Reading the O'Reilly sendmail book it does appear to be saying that sendmail uses DNS for *everything*. I seem to have a workaround at the moment though so as that works there doesn't seem to be a lot of point in expending a huge amount more effort on this. The workaround (well, discovery of what sendmail thinks 'here' is) is that mail sent to <user>@isbd.net from my home system gets delivered locally. Thus if I put:- root: chris@xxxxxxxx at the end of /etc/aliases I get root's mail. I'd dearly love to know *why* sendmail thinks my home system is called isbd.net but I think that's lost in the guts of sendmail somewhere. There is no 'isbd.net' anywhere in my system, the only way that sendmail can be obtaining it is by removing the 'home' from 'home.isbd.net'. Out of interest a little 'C' test program from the O'Reilly Sendmail book which purports to get names in the way that Sendmail does produces the following output on my system:- hostname = 'home' canonical = 'home.isbd.net' alias: 'home' -- Chris Green
