Setup my postfix server to relay

Hi all,
I'm trying set up my home sendmail server (VM) to connect to my postfix server (VPS) to send emails. I've set up my postfix server and its already sending and receiving emails (clamd, smtp auth, spamassasin, dovecot already setup)

HOME
sendmail server VM ------>INTERNET------>Postfix server------->

Can someone someone please help? THanks.

To do this, you will need to configure your home mail server's "smart host" in sendmail.

This will be done in your sendmail.cf file. Which on my CentOS server is /etc/mail/sendmail.cf, you may want to use locate or find to figure out where it is on your machine. One in that file, you will see a line that starts with DS. Modify this line to be DS and then the fully qualified domain name of your Postfix server

Example:

Code:

# "Smart" relay host (may be null)
DSsmtp.yourdomain.com
