Postfix not working on MacOS Yosemite [closed]
Postfix would not bind to the ipv6 port. Gives an error of:
*** postfix/master[39799]: fatal: bind fe80::1 port 25: Can't assign requested address
Solution 1:
I changed main.cf to bind to 127.0.0.1 instead of localhost
inet_interfaces = 127.0.0.1
Restarted postfix
$ sudo launchctl stop org.postfix.master
$ sudo launchctl start org.postfix.master
