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!
