This may happen when you re-TAG and TRANSFER a S&F file to RSCS. The origin userid@node will be lost and will become RSCS@localnode, and of course RSCS@UWAVM is not a trusted source at OREGON1 (note that in this context, 'trusted source' means mailer/gateway/mail-daemon, not RSCS machine). I don't know what happened, but to me it would seem that the file origin has been lost before reaching node OREGON1. Eric
