Multiple recipients for always_bcc

If you want to add multiple destination with always_bcc you cannot use default mechanism, aliases need to be used. With MSH Traffic Policy you don’t need to create additional entries in /etc/aliases.

If you would like to define selective always bcc for sender or recipients read this post.

Select messages

You need to select which messages should get additional BCC addresses. Go to Conditions tab, click button Add and select Message Sender menu. For our scenario we assume that we want to add BCC recipients to all messages which are from our domain, ie.

Add Envelope Recipient action

This action will work like “add bcc recipient”, it will add only envelope recipient without BCC header. Recipient of this message will not see whom also received this message.

In new opened window provide an address for the mailbox to which you want to forward messages. Now once again choose Add Envelope Recipient action. Add as many addresses as you want.

That’s it, now each message which is addressed from will be blindly forwarded to and mailboxes.
