Hi All, I wake up this morning to find 180 e-mails in my inbox which are Mail Delivery Failure notices. In looking at the e-mails further I find that they haven't originated from my server but are supposedly from info@apchosting.co.uk.

If I am reading this correctly the spammer is sending the mail from "Received: from netmailinfo.net (unknown [61.84.243.91])"

61.84.243.91 is a korean Ip address. What steps do I take to stop this person sending e-mail out under my business domain name as I am sure I am going to get listed soon.

Many Thanks

Andrew

You can't do anything about it and you won't be listed if they didn't come from your IPs. It happens to everyone from time-to-time..

Ahh ok thanks, just annoying they I get all the replies.

As long as I don't get spam listed I don't mind too much.

Many Thanks

Andrew

You can't stop someone from using your email address in their From: headers, but you can use things like SPF. Hopefully the MTA on the other end knows SPF and will kick out messages like the one above.

Only 180? Count yourself lucky
