I have now got some error messages from sendmail. If I comment out the SMAT_HOST line and rerun the m4, I get the following: Not Working (commented out SMART_HOST): Jan 11 11:50:22 eir sendmail[22798]: h0BBoLgI022798: from=<segfault@blueyonder.co.uk>, size=688, class=0, nrcpts=1, msgid=<1042286247.4768.11.camel@stimpy.angelnet.int>, proto=ESMTP, daemon=MTA, relay=stimpy.angelnet.int [192.168.3.100] Working (SMART_HOST set to ISP smtp server): Jan 11 11:50:22 eir sendmail[22800]: h0BBoLgI022798: to=<segfault@blueyonder.co.uk>, delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=30359, relay=smtp.blueyonder.co.uk.
