Looking for a good anti-spam filter

[BliXem]

Hello,

I'm running with a team an hosting company. Can I use your script to use it for a good anti-spam filter system?
We've got 6000 domains so my question is:

- Is there a way to add the domains? One-by-one isn't a solution . I think we can create an API with the servers to the anti-spam server. Or can we create a mysql database within Postfix to use it? We already have that running now on the Mailscanner server. I think this is possible.

I've i'm right, it's a out-of-the-box anti-spam filter, right? You doesn't need install Mailscanner, postfix, spamassassin yourself, only run the sh script in centos 6?

Yes, you can.

You may want to use several of these systems handing various groups of domains.

MariaDB is now available in 3.0.1.9, so you can use that with postfix.

You can bulk add domains to postfix using methods you may already have either to the transport file or to a database, depending on your needs.

Nice! Thanks for your reply. I will start with Centos 6 and the KS script.
Also the VPS from digitalocean. I hope this doesnt matter, your website says:

If you have the option partition the disk as:
512MB EXT3 /boot
LVM Physical volume for the rest (call it vg_00):
8GB / (call it lv_root)
1GB /tmp (call it lv_tmp)
4GB SWAP (call it lv_swap)
xxGB /var (call it lv_var) (the reset of your disk space)

Hope this doesn't matter.

A couple considerations for a vps...

Use may want to use this script instead...

https://raw.githubusercontent.com/E-F-A ... ut-ks.bash

Then, answer no when asked to run the build.bash script.

Edit /usr/src/EFA/build.bash at the end and remove or comment out the fillers.

Then run it.

Fillers? Do you have a example?

[shawniverson]

Yeah its these lines near the end. You don't want this to happen on a vps..so you want to either remove them or comment them out.

Code: Select all

    # zero disks for better compression (when creating VM images)
    # this can take a while so disabled for now until we start creating images.
    # TODO make this not happen if we run the script from a VPS install
    dd if=/dev/zero of=/filler bs=4096
    rm -f /filler
    dd if=/dev/zero of=/tmp/filler bs=4096
    rm -f /tmp/filler
    dd if=/dev/zero of=/boot/filler bs=4096
    rm -f /boot/filler
    dd if=/dev/zero of=/var/filler bs=4096
    rm -f /var/filler

Fixed the issue with no permission. In mod_security added:

SecRuleRemoveById 950109
SecRuleRemoveByID 981173
SecRuleRemoveByID 981249

#1 Is benign, it is an issue with clamav-unofficial-sigs. You can disable the specific sigs to suppress the errors, if desired.

Can I update this via yum?
