As I mentioned before, the system is a LAN. The host I was trying to reach was in my /etc/hosts file, and my host.conf was set up to try hosts before bind, so it took a while to figure it out. The problem was in sendmail.cf (FreeBSD); The OI macro had to be commented out to avoid having sendmail use the BIND server at all times. The problem on the HP side was a bit silly. Although I was sending to the right address, the host name I was using did not correspond to that of myname on the FreeBSD side and was therefore being rejected by sendmail. ----------------------------------------------------------------------------- Robert Burns (rjbproc@vir.com) Mtl., Ca. -----------------------------------------------------------------------------
