I would prefer adding an MX record to a host in the neighbourhood, and deliver by UUCP finally (or temporarily make the MX forwarder recognize itself by another name, i.e. add it to the Cw class in sendmail.cf). Depending on the default TTL of the zone where this host is in, the new MX should propagate in reasonably short time, and the MX could finally still serve as a fallback. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
