I keep doing this:
1. Install Debian 12
2. # apt install postfix
3. Edit /etc/aliases to say "abc: xyz@gmail.com"
4. # newaliases
5. Restart Postfix (sometimes even reboot the Debian server)
This is a complete out-of-the-box install with Step 3 being the only modification. I'm missing something somewhere because it never forwards to the alias nor recieve mail in abc's local inbox.
What am I missing between steps 2-5?
