attachment attachments aware blocked buyer email eml executable form forwarded forwarding issue likely mail malware message postal potentially purchase received recent rejected report screening send service virus viruses work-around yahoo

I just received a rejected message with the following report: xxx@yahoo.com
This message has been rejected because it has a potentially executable attachment "Postal Mail Purchase.eml"
This form of attachment has been used by recent viruses or other malware.
Are you aware of this form of virus screening and do you have a work-around.

E-junkie does not send any attachments with the email.

It will most likely be buyer's email forwarding service which forwarded our email as an attachment and got blocked by yahoo.

It's not an E-junkie issue.
