Hi. I setup postfix on my Ubuntu 18.0.4 by some tutorials. It sends mails to other boxes(like my email on gmail). I already get certificate and configurate tls. But I can not receive any email. Postfix is listening 25 port.

master     9680            root   13u  IPv4 250327773      0t0  TCP localhost:25 (LISTEN)
master     9680            root   14u  IPv6 250327774      0t0  TCP ip6-localhost:25 (LISTEN)
master     9680            root   18u  IPv4 250327779      0t0  TCP localhost:587 (LISTEN)
master     9680            root   19u  IPv6 250327780      0t0  TCP ip6-localhost:587 (LISTEN)

also my ufw status :

ufw status
Status: inactive

But when I scan my 25 port by scan service like this https://www.ipvoid.com/port-scan/ or from my home PC - it teels :

WARNING: TCP connect to (myipaddress : 25) failed  

Can anybody help me with my problem? /var/log/mail.log tells nothing about incoming messages. Thanks!
