    How to stop spam -- DEAD in its tracks!!

    I don't think so. That's an SPF error which basically indicates that the sender is using a relay when the server otherwise doesn't allow it. Step 4 here (https://powerproductsandservices.com/public/mailserver/Mailserver%20Security.pdf) explains it pretty well.

    How to stop spam -- DEAD in its tracks!!

    @Sherrie: I haven't had any issues with any settings reverting back to default, so I don't know what your issue might be. I would look in the email header for clues. @Sherrie and @Marco_B: Yes, you edit the file via your preferred method. I'm pretty sure that shortly after KnownHost...

    WHM 11.50 and Centos 5

    The warning 'implies' that some features may not work or may break? The verbiage is "To take full advantage of cPanel and WHM, we STRONGLY recommend that you use Centos 6." But I haven't been able to find anything that describes what 'full advantage' is versus ... I guess not 'full advantage'...

    WHM 11.50 and Centos 5

    Does anyone know what issues there are with running 11.50 on centos 5? The cPanel documentation says that centos 5 is technically supported, but the WHM main screen then gives a warning that you really better be on centos 6.

    Yes, the raw files are better for cut/paste. Wasn't able to figure out how to get 'code' in the pdf to work right with copy/paste unfortunately. Well, that's why I put the raw files out there. Regarding the changes (or change log), I update all of the documents and provide the change log for...

    How to stop spam -- DEAD in its tracks!!

    Hmm, that's step 2. I was thinking more along the lines of some of the ACL or security settings in step 3. If you want to seriously lock down your mailserver, check this out: https://forums.knownhost.com/threads/mailserver-security-whm-cpanel.3372/ :-) A reseller might think twice about...

    Greylisting if done properly, will retain a database of "known good mail servers" ... so that the wait only happens once per sender.

    How to stop spam -- DEAD in its tracks!!

    I can hardly wait to try the stock greylisting. I'm holding off on 11.50 for a while though. I'm curious to know exactly how it handles greylist tracking (by messageID+server hash or server only). Hopefully I'll have time to look into that soon (if that level of details are even documented at...

    Cool! There's some good stuff going on in those RBL's. :) I noticed that WHM/cPanel updates to ver 11.50 is being pushed out. I was under the impression that it's still has issues. Is knownhost on board with running this version now? I'm pretty anxious to try out the built-in greylisting.

    The first one (173.254.228.199) is on the barracuda list now ... greylisting may have gotten this one. The second (173.254.228.202) is also on barracuda list now ... The third one (173.254.228.205) is also on the barracuda list now ... The forth one (173.254.228.210) is also on the barracuda...

    How to stop spam -- DEAD in its tracks!!

    I noticed that after I setup the accept delay/sync ... I could detect that 15s delay in my own email client and was a little annoyed, so I added some common static IP's that I work from. :) You can do the same with your own IP numbers (ip number list delimited by a ":") if you detect the same...

    How to stop spam -- DEAD in its tracks!!

    I would be very interested in seeing the email headers for the spam that's getting through. My observations to date: 1. Could be because of not greylisting. Some spammer's roll through blocks of IP numbers and randomly generated domain names to stay ahead of the RBL's. But the greylisting...

    How to stop spam -- DEAD in its tracks!!

    I just noticed that, and you beat me to it!! Is KH recommending upgrade from 11.48 to 11.50? Has anyone tried out the greylisting in 11.50 yet? In the meantime, I fixed a few bugs in my greylist solution that hopefully didn't stump anybody. The updated guide is at the same link...

    How to stop spam -- DEAD in its tracks!!

    Yeah I saw that before I started on the greylisting work. We're still at 11.48 ... I wonder how long it will be before we see 11.50.

    How to stop spam -- DEAD in its tracks!!

    @Eric: It's pretty much all in WHM and/or via root level SSH ... not in each cpanel account separately. @Dion: I would expect that steps 1 - 6 would be sufficient for most people as it was for John above (and probably about as far as you'd want to go if you're a reseller). But I would also...
