someone spamming from my email addresses

[the_web_designer]

Hi,

Put this in legal but think it was the wrong section. I keep getting auto-responces for emails sent from my company email, but the thing is, I am not sending them. I have a net that catches any emails sent to my domain. So people are using things like [email protected] to send spam. Is there anything I can do about it?

Many thanks,

Jonathan Padhiar

I had this problem a while ago. It was caused by a virus on somebody elses computer which obtained email addresses and used them to send emails. It could have been anybody I had emailed at any time. It eventually dried up.

Yes, I had the same thing. Thousands of porn e mail was going out in my e mail address. I did contact my provider and made them aware of it just so they did not pull the plug on my account. It did eventually stop but not till after I got over 12,000 bounced e mails or nasty e mails back.

Grrr, nasty stuff. Hope my email addresses don't hit any spam filters

Hi,

Sounds like they are spoofing your domain in the email Reply To: address field rather than actually using your email system to send spam. Because you are using a catchall, as you have seen, you will get every reply even though the actual email address doesn't exist.

Nothing you can do about it really except stop using the catchall and only accept email to valid/active addresses in your domain.

This type of spoofing will not impact spam filters at the ISP, since your domain isn't actually sending the spam, only receiving replies.

Hope this helps,

Any one can do that using SMTP programming. Thats not new. This is done through anonymous mailer programs available on the web.

As mentioned earlier, disabling your catch-all will help prevent this

You could also look at configuring SPF and DomainKeys, too.

use DKIM . more info at http://www.dkim.org/

I had the same problem and simple line in DNS configuration solved this problem.

SPF does the job!
