Hi, RHL already comes with the cyrus-sasl libraries, so he should be OK. Joe's solution is probably the easiest, though. Are you saying that you've found a way to have sendmail authenticate to a smart host? If so, I'm listening. I don't need it myself because my addresses are static, so I just let sendmail send directly to the destination, but this could be a big help to those I support. Let me know. Thanks. -- Bill in Denver
