Subject: Re: firewalld
firewalld isn't the only thing that will prevent services from accessing the
internet. I found that I needed to do a relabel before postfix could access
DNS and I have seen other issues as well. Have you tried disabling the
firewall to see if you can get connections to work? Then try to disable
SElinux and see if that works.
# netstat --inet -l -n
Is the service listening on port 143?
# systemctl stop firewalld
Does it now work?
# setenforce 0
Does it now work?
Once you establish what's biting you then you can fix it. To force a relabel
do
# touch /.autorelabel
# reboot
Mike
I have dovecot answering now. I can read mail using Mutt.
I think I have problems with mysql/mariadb using roundcube. It may be I need
to open ports for mariadb as well.
Thanks
