Don't just tell us. SHOW us.
unicorn:~$ sudo lsof -i :1812
[sudo] password for greg:
unicorn:~$
If there's something using that port, lsof will show it:
unicorn:~$ sudo lsof -i :25

STOP that!!
DO NOT use kill -9 unless it's ABSOLUTELY necessary! Even if you think it's
absolutely necessary, consider rebooting instead. You might have to anyway, if
some process is stuck on a hardware failure.

Sure sounds like something is using the port. lsof should show it. Or ss, or
netstat, if you use them correctly.
unicorn:~$ ss -ntl | grep :25
LISTEN 0 20 0.0.0.0:25 0.0.0.0:*
unicorn:~$ sudo ss -ntlp | grep :25
LISTEN 0 20 0.0.0.0:25 0.0.0.0:*
users:(("tcpserver",pid=657,fd=3))
(The -p option requires superuser privs.)
