Hello.

It seems that postfix (master) and spampd listen ton the same port 10025

ASUS-G75VW-JC:~ # lsof -i :10024
ASUS-G75VW-JC:~ # lsof -i :10025
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
master  3419 root   89u  IPv4  27075      0t0  TCP localhost.localdomain:10025 (LISTEN)
ASUS-G75VW-JC:~ # lsof -i :10026
ASUS-G75VW-JC:~ #

From /etc/master.cf

localhost:10025 inet   n       -       n       -       -       smtpd
  -o content_filter=
  -o smtpd_delay_reject=no
.....
.....
.....

From /etc/sysconfig/spampd

SPAMPD_OPTIONS="--host=localhost:10025 --relayhost=localhost:10026 --user=vscan --tagall --children=5 --maxsize=768 --homedir=/home/vscan"

Is it possible to change port number and what place is best ( master.cf or spampd.service )

May I make a bug report ?

Any help is welcome.

What is the guide you’re using to set up?
Pls provide an online reference if there is one.

The situation you’re describing might be considered expected if you simply installed common/default configurations because sometime postfix would be used by itself, other times with another app like spamassasin, and so postfix would be configured to communicate with other apps using the same ports.

I have nothing to provide.
This is initial config file ( /etc/master.cf, /etc/sysconfig/spampd ) and the two point to the same port number.
So I think it is a bad initial configuration.

But I don’t know if I may change one port number, and if I can choose any value.
