1.0.2 1.0.3 postfix fix not work

[ccr1969]

it is not the case of the supplier it is ovh

ovh does not block port 25 it name never made its in 20 years

it's not now that we start

---

moreover it is a problem of blocking of port even locally it not responds

Code:

telnet localhost 25
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

i can ping 141.94.79.225
but connection is refused on 141.94.79.225:25
open on port 22
if i telnet 110 i get +OK Dovecot (Ubuntu) ready.
143 * OK Waiting for authentication process to respond..
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot (Ubuntu) ready.





but 25 467 587 cant connect refusal so ports closed

---

sudo ufw allow 465/tcp
sudo ufw allow 25/tcp
sudo ufw allow 587/tcp

---

220 test-server ESMTP
thats what i get when i telnet my test server

---

try this put in master.cnf
smtp inet n - n - - smtpd
25 inet n - n - - smtpd
587 inet n - n - - smtpd
465 inet n - n - - smtpd
then run the following commands :

service postfix reload

service postfix restart

---

netstat -plutn | grep 465
netstat -plutn | grep 25
netstat -plutn | grep 587

root@test-server:~# netstat -plutn | grep 587
tcp 0 0 0.0.0.0:587 0.0.0.0:* LISTEN 1836/master
tcp6 0 0 :::587 :::* LISTEN 1836/master
root@test-server:~# netstat -plutn | grep 465

tcp6 0 0 :::25 :::* LISTEN 1836/master

i didn't have listening ports till i added them in master.cnf
