I thought of that, but the headers are a bit confusing. The FROM header is saying "postmaster@xxxxxxxxxx", but the originating mail server isn't obviously one of theirs: Received: from ns0.webmasters.com (ns.serverleasing.com [66.118.156.161]) My guess is that Redhat (or whoever they buy their server space from) was twiddling with their spam filter this morning and it went a bit wrong for a while. But as mentioned elsewhere, it has indeed stopped happening now. It threw me a little because it's the first time I've actually tried to post to this list, rather than just read along... :) P.
