Re: CSF blocking MX with Port Scanning

Do you suggest to change back the "0:24,26:65535,ICMP" to "0:65535,ICMP".

I'll check the sysctl net.netfilter.nf_conntrack_max en sysctl net.netfilter.nf_conntrack_count if you think this might cause the issue. Will report back when I find out how to show them on my old CentOS 5

Re: CSF blocking MX with Port Scanning

ah, nice it seems all gmail mails now get in my inbox (gmail just needed a hour or so), even mails i send yesterday to my email account show up. I hope the same happends to other emails for other providers (that they still get the mails from yesterday) Sure this isn't a bug from the updater? I never...

Re: CSF blocking MX with Port Scanning

I want to say I had exactly the same issue after the update, but I noticed rather late (today)... so gmail was blocked and many other email providers. I just changed all and deleted the blocked IP's but I'm very afraid gmail blocked my email server now as test are not working well to gmail so far.
