cpolicyd and read delivery proof

[fferraro87]

Hi,

i'm using cpolicyd on my zimbra servers, and i use a policy for reject all email sent from other domains inside a group that i defined on cbpolicy.

so i have that policy :
Source -> !%group
Destination -> !%group

and inside "group" there are my domains.

Now, the problem is when a user want a read delivery proof because it is blocked from that policy because the sender of that proof is <> (empty), can i add an empty domain on "group" or what is the best solution in order to make it work again read delivery proof?

Thanks
