How To Change :: This Message Was Created Automatically By Mail Delivery Software ...
May 18, 2008
We carried out a major clean up on our server but when i send out mail i get this message:
"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:
The mail server could not deliver mail to email@example.com. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries."
Would anyone know what i need to change, to have this working, just checking,
My mail server receives tons of messages directed towards bogus, non-existant addresses at my domain. When those addresses don't exist, it creates a reply email with the subject "Mail delivery failed: returning message to sender". How do I stop exim from doing this?
All our email account on our server work fine ! (Cpanel/whm)
As soon as we create a new account on any domain name, and we try to send a test mail from any email address (hotmail, yahoo, our internet provider etc.. ) we get a bounce back email with the following:
I have a problem with hotmail that outgoing message not reached by hotmail only . all other mail is ok and spf recoed is pass . DomainKey-Status: good (test mode) the server with softlayer and i take new server at softlayer and still problem
i take new server from theplanet and i see the same problem!
all microsoft hotmail support responde is same : We have identified that messages from your IP xx.xx.xx.xx are being filtered based on the recommendations of the SmartScreen filter. SmartScreen is the spam filtering technology developed and operated by Microsoft. SmartScreen is built around the technology of machine learning. SmartScreen's filters are trained to recognize what is spam and what isn't spam. In short, we filter incoming emails that look like spam. I am not able to go into any specific details about what these filters specifically entail, as this would render them useless.
i make what all on postmaster.live.com but no way msg's are sent from ssh . webmail , outlook express and nobody all same
and if there datacenter can Availability a server sending to hotmail without problem add offers
We are a company for hosting and most of our customer's are confuse of that problem
I'm receiving over 25 000 emails all the time... Someone from italy spamming emails, spam is not being sent from mine server but they are spoofing mine site as the sending domain so it looks like its comming from me, getting the bounce notices all the time... it also load my cpus more than a bit.
I'm trying to send mails to yahoo and hotmail from my vps and the result was the mail ended up in Spam folder in yahoo and didn't receive any mails in hotmail. When I check the Full MEssage Header in yahoo, the sender was "Sender: Nobody <firstname.lastname@example.org>" Do I have to set to a name or something ?
My rDNS and SPF was set up correctly, I think. domainkeys=neutral (no sig)
our company is ordering a new dedicated server and we are a little unsure what we should choose as far as the full hostname and nameservers of this one server.
This server will have a couple different websites on it, but really, there is only one BIG website on it... let's call it abcd.com.
While most would pick a hostname of host.abcd.com for instance, if at all possible, we would like the domain name part of the hostname to be something different than abcd.com. We own a domain name that doesn't point to anything yet (unuseddomain.com) and we were wondering if we could use that domain in our hostname.. host.unuseddomain.com.
And instead of using abcd.com as the domain name for our own nameservers (ie. ns1.abcd.com, ns2.abcd.com), we would like to again, use the unused domain name we own (unuseddomain.com) for the nameservers domain name: ns1.unuseddomain.com, ns2.unuseddomain.com.
Will this work? Is this perfectly acceptable?
Since the one website we really care about on this server (the one we got the server for in the first place) is abcd.com, is using the unuseddomain.com for the hostname and nameservers (as above) a bad choice in anyway regarding email deliverability? I understand that mail ISP's (hotmail, yahoo, etc.) do all kinds of checks on hostnames (PTR), etc... and we want to make sure that we aren't hurting ourselves in anyway by using an "empty" domain name that we own as our hostname's and nameserver's domain name.
For instance, if we send mail from the abcd.com account, it will use mail.abcd.com (220.127.116.11) as it's outgoing mail server... Hotmail will see this... do a reverse-dns lookup on 18.104.22.168 and see host.unuseddomain.com. See what I'm saying? It all will work, but will it toss up red flags?
i have just start my own dedicated server for two weeks, after some system migration, i expect the hosting will provide mail server for customer to send system notifications. but the hosting finally didn't provide, my OS is windows 2003 R2,
any hints for EXIM reject E-mail trying to be sent to an non-existent account on a domain hosted by me? I think the default configuration is to accept the E-mails and try to deliver, then it will fail and an E-mail will be sent to the sender but many times the sender is fake (spammer) and this message will rest on queue for some days...
I was thinking on some filter like "if ((!exist account@domain) && (!catchall domain)) reject"
but I don't know how to set something like that on EXIM
My host gave refuge to a ROKSO spammer and got the C-block listed in SpamHaus and cant get it removed.
So they mapped a new, clean IP to my server and I need to change the IP that my MTA is sending out under. Since I didnt set this up and the guy who did is not avaliable to me ATM, I cant seem to figure this out.
I have contacted hotmail asking why automated emails such as registration verification are being blocked and they said that my server's IP was on a blacklist for spam. I never spam and I do not think a bot has phished using my server's IP. Anyway, if I were to switch server IPs would that solve the problem?
I'm wondering if anyone else has experience with this, or if it's something easy that I'm overlooking.
I am on a VPS service (CentOS Linux) and I want my php mail function emails to send from a specified address. I've already manipulated the headers, so the emails do appear to come from the specified addres, but on mobile devices it comes up as email@example.com format. I would like this to read something like firstname.lastname@example.org
know which configuration files can change this default address?
When a newsletter tool or really any PHP script sends mail from a domain account it says it is from 'email@example.com' on behalf of the sender. if we send from the kensingt account it says it is from 'firstname.lastname@example.org' on behalf od sender. I would like to change this so it says it is from 'email@example.com' on behalf of sender and I have looked through the whm and cpanel settings and cannot find a place to do this.
