Yes, Dovecot is active (running), I’m not banned and if I take a:
telnet localhost 587
I receive:
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mail.coveriphone.eu ESMTP Postfix (Debian/GNU)
Dovecot is not the SMTP server and has nothing to do with sending mail.
# telnet mail.coveriphone.eu 25
Trying 75.119.152.130...
telnet: connect to address 75.119.152.130: Connection refused
# telnet mail.coveriphone.eu 587
Trying 75.119.152.130...
telnet: connect to address 75.119.152.130: Connection refused
localhost only proves the service is running, it does not prove anyone outside can connect. So, have you configured Postfix to not listen on public IPs? Is there a firewall? Does your host block mail ports?
Just getting the OP to check if the port is open to his connecting IP address, the OP states yhat connections on that port are refused
587 isn’t Dovecot, it’s Postfix. They may have problems with other mail-related ports, but Postfix is what handles receiving and sending mail via SMTP.
No, my firewall does not block connections on port 587, only when banned by Fail2ban.
I posted the Postfix configuration and I did not change anything except the domain and SSL.
