No. Peer-type headers are reserved solely for the one and only exclusive use of true PEERS. The "peer-type" header is only a technical implementation of the inter-server communication protocol, which will not be opened to non-peer users. Inter-server information tags (X-LSV...) are DISCARDED if the file does not come from a peer that is present in the local list file. The reason is that if "everybody" was allowed to send X-LSVxxx tags and have them interpreted, they could easily create mailing loops, have valid mailfiles bounced to the postmaster, create problems in the distribution of the file, cause a "mailing loop detected" error, etc. As you may know, I don't like "half-peers" and I'm not going to implement anything that might encourage their use. I have nothing against people who don't want to peer because they feel they don't have time to find the necessary hosts, etc, but hierarchical links make me angry as they are more dangerous than peer links and not easier to set up conceptually -- it only takes you more time because the link must be done with an ADD command and the "Peers=" keywords must be modified on all the existing peers. Please, let's not start running backwards. Eric
