Transport Rule Condition to Act on a Recipient in BCC Field RRS feed

  • Question

  • We have a policy where certain administrative staff need to be blind copied on all emails sent to certain distribution groups. Since this could be either a traditional or dynamic distribution group, and because the people copied could change at any given time, we decided that achieving this functionality via Transport Rules seemed to make the most sense. The rule (in Exchange 2010, by the way) was:

    "When any of the recipients in the To or Cc fields is ',,' Blind Carbon Copy ''"

    This worked fine for the most part, until we discovered that if someone BCCs one of those groups, then of course the rule doesn't capture that. There are also no conditions specific to people who were BCC'ed. I thought I could tweak the rule to use the condition "If recipient's address contains specific words" and plug the addresses of the groups there. This of course works awesome if the recipient specified in the rule is a person, but if the address is that of a group, it doesn't work (this doesn't entirely make much sense to me as the rule should be pretty generic, but anyway...).

    Does anyone have any insight into this or able to offer any suggestions for workarounds?

  • If it's not a secret that the email is being sent to, why not just add them as a member of the group?

  • Because not all groups are static. We have some dynamic groups. While I could create a custom Recipient filter for that, it's not particular ideal because we have several of them that get updated annually to filter by new OUs, and the more we can lean on configuring these sorts of changes through EMC vs EMS, the less prone to error it becomes.

  • Hi,

    I tested it in my lab, and tried use any conditions in the Transport Rule I can think of, even message header. Unfortunately all these didn’t work to catch the message Bcc to a group.

    We probably should consider third party software, but I'm not sure whether they can achieve this.

    Best Regards.

  • That seems like a pretty huge concern, doesn't it? That anyone can circumvent email policies akin to this just by putting the address in the BCC field rather than the To or CC?

    Does anyone know if this functionality exists in Exchange 2013?
