To avoid having our email processing servers blacklisted for SPAM we have implemented an outgoing spam filter on our hosting platforms, an outgoing email can be blocked for several reasons:

The email is considered SPAM.
Email is considered to contain a VIRUS

If you think it is a false positive we invite you to contact our technical department for a more precise analysis of the blocked email.

It happens that some of our clients' webhosts are compromised and are used without the owner's knowledge to send SPAM. To avoid the IP blacklist of our hosting platforms, we have chosen to implement anti-spam/anti-spam security for outgoing emails.
