Hey all,

This is a two part question. For a while now I have been wanting to consolidate all my email on one server and then be able to browse the email via IMAP (all remote boxes are POP..yuck) I have fetchmail, postfix, and dovecotIMAP working just fine. My questions regard sending and recieving SMTP to the server directly. As I have it configured now, the client (my laptop) has an IMAP connection to my server. The laptop sends mail via my schools smtp server (idol). I have the relayhost=idol.union.edu variable set in main.cf. Does this mean that I can set my laptop to use my server as outbound smtp and it will relay it to idol?

(See my main.cf below)

In order for fetchmail to work I have opened port 25 on my firewall. Assuming that my school does not block port 25 incoming, how can I configure postfix to recieve incoming internet emails ? (I already have an entry in the school's DNS and static ip) Also, because 25 is open for fetchmail, how can i configure postfix to not accept outgoing smtp requests from the internet (i.e make sure the sever is secure) ?


Thanks for the help,

--Dave
