be really happy or point me in the right direction.
I have 2 servers and i want all the mail to come into 1st server then want it to forward a copy onto server 2 so that i can setup pop3 on server1 and imap on server2.
Server1 = pop3, receives all email
Server2 = imap, receives a copy threw mail routing
I know this is not the common practise but am mainly doing it to learn how mail routing works.
