Hi,

Just debugged some extreem errors.
When you install nginx with modsecurity with the default settings nginx become a memory hog (Took 3.1Gb memory instead of 60Mb).
Opening custom httpd configuration took 5-10 seconds while without it is less then a second.

https://developers.google.com/speed/pagespeed/insights/
gave a 20% lesser score.

Restarting nginx took 10-15 seconds while without it is in about 1-2 seconds.

Same user account, for one domain (bbbbb.nl) the DKIM is generated, for aaaaa.nl nothing happens?

If you check letsencrypt.sh you can see it determines if it is a request for the server hostname like this:
1. The domain must not be in /etc/virtual/domainowners
2. The domain must be in /etc/virtual/domains
3. The output of "/usr/local/directadmin/directadmin c | grep serveame" must match the domain you are requesting it for.

if the certificate you are requesting matches this it'll be treated as a cert for the hostname.

The letsencrypt.sh script will create the san config if it does not yet exist, so you should be able to move it just fine and then request the cert, granted other conditions are met. It's simply re-using the existing SAN, but removing (or editing) it shouldn't matter.

Report that the RBL combined.rbl.msrbl.net has stopped working.
Removed from all exim.conf versions.

The update is now on files1 and files2. To get the update, use CustomBuild 2.0:

cd /usr/local/directadmin/custombuild
./build update
./build exim_conf

Related if using older CustomBuild with exim.conf 4.x:
https://help.directadmin.com/item.php?id=51

Other solutions are to manually remove the combined.rbl.msrbl.net line from your /etc/exim.conf RBL_DNS_LIST entry.

Note, SpamBlocker 2.x versions are not affected, as they were not using this RBL.

Is it possible for mirrors to sync multiple times a day? I use files6 and that mirror only syncs one time every day (10:00). For normal updates it's fine but for example with the pulled PHP 7.0.20 update or the exim.conf 4.5.5 update (not working RBL) it would be nice if updates came a lot quicker

For one of our customers we needed to let a company perform a 'penetration' test on the website on our managed VPS. We have done this before but never any major problems. In this case it wears out the server. The server load spikes to around 35. Since there is a production website of the customer on that VPS we complained to the company performing the penetration test because the website went very slow/offline. They say their test should not be that heavy and something is wrong with the vps. Specs of the VPS:

CentOS7 + Directadmin + fail2ban + CSF
2 CPU - 4GB memory
low on traffic]
Normal average load around 0.4, when test is running between 30/35.

Everything works fine but when they start testing the server goes down. Can you give any advice? Can we do something about this?
