One or more of the attachments (Full Clip.exe) are on
the list of unacceptable attachments for this site and will not have
been delivered.

Consider renaming the files or putting them into a "zip" file to avoid
this constraint.

The virus detector said this about the message:
Report: MailScanner: Executable DOS/Windows programs are dangerous in email (Full Clip.exe)

So, what does it mean? Somebody uses my domain that to send Spam and viruses? How can I protect myself and my domain?

The same thing happened to me. I contacted my host and they told me to check and see if I had my domain email set to "catch all" - meaning any email sent to my website if mis-spelled, I still would receive it. I did have it set to "catch all" which meant that anything sent to my site would come to me through email.

My host told me someone was using my domain address as a phishing attack. My host asked me to remove the "catch all" from my email. This stopped all those junk emails that were not delivered from being returned to me. I was receiving hundreds per day.

So, I can only receive emails now if properly addressed to webmaster or whatever real email I actually have set up.

Thats unfortunate, but at the same time, I did NOT want my site to be used by spammers/phishers and hurt my sites reputation.

You might want to talk to your host about this. My concern was that it was eating up my bandwidth as well!

Good luck,

Yes, I set catch all to one of my emails, so I have to disable this feature, because I'm tired of those letters. Thank you Ziggy.

You are very welcome - I know how annoying that is. Your host will be happy too!

Best,
