I’ve set up mail server as described here: how-to-configure-a-mail-server-using-postfix-dovecot-mysql-and-spamassasin, but I still can’t send email neither from my web-sites nor from CLI with simple echo 'This is a test' | mail -s 'test-out' command I’ve digged a lot, but still can’t find out where is the problem, any ideas?

Can you check if you’re able to connect to port 25 on remote servers?
