What Is This Email Spammer Trying To Accomplish
Sep 26, 2007
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.
Sep 26 09:26:03 host postfix/smtpd[15098]: NOQUEUE: reject: RCPT from unknown[12.171.150.130]: 554 5.7.1 <AutumnvagaryMontano@example.com>: Relay access denied; from=<> to=AutumnvagaryMontano@example.com proto=SMTP helo=<mdgen-print.marylandgeneral.org>
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.

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 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):
Quote:
Received: from andersenreesel by holderem.xxx.biz with local (Exim 4.23)
Received: (qmail 64859 invoked by uid 24901)
Received: from janislanhami by xxx.biz with local (Exim 4.26)
Received: (qmail 43829 invoked by uid 147); 08 Apr 2009 21:22:39 -0000
Received: from raphaelpinkertone by standei.xxx.biz with local (Exim 4.23)
Received: from imanoldelphine by dispatched.xxx.biz with local (Exim 4.23)
Received: from conrado by hostic.xxx.biz with local (Exim 4.23)
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?

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 setup my own LAMP server.
It is only used for my own domains so I want to be able to watch all mail that gets sent from my server, via php or otherwise.
Basically I just want to be able to personally monitor what mail is getting sent from my server so that I can watch for possible spammer activity.
I am using postfix and webmin.. I have sendmail installed to, but I don't think it is getting used..
I guess theres got to be a log somwhere... but I am not sure where it is?
I have postfix set to CC me of all mail that gets sent but, it doesnt seem to work all the time.. just for certain things..

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:

How did he do this? How to block this?

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.
Anyone have any good defense scripts to share?

My System is a Windows Server 2012 r2 with Plesk 12.
On this system i have installed MailEnable as my Mailserver.
So at the moment something is spam on this server, but i can't find out who is it.

[Code].....
The header is meaning that the spams come from root@, but there is no account with the name root@...
On linux it is so easy to find the spam with qmail or postfix. Why mailenable it is so difficult

I'm having difficulty sending an email to another email address (with a different domain) which is on the same VPS.The trouble is, on the other domain's VPS control panel, within the DNS settings, the MX records have been pointed externally (to an exchange server). Their email is turned off. But bizarrely, their mailbox is full.
It seems as though Plesk is ignoring the MX records, and sending MY email internally to the OTHER domain's mailbox on the same VPS.How do I get Plesk to send my mail to the correct EXTERNAL MX records?

One of my customers asked me if is possible technically to offer free email services.
Since he's going to launch a big portal he want to offer such things later, for all users.
Now, there are problems as:
a) if there is any possibility to compress emails similar with GMAIL or YahooMail or so, because i can't imagine the email is uncompressed
b) how can be handled email boxes over multiple (mail ?) servers if the HDD space needed would be larger than for one server HDD ?

I am having an email issue and I can not resolve. I am hoping for some assisstance here.
One of my local clients are not able to email each other in their office. (About 10 employess I believe)
They are using Outlook mail client, and using ISP's SMTP server. They are able to send/recieve email to other users externally, but not intenally.
Using webmail works perfectly fine.
I spoke with my host and the said everything is working fine. I checked with the ISP to see if they are blocking the IP address on the SMTP server. They said they were not.
I have a personal account on the same server and tried to send email to another local email account, and it did not work either. Tried to send email to my clients email and they did not recieve anything.
I am on the same ISP as my client, so Im still not sure if its the ISP or not.

I setup mail piping with Exim so that e-mails sent to a specific account be forwarded to my PHP script. It's not working properly, because when I send a mail to this account, it's bounced by the mailer daemon:
Code:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
pipe to |/home/user/public_html/support/parse.php
generated by support@mydomain.com
local delivery failed
In my /etc/valiases/domain.com file I have:
Code:
support@mydomain.com: "|/home/user/public_html/support/parse.php"
*: :blackhole:
What can be causing the error?

On one my servers, I'm receiving hundreds of spam emails that are clogging up the email queue to email addresses that do not exist.
For instance domain.com, I would get
bob@domain.com
liz@domain.com
325235@domain.com
You get the picture. How do I setup my server so that if there isn't an email address setup the email automatically gets deleted instead of trying to attempt to deliver it?

I have a client who has his own hosting account, and wants to leave his e-mail on his own hosting account, but his website on my hosting account.
On his own hosting he has created a sub domain called shop, and pointed its A record to the IP address of my server. On my server I've setup his domain name, and created the sub domain shop. That all works fine.
The problem I have is that the site under the shop domain needs to send an e-mail to sales@hisdomain.com. Now my server thinks the main domain is setup on my server, so it sends the e-mail to itself.
I'm justing wondering how I can get the server to point the mails back to his hosting?
A previous host I've used said they had to add the domain as a remote domain on the server, then they had to make some changes to /etc/localdomains because I was getting errors trying to send mails to the address.

I currently have a domain on Server 1 (Linux, Apache, Ubuntu, Matrix control panel).
This server does not have any spam filter, so I have moved all the email accounts to Server 2 (Linux, Apache, Fedora Core, Plesk) which does have a brilliant spam filter; and have changed the DNS record for mail.domain.com to the IP address for Server 2.
Emails are being successfully received on Server 2.
On Server 1, when an email is sent through SMTP to an address at that domain, it does not send it to Server 2, it gets delivered to the hosting account for the domain on Server 1. So what I am guessing is happening is that Server 1 detects the domain has an account on the server, and instead of looking up the DNS info for that domain, just assumes it is on Server 1.
What I need to do, is force Server 1 to send email for that domain to Server 2. Is this possible, and if so, how can it be achieved? If more info about the server is required for a solution please let me know and I'll provide what I can.
