1.0.2 1.0.3 postfix fix not work

[andykimpe]

141.94.79.225 port 25

Code:

systemctl status postfix
● postfix.service - Postfix Mail Transport Agent
   Loaded: loaded (/lib/systemd/system/postfix.service; enabled; vendor preset: enabled)
   Active: active (exited) since Fri 2021-06-11 23:08:01 CEST; 1min 1s ago

Main PID: 6762 (code=exited, status=0/SUCCESS)

there are no firewalls

iptables -nvL

To fix this, I changed the postfix "master.cf": /etc/postfix/master.cf

Code:

# ==========================================================================
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)
# ==========================================================================
smtp inet n - y - - smtpd

I just changed the "y" to a "n", reboot the server (postfix reload didn't seem to work). I was then able to telnet to my server on port 25!

---

also port 25 maybe blocked by your provider maybe try 465

hi yes im just short coding stuff lol as mines on a virtual server for practice as i run windows so im just trying to follow it

---

yes i see its correct
 maybe you need to add it
/etc/sentora/configs/postfix/mynetworks  ?

Code:

# This specifies the list of subnets that Postfix considers as
# "trusted" SMTP clients that have more privileges than "strangers".
#
# In particular, "trusted" SMTP clients are allowed to relay mail
# through Postfix.
#
# Be sure to add your public ip address block if needed.

[andykimpe]

it is already present with the same content this file

[ccr1969]

well try different port see if it makes any difference as some providers block port 25

[andykimpe]

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

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

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

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

[andykimpe]

but you're stupid I told you who was to deactivate the firewall why you want to make me activate it you your although already in localhost it does not respond if it does not respond in localhost it cannot operate remotely

Code:

sudo ufw disable
sudo iptables -F
sudo iptables -X
sudo iptables -t nat -F
sudo iptables -t nat -X
sudo iptables -t mangle -F
sudo iptables -t mangle -X
sudo iptables -P INPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -P OUTPUT ACCEPT

and even with all the ports put in postfix it does not work then which returns active day on the status
