I was going through my log files finishing up a new installation of ISPConfig 3.03 when I discovered this one showing up in my Mail Warn-Log every time I rebooted the server:
linux spamd: dns: sendto() failed: Operation not permitted at /usr/share/perl5/Mail/SpamAssassin/DnsResolver.pm line 395.
I looked at other posts in the forum and discovered that others have had this problem and the recommended solution was to run through this tutorial:
I did that. I verified that fail2ban is no longer writing to iptables. I turned back on the firewall and rebooted.
Same error message.
Since fail2ban is not the culprit, is there a conflict between SpamAssassin and ISPConfig's firewall?
