How to remove postfix warning?

Serhii_Yaholnyt — Thu, 05 Jul 2018 14:46:03 GMT

We had to change our hostname in SMPT header, so we used sk101870. After installing policy when we are looking at postfix queue with command "[Expert@HostName:0]# /opt/postfix/usr/sbin/postqueue -c /opt/postfix/etc/postfix/ -p", we have a warning: "Jul 3 17:59:53 2018 TEST-HOST postfix/smtpd[6608]: warning: /opt/postfix/CTX/CTX00003/etc/postfix/main.cf, line 55: overriding earlier entry: myhostname=TEST-HOST". We can see multiple records "myhostname=..." in file /opt/postfix/CTX/CTX00003/etc/postfix/main.cf. If we would remove and leave only one, the problem is gone. But these records are recreated every time we install policy. Is there any way to remove them permanently or make that warning not appear?

I know that we can redirect STDERR to /dev/null but I am looking for possibility to remove it permanently.

Is it the same entry multiple times in the file?

That sounds like a bug and I would recommend consulting with the TAC: Contact Support | Check Point Software

/opt/postfix/usr/sbin/postqueue -c /opt/postfix/etc/postfix/ -p 2>/dev/null‍

Did you ever find a solution? I'm seeing a similar error below, however, the config_directory line only appears once in main.cf

warning: /opt/postfix/etc/postfix//main.cf, line 679: overriding earlier entry: config_directory=/opt/postfix/etc/postfix/

[Expert@FW:0]# cat -n /opt/postfix/etc/postfix/main.cf | grep config_directory
280 #mynetworks = $config_directory/mynetworks
623 # >$config_directory/$process_name.$process_id.log & sleep 5
679 config_directory = /opt/postfix/etc/postfix

Came across this post after I had a similar issue tonight. I found that CP documentation often leaves the trailing slash in the -c switch of the postqueue command, like this:

/opt/postfix/usr/sbin/postqueue -c /opt/postfix/etc/postfix/ -p

However, by default, the config_directory parameter in the postfix config file omits that trailing slash:

config_directory = /opt/postfix/etc/postfix

I think the warning is pointing out the mismatch between what's in the command (a slash) and the config file itself (no slash). I've found that if I run the postqueue command without the trailing slash, I don't get the warning in my output, which makes it much easier to parse out single values. This came in very handy when trying to tweak the suggested script in the Threat Emulation ATRG for monitoring the MTA queue:

#!/bin/bash # Extract Postfix queue size value MAILQ=$(/opt/postfix/usr/sbin/postqueue -c /opt/postfix/etc/postfix/ -p | egrep '^--.*Request|^Mail.*empty') if [[ $MAILQ =~ "empty" ]] ; then RESPONSE=0 echo $RESPONSE elif [[ $MAILQ =~ "Request" ]] ; then RESPONSE=$(echo $MAILQ|awk '{print $5}') echo $RESPONSE else RESPONSE=error fi

With the trailing slash left in the script, I would get that warning, which would introduce additional output. Taking out the trailing switch left me with just the number I wanted.