I'm in the process of configuring my company's new server and I've hit a slight stumbling block. What's happening is that PHP is creating its sessions like normal with the exception of no permissions being set for them. This then means that errors are thrown up when PHP attempts to open the session files. Can anybody tell me why this is happening? I have set the sessions directory to octal 0777 for the time being.
I am designing a site for a client and in all the years I've done design etc, I've come up against a phenomenon with their VPS server they have. It's linux and uploading files I am using WS_FTP Home.
I am uploading files and folders to their public_html/domain.com/ (*I use domain here for their privacy) and in some folders (directories) after doing so, a mystery folder suddenly appears that is named 5" and as you enter that folder, you see the path directory show up "public_html" and if you go into that one, you come up to the domain.com folder again, and if you deeper into that one you start to see this phenomenon of mirroring folders of the one you go into. Example:
public_html/domain.com/images/5"/public_html/domain.com/images/file ***the file whether it's an image jpg, png, etc is created as the last directory as a folder, not a file. I should also mention that as you go deeper in the 5" mystery directory folder, you no longer see the path in the FTP anything past the 5" one even as you go further in.
Oh, and it doesn't allow you to delete these 5" folders regardless of what permissions. And this folder seems to show up in many areas of this website's directory structure...mostly where images are (don't know if that is just a coincidence).
So hope all this makes sense....anyone seen this before and what the cause could be? Their host doesn't seem to know the reason and says they cannot see it even though others can. They said it's the FTP program as the cause and not their server.
My comeback to that is that I've used this FTP for years and never before seen this happen. It's only with this one client's server.
I recently got a dedicated server (CentOS with WHM and cPanel) and I am a newbie when it comes to server admin.
I had a hard time with the proper configuration so that Fantastico would work (it took their admin a week to figure out their own installation).
In any case now I can use Fantastico to install scripts and the one I use the most is Joomla. There is a major problem though. So I create a new account in WHM (with root access or not), go to domain.com/cpanel, go to Fantastico and install Joomla. Then if I access files or folders through FTP using CoreFTP I can't change permissions (most of files or folders) and I can't edit files. (that's the case even for the accounts with root access).
I can perform those actions if I log into WHM with my main root account and change what I need using a module called Configserver Explorer that shows all the files on the server (without that module I would be lost - I don't know all those shell commands)
So can anyone help me with some proper configuration tips so that if I create user accounts (other then myself) they would have those permissions to edit or change stuff in their account?
I come from shared hosting and never had these problems. They were allowing add-on domains and I could copy entire sites to other domain names with one click. Now WHM says it's not a good idea to allow add-on domains. No idea why. Any advise one that?
This is twice I have found email addresses on the web that I have never created. Both domain names are the new extensions and I purchased them the first day they become public. .biz the other is .US
One of the domains I never even created a web page until yesterday. And today I find a German site using my domain as an email address. One note on this, this domain name is extremely unique and related to certain German ideas or thoughts.
I am thinking someone at the server created them and used them for their personal use. Is this possible?
Not only that, but I have sent email to these addresses and there was no bounce back. No bounce back meaning these are valid email addresses?
We've had someone starting nobody PERL procs on a box and we can't quite track it down or read the file to see what it is. What he does is to create a folder in /tmp, execute the script from there and delete the folder as soon as it's running (yes, /tmp is mounted noexec, makes no difference). We've managed to discover and block the IP that was doing this, but that's no fix. He hasn't been back since banning the IP...so far.
What we would like to do is see if anyone knows of (or can help create) a script that can watch the /tmp folder and copy newly created directories and thier contents to another dir (also notifying via email would be helpful) in order to see what the heck it's doing, and hopefully be able to figure out how it's getting in. Nothing in any logs this time, and the PERL process seems to be able to hide itself from PS. That bit worries me quite a lot, but none of the binaries appear to have been changed, and it doesn't appear we've been rooted in any way. Thoughts on this, ideas and suggestions welcome.
Failing that, is it possible without breaking the box to prevent the creation of new directories in /tmp? This I seriously doubt, but if all they need to do is create a folder and work from there, noexec is a joke.

Hacking mechanism: 1. this is not hacking indeed. This is usage of phpizabi engine imperfection
Usually the path till the admin area looks like this: ?L=admin.general.configure
If changing the path to ?L=admin//general//configure Then anyone can obtain full access to the admin area and can do everything he wants.
Similarly changing the path till any keyword file on the web site you can freely get the access to the database.
HOW TO CORRECT THIS ERROR:
mechanism: 1. Below I’ll show an example on how to correct the imperfection of phpizabi engine. This is only example and I recommend all the programmers to code by themselves their own mechanism of this error correction. Unque character of this mechanism will be one more obstacle against hacking.
So, in the very beginning of the script index.php we should put the following code:
It cleans everything from the query except “dots”, “letters” and “digits”.
2. All the folders in main directory of the web site which are located under the path /pages/ should not be accessible for opening! The easiest and fastest way is to set password access for all the folders in /pages/ through «Password Protect Directories» - this is client’s admin area on the hosting. You should set password to all except “chat” and “gallery”.
3. File upload:
By default any file can be uploaded for scripts phpizabi for dating web sites. They could be uploaded like a picture for gallery or attached file for other web site elements. Specially created *.php file which will be loaded at the server, can give full access to hacker and finally to walk away it from you!
I do not enclose the correction code of this error as you should restrict file uploading on the server by the class objects jpg/jpeg, gif and png.
