Check, that you don't have 2 amavisd.conf - files in 2 locations. From time to time there are some problems wiith centos as they changed the location for the amavis-config but did not remove the old file.

 

@Jesse Norell : Thanks for the suggestions, my disk is not full and how can I check my disk is readonly or others? (sorry for being noob)

@florian030 : which amavisd.conf should I remove?

Code:

[root@svr ~]# locate amavisd.conf
/etc/amavisd/amavisd.conf
/etc/amavisd/amavisd.conf~
/etc/clamd.d/amavisd.conf
/usr/share/doc/amavisd-new-2.10.1/amavisd.conf-default
[root@svr ~]# systemctl status amavisd.service

Do you have a /etc/amavis/conf.d/50-user ? In this case rename /etc/amavisd/amavisd.conf and use reconfigure ispconfig (php -q update.php)

 

thanks for the update

Sorry, there is no /etc/amavis/conf.d/50-user on my server, and actually /etc/amavis folder is not exist as well.
Should I proceed to reconfigure ispconfig (php -q update.php) ?

Code:

[root@svr ~]# locate 50-user
/etc/fonts/conf.d/50-user.conf
/usr/share/fontconfig/conf.avail/50-user.conf

 

thanks for the update

I got this message

Code:

[root@svr ~]# awk '$4~/(^|,)ro($|,)/' /proc/mounts
tmpfs /sys/fs/cgroup tmpfs ro,nosuid,nodev,noexec,mode=755 0 0

 

so

sorry i have 50-user how do i rename
