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 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.
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: 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?

How can I found the spammer on our server?
one of our customer trying to send mail with a PHP file! but I cannot found this account, can you help me to found this user?
Hostmonster and Bluehost Spammer
What is the relationship between Hostmonster and Bluehost?
One spammer has a domain with an NS1.HOSTMONSTER.COM but their IP belongs to Bluehost.
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:
[url]
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?
in our case, HACKER no DELETE files...
He send Spam by POST to file.php
We have APACHE_suexec + PHP in SAFE_MODE=true;

On linux it is so easy to find the spam with qmail or postfix. Why mailenable it is so difficult
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?

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.
Someone f'in spammer has used my legitimate email address as the from address for their spam emails. Now I am getting hundreds of
"Mail delivery failed: returning message to sender" in my inbox.
I use cpanel to host the domain/email, is there anything I can do?
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.
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?
Server1 (www.domain.com)
ns1.domain.com
ns2.domain.com
Server2
ns3.domain.com
ns4.domain.com
i want to shift my domain to one server to another server and the problem is how can i shift my email accounts data to one server to another server.
View 8 Replies View RelatedI have a collocated server which I'd like to do some upgrades to. I'm having it shipped back to me so that I can do the upgrades myself. However, since I use this as my primary email server, I need help setting something up so I have no email downtime.
I have a cheap shared hosting account with DreamHost so one idea I have is to point the domain to their servers and handle things through there for a bit. This seems like the "brute force" way to do it though since I have to wait for DNS propagation and what not. Another idea was to use a service like DynDNS' MailHop BackupMX which does storage and forwarding. However, this service is kind of expensive ($30) considering I'm only going to use it a week or so.
i been getting these errors do not what they mean sinse i have never seen them

well we have a reseller pack due to some reasons all the mails from our sites are going to bulk/junk ..all scrits and webmails.... our mailserver is clean not backlisted and not even warned we tried many things ..but have not worked
so as a solution we have though of following ..are those possible and might work
1) as all sites mails are going to bulk i think they are using ip for that .ip of mail server..can we use another mail server with another ip ..with in existing dns address...just chaning ip of mail server ..and use another mail server whose mail are going to inbox...
is it possible
2) can we use smtp server to send mail ..we have smtp address of our isp and google smtp as well
can we use it to send all emails in our all websites...
is it possibles.....what can be problems
is there any other way ..without changing(service provider) of the reseller package
any way
