How To Stop Spammers From Using Your Domain/email To Send Out Spam?

May 15, 2008

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?

Stop Spammers From Spoofing My Email Domain

May 4, 2007

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) 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 "" as the "From:" address, but the message-ID has my domain name in it..


------ This is a copy of the message, including all the headers. ------

Return-path: <>
Received: from nobody by with local (Exim 4.63)
(envelope-from <>)

There's gotta be some way (make that 1204.. just got 4 more bounces) to block spammers from doing this. Could someone help a newbie out?

Best Way Send A Few Thousand Email Per Day- Not SPAM.

Oct 22, 2008

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.

How To Stop Spammers?

Jun 30, 2008

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?

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.

Dec 29, 2006

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.

Email Being Picked Up As Spam From Hosted Domains. Main Domain Is Ok

Jul 14, 2007

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, is my main name. Email can send without problem,, 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) and for all the child domains etc.

Do i need to ask the datacenter to add a reverse dns entry for

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

I know the ip isnt blacklisted because exactly the same email goes through when sending from the email addresses.

Email Security From Spammers

Oct 3, 2006

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?

Spammers Impersonating My Domain

Jul 4, 2008

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:

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?
