I've been getting a lot of "Undeliverable" emails sent to my email address. On these messages, the spammer is using my email on the "From" part of the email...... So whenever he sends out spam, the person(s) getting spammed think it's from me..... And the thousands of Undeliverable email error messages are also sent to me.
Is there a way to stop this from Happening? ....... Besides changing my email address?
Is there any way to stop spammers from spoofing my address? I've had issues ever since I started this server with getting bounced spam where the "From:" field was (jibberish)@mydomain.com which was annoying but not that constant.
I came online this morning to check my mail and had over 1200 e-mails and all of them have "online@wellsfargo.com" as the "From:" address, but the message-ID has my domain name in it..

I have a VPS and I am wondering if anyone knows any way in which to make it so that emails sent from the server are not seen as spam by hotmail and the likes.

way to send up to a few thousand emails per day.
These emails are simply replies to people contacting me first then I reply with ONE message from an autoresponder. No further contact is made unless they write me back again.
This is not really something that would work with aweber, getresponse, or a similar service.
And most email service providers seem to have a limit of 250/messages a day.
I'm guessing I will need a dedicated server for this?
Anything else I need on the dedicated server? I only have a few mailbox accounts I use that I access via outlook.
I was wondering if anyone has any methods to stop spammers? Currently i am keeping watch on the mail queue and making sure nothing unsual. I have in WHM configuration setup to not allow more 200 mail messages per account per hour but for some reason it will hit thousands. WHMCS does seem to suspend them automatically or maybe its because of WHM BUT only when its too late.
Any thoughts or suggestions?
Have a persistent spammer who kept emailing my clients, even non existent domain accounts and getting the bounced emails to be send to a particular yahoo address. I tried to block in all ways but can't seem to stop him. His spams are from all over the world. Any suggestions?

I can confirm that the person who is doing this IS NOT using the 'nobody' user because I am keeping a spam_log for that.
How else is a user able to use our server for spam? Please help as I would like to get this sorted ASAP.
suppose my domain is mydomain.com, my sendmail may send email to any domain name except local domain, say, sendmail may send email to hotmail, yahoo or any other domain name, but when send email to emailbox under mydomain.com, sendmail log will say domain not found.
My situation is my server does not have DNS service, my DNS service is outsourced, and MX record also is outsourced.
My mail server suddenly went into chaos. Everytime I send out an email it
retruns me back an email automatically telling me example:
"unrouteable mail domain "gmail.com".
"unrouteable mail domain "yahoo.com".
Etc.
I try to reinstall exim
#/scripts/exim4 --force
I even reboot the server but nothing works.
I have a problem to send email to idn domain names.
The error that I have is
Validation failed for: xxx@xxx [pid 111655 on line 754 of "/usr/share/psa-horde/imp/lib/Compose.php"]
One of my hosted domains have an email problem, every email account that is hosted on that site, is able to send and recieve email, but when sending to gmail or hotmail, it is delivered as SPAM.
Someone told me it is because this domain doesnt have a MX record at the DNS zone..
What is the sintax for the MX record ? I have enterd A(ddress) and CNAME records, but never MX records.. can anyone tell me how to do it so I can send mail in the way it should be.
i have a vps and although i can send mails without problem from my main root account, sending via any of the child accounts created for customers results in their email being picked up as spam (in hotmail at least).
To clarify, mydomain.com is my main name. Email can send without problem,
customersdomain.com, hosted on the same machine, when sending emails they are picked up as spam. The mx dns entries in the zone file are set (by default to) customersdomain.com. and for all the child domains customer1domain.com. etc.
Do i need to ask the datacenter to add a reverse dns entry for mail.mydomain.com?
Is this an issue with the mx records for the hosted domains? Should i change the hosted domaims mx entry on the customers domains to mail.mydomain.com?
I know the ip isnt blacklisted because exactly the same email goes through when sending from the mydomain.com email addresses.
I have two domains that I haven't set email up for yet. One is hosted on a good plan that uses cPanel. The other has some not-so-user-friendly interface.
Either case, I haven't set up email because I don't know what to seperate between truth and fiction. I know of the front end measures of cloaking an email link to your site using hex or some other hack so it doesn't show up to spiders and bots.
I also heard a rumor that using generic "webmaster@" on any domain is a surefire way for these bots to spam through. So is that true? Should I name my link like "thiswebmaster@" instead ? (or to that effect?)
What can I do to prevent too much (relatively speaking I guess) spam coming in?
I have a server that is sending spam, but I can not know who sent because the server not has installed suphp.
There is another option to see who sends spam?
For my site email address I get like 500 emails a day.
Is spam assassin really the only method?
i have server and on the server 150 website and more
someone upload mailer and send spam to online banking
i want know where this mailer on the server coz my server on nobody
i stoped sending from nobody from Tweak Settings till know what the account sent that and all message in Mail Queue Manager
what the solution?
any script to know that or method?
I'm receiveing tons of "Mail Delivery Failure" emails lately, like hundreds a day.
Today I opened a few to check what's going on... And basically these emails say a message could not be delivery due to a random error.
What intrigued me was that emails from my domain were the alledged sender or were on the reply-to field.
Those email accounts not even exist under my domain. And the spam messages were not sent from my server as it's clear in the body of the delivery error email.
So the situation is I have a spammer sending out thousands of emails a day impersonating my domain.
You can see a copy of the emails I'm getting here: http://cl1p.net/delivery_error
Why's the spammer doing this? Why the need to impersonate my domain?
And how can I stop him?
I think I might have a problem with my SPF rules, too loose! How to tighten it?
We have WHM 11 on the server.
Now the server is getting to many spam mails. We already have filters on the server, but we get spam mails with header which are not in English language. The header are normally in russian or arabic language.

I have been receiving a LOT more "unusual character" spam, where the entire email consists of something like this: .....
