Hi,
I'm currently testing Sophos Email Advanced
We are getting a lot of bounce notifications from Sophos about emails that have been attempted to bulk providers who don't allow incoming email.
These are usually from auto-replies from users Out Of Office replies.
I know that it needs to be a Data Control Policy based on Message Attributes, but I'm unsure what to put in the Header Attribute Box (see below)
Thanks,
Craig
