I have recently been receiving reports from AOL's feedback loop that my server is sending out spam. I have checked the whole server, but cannot find anything strange.
There are some strange things with these feedback reports. I'll post a few lines below (i crossed out my domain with xxx):

The first issue i have is with the subdomains, like "dispatched", "standei", "hostic", etc. These subdomains do not exist on my system. Also, my server does not run the exim MTA.
Another issue i have is the "invoked by uid" statements with uid's 147 and 24901. These UID's do not exist on my system. The passwd file uid's go to around 110.
Apart from these strange things, the IP that is listed in the upper part of the headers:
Quote:
Received: from xxx.biz (xxx.biz [85.xxx.xxx.xxx])
The domain and IP address is correct there, which should indicate that the spam was sent from my system. Or wasn't it?
Now first I will say I have NO idea how such spamming works, how a punk can get on my server and sent emails out.
I have had a team to look at it they also did something, but now it happens again for the 5th time, what can i do, are there any software or tools one can use like a antivirus to check the server and how can I avoid such sh..
I host a vBulletin forum on a US server. I've been getting a lot of signups from one particular spammer, wanting to post about gold harvesting for WoW. I've blocked his IP's, however he keeps using proxies.
He constantly signs up under the name "Array"... Is there a way I can block him for good? I can't moderate user sign-ups, as I'm mostly away from my computer and can't moderate them all the time.

I just found posts every a few days from an apparent spammer "sagepowder" in my forum (not so popular and has nothing to do with skiing). The subject is always "new here".
The content is "Any snowboarders or skiiers on this forum? I am planning a trip to BC on a snowboarding trip next week" or "I am new here, just saying hello".
I checked the apache log and it doesn't seem to be a robot script posting this. i.e. it browses to the index page, picked up my hidden field that blocks robots, post new topic, the go back to index page.
What surprised me is that when I google this guy, I got 108,000 results with the same content on tons of forums! All with total post number of 1 or 2 on each forum: [url]
I recently moved web services for one of my hosted domains (let's call it example.com) from one server (let's call it .org) to another server (let's call it .net) example.com has been on .org for about 5 years. .org handled all example.com web services, and all email. I recently updated example.com's DNS record to point www.example.com and example.com to the .net server. I didn't change the MX record or mail.example.com to point to .net. Mail continues to be delivered normally to example.com on the .org server.
Except now spammers are hitting the .net server, e.g.
Is it normal practice for spammers to send dictionary attack based spam to a domain's server that doesn't even handle email? All the spam coming is clearly just random email addresses not based on anything that exsists at the domain, and most of the addresses are so very random I can't imagine they exsist anywhere.
For about a month or so now I have a domain I host under serious attack from what I think are spammers. It's a wordpress site, and they are getting big numbers of POST requests to the WordPress comments file, e.g.
Code:
POST /wp-comments-post.php HTTP/1.1 It's a well distributed attack, and I'm doing well with some scripts I wrote to block the requests to the wp-comments-post.php file. The real comment file has long since been moved, so any POST to the file gets firewalled. It's several thousand IPs from all over the place.
I don't believe it's a malicious attempt to bring the site down, but I'm guessing it's a blog comment spammer that has something set wrong and he's pounding this site to death by accident. I could be wrong on that though.
Sometimes my clients install untrusted scripts to their account what causes spamming, because these scripts sending high number of spam emails. Is there an automatically way to disable php mail function, or disable the account temporary?
This is the scenario, domain.com are setup on server1, however server2 also has the same profile of domain.com as we use ns3 and ns4 using domain.com. This works fine with the nameserver setup on server2.
However I encounter problems as the emails from server2 won't reach server1 as there are duplicate profile on server2.
My question is how do I setup the DNS in cpanel/whm from server2 so the emails from server2 will reach server1?
I have 2 servers both have cpanel. I want to use 2nd server's mysql in my site which is on 1st server. I think thats not that hard. I don't wanna do clustering as this is temproary.
if it's possible to use ODBC to connect to a Windows box from a Linux cPanel server. We have attempted connections from PHP (both as CGI as well as Apache module) and we get: Fatal error: Call to undefined function odbc_pconnect() in...
and
Fatal error: Call to undefined function odbc_connect() in...
I'm holding a dedicated server on my own and have about 6 sites to transfer to that server, some sites get heavy traffic (8k uniques per day)
what is more effective (since im the only one using the server anyway) creating one cpanel account and hosting all the domains under additional domains on that account with unlimited resources or creating a new cpanel account for each domain?
