Email Blocked By Bidefender

Hi,


We have been working with another company for some and this company uses bitdefender.


But all email from our company (cnx-translation.com) seem to be blocked by BitDefender software o nthe client side.


What may cause this? We only have have our logo and signature (with a link to our website) attached to the email.


Here the kind of error message we receive: (I changed the domain name of the other company).


Hi. This is the qmail-send program at virusgate1.test.net.th.


I'm afraid I wasn't able to deliver your message to the following addresses.


This is a permanent error; I've given up. Sorry it didn't work out.


<unit@test.net.th>:


203.148.252.235 failed after I sent the message.


Remote host said: 550 Rejected by BitDefender.
