Disable CLAM/D?
Hello, What's the best way to disable clam (everything clam-related: clam/clamd/unofficial signature related)? What other steps can I take to reduce memory consumption? I need every bit of memory I can spare. I've tried various settings to limit clam hog behavior to no avail. It's still taking too m...

Re: Download EFA 3?
EFA 3 worked fine on the tiny 512MB for years 8-) Will give 4.x a shot based on your advice. I saw this link to limit clamav memory: https://betatim.github.io/posts/clamav-memory-usage/ Update: after some work, I noticed that even with a 1GB RAM, clamd is killing the disk and slowing everything. Wit...

Download EFA 3?
Hello,
I recently lost my 3.x VM and would like to rebuild it. How can I download it?
p.s. I tried 4.x but it's too resource-hungry for my 512MB cloud VM.

Re: Upgrade Centos 6 to 7 with EFA-3?
I think it would make sense to do a forklift upgrade on a stable and supported OS. Like Ubuntu LTS.
I hope there is a roadmap to move away from CentOS, now that RedHat treats it like a step child.

I also noticed that CentOS 8 is EOL by end of the year. What is the roadmap? Can EFA work on Ubuntu 20 LTS?

Upgrade Centos 6 to 7 with EFA-3?
Hello, Is it possible to upgrade from CentOS 6.1 to 7.x without breaking EFA? Background: I have EFA-3.0.2.6 running on end-of-life CentOS 6.1. The VM works just great with 2GB RAM (low traffic) and I don't want to upgrade to 4.x due to its high RAM/CPU requirements (limited Host VM resources). I al...

Re: No longer processing spam
Found the reason.
In the file header_check I remarked the hold line. I was not aware that this line is crucial to the whole mailscanner-related functionality.
Recommend adding a warning text in the file next to the above line not to modify/remark it.

Re: No longer processing spam
I know because I get email in my inbox..
No more spam filtering. Everything that's not filtered by postfix filters goes through. Mailwatch stopped showing new mail. I think it stopped working around the same time I 'yum update' some php related stuff.
Please help

No longer processing spam

Looking at mailwatch I do see that since a week ago it no longer registers new mail - either good or otherwise. Everything else looks normal. Mailscann...

Re: mysql overloading system cpu/IO
Something here doesn't add up.
Other than the mailwatch web GUI functionality the VM is doing just fine with less than 0.9GB. Having to add 3 times that amount just for the mailwatch web gui seems unreasonable. I would argue that the system could benefit from mailwatch/mysql optimization..

Re: mysql overloading system cpu/IO
The most I have available is 2GB. I'll try it and post update. One note I'd like to keep in mind: The previous EFA VM was working fine with just 800mb ram, including mysql. Same hardware/Esx. Can't imagine that this VM needs 300%/400% more RAM. There is something else going on with mysql. Any though...

Re: mysql overloading system cpu/IO
As I mentioned:
1. I have an Exchange VM server running on that ESX and it's working just fine.
2. The EFA has been working fine for the first two months.
It is not the hardware nor the underline ESXi.
