(presuming no 'ssh to my shell server and use > pine/elm/mh/mailx) Authenticated-only SMTP on port 587 (or alternately 773 if you like being different) as per rfc2476 works great here, and we have several users who dial up from AOL when travelling. AOL translucently proxies outbound port 25 stuff in such a way that either smtp-auth or starttls (forget which, maybe both?) gets broken. Fixing mail clients to try port 587 *first* in the absence of configuration that specifically named a port would remove some of the support overhead for organizations that have to deal with Joe & Jane Luddite as end-users. Are you listening, Microsoft, Qualcomm, Apple? ---Rob
